Alignak checks package for Windows passively checked hosts/services

Checks pack for monitoring Windows hosts with NSCA passive checks

Most recent PyPi version Join the chat #alignak on freenode.net License AGPL v3

Installation

The installation of this checks pack will copy some configuration files in the Alignak default configuration directory (eg. /usr/local/etc/alignak). The copied files are located in the default sub-directory used for the packs (eg. arbiter/packs).

From PyPI

To install the package from PyPI:

sudo pip install alignak-checks-windows-nsca

From source files

To install the package from the source files:

git clone https://github.com/Alignak-monitoring-contrib/alignak-checks-windows-nsca
cd alignak-checks-windows-nsca
sudo pip install .

Note: using `sudo python setup.py install` will not correctly manage the package configuration files! The recommended way is really to use `pip`;)

Documentation

Configuration

This checks pack do not need any specific configuration.

Prepare Windows host

Some operations are necessary on the Windows monitored hosts if NSClient++ is not yet installed and running.

Install and configure NSClient++ for scheduled NSCA checks.

The first example below is an NSClient configuration file and it schedules the NSCa checks with the default NSClient pre-installed commands (see alias). The second example is an NSClient registry configuration that defines its own commands in the NSCA scheduled checks. Anyway, for more information, we invite you to consult the NSClient ++ Web site.

NSClient++ Ini file configuration example:

CheckEventLog = 1
CheckExternalScripts = 1
CheckHelpers = 1
CheckNSCP = 1

Alignak configuration

You simply have to tag the concerned hosts with the template windows-passive-host.

define host{
    use                     windows-passive-host
    host_name               my_windows_passive_host
    address                 0.0.0.0
}

and this host will automatically inherit from the template parameters and services.
