Metrics Management¶

After completing the collection of metrics data, you can view all reported Measurement and related Metrics, labels, Time Series quantity, and data storage policies in Workspace > Metrics Management.

Measurement¶

Measurement refers to a collection of metrics of the same type. A Measurement can contain multiple Metrics and labels. Clicking on a Measurement allows you to view all available Metrics and labels under that Measurement on the details page, and you can quickly locate the required content using fuzzy search.

Metrics¶

Metrics help you quickly understand the overall operation status of the system, such as server CPU usage, website loading time, remaining disk space, etc.

Metrics consist of Metric names and Metric values, where the Metric name is an alias for the metric, and the Metric value is the specific numerical value collected. In Workspace > Metrics Management, clicking on the Measurement name will display the corresponding list of Metrics, including Metric names, field types, units, and other detailed information.

• Use to search for related Metrics based on keywords;
• Use to export the Metrics list as a CSV file to your local machine.
• Click the icon under Actions to perform one-click Metric analysis;
• Click to expand Metric data to edit the Metric configuration.

Editing Metrics¶

In Metrics Management, you can view all Metrics reported to Guance, including Metric names, field types, units, and descriptions, and customize the editing of units and descriptions. After saving, these changes will be applied in chart queries.

Use Cases¶

When querying Metrics, you can more easily perform data queries and analysis by viewing the Metric names, field types, units, and descriptions. For instance, when performing chart queries or Metric detection in monitors, you can view the detailed information of Metrics in real-time.

Labels¶

Labels help you correlate data from different sources. Guance supports unified reporting of all Metrics, logs, and trace data to the workspace. By tagging collected data with the same labels, you can perform correlation analysis to quickly identify and resolve potential risks.

Labels are collections of attributes used to identify the properties of data points, consisting of label names and label values. A data point can have multiple labels. In Workspace > Metrics Management, clicking on the Measurement name will display the corresponding list of labels, including label names, statistics of label values, and descriptions.

• Click to search for related labels based on keywords;
• Click to export the label list as a CSV file to your local machine;

Use Cases¶

When querying Metrics, you can quickly understand the meaning of labels by viewing their descriptions. For example, when performing chart queries or Metric detection in monitors, you can view the description information of labels in real-time. Guance provides default system fields/label descriptions, which you can replace according to your needs in Field Management.

Time Series¶

In the current workspace, the number of combinations of Metrics data based on labels is dynamically calculated. In Guance, Time Series are composed of Metrics, tags (fields), and data storage duration. Among them, the combination of "Metrics" and "tags (fields)" serves as the primary key for data storage.

Metrics Storage Policies¶

Metrics storage policies are divided into two types:

• Global settings at the Metrics workspace level;
• Custom settings for specific Mearsurements.

Modify Policies¶

Custom settings for Mearsurements take precedence over global settings. That is, after setting custom data retention policies for a Measurement, changing the global settings does not affect the data retention policy for that Measurement.

Note:

• After modifying the data retention policy for a Measurement in Metrics Management, the corresponding Measurement data stored in the global workspace policy will be deleted and cannot be recovered. Be cautious when performing this operation. If you modify the data retention policy for a Measurement again, the data under the previous policy will also be deleted.
• After modifying the data retention policy for a Measurement, its data will be stored separately. At this point, changing the global data retention policy for workspace Metrics will not alter the retention policy for that Measurement.
• After modifying the data retention policy for a Measurement, if you revert it to the global default retention policy, the Measurement will be re-stored in the global database. At this point, modifying the global data retention policy for workspace Metrics will synchronize the retention policy for that Measurement.
• After modifying the data retention policy for a Measurement, even if the global and Measurement retention policies are set to the same duration, the Measurement data will still be stored separately and will not be stored in the global database.

Global Settings for Metrics¶

In Manage > Settings > Risky Operations, you can view the global data retention policy for the Metrics workspace. The default data retention period is 7 days, including options for 3 days, 7 days, 14 days, 30 days, 180 days, and 360 days.

For more details, refer to Data Storage Policy.

Custom Settings for Mearsurements¶

In Metrics Management, you can view and customize the data retention policy for Mearsurements.

Click the button in the action bar to customize the data retention policy for a Measurement. Options include: 3 days, 7 days, 14 days, 30 days, 180 days, and 360 days. If no custom settings are applied, it defaults to the global data retention policy for Metrics.

Note:

• Only workspace owners can configure data retention policies for Mearsurements, and the Free Plan does not support custom data retention policies;
• After modifying the data retention period for a Measurement, the data under the previous policy will also be deleted and cannot be recovered.
