|Ganglia||Fix error in inclusion/exclusion checking|
|gang2graph.pl||Make default exclude nothing|

USAGE This pulls the XML file from gmetad (localhost:8651 by default) and pumps it into Graphite (localhost:2023 the carbon-aggregator port by default). I run it as a minutely cronjob: * * * * * root cd /home/web/gang2graph; perl gang2graph.pl With 160 hosts and 38,000 metrics the elapsed time is less than 3 seconds on a 4100 series AMD Opteron, but it is hobbled by Graphite's disk writing. For this reason, gang2graph support specify a set of hosts to send to Graphite, ignoring the rest. Simply set the $host variable in gang2graph.pl to a set of hosts to copy and only those will be copied. The checking is a regex, so subsets of hostnames works. To copy metrics from this set of hosts: apb00.clearspring.com apb01.clearspring.com apw00.clearspring.com apw01.clearspring.com but exclude apm*, adm*, etc. I use this $hosts: ['apb', 'apw'] Feel free to email me with questions.
