Maciej,
can you post top 100 lines or so of your config ie. with all the udp channels etc. Thanks On 02/07/2014 08:52 AM, Maciej Lasyk wrote: Hi guys, I've been struggling with very high cpu usage of my gmond daemons lately. I've been using UDP unicast topology. I just couldn't find the source of my problem. All my gmonds on my servers were generating ~99-100% of procs usage.stracing gmond processes revealed zounds of epools and gettimeofdays syscalls (like very many every second) and that was all. I tried to start from scratch - there was no problem when using default config (mutlicast topo, deaf/mute=no). So after playing a while I thought that _maybe_ deaf=no on gmond which is only sending data to some aggregator (only udp_send_channel, no rcv channels or tcp channels) generates some negative energy here. And that was it. My mistake was that I thought that when deaf=no is set than it doesn't matter as in UDP unicast we just don't listen - unless we have recv_channel configured. So I think that this could be a bug - not a feature. What's your thoughts on this? |
