Jlewis Johnlewis Nrpe

conntrack | string

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

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

lacp_bonds | string

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

load | string

Default: auto

Load check arguments (e.g. "-w 8,8,8 -c 15,15,15"); if 'auto' is set, thresholds will be set to multipliers of processor count for 1m, 5m and 15m thresholds, with warning as "(4, 2, 1)", and critical set to "(8, 4, 2)". So if you have two processors, you'd get thresholds of "-w 8,4,2 -c 16,8,4". . Set to '' in order to disable this check.

mem | string

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

Check memory % used. By default, thresholds are applied to the non-hugepages portion of the memory. . Set to '' in order to disable this check.

monitors | string

Additional monitors defined in the monitors yaml format (see README)

nagios_address_type | string

Default: private

Determines whether the nagios host check should use the private or public IP address of an instance. Can be "private" or "public".

nagios_host_context | string

Default: juju

A string which 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

Default: unit

Determines whether a server is identified by its unit name or host name. If you're in a virtual environment, "unit" is probably best. If you're using MaaS, you may prefer "host".

nagios_master | string

Default: None

IP address of the nagios master from which to allow rsync access

netlinks | string

Network interfaces to monitor for correct link state, MTU size and speed negotiated. Parsed keywords are mtu, speed, op. Other keywords are ignored. . For example (multi-line starts with pipe): - eth0 mtu:9000 speed:25000 - lo mtu:65536 op:unknown - br0-mgmt mtu:9000 - br0-sta mtu:9000 - br0-stc mtu:9000 - br0-api mtu:1500 - bond0 mtu:9000 speed:50000 - bond0.25 mtu:1500 speed:50000 - ens3 mtu:1500 speed:-1 desc:openstack_iface - ...

procs | string

Set thresholds for number of running processes. Defaults to disabled; to enable, specify 'auto' for the charm to generate thresholds based on processor count, or manually provide arguments for check_procs, for example: "-k -w 250 -c 300" to set warning and critical levels manually and exclude kernel threads.

ro_filesystem_excludes | string

Default: /snap/,/sys/fs/cgroup

Comma separated list of mount points to exclude from checks for readonly filesystem. Can be a substring rather than the entire mount point, e.g. /sys will match all filesystems beginning with the string /sys. The check is disabled on all LXD units, and also for non-container units if this parameter is set to ''.

server_port | int

Default: 5666

Port on which nagios-nrpe-server will listen

sub_postfix | string

A string to be appended onto all the nrpe checks created by this charm to avoid potential clashes with existing checks

swap | string

Default: -w 40% -c 25%

Check swap utilisation. See the nagios check_swap plugin help for further details. . Set to '' in order to disable this check.

swap_activity | string

Default: -i 5 -w 10240 -c 40960

Swapout activity check. Thresholds are expressed in kB, interval in seconds. . Set to '' in order to disable this check.

users | string

Set thresholds for number of logged-in users. Defaults to disabled; to enable, manually provide arguments for check_user, for example: "-w 20 -c 25"

xfs_errors | string

dmesg history length to check for xfs errors, in minutes . Defaults to disabled, set the time to enable.

zombies | string

Zombie processes check; defaults to disabled. To enable, set the desired check_procs arguments pertaining to zombies, for example: "-w 3 -c 6 -s Z"
