Munin

Munin the monitoring tool surveys all your computers and remembers what it saw. It presents all the information in graphs through a web interface. Its emphasis is on plug and play capabilities. After completing a installation a high number of monitoring plugins will be playing with no more effort. Additional plugins can be easily developed and contributed. See the Plugin Gallery for a wide range of more than a thousand community supported plugins. By sending us patches, you automatically license the code under the same terms as Munin. We also might edit your commits metadata (the comment part) for clarifications, but we'll leave the diff part intact (except for whitespace edits). So in case there's a problem with the commit diff, we either commit another patch thereafter or plainly ask you to rework it. We might eventually squash some of your commits into one. Please always rebase your pull requests on a released version tag, one of the stable branches, or the default branch, master . If you request a pull against master , your pull will be automatically closed upon merge. If you request against one of the stable release branches, your pull will be automatically closed upon the next release. Information on developing Munin with GitHub, such as how branches are used and the version numbering scheme, can be found in Munin's GitHub Wiki .
