Well at least since version 3.3.1. Before that, we have been changing setup's so I don't know. Cheers, - Ramon.

Thanks, Bernard On Tuesday, June 19, 2012, Ramon Bastiaans wrote: Hi Bernard, This collector daemon gathers metrics from 512 machines. Every node has ~100 metrics, this results in ~50.000 metrics. I do realize this is a somewhat large amount of metrics for 1 gmond and that this can require a lot of memory. Nevertheless I would expect the memory usage to level out at a certain point. We only use modpython on this machine. When I disable the modpython module and move all *pyconf*, the memory usage still climbs over time. I made a little script to print the amount of HOST/METRICs in memory every minute and the memory consumption of gmond. It seems whever there is a (temporary, small) decrease in METRICs in the gmond's XML, the next cycle the memory usage increases. This sounds like something is not free'd / cleaned. See the attached log. Cheers, - Ramon. On 18-6-2012 17:22, Bernard Li wrote: Hi Ramon: That's not good... are you by chance running any metric modules? How many nodes report to this collector? What if you turn off all except for one gmond reporting to it, does it still leak memory?

At one of our systems the "collector" gmond reaches up to 2GB memory if we keep it running long enough, see attached graph. I'm no expert but when I run "valgrind" on gmond for a few minutes, amongst other things, it says: ==17668== LEAK SUMMARY: ==17668== definitely lost: 22,339 bytes in 50 blocks ==17668== indirectly lost: 2,206,722 bytes in 659 blocks ==17668== possibly lost: 0 bytes in 0 blocks ==17668== still reachable: 154,605 bytes in 2,745 blocks ==17668== suppressed: 0 bytes in 0 blocks ==17668== Reachable blocks (those to which a pointer was found) are not shown. ==17668== To see them, rerun with: --leak-check=full --show-reachable=yes I'm not sure how accurate or correct this is, but is anyone aware of memory usage issues?
