Hi,
I have some performance troubles with the poller, it takes a bit more than 5 minutes to finish. There are 128 devices to poll...
Looking at the "Performance tuning" wiki page and the mailing list, I implemented the following tweaks: * Using poller-wrapper from Job Snijders ("Multiple poller instances" was really bad, polling took about 10 minutes) * Activated RRDcached
Putting the RRDs on a Ramdisk is not a solution for me (too less memory). Does memcache work with the current SVN build? What other options for performance tuning do I have? One idea was to have "worker" server which only poll a subset of devices and report the values back to the master. Is something like that possible? Which resources need the most I/O? RRD or MySQL? Are there many inserts and updates to the Database?
Thanks for all suggestions...
Cheers, Tobias
