|
||
|
||
#### Automatically enable some probes
|
||
|
||
It can be useful to automatically enable some probes according to the type of
|
||
servers :
|
||
* Enable temp probe on hardware hosts (also useful for Smartoverall and Smart):
|
||
|
||
``` yml
|
||
xymon_cli__plug_temp_state: '{{ True
|
||
if (ansible_virtualization_role == "host")
|
||
else False }}'
|
||
```
|
||
|

``` yml
|
||
- hosts: serverXYZ
|
||
roles:
|
||
- role: ipr-cnrs.xymon
|
||
```
|
||
|
||
## Configuration
|
||
|
||
This role will :
|
||
* Install needed packages to provide `xymon-client`.
|
||
* Manage `xymon-client` configuration and service.
|
||
* Add 'xymon' user to new groups.
|
||
|
||
## Plugins
|
||
|
||
Some plugins and options can be managed with this role :
|
||
* apt : Check state of packages and repositories.
|
||
* libs : Check for running processes with upgraded libraries.
|
||
* mq : Check mail queue.
|
||
* zfs : Check ZFS pools status.
|
||
|
||
## Development
|
||
|
||
This source code comes from our [Gogs instance][xymon source] and the [Github repo][xymon github] exist just to be able to send the role to Ansible Galaxy…
|
||
|
||
But feel free to send issue/PR here :)
|
||
|
||
Thanks to this [hook][gogs to github hook], Github automatically got updates from our [Gogs instance][xymon source] :)
