Observium is an autodiscovering SNMP based network monitoring platform written in PHP which includes support for a wide range of network hardware and operating systems including Cisco, Windows, Linux, HP, Dell, FreeBSD, Juniper, Brocade, Netscaler, NetApp and many more.

Observium has grown out of a lack of network monitoring platforms which are both simple to manage and pleasant to use. It is intended to provide a navigable interface to the health and performance of your network. Its design goals include collecting as much historical data about devices as possible, using as much auto-discovery as possible with little or no manual intervention, and having a very intuitive interface.

Observium is not intended to replace an up/down alerting system like Icinga or Nagios, but rather to complement it with an easy to manage, intuitive representation of historical and current performance statistics, configuration visualisation and syslog capture.

Observium is available in 2 different flavours: Observium Professional which is distributed via an SVN-based release mechanism, providing rapid access to security and bug fixes as well as new features. This includes automated database schema upgrades. Updates can be performed automatically via cron or manually. Observium Community Edition is distributed via 6-monthly .tar.gz releases under a modified QPL Open Source license. The most recent release is 0.14.4p1 (6th April 2014) based on SVN revision 5229.

A condensed Changelog is provided each month detailing the improvements to the Professional/Subscription version.

The condensed change log for October is now available at Changelog.

23rd July 2013

We're pleased to announce that we've reached a development milestone on the road to replacing all of our hated monitoring applications.

The last 2 weeks spent in Amsterdam collaborating on the alerting system have been immensely productive, thanks to the great visionaries Maarten Moerman of eBay and Job Snijders of Atrato, we would like to thank them for their continuous support, Coke Zero and Appelkoeks.

The fundamental schema for the alerting system have been defined and a basic working framework written. This week will be spent further improving and bug-fixing the framework so that we can move on to writing a UI to easily change the alert rule sets and associations.

29th May 2013

The Kickstarter campaign was a great success. We achieved 200% of our goal. Thanks to everyone who contributed!

25th April 2013

We've launched a Kickstarter campaign to fund the addition of threshold and up/down alerting to Observium.

Update - Within 15 minutes of going live the entire campaign was generously funded by Dutch ISP Atrato IP Networks. We thank them for their generosity!


8th April 2013

We've almost finished implementing the new Bootstrap-based UI. We're still migrating a few UI elements and modifying Bootstrap to more closely fit our use-case, but overall the improvement is dramatic.

For the future we have support planned for more enterprise-class equipment, such as Netscaler and NetApp, and improving support for tracking VMs.

We recently added a new developer, Mike Stupalov (landy). Thus far he has mostly been focusing on improving the quality of Observium's code-base and implementing bug fixes.

31st January 2013

We've replaced the old front page with a new, more easily customisable front page. You can find out how to customize it on on the Configuration Options page.

29th November 2012

Adam is currently on an extended vacation in Mexico recovering from an operation and working on adding support for new devices and features and trying to clean up some old bits of the UI when the heat permits. We've added a lot of new things since April, most notably support for Netscaler load balancers, tracking Vservers and Services.

24th April 2012

We released version a few days ago, and we hope you enjoy it! We have switched to Subversion-release only, no more .tar.gz files. Some extra documentation was added to the wiki to explain this and assist you in using it, see Using SVN to find out more about our Subversion releases. We've received quite some interesting patches through our bugtracker, mailing list and IRC channel alike and applied most of them, thanks to all contributors! Some of them are already in the aforementioned release, others are in current trunk and will be in a later release. Don't hesitate to post your suggestions or bugs in our Jira bug tracker - do use common sense first, and reports with patches are obviously most appreciated!

2nd April 2012

To better concentrate our support efforts, we have switched from Flyspray to Jira. Unfortunately there is no automatic importer, so we'll be going over the open issues in Flyspray to see if anything needs to be recreated in Jira. The forum will also not be used anymore. For support questions, please use the mailing list and/or the IRC channel. We'll try to keep the documentation on the website up to date so please consult the Documentation and the FAQs first before consulting the mailing list.
