# diskmon — SeisComP Release documentation

6.9.0

# diskmon

Monitors a disk and sends notifications.

## Description

Diskmon is a SeisComP init script that checks on each call to seiscomp check the filesystem by running the following command:

    df | awk -v max="%d" \'{ if ( $5 > max ) print $0 }\'

where “%d” is replaced by the configured threshold. If there are lines in the output (which means some filesystem exceed the usage threshold) it sends the output along with a description line to all configured receipients using the mail command.

To make diskmon work it is important that mail is working on the shell.

## Module Configuration

Note

diskmon is a standalone module and does not inherit global options.

`etc/defaults/diskmon.cfg`
`etc/diskmon.cfg`
`~/.seiscomp/diskmon.cfg`

threshold

  Comma-separated list of e-mail addresses to notify when disk usage threshold is exceeded.
