Nagios Scraper

Purpose:

If you are running multiple Nagios sessions in your browser, you need to constantly check in with them. If authentication is turned on, sometimes you have to re-login to them. This script is built to give ONE console of information from ALL your Nagios sources through the command line.

Installation:

• Clone this repo into a directory.
• Copy scraper.py.example to scraper.py
• Edit scraper.py to add the parameters to your install:
  • Keep the existing structure. It is pure-Python that gets imported
  • First key is the URL, without the trailing slash (i.e. 'http://192.168.0.5/nagios':)
  • Each key has 3 required parameters:
    • user is the user that can log in to Nagios
    • password is their password
    • auth_type is either Basic or Digest. If one doesn't work, try the other.
  • You can have as many keys as you want, as long as the three parameters are specified
• Ensure you have python3 installed (untested with Python2, which is EOL anyways)
• Ensure you have pip3 installed to install the dependencies:
  • tabulate
  • bs4 (BeautifulSoup)
• Run python3 -m pip install -r requirements.txt to auto-install the required libraries
• Run python3 nagios-scraper.py

If you mess up the configuration, copy the example file back over the official .conf file, and start again.

Output:

A table showing your Nagios instances, and the status of the hosts and services. Assuming the config file is updated with correct information, you will see something like this:
