Nagios Plugin Configuration
|
|
===========================
|
|
|
|
Configure Access to Nagios
|
|
--------------------------
|
|
|
|
The following should be set in **/etc/vitrage/vitrage.conf**, under synchronizer_plugins section:
|
|
|
|
+----------------------+------------------------------------+--------------------------------+
|
|
| Name | Description | Default Value |
|
|
+======================+====================================+================================+
|
|
| nagios_user | Nagios user | |
|
|
+----------------------+------------------------------------+--------------------------------+
|
|
| nagios_password | Nagios password | |
|
|
+----------------------+------------------------------------+--------------------------------+
|
|
| nagios_url | Nagios url for querying the data | |
|
|
+----------------------+------------------------------------+--------------------------------+
|
|
| nagios_config_file | Nagios configuration file | /etc/vitrage/nagios_conf.yaml |
|
|
+----------------------+------------------------------------+--------------------------------+
|
|
|
|
**Example**
|
|
|
|
nagios_user = nagios
|
|
|
|
nagios_password = nagios
|
|
|
|
nagios_url = http://10.20.30.40/monitoring/nagios/cgi-bin/status.cgi
|
|
|
|
nagios_config_file = /etc/vitrage/nagios_conf.yaml
|
|
|
|
|
|
Configure Nagios Host Mapping
|
|
-----------------------------
|
|
|
|
Nagios tests are defined in a table with columns: Host, Service, Status, Last Check, etc.
|
|
|
|
Nagios "Host" is not necessarily a resource of type host. It can also be an instance, switch, or other resource types. **nagios_conf.yaml** is used to map Nagios host type to a Vitrage resource.
|
|
|
|
**Format**
|
|
::
|
|
|
|
nagios:
|
|
- nagios_host: <Host as appears in Nagios>
|
|
type: <resource type in Vitrage>
|
|
name: <resource name in Vitrage>
|
|
|
|
- nagios_host: <Host as appears in Nagios>
|
|
type: <resource type in Vitrage>
|
|
name: <resource name in Vitrage>
|
|
|
|
...
|
|
|
|
|
|
**Example**
|
|
|
|
The following file will map compute-1 to a nova.host named compute-1; and compute-2 to a nova.host named host2
|
|
|
|
::
|
|
|
|
nagios:
|
|
- nagios_host: compute-1
|
|
type: nova.host
|
|
name: compute-1
|
|
|
|
- nagios_host: compute-2
|
|
type: nova.host
|
|
name: host2
|
|
|
|
|
|
|
|
**Default Configuration**
|
|
|
|
A default nagios_conf.yaml will be installed with Vitrage. Its content is still TBD, but it will be similar to the following example.
|
|
|
|
All Nagios hosts named host* or * -devstack will be mapped in Vitrage to resoruces of type nova.host with the same name; and all Nagios hosts named instance* will be mapped to nova.instance resources.
|
|
|
|
::
|
|
|
|
nagios:
|
|
- nagios_host: host-(.*)
|
|
type: nova.host
|
|
name: ${nagios_host}
|
|
|
|
- nagios_host: (.*)-devstack
|
|
type: nova.host
|
|
name: ${nagios_host}
|
|
|
|
- nagios_host: instance-(.*)
|
|
type: nova.instance
|
|
name: ${nagios_host}
|
