Open Source Monitoring Tools

Open source monitoring projects

  • statsd is a node.js network daemon that listens for metrics and aggregates them for transfer into another service such as Graphite.
  • Graphite stores time-series data and displays them in graphs through a Django web application.
  • Bucky measures the performance of a web application from end user’s browsers and sends that data back to the server for collection.
  • Sensu is an open source monitoring framework written in Ruby but applicable to any programming language web application.
  • Graph Explorer by Vimeo is a Graphite-based dashboard with added features and a slick design.
  • PacketBeat sniffs protocol packets. Elasticsearch then allows developers to search the collected data and visualize what’s happening inside their web application using the Kibana user interface.
  • Munin is a client plugin-based monitoring system that sends monitoring traffic to the Munin node where the data can be analyzed and visualized. Note this project is written in Perl so Perl 5 must be installed on the node collecting the data.

  • Do you have remote access? Root access?
  • What evidence do you wish to collect from the system?
  • Remote acquisition of HDD, Ram or interactive query?
  • VM? Cloud? Local? Remote Office? Laptop? OS?
  • Custom tools? Audit scripts? Forensics Automation?
  • pslist, malfind, filescan, sockets, connscan, and connections with Volatility Framework?
  • Who’s talking to
  • Did you check your DNS logs?
  • Did you check your Firewall logs?
  • Did you check the outbound proxy?
  • Who’s internal address is on
  • What is that computer?
