Enable metrics logging

This chapter describes how to enable the metrics that you want to monitor.

A subset of all available metrics is enabled by default. See metrics.filter. The list was last updated in version 4.2.

You can enable/disable metrics using the configuration setting metrics.enabled. You can also use the setting metrics.filter to enable only the metrics that you want. The metrics must be specified as a comma-separated list of globbing patterns. The following example enables all checkpoint metrics and the pagecache eviction metric:

# Setting for enabling all supported metrics. (Default is true) Setting this to false disables all metrics.

# Setting for exposing metrics.

When specifying a complete metric name, you should take into account whether metrics.namespaces.enabled is set.

All metrics are logged to CSV files in the /metrics folder.
