  Default: -w 80 -c 90

  Check conntrack (net.netfilter.nf_conntrack_count) against thresholds. . Set to '' in order to disable this 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. . Set to '' in order to disable this check.

• 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

  Default: server

  Hostcheck to inherit

• hostgroups | string

  Comma separated list of hostgroups to add for these hosts

• lacp_bonds | string

  LACP bond interfaces, space-delimited (ie. 'bond0 bond1')

• load | string

  Default: auto
