Discard metrics to avoid resource waste - Managed Service for Prometheus

This topic describes how to view the amount of reported metric data to evaluate the efficiency of data collection and the monitoring scope, and discard useless metrics to prevent resource waste.

Prerequisites

A Prometheus instance is created. For more information, see the following topics:

Note

The metrics of a general-purpose Prometheus instance can be viewed and cannot be discarded. You can click Metric Management in the left-side navigation pane of the instance details page to view the metric details.

View metrics

Log on to the Managed Service for Prometheus console.
In the left-side navigation pane, click Instances.
Click the name of the Prometheus instance.

In the left-side navigation pane, click Service Discovery. On the Metrics tab, you can view parameters, such as Metric Name, Job Name, Metric Type, Proportion, and Metric Quantity in Last 10 Minutes.

You can query metrics by job name or metric type. You can also enter a keyword in the search box to perform fuzzy matching.

Parameter	Description
Metric Name	The name of the metric.
Job Name	The name of the job that collects the metric.
Metric Type	Basic Metrics Custom Metrics
Proportion	The percentage of data reported for the metric in the total number of metric data.
Metric Quantity in Last 10 Minutes	The number of data reported for the metric and stored in the last 10 minutes.

If you no longer want your Prometheus instance to monitor some metrics, you can discard these metrics. You are not charged for discarded metrics.
