Nagios Mass-Scheduler

Introduction

nagios-mass-scheduler is a small Python Flask application to make scheduling or acknowledging of multiple services easier. It can accept an author, comment and optional downtime (expressed as a target time, not a number of seconds).

Installation

1. Copy the source to somewhere convenient, for example /srv/mass-scheduler
2. Install the Python dependencies listed in requirements.txt
3. Use npm to install JavaScript dependencies: cd static && npm install
4. Configure the Nagios .dat plugin file and output FIFO queue file locations in settings.ini

Connecting the web server

An excercise for the reader. For Apache, mod_wsgi3 is recommended with the following example configuration:

WSGIDaemonProcess mass-scheduler python-path=/srv/mass-scheduler user=www-data group=www-data threads=5
WSGIScriptAlias /mass-scheduler /srv/mass-scheduler/wsgi.py
WSGIScriptReloading On
<Directory /srv/mass-scheduler>
    WSGIProcessGroup mass-scheduler
    WSGIApplicationGroup %{GLOBAL}
    AllowOverride none
</Directory>

Permissions

Whichever user runs nagios-mass-scheduler will need to be able to read the status file and write to the command file.
