I need recommendations to increase performance on our smokeping server. We are running smokeping 2.2.3 with rrdtool-1.3beta1 on a Dual Xeon 2ghz machine with 2g of ram. I'm not sure of the hard drive specs, but I believe they are at least 10K rpm Serial Attached SCSI.
We currently have 6200+ ip addresses to ping, with that number increasing every few days as we add stores, and we would like to ping them 15-20 times, if possible, every 5 minutes. When I initially set this up, I created a number of different FPing probes with a script that creates the smokeping config file, dividing the ip addresses up into the different probes somewhat evenly. So, my questions are these: 1. Since each smokeping process and corresponding fping process take up their own share of system resources (disk I/O, cpu, memory), am I better off keeping the number of probes fairly low (< 5) or am I better off creating another probe each time there are another couple hundred ip addresses? 2. Do my rrd settings affect whether the probes finish in their allotted time or not? By settings I mean the AVG, MIN, and MAX hb, steps and total settings. 3. I am currently using an offset of 0% for each probe, because I don't care about how utilized the network becomes at this point, as well as a mininterval and hostinterval of 0.001. I also have concurrentprobes set to yes. Are those settings reasonable and do I need to be looking at other parameters? 4. Is it possible for us to achieve the goal of 15-20 pings per ip address every 5 minutes with this hardware? Thanks in advance. Jeff Williams
