alignak_module_nsca 2.0.0

Installation

The installation of this module 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 modules (eg. arbiter/modules).

Short description

This module for Alignak receiver reads and decodes NSCA passive notifications to dispatch them into the Alignak framework.

Features / Known limitations

Handles NSCA version 3 protocol

Check the NSCA packet timestamp for staled data (older than a certain amount of time) or ‘future’ data (future timestamp).

Consider the host_check service received data as a passive host check. Useful if your NSCA client does not handle correctly the passive host check syntax ;)

The NSCA module implementation is currently limited to the “xor” obfuscation/encryption.

Configuration

Once installed, this module has its own configuration file in the /usr/local/share/alignak/etc/alignak.d directory. The default configuration file is alignak-module-nsca.ini. This file is commented to help configure all the parameters.

The default configuration is convenient for ‘recent’ NSCA client implementing NSCA version 3.

This configuration has been tested with Linux send_nsca 2.9.1 and Windows NSClient most recent versions (from 0.4.1).

To configure Alignak receiver to use this module:

• edit your receiver daemon configuration file

• add the module_alias parameter value (nsca) to the modules parameter of the daemon

To set up several NSCA listeners:

• copy the default configuration to another file,

• change the module alias parameter (nsca_bis)

• change the listening port

• edit your receiver daemon configuration file

• add the new module_alias parameter value (nsca_bis) to the modules parameter of the daemon
