Monitoring with Opsview, based on Nagios

Opsview is a nice wrapped installation, based on Nagios – one of the biggest open source monitoring systems.

Opsview is delivered in two different versions. One “Community version” -free as in Beer. ONe “Enterprise version” -not so much free, but with a support contract and officially supported from Opsera.dert i prisen.

We have installed opsview for several customers, with good results

  • Basis-install is quick, more or less ‘yum install opsview’ and a web-gui for everything else.
  • You need a server, prefferably a physical Linux-server. Virtual might work on small scale installations, more hardware needed for medium size. For large scale you migh want to look at plain nagios, as Opsview really does not scale very well. (See below)
  • Integrates with SMS-services online, or dedicated GSM-phone.
  • All Nagios-plugins will work with Opsview
  • Nagios-plugins exists for most hardware and software on te marked. Special tests can easily be created using almost any scripting or programming language.
  • All management is done from the web-interface, which is quite easy to understand, although a bit slow.


  • Etter fleire installasjoner, og breiere erfaring, viser det seg at for større installasjoner skalerer ikkje opsview godt nok i standard utgave.
  • After several installations, and more experience, opsview does not scale well in a large environment.
  • More than 500 hosts and approx. 5000 tests will kill a reasonably good server (Dell R710, 2 CPU, 12GB RAM, 2 SAS 15K disks in Raid 1) Plain nagios on the other hand, will easily scale to at least 4 times this on the same server.
  • For a smaller environment, the advantages of a good GUI will outweigh the scaling issues, while a large environment needs to look at other options.
  • Lately more clones has been released, and I will absolutely have a look at Icinga when I have the time
