What's new in Munin 2.0 Alpha 2:

January 20th, 2011

Summary :
· Huge performance boost
· munin-graph is over, cgi graphing only from now on
· Enabling CGI HTML with an reworked UI
· use a binary DB to store spoolfetch timestamps (fixes growing file bug in 2.0a1)
· documentation cleanup

Enhancements :
· Better node side timeout error message allowing things to be found out if needed
· Properly label the bgbouncer queries-per-second graph.
· Properly return undef when the SNMP client returns noSuchObject instead of setting an error.
· munin-node: Insert a reset_timeout() call to enable the master to get in a word in edgeways after a slow plugin has executed
· munin-html: Start using fork to save some wall-clock time. Option --fork us now active and max_html_jobs is recognized by munin-html as the maximum number of paralell processes.
· Actually recognize max_html_jobs as a config parameter
· Add the publication part
· Clean up Perl warnings due to use of undefined variables in two functions in LimitsOld.pm.
· looking at the Net::SNMP doco, -username cannot be '' (it must be between 1 and 32 characters).
· The time of munin-graph is over, cgi from now on
· since pollers are now being respawned if they fall over, the shutdown-spooler signal handlers need to be removed before starting any poller up.
Cleanup of munin-cgi-graph:
· Make it log right
· Make it fast (now

· pgsql: Properly apply filters to config query as well for wildcard plugins,
· so we don't generate lots of nan fields in the graphs.
· munin-html: Do not try to calculate png size, use geometry of the file
