Learn about configurations >

• conntrack | string

  Default: -w 80 -c 90

  conntrack table check

• debug | boolean

  Setting debug to True enables debug=1 in nrpe.cfg

• disk_root | string

  Default: -u GB -w 25% -c 20% -K 5%

  Root disk check. This can be made to also check non-root disk systems as follows: -u GB -w 20% -c 15% -r '/srv/juju/vol-' -C -u GB -w 25% -c 20% The string '-p /' will be appended to this check, so you must finish the string taking that into account. See the nagios check_disk plugin help for further details.

• dont_blame_nrpe | boolean

  Setting dont_blame_nrpe to True sets dont_blame_nrpe=1 in nrpe.cfg This config option which allows specifying arguments to nrpe scripts. This can be a security risk so it is disabled by default. Nrpe is compiled with --enable-command-args option by default, which this option enables.

• export_nagios_definitions | boolean

  If True nagios check definitions are written to '/var/lib/nagios/export' and rync is configured to allow nagios_master to collect them. Useful when Nagios is outside of the juju environment

• hostcheck_inherit | string

  Default: server

  Hostcheck to inherit

• hostgroups | string

  Comma separated list of hostgroups to add for these hosts

• load | string

  Default: auto

  Load check arguments (e.g. "-w 8,8,8 -c 15,15,15"); if 'auto' is set, then NUM_CPUS*0.7 is used for the warning threshold and NUM_CPUS for critical.
