check_mount_exporter

check_mount Prometheus exporter

Check mount Prometheus exporter

The check_mount_exporter produces metrics about mount points mount status and if that mountpoint is read-only or read-write.

This exporter by default listens on port 9304 and all metrics are exposed via the /metrics endpoint.

Example of metrics exposed by this exporter:

check_mount_status{mountpoint="/",rw="rw"} 1
check_mount_status{mountpoint="/boot",rw="rw"} 1
check_mount_status{mountpoint="/opt",rw="rw"} 1
check_mount_status{mountpoint="/tmp",rw="rw"} 1
check_mount_status{mountpoint="/var",rw="rw"} 1

Usage

If the exporter is launched without --config.mountpoints then /etc/fstab will be parsed to identify which mountpoints to produce metrics for.

When parsing /etc/fstab you can exclude mountpoints using the --config.exclude.mountpoints and --config.exclude.fs-types flags.

The value for --config.mountpoints is comma separated while the exclude flags expect regular expressions.
