<div dir="ltr"><div>Greetngs</div><div>Centos6 64 bits machine, liboping 1.5.1, collectd 5.4.1.</div><div><br></div><div>I am trying to use collectd to monitor ping time and interface traffic of upwards of a 150 hosts, using ping plugin. If I configure all of them, however, the plugins reports high number (up to not getting any data at all) of NaNs on hosts that are perfectly (o)pingable from the CLI. I have worked on pinpointing the problem on the number of configured hosts:</div>
<div><br></div><div>failures begin when trying to ping upwards of 59 hosts, at which point the collectd process has about 63 sockets open. So it seems someone is having a problem with more than that amount of sockets. It does not appear to be a hard limit, however, because, configuring 116 hosts in theing plugin, I can see collectd opening 118 sockets. So it could be a per thread thing or something within liboping or....?</div>
