December 29, 2022¶

Guance Updates¶

Added MFA Authentication Management¶

Guance provides MFA authentication management to add an extra layer of security protection beyond account usernames and passwords. After enabling MFA authentication, you need to perform a second verification during login, helping improve account security. For more details, refer to the documentation MFA Management.

Guance supports configuring an IP whitelist for workspaces to restrict visitor users. After enabling the IP whitelist, only IPs from the whitelist can log in normally, and all other source requests will be denied access. For more details, refer to the documentation IP Whitelist.

Note: The IP whitelist is only configurable by administrators and owners. Additionally, "owners" are not subject to IP whitelist access restrictions.

Added Service Network Topology¶

In K8S environments, you can use the Service network topology diagram to view request relationships, response times, error rates, etc., between various Services in the K8S environment. When discovering connection issues with a particular Service, you can click to view the corresponding logs of that Service to pinpoint problems. For more details, refer to the documentation Service Network.

Smart Inspection Updates¶

Official Smart Inspection Discontinued¶

Official smart inspections for "memory leaks", "application performance detection", and "disk usage" have been discontinued as of today. Users can configure self-built inspection scripts.

Added Cloud Account Instance Dimension Billing Inspection¶

Cloud account instance dimension billing inspection helps users manage abnormal cost warnings at the cloud service instance level, predict cost situations, and provide high-growth, high-consumption instance prompts and bill visualization capabilities, supporting multi-dimensional visualization of cloud service resource consumption.

Added Alibaba Cloud Preemptible Instance Survival Inspection¶

Due to fluctuations in market prices for preemptible instances, it is necessary to specify a bidding model when creating a preemptible instance. If the real-time market price for the specified instance specification is lower than the bid and there is sufficient inventory, the creation of a preemptible instance can succeed. Therefore, it is particularly important to inspect preemptible instances for cloud assets. Through inspection, when it is detected that a preemptible instance is about to be released, it will prompt the latest prices for all available zones of the current specification preemptible instance as well as the historical prices of this preemptible instance and provide appropriate handling recommendations.

For more smart inspection updates, refer to Smart Inspection Update Logs.

August 18, 2022¶

Guance Updates¶

Guance Billing Update¶

Guance has optimized the billing logic for Time Series and the data retention strategy for metric data. The original cost of 3 CNY per 300 time series has been reduced to 3 CNY per 1000 time series. Simultaneously, new data retention strategies for 3 days, 7 days, and 14 days have been added, and metric sets now support custom data retention strategies.

The time series count represents the total number of combinations that can be formed from labels in the reported metric data of the current workspace. The data retention strategy refers to the storage duration of the reported data in the current workspace. Data exceeding the retention period will be automatically deleted.

Time series statistics are cumulative during the data retention period. The longer the retention period, the higher the time series costs.

This optimization allows you to adjust the data retention strategy more flexibly, helping you save costs.

Guance Updates¶

Added Jenkins CI Observability¶

Guance has introduced Jenkins CI observability, allowing you to directly view CI results in Jenkins through Guance's CI visualization feature. CI processes involve continuous integration. When developers push code and encounter problems, they can view all CI pipelines, success rates, failure reasons, and specific failure stages in Guance, providing code update assurance. For more details, refer to CI Visualization.

Added Custom Viewer Chart Sync Search¶

Custom viewers have added a chart sync search toggle to decide whether search conditions affect chart queries, which is enabled by default. When there is content in the search bar, turning off the toggle returns the chart query to its default state; turning it on makes the chart query influenced by the selected filters.

Added Network Topology and Service Topology Drill-down Analysis¶

In the infrastructure network topology map, click on host/Pod icons and select "View Upstream/Downstream" to see the upstream/downstream node associations. In the upstream/downstream nodes, click the "Return to Overview" icon in the top-left corner to return to the original network topology map. Use the search bar to filter associated upstream/downstream nodes, displaying matches based on search or filter results. For more details, refer to Network View Upstream/Downstream.

In the service topology map, click on service icons and select "View Upstream/Downstream" to see the upstream/downstream service associations. In the upstream/downstream services, click the "Return to Overview" icon in the top-left corner to return to the original service topology map. Use the search bar to filter associated upstream/downstream services, displaying matches based on search or filter results. For more details, refer to Service View Upstream/Downstream.

Added Deletion of Resource Directory Data and Indexes¶

Guance supports owners and administrators deleting specific resource directory classifications and all resource directories. Enter "Management"-"Basic Settings", click "Delete Resource Directory", then choose the deletion method to delete the corresponding object data.

Specific Resource Directory Classification: Only deletes data under the selected object classification without deleting indexes.
All Resource Directories: Deletes all resource directory data and indexes.

Note: Once all resource directories are deleted, all data and indexes reported to the custom infrastructure will be deleted and cannot be recovered. All set resource directory data needs to be re-reported, with a daily limit of 5 deletions for all resource directories.

For more information on resource directories, refer to Customization.

Added Snapshot Viewing Entry for Viewers¶

In Guance indicators, logs, events, application performance monitoring, user access monitoring, cloud testing, security checks, CI visualization, etc., after saving snapshots, you can directly click the view snapshot icon in the top-right corner to unfold and view already saved snapshots.

Supports keyword searching for snapshot names using fuzzy matching.
The first one is the default view and does not support sharing, copying links, or deletion.
Except for the first default view, other snapshots support sharing, copying links, and deletion functions. Clicking the "Snapshot Name" opens the corresponding data copy in the current viewer.

Added Filter Condition Editing Functionality in Viewers¶

When filtering using "field:value" in the Guance viewer search bar, you can click "field:value" to edit and modify the "field:value" and apply the modified result for filtering.

Optimized User Access View Viewer Linkage to Fetch/XHR¶

In the Guance user access monitoring View viewer detail page, switching to "Fetch/XHR" allows you to view each network request made by the user to the backend application during their visit, including occurrence time, request trace, and duration.

If a network request has a corresponding trace_id, a hint icon appears before the request. Clicking the request will redirect to the corresponding trace detail page.

Added High-performance Mode for Chart Data Loading¶

Guance supports high-performance mode for chart data loading, which is disabled by default. You can enable it by clicking on the account in the bottom-left corner and selecting "High-performance Mode". After enabling high-performance mode, all charts do not dynamically load. Instead, they load simultaneously upon entering the page, meaning all charts are fully loaded when scrolling down beyond the current page, allowing direct viewing of displayed results.

Note: Enabling high-performance mode applies only to the current user viewing the charts.

Added Customizable Event Notification Levels in Alerts¶

Alert configurations support customizing event notification levels, including critical, important, warning, recovery, data gap, data gap recovery, and considering data gaps as recovery. Multiple selections are supported, and you can clear all options with one click. After clearing, you need to manually select the required values. For more alert settings, refer to the documentation Alert Configuration.

Other Functional Optimizations¶

Scene dashboards allow hiding/showing large titles for combined charts.
Optimized event detail page event type text display.
Added sorting function for infrastructure list views by fields.

Built-in views support binding linked service, application, log source, project, label, etc., in addition to supporting custom key and value bindings for related views. Also supports binding built-in views in service side panels.
Optimized Lark robot notification targets to support optional secret key verification.
When configuring monitors, if the data range is less than the detection frequency, a warning is triggered indicating potential data gaps.

DataKit Updates (2022/05/26)¶

Pipeline adjustments allow all data types to be additionally processed through Pipeline configuration.
grok() supports extracting fields directly as specified types without needing cast() function for type conversion.
Pipeline supports multi-line string, improving readability by writing long strings (e.g., grok patterns) across multiple lines.
Each Pipeline's runtime status can be viewed directly via datakit monitor -V.
Added Kubernetes Pod object CPU/memory metrics.
Helm added more Kubernetes version installation compatibility.
Optimized OpenTelemetry, added JSON support to HTTP protocol.
DataKit logs record auto-correction behavior when correcting line protocol to facilitate debugging data issues.
Removed all string metrics from time series data.
In DaemonSet installations, if the election namespace is configured, all collectors participating in the election will add specific tags (election_namespace).
CI observability added Jenkins support.

Breaking Changes¶

For Docker container log collection, the host machine (Node) /var/lib path must be mounted into DataKit (as Docker logs default to /var/lib/). In datakit.yaml, add the following configuration to volumeMounts and volumes:

volumeMounts:

Added Scenario Custom Viewer Log Source and Filter Linkage¶

The data range in scenario custom viewers has added filtering functionality based on log sources, allowing you to filter fields under the selected log source, supporting matching multiple fields. Combined with search and grouping, this enables further filtering of log data.

Added Copy Event Content as JSON Format in Event Detail Page¶

On the event detail page, you can click the "Copy Complete Event Content" button to obtain all critical data corresponding to the current event. If a monitor is configured with associated dashboards, you can click the "Associated Dashboard" button to navigate to the corresponding dashboard.

In the Associated Information section of the event detail page, if multiple expression queries (of the same object type) are configured for "Log Detection," the associated information supports tab switching between multiple expression queries. If there are two expression queries A and B, the relationship information will include tabs A and B for switching views.

Added Log Data Desensitization Handling¶

Guance has added log data desensitization handling. After log data is reported to Guance workspaces, some sensitive information may exist, such as IP addresses and user information. These can be desensitized by configuring sensitive fields.

Note:

Desensitized data can only be viewed by workspace administrators and above; standard and read-only members cannot view desensitized information.
Configuring sensitive fields can only be done by workspace administrators and above; standard and read-only members can only view configured sensitive fields.

For more details, refer to the documentation Data Permission Management.

Optimized Log Viewer and Detail Pages¶

Guance log viewer now defaults to displaying "time" and "message" fields. This update supports hiding the "message" field.

In the log detail page, log content automatically displays in Json and text modes based on the message type. If the log does not have a message field, the log content part will not be displayed. Log content supports expanding and collapsing, with the default being expanded. Collapsed state shows only one line height.

Extended fields display all related fields of the log, supporting "copy" and "add to filter" for quick filtering.

Added Network Data Detection Monitors¶

Network Data Detection monitors network performance metrics within the workspace. By setting threshold ranges, it triggers alerts when metrics reach thresholds. Guance supports setting alerts for individual metrics and customizing alert levels. In Monitors, click "+ New Monitor" and choose "Network Data Detection" to enter the detection rule configuration page.

Optimized Built-in View Binding Functionality¶

Guance built-in views include system views and user views. This update cancels the ability to bind system views directly as viewer views, supporting only binding user views as viewer views.

Added Pod Network Details and Network Distribution¶

Pod networks support viewing network traffic between Pods. Based on IP/port, you can view network traffic and data connections between source IPs and target IPs, visualizing real-time displays to help businesses monitor business system network states, quickly analyze, track, and locate faults, preventing or avoiding business disruptions due to network performance degradation or interruptions.

Pod network data is reported to Guance consoles after successful collection. In "Infrastructure"-"Containers"-"Pod" detail pages under "Network," you can view all Pod network performance monitoring data in the workspace. For more details, refer to Pod Network.

In "Infrastructure"-"Containers"-"Pod," click the small icon in the upper-left corner of the network distribution chart to switch to viewing Pod network distribution. In the "network distribution chart," you can visually query network traffic between Pods in the current workspace, quickly analyzing TCP latency, TCP fluctuations, TCP retransmission counts, TCP connection counts, and TCP closure counts between different Pods. For more details, refer to Pod Network Distribution Chart.

DataKit Updates¶

DataKit collector added support for SkyWalking, Jaeger, and Zipkin data sampling strategies.
DataKit collector added support for OpenTelemetry data ingestion.
DataKit documentation library added documents introducing overall log collection methods, including collecting logs from disk files, calling environment APIs to collect logs, pushing logs remotely to DataKit, and sidecar-style log collection.

Breaking Changes¶

2022/03/22

Significant adjustments have been made to Tracing data collection, involving several incompatible changes:
- DDtrace configuration field ignore_resources in the original conf must be changed to close_resource, and the field type changes from array ([...]) to dictionary array (map[string][...])
- Original DDTrace data tag type field is changed to source_type

2022/03/04

For old versions of DataKit with RUM enabled, you need to reinstall the IP library after upgrading, as the old IP library will no longer be usable.

2021/12/30

Old versions of DataKit can no longer push new upgrade commands using datakit --version. Use the following commands directly:
Linux/Mac:

DK_UPGRADE=1 bash -c "$(curl -L https://static.guance.com/datakit/install.sh)"

Windows

$env:DK_UPGRADE="1"; Set-ExecutionPolicy Bypass -scope Process -Force; Import-Module bitstransfer; start-bitstransfer -source https://static.guance.com/datakit/install.ps1 -destination .install.ps1; powershell .install.ps1;

For more DataKit updates, refer to DataKit Version History.

EthTool metrics include network interface inbound/outbound traffic, inbound/outbound packets, discarded packets, etc.

Added Host System Conntrack Integration Documents and Views¶

Conntrack performance metrics include successful search entries, inserted packets, connection counts, etc.

February 22, 2022¶

Added Log Configuration Pipeline Script¶

Pipeline is used for log data parsing, defining parsing rules to split heterogeneous log formats into structured data that meets our requirements. Guance provides three methods for text processing in log Pipelines:

DataKit: After installing DataKit on servers, configure the DataKit log collector and corresponding pipeline files in the terminal tool to process text data.
DCA: DataKit Control APP is a desktop client application for DataKit. Install it first, and then you can view and edit default built-in log pipeline files in DataKit and manually add custom pipeline files.
Pipelines: Support manual configuration and viewing of log pipeline files in Guance workspaces without needing to log into the DataKit server for operations.

Added IFrame Chart Component¶

Guance added an IFrame chart component supporting HTTPS or HTTP link configurations. In the IFrame URL, you can input external URLs directly for viewing, or use template variables for viewing. For more configuration details, refer to the documentation IFrame.

Added Event Detail Historical Records and Associated SLO¶

In the event detail page, the basic attributes, status & trends, and associated events layout has been optimized, and historical records and associated SLOs have been added. Clicking the event name in the anomaly event list allows you to view these details.

The newly added event history supports viewing detection object hosts, anomaly/recovery times, and duration.

If SLO is configured in monitoring, you can view associated SLOs, including SLO name, achievement rate, remaining quota, target, etc.

Default Absolute Time Enabled When Saving Snapshots¶

Guance now defaults to enabling absolute time when saving snapshots.

If absolute time is selected when saving a snapshot, the shared snapshot will show the saved snapshot's absolute time. For example, if you saved a snapshot choosing the last 15 minutes and opened the snapshot link at 14:00, it will show the previous absolute time data.
If absolute time is not selected when saving a snapshot, the shared snapshot will show the saved snapshot's absolute time. For example, if you saved a snapshot choosing the last 15 minutes and opened the snapshot link at 14:00, it will show data from 13:45 to 14:00.

For more snapshot sharing details, refer to the documentation Snapshots.

Optimized Data Gap Event Configuration and Trigger Condition Unit Prompts in Monitors¶

Guance added three data gap status configurations: "Trigger Data Gap Event," "Trigger Recovery Event," and "Do Not Trigger Event."

For metric-type data monitors, you need to manually configure the data gap handling strategy.
For log-type data monitors, the default recovery event strategy "Trigger Recovery Event" does not require configuring data gaps, and the recovery event cycle is obtained from the "Normal" condition cycle.

Optimized Metric Expression Calculation Units in Chart Queries¶

Guance optimized the logic for calculating units in chart queries. If query A has units, the result of query A plus a number retains the same units. For example, if A's unit is KB, then A + 100 also uses KB as its unit. For more details, refer to the documentation Chart Queries.

Added "Time Series" Pay-as-you-go Mode¶

Guance added a "Time Series" pay-as-you-go mode and optimized the "DataKit + Time Series" pay-as-you-go mode. For specific billing modes, refer to the documentation Pay-as-you-go.

Other Optimization Features¶

Chart queries for data sources such as logs, application performance, security checks, and network support full selection (*);
Optimized chart query text, button styles, and text prompts;
Iconified workspace operation buttons like edit, delete, etc.;
Other UI display optimizations.

January 20, 2022¶

Added Open API and API Key Management¶

Guance supports obtaining and updating workspace data via Open API interfaces. Before calling API interfaces, you need to create an API Key as an authentication method. For more details, refer to the documentation API Key Management.

Added Metric Dictionary and Metric Unit Management¶

After metric data collection, you can view all collected metric sets and their metrics and labels in Guance workspaces under "Metric Dictionary". You can manually set units for custom metric data. For more details, refer to the documentation Metric Dictionary.

Metrics help you understand overall system availability, such as server CPU usage, website load times, etc. Combined with Guance's provided logs and traces, they help you quickly pinpoint and resolve faults.
Labels help correlate data. Guance supports uploading all metrics, logs, and trace data uniformly to the workspace. By tagging the collected data with the same labels for correlation queries, you can perform correlation analysis to identify and resolve potential risks.

Added Funnel Chart for Scene Charts¶

Funnel charts are generally suitable for flow analysis with standardized processes, long cycles, and multiple stages. Comparing data across stages can intuitively highlight issues. Additionally, funnel charts are suitable for website business flow analysis, showing the final conversion rate from entering the website to completing a purchase, as well as conversion rates at each step. For more details, refer to the documentation Funnel Chart.

Added Saving Dashboards to Built-in Views and Binding Label Data¶

After creating a dashboard view, you can click the "Settings" button and choose "Save to Built-in Views" to save the dashboard view to the "User Views" in built-in views.

When saving a dashboard view to built-in views, you can choose binding relationships, such as selecting "label". After saving to built-in views, you can view the saved dashboard view under "Management"-"Built-in Views"-"User Views". Since "label:" binding was set, you can view bound built-in views in the host/container detail pages where "Label Attributes" have been set in infrastructure. For more details, refer to the documentation *Saving Dashboards as Built-in Views**.

Added Container Detail Page Association with Pod¶

In container detail pages, you can view related Pod (associated field: pod_name) basic information and performance metrics within the selected time component range. For more container association queries, refer to the documentation Container.

Note: To view related Pods in container details, you need to match the "pod_name" field; otherwise, you cannot view the related Pod page in container details.

Added Monitor Group Management¶

Guance added the grouping feature, allowing you to customize meaningful monitor combinations when setting up monitors. You can filter monitors via "Groups" for easier management.

Note: - Each monitor must select a group upon creation, defaulting to "Default Group". - When a group is deleted, monitors under that group automatically revert to the "Default Group".

Added Format Configuration for Log Viewers, Table Charts, and Log Stream Charts¶

Guance added format configuration, allowing you to hide sensitive log data or highlight important log data, and perform quick filtering by replacing original log content. Format configuration is supported in log viewers, table charts, and log stream charts.

Optimized Mute Management, Adding Disable/Enable Rules¶

Guance added mute rule disable/enable functionality to quickly manage mute tasks. For more details, refer to the documentation Mute Management.

Enable: Mute rules follow normal procedures.
Disable: Mute rules do not take effect; if the mute notification policy selects "xx minutes before" and the mute notification operation has not yet been executed, the notification will not execute.

Note: Enabling/disabling rules generate audit events, which can be viewed under "Management"-"Basic Settings"-"Audit Logs" in Guance workspaces.

Added Log Pipeline Usage Manual¶

Guance added a log pipeline usage manual to help you understand how to use DataKit's built-in debugging tools to assist in writing Pipeline scripts.

# Debugging script example
datakit --pl datakit.p --txt '2022-01-12T18:40:51.962+0800 WARN diskio diskio/input.go:320 Error gathering disk info: open /run/udev/data/b252:1: no such file or directory'

# Successful extraction example
Extracted data(drop: false, cost: 3.108038ms):

  "msg": "Error gathering disk info: open /run/udev/data/b252:1: no such file or directory",
  "time": 1641984051962000000
}

Added Outer Functions in DQL¶

Guance added two outer functions rate() and irate().

rate(): Calculates the average change rate of a metric over a specified time range. Suitable for alerts and slowly moving counters.
irate(): Calculates the instantaneous change rate of a metric over a specified time range, suitable for drawing volatile, fast-changing counters.

For more details, refer to the documentation DQL Outer Functions.
