Metrics Management¶

After completing metrics data collection, you can view all reported measurements and their associated metrics, tags, time series statistics, daily day-over-day changes, and data storage policies in Metrics Management.

Measurement¶

A measurement is a collection of similar metrics, containing multiple metrics and tags. A single measurement displayed by the system includes the following information:

• Metrics
• Tags
• Time Series Statistics

Metrics¶

Metrics reflect the operating status of a system (e.g., CPU usage, page load time, etc.) and consist of a metric name (identifier) and a metric value (specific numerical value).

Click the measurement name to view complete metric details (name/type/unit, etc.), and the following operations are supported:

• Filter metrics based on keywords in the search bar;
• Export the metric list as a CSV file;
• In the operation column, support one-click metric analysis;
• Click to expand metric data, where you can edit metric configuration.

Tags¶

The attributes of the data point collection object are identified through tags, which are presented as key-value pairs, consisting of a tag key and a tag value. A single data point can have multiple tags attached.

Click the measurement name to view the corresponding tag list, which includes information such as the tag key, tag value statistics count, and description. The following operations are supported:

• Filter tags based on keywords in the search bar;
• Export the tag list as a CSV file.

Time Series¶

Time series are dynamically generated from tag combinations and include metrics, tags (fields), and data storage duration. Here, "metric + tag (field combination)" constitutes the primary key for data storage.

In Guance, this section displays the total number of time series for the current measurement and presents the number of unique values, time series count, and daily day-over-day change for a single metric/tag through metric statistics charts and tag statistics charts.

Storage Policy¶

The storage policy is divided into two levels:

• Workspace Global Settings: Applied to all measurements
• Measurement Custom Settings: Settings for specific measurements

Modifying Policy¶

The priority of custom settings for a measurement is higher than the workspace global settings. That is: After customizing the storage policy for a measurement, modifying the global settings will not affect that measurement.

Precautions¶

When modifying the storage policy for a measurement, pay attention to the following key rules:

1. Immediate data deletion: After modifying the policy, the data of this measurement under the original policy will be permanently deleted and cannot be recovered. Subsequent policy modifications will also delete the data under the current policy;
2. Independent storage mechanism: After customizing the policy, the measurement data is stored independently. Modifying the global policy duration at this point will not affect measurements that have been customized;
3. Reverting to global policy: When switching back to "Global Default", data will be stored back into the global repository. Subsequent modifications to the global policy will then affect this measurement;
4. Same duration does not mean same policy: Even if the custom duration is the same as the global one, the data is still stored independently. Example: When the global is 7 days, setting a measurement to 7 days still constitutes independent storage.

Modification Path¶

Global Settings¶

Go to Manage > Workspace Settings > Risky Operations > Change Data Storage Policy > Metrics, and select the storage duration.

Measurement Custom Settings¶

Go to Metrics > Metrics Management, and in the operation column on the right side of a single measurement, click the icon to select the duration. If not set, it automatically inherits the Global Policy.
