New Cloud Account Instance Dimension Bill Inspection¶

The cloud account instance dimension bill inspection helps users manage instance-level abnormal cost warnings, predict cost situations, and provides users with prompts for instances with high growth and high consumption, along with bill visualization capabilities, supporting multi-dimensional visualization of cloud service resource consumption.

New Alibaba Cloud Preemptible Instance Survival Inspection¶

Since the market price of preemptible instances fluctuates with supply and demand, it is necessary to specify the bidding mode when creating a preemptible instance. A preemptible instance can only be successfully created when the real-time market price of the specified instance specification is lower than the bid and inventory is sufficient. Therefore, inspecting preemptible instances for cloud assets is particularly important. Through inspection, when a preemptible instance is about to be released, it will prompt the latest price of the preemptible instance of the current specification in all available zones and the historical price of the preemptible instance, and provide appropriate handling suggestions.

Guance Billing Update¶

Guance billing optimizes Time Series billing logic, and metric data Data Retention Policy. Original每 300 条 3 元下调为每 1000 条 3 元.同时指标数据新增 3 天,7 天,14 天数据保存策略,指标集支持 自定义数据保存策略.

Time series statistics refer to the number of all combinations that can be formed based on tags in the metric data reported to the current workspace. Data retention policy is the data storage duration, which is the saving time of data reported to the current workspace. Data exceeding the storage duration will be automatically deleted.

Time series is a full statistics, meaning the daily generated time series will accumulate sequentially during the data retention policy period. The longer the data retention policy, the higher the time series cost.

This optimization allows you to more flexibly adjust the data retention policy of metrics by reducing the cost of time series and shortening the data retention policy of metrics, helping you save cost.

Guance Updates¶

June 6, 2022¶

Guance Billing Update¶

Guance billing optimizes Time Series billing logic, and metric data Data Retention Policy. Original每 300 条 3 元下调为每 1000 条 3 元.同时指标数据新增 3 天,7 天,14 天数据保存策略,指标集支持 自定义数据保存策略.

Time series statistics refer to the number of all combinations that can be formed based on tags in the metric data reported to the current workspace. Data retention policy is the data storage duration, which is the saving time of data reported to the current workspace. Data exceeding the storage duration will be automatically deleted.

Time series is a full statistics, meaning the daily generated time series will accumulate sequentially during the data retention policy period. The longer the data retention policy, the higher the time series cost.

This optimization allows you to more flexibly adjust the data retention policy of metrics by reducing the cost of time series and shortening the data retention policy of metrics, helping you save cost.

Guance Updates¶

June 6, 2022¶

Guance Billing Update¶

Guance billing optimizes Time Series billing logic, and metric data Data Retention Policy. Original每 300 条 3 元下调为每 1000 条 3 元.同时指标数据新增 3 天,7 天,14 天数据保存策略,指标集支持 自定义数据保存策略.

Time series statistics refer to the number of all combinations that can be formed based on tags in the metric data reported to the current workspace. Data retention policy is the data storage duration, which is the saving time of data reported to the current workspace. Data exceeding the storage duration will be automatically deleted.

Time series is a full statistics, meaning the daily generated time series will accumulate sequentially during the data retention policy period. The longer the data retention policy, the higher the time series cost.

This optimization allows you to more flexibly adjust the data retention policy of metrics by reducing the cost of time series and shortening the data retention policy of metrics, helping you save cost.

Guance Updates¶

New Jenkins CI Observability¶

Guance adds Jenkins CI observability. You can directly view the CI results in Jenkins through the Guance CI visualization function. The CI process is continuous integration. When developers push code, if they encounter problems, they can view all CI pipelines and their success rates, failure reasons, and specific failure links in Guance, helping you provide code update guarantees. For more details, refer to CI Visualization.

New Custom Viewer Chart Synchronous Search¶

Custom viewer adds chart synchronous search switch, used to determine whether the search conditions affect the chart query, enabled by default. When the search box has content, turn off the switch, and the chart query returns to the default state; turn on the switch, and the chart query is affected by the filter content.

New Network Topology and Service Topology Drill-Down Analysis¶

In the infrastructure network topology diagram, click the host/Pod icon, click "View Upstream and Downstream", to view the current node's upstream and downstream node associations. In the upstream and downstream nodes, click "Return to Overview" in the upper left corner to return to the original network topology diagram. Searching or filtering in the search box can filter associated upstream and downstream nodes, displaying matched associated upstream and downstream nodes based on the search or filter results. For more details, refer to the document Network View Upstream and Downstream.

In the service topology diagram, click the service icon, click "View Upstream and Downstream", to view the current service's upstream and downstream service associations. In the upstream and downstream services, click "Return to Overview" in the upper left corner to return to the original service topology diagram. Searching or filtering in the search box can filter associated upstream and downstream services, displaying matched associated upstream and downstream services based on the search or filter results. For more details, refer to the document Service View Upstream and Downstream.

New Delete Resource Directory Data and Index¶

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

Specify Resource Directory Classification: Only delete data under the selected object classification, will not delete the index
All Resource Directories: Delete all resource directory data and index

Note: Once all resource directories are deleted, all data and indexes of all infrastructure customs uploaded to the workspace will be deleted and cannot be recovered. All set resource directory classification data needs to be re-uploaded. Limited to 5 deletions of all resource directories per day.

For more resource directory introduction, refer to the document Custom.

New Viewer Snapshot View Entry¶

In Guance metrics, logs, events, APM, RUM, cloud testing, security inspection, CI visualization and other viewers, after saving the snapshot, you can directly click the view snapshot icon in the upper right corner to slide out and view the saved snapshots.

Supports snapshot name keyword search, fuzzy matching related snapshot names through keywords
The first one is the default view, does not support sharing, copying links, and deleting functions
Except for the first default view, other snapshots support sharing, copying links, and deleting functions. Click "Snapshot Name" to open the corresponding data copy in the current viewer

New Viewer Filter Condition Editing Function¶

In the Guance viewer search bar, when filtering by "field:value" method, supports clicking "field:value" to edit and modify the "field:value", and filter with the modified results.

Optimized RUM View Viewer Associated Link to Fetch/XHR¶

In the Guance RUM View viewer detail page, when switching to "Fetch/XHR", supports viewing every network request sent by the user to the backend application during access, including occurrence time, requested link, and duration.

If the network request has a corresponding trace_id, there will be a prompt icon before the request. Click the request to jump to the detail page of the corresponding link.

New Chart Data Loading High Performance Mode¶

Guance supports chart data loading high performance mode, disabled by default. Can be enabled by clicking the account in the lower left corner and selecting "High Performance Mode". After enabling high performance mode, all charts do not load dynamically, they are all loaded directly when clicking into the page, meaning when scrolling beyond the current page usage to view below, the charts are already fully loaded and can be viewed directly.

Note: High performance mode only takes effect for the current user viewing charts.

New Alert Configuration Event Notification Level¶

Alert configuration supports custom selection of event notification levels, including紧急,重要,警告,恢复,数据断档,数据断档恢复,数据断档视为恢复 7 choices, supports multiple selection, supports one-click clear options. After clearing, options are cleared, need to manually select corresponding values. For more alert configuration, refer to the document Alert Settings.

Other Feature Optimizations¶

Scene dashboard combination chart supports hide/show large title
Optimizes event detail page event type text display
Infrastructure list view adds sorting by field function
Log viewer adds hide distribution chart button
Viewer supports searching display columns by keyword, supports custom display columns as preset fields. Subsequent after cutting fields and uploading data through Pipeline, the uploaded data can be directly displayed.
In the built-in template library and built-in views, adds one-click viewing of corresponding integration documents, helping you quickly configure the corresponding collector
Built-in views除支持在查看器绑定链路服务,应用,日志源,项目,标签等相关视图外,新增支持自定义 key 和 value 绑定相关视图,同时支持服务侧滑详情页绑定内置视图
Optimizes notification target Lark robot, supports custom whether key security verification is required
When configuring the monitor, if the configured data range is smaller than the detection frequency, triggers a prompt that the configuration will have data gap issues

DataKit Updates (2022/05/26)¶

Pipeline adjustments, all data types can be additionally processed by configuring Pipeline
grok() supports directly extracting fields as specified types, no need for additional type conversion through cast() function
Pipeline adds multi-line string support. For very long strings (such as regular cuts in grok), readability is improved by writing them in multiple lines
The operation of each Pipeline can be directly viewed through datakit monitor -V
Adds Kubernetes Pod object CPU/memory metrics
Helm adds more Kubernetes version installation adaptations
Optimizes OpenTelemetry, HTTP protocol adds JSON support
When DataKit automatically corrects line protocol, it adds log records for correction behavior for easy debugging of data issues
Removes all string metrics from time series data
In DaemonSet installation, if the election namespace is configured, specific tags (election_namespace) will be added to the data of participating election collectors
CI observability, adds Jenkins support

Breaking changes¶

For Docker container log collection, need to mount the host (Node) /varl/lib path to DataKit (because Docker logs默认落在宿主机的 /var/lib/ below). In datakit.yaml, add the following configuration in volumeMounts and volumes:

```yaml volumeMounts: - mountPath: /var/lib name: lib
