Munin wish list

Put your wishes here. (The ticket base can also be used as a wishlist).

In the process of implementation:

Patches available but not integrated:

  • GUI to create agregated graphs - DONE - see attachment muninAggregator.pl
  • Zoomable graphs, patch is waiting in #6 to be integrated
  • Tabbed graph pages
  • Graph Colours ala Edward Tufte (email)
  • Other Native Transports. Makes direct SSH data-gathering without using an SSH-tunnel/Inetd trampoline possible. Might evolve later to also support HTTP/CGI data-gathering.

Wished features in no particular order:

  • GUI to create percentage-from-numbers graphs
  • GUI to create custom "frankenstein" pages by picking graphs from other places
  • Dashboard showing "interesting things". Currently we are a quite simple hack away from a dashboard showing graphs with warning or critical status. Other interesting graphs could be: Steep inclines or declines. RRD based anomalty detection.
  • graphs of a particual category should be grouped in one html file (i. e. one html file for all graphs in the network category, one for all graphs in the apache group, ...) - see the above aggregated graph tool
  • Plugin console on the central node - makes munin-node enable and disable plugins and control wildcard plugin params (requires protocol extentions, and probably authentication to safely. A really cool console would allow uploading of plugins to the nodes.
  • Munin should be able to output the current value as plain text outside the graph for easy screen-scraping of munin values. Useful when you want to automatically monitor machines you do not have root access to, or you cannot speak with munin-node directly, but are only able to see the munin graphs webpage.
  • Implement offline mode (munin should request data from the last time it successfully received any otherwise if there are significant downtime periods gaps will appear on the graphs) -- This is planned for 1.4
  • To have help or documentation in context of the graphs (clickable at the very graph). Using munin for maintainance people would be much easier if concise information is available about what those graphs really mean. Expecting those people to read perl scripts to understand the working is not an option. Half done: We have "munin-doc" but you have to log into the node with the plugin to be sure it's the right doc.
  • Custom graph date scale. Currently graph's x-scales are limited to day, week, month and year. Custom ranges like 3, 6 months or even longer ranges like 5 years fit better for some applications. Zoomable graphs (see above) would help as well for this requirement.
  • Solaris/indiana packages or instructions
  • instructions (or scripts) on how to rename hosts properly
  • '<pluginname>.update no' in the munin.conf should also mean: do not draw the graph, because it is empty
  • Support the TICK linetype present in rrdtool, for marking points or on/off states.
  • merge features of mysqlard into the mysql plugins
  • add support to optimize png via optipng to reduce traffic.
