conntrack | string

Default: -w 80 -c 90

conntrack table check

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.

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 (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 the critical one

mem | string

Default: -C -u -w 85 -c 90

Memory check

monitors | string

nagios_host_context | string

Default: juju

a string that will be prepended to instance name to set the host name in nagios. So for instance the hostname would be something like: juju-postgresql-0 If you're running multiple environments with the same services in them this allows you to differentiate between them.

nagios_hostname_type | string
