## <a id="nscp-plugin-check-commands"></a> Plugin Check Commands for NSClient++
|
||||
|
||||
Icinga 2 can use the `nscp client` command to run arbitrary NSClient++ checks.
|
||||
There are two methods available for querying NSClient++:
|
||||
|
||||
* Query the [HTTP API](10-icinga-template-library.md#nscp-check-api) locally or remotely (requires a running NSClient++ service)
|
||||
* Run a [local CLI check](10-icinga-template-library.md#nscp-check-local) (does not require NSClient++ as a service)
|
||||
|
||||
Both methods have their advantages and disadvantages. One thing to
|
||||
note: If you rely on performance counter delta calculations such as
|
||||
CPU utilization, please use the HTTP API instead of the CLI sample call.
|
||||
|
||||
### <a id="nscp-check-api"></a> nscp_api
|
||||
|
||||
`check_nscp_api` is part of the Icinga 2 plugins. This plugin is available for
|
||||
both, Windows and Linux/Unix.
|
||||
|
||||
Verify that the ITL CheckCommand is included:
|
||||
|
||||
vim /etc/icinga2/icinga2.conf
|
||||
|
||||
include <plugins>
|
||||
|
||||
`check_nscp_api` runs queries against the NSClient++ API. Therefore NSClient++ needs to have
|
||||
the `webserver` module enabled, configured and loaded.
|
||||
|
||||
You can install the webserver using the following CLI commands:
|
||||
|
||||
./nscp.exe web install
|
||||
./nscp.exe web password — –set icinga
|
||||
|
||||
Now you can define specific [queries](https://docs.nsclient.org/reference/check/CheckHelpers.html#queries)
|
||||
and integrate them into Icinga 2.
|
||||
|
||||
The check plugin `check_nscp_api` can be integrated with the `nscp_api` CheckCommand object:
|
||||
|
||||
Custom attributes:
|
||||
|
||||
Name | Description
|
||||
:----------------------|:----------------------
|
||||
nscp\_api\_host | **Required**. NSCP API host address. Defaults to "$address$" if the host's `address` attribute is set, "$address6$" otherwise.
|
||||
nscp\_api\_port | **Optional**. NSCP API port. Defaults to `8443`.
|
||||
nscp\_api\_passwd | **Required**. NSCP API password. Please check the NSCP documentation for setup details.
|
||||
nscp\_api\_query | **Required**. NSCP API query endpoint. Refer to the NSCP documentation for possible values.
|
||||
nscp\_api\_arguments | **Optional**. NSCP API arguments dictionary either as single strings or key-value pairs using `=`. Refer to the NSCP documentation.
|
||||
|
||||
`nscp_api_arguments` can be used to pass required thresholds to the executed check. The example below
|
||||
checks the CPU utilization and specifies warning and critical thresholds.
|
||||
|
||||
```
|
||||
check_nscp_api --host 10.0.10.148 --password icinga --query check_cpu --arguments show-all warning='load>40' critical='load>30'
|
||||
check_cpu CRITICAL: critical(5m: 48%, 1m: 36%), 5s: 0% | 'total 5m'=48%;40;30 'total 1m'=36%;40;30 'total 5s'=0%;40;30

|
||||
|
||||
#### <a id="distributed-monitoring-windows-nscp-check-api"></a> NSCLient++ with check_nscp_api
|
||||
|
||||
The [Windows setup](6-distributed-monitoring.md#distributed-monitoring-setup-client-windows) already allows
|
||||
you to install the NSClient++ package. In addition to the Windows plugins you can
|
||||
use the [nscp_api command](10-icinga-template-library.md#nscp-check-api) provided by the Icinga Template Library (ITL).
|
||||
|
||||
The initial setup for the NSClient++ API and the required arguments
|
||||
is the described in the ITL chapter for the [nscp_api](10-icinga-template-library.md#nscp-check-api) CheckCommand.
|
||||
|
||||
Based on the [master with clients](6-distributed-monitoring.md#distributed-monitoring-master-clients)
|
||||
scenario we'll now add a local nscp check which queries the NSClient++ API to check the free disk space.
|
||||
|
||||
Define a host object called `icinga2-client2.localdomain` on the master. Add the `nscp_api_password`
|
||||
custom attribute and specify the drives to check.
|
||||
|
||||
[root@icinga2-master1.localdomain /]# cd /etc/icinga2/zones.d/master
|
||||
[root@icinga2-master1.localdomain /etc/icinga2/zones.d/master]# vim hosts.conf
|
||||
|
||||
object Host "icinga2-client1.localdomain" {
|
||||
check_command = "hostalive"
|
||||
address = "192.168.56.111"
|
||||
vars.client_endpoint = name //follows the convention that host name == endpoint name
|
||||
vars.os_type = "Windows"
|
||||
vars.nscp_api_password = "icinga"
|
||||
vars.drives = [ "C:", "D:" ]
|
||||
}
|
||||
|
||||
The service checks are generated using an [apply for](3-monitoring-basics.md#using-apply-for)
|
||||
rule based on `host.vars.drives`:
|
||||
|
||||
[root@icinga2-master1.localdomain /etc/icinga2/zones.d/master]# vim services.conf
|
||||
|
||||
apply Service for "nscp-api-" (drive in host.vars.drives) {
|
||||
import "generic-service"
|
||||
|
||||
check_command = "nscp_api"
|
||||
command_endpoint = host.vars.client_endpoint
|
||||
|
||||
//display_name = "nscp-drive-" + drive
|
||||
|
||||
vars.nscp_api_host = "localhost"
|
||||
vars.nscp_api_query = "check_drivesize"
|
||||
vars.nscp_api_password = host.vars.nscp_api_password
|
||||
vars.nscp_api_arguments = [ "drive=" + drive ]
|
||||
|
||||
ignore where host.vars.os_type != "Windows"
|
||||
}
|
||||
|
||||
Validate the configuration and restart Icinga 2.
|
||||
|
||||
[root@icinga2-master1.localdomain /]# icinga2 daemon -C
|
||||
[root@icinga2-master1.localdomain /]# systemctl restart icinga2
|
||||
|
||||
Two new services ("nscp-drive-D:" and "nscp-drive-C:") will be visible in Icinga Web 2.
|
||||
|
||||
|
||||
|
||||
Note: You can also omit the `command_endpoint` configuration to execute
|
||||
the command on the master. This also requires a different value for `nscp_api_host`
|
||||
which defaults to `host.address`.
|
||||
|
||||
//command_endpoint = host.vars.client_endpoint
|
||||
|
||||
//vars.nscp_api_host = "localhost"
|
||||
|
||||
You can verify the check execution by looking at the `Check Source` attribute
|
||||
in Icinga Web 2 or the REST API.
