.TH "DISKMON" "1" "Sep 22, 2025" "6.9.0" "SeisComP"
.SH NAME
diskmon \- SeisComP Documentation
.sp
\fBMonitors a disk and sends notifications.\fP
.SH DESCRIPTION
.sp
Diskmon is a SeisComP init script that checks on each call to \fBseiscomp check\fP
the filesystem by running the following command:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
df | awk \-v max=\(dq%d\(dq \e\(aq{ if ( $5 > max ) print $0 }\e\(aq
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
where \(dq%d\(dq 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 \fBmail\fP command.
.sp
To make diskmon work it is important that \fBmail\fP is working on the shell.
.SH MODULE CONFIGURATION
