Hi Tobias, Thank you for your reply. Tobias Oetiker wrote: Thank you for that suggestion. I will try rrdtool 1.3 when I get a chance. We are currently using rrdtool-1.2.99907080300.I have not yet done setups of this scale, but having multiple fpings running in paralell is certainly a goood thing ... I would not think that you are disk bound with only 6400 targets ... especially not if you have plenty of memory ... Also moving off xen to real HW should help ...If you use rrdtool 1.3 you may be able to reduce your cache consumtion and improve performance ... The individual processes do not use that much. I got that value by adding the memory usage of all of the probe processes. Each of the 30 probes uses somewhere in the neighborhood of 115-120 MB. Is that due to the fact that results are all stored in RAM and then written to disk all at the same time? I've noticed that there are a fair amount of writes that take place across the interval, but there seem to be large writes and high disk utilization all at once.that does sound odd ... your smokeping process uses 3.5 GB or RAM ??? I will have to talk to my boss about that. Thanks again.Glad to hear smokeping makes you happy. If you want to make sure it continues to evolve you could always become a sponsor and ensure its continued development ... |
