=head1 NAME
|
||
|
|
|
||
|
|
services - Plugin to monitor number of processes of different services
|
||
|
|
|
||
|
|
=head1 CONFIGURATION
|
||
|
|
|
||
|
|
This plugin uses the following configuration variables
|
||
|
|
|
||
|
|
[services]
|
||
|
|
env.datafile - Path to file which contains list of services (default: /root/munin/services.list)
|
||
|
|
|
||
|
|
Datafile should contain lines which are used to detect number of running processes (ps ax | grep "LINE FROM FILE").
|
||
|
|
If a number of processes of some service is below 1 (e.g. 0) critical event happens (configure your munin.conf about "contact.NAME.command" to send mail or something else;
|
||
|
|
also nice line is 'contact.NAME.always_send critical' - not to stop sending alerts after critical event appears the first time).
|
||
|
|
|
||
|
|
Datafile may contain comment lines (begin with "#"), empty lines and even regular expressions (WARNING - not tested, use carefully)
|
||
|
|
Example of datafile:
|
||
|
|
#############################
|
||
|
|
# This line is a comment and next lines are names of some services
|
||
|
|
sshd
|
||
|
|
smbd
|
||
|
|
nmbd
|
||
|
|
lighttpd
|
||
|
|
# Next line is an empty line
|
||
|
|
|
||
|
|
named
|
||
|
|
# Next line is a name of service with a path
|
||
|
|
/usr/local/sbin/upsd
|
||
|
|
# Next line is a line with spaces
|
||
|
|
BackupPC -d

This plugin does not draw any graphs. It is only written to send alerts via mail or something else.
