Service Monitor - Version 1.3!

A command line toolkit written in Python for monitoring for external systems

Dependencies

Make sure you have these Python modules installed by running pip install -r requirements.txt

• matplotlib - For plotting, of course
• paramiko - For ssh connections

These libraries are also used, but should already be included in your Python installation:

• os
• re
• time
• sys
• datetime
• smtplib
• configparser
• requests (Included in requirements.txt for MacOS builds of python)

Configuration and Setup

Take a look at cfg/example_cfg.ini and create your own cfg.ini file in the same directory with matching fields.

Currently, there are two options that change the behaiviour of the entire toolkit:

• graphs Show graphical data
  
• verbose Print data to console in real time with severity (recommended)
  
  

Other configuration options are commented in the example file.

Scripts

Script 1: pingMonitor.py [FUNCTIONING]

Indefinitely pings domains/hosts within the domains_list in config and graphs the ping for each domain in real time. Upon a missing response, a notification email is sent. Emails, graphs and console outputs can be configured.

Script 2: resourceMonitor.py [FUNCTIONING]

Using the paramiko library to ssh and run resource monitoring commands on a host. This script goes on to graph the CPU and RAM usage in real time for the chosen host.

Script 3: websiteMonitor.py [FUNCTIONING]

Using the requests library, this script will check that the configured domains/hosts are serving some html content. Similar to pingMonitor, but will check for a web page response, as opposed to a ping from the name server. Has a configurable time for over what time period a downtime email should be repeated. Will also send a "Back up and running" email after detected downtime.

Roadmap

• Enable specification of intervals in /cfg/cfg.ini
• Looking at monitoring the run queue of a host
• Open to suggestions!
