Editing the MQL Expression for a Query

Directly edit the MQL expression used to query metric data in Monitoring.

For an example MQL expression, see Example Query and Metric Chart. For information about all query elements, including compartment and metric namespace, see Creating a Query. For troubleshooting, see Troubleshooting Monitoring or Troubleshooting Queries.

This section describes how to edit the MQL expression on the Metrics Explorer page. The MQL expression is available in Advanced mode only. For alarm query edits, see Creating a Basic Alarm.
