SHOW DIAGNOSTICS statement

Diagnostic information includes mostly information about your InfluxDB server that is not necessarily numerical in format. This diagnostic information is not stored in the _internal database.

To see InfluxDB server or node diagnostic information, you can use the SHOW DIAGNOSTICS statement. This statement returns InfluxDB instance information, including build details, uptime, hostname, server configuration, memory usage, and Go runtime diagnostics. This information is particularly useful to InfluxData Support, so be sure to include the output of this query anytime you file a support ticket or GitHub issue.
