All, In trying to get 1500+ hosts working on single smokeping system. After running smokeping for several days, yet not recieving any output on the graphs I began measuring the time take to run smokeping *once* across a given number of probes. There was a thread sometime ago that did cover this but no clear conclusion was drawn...( http://www.ee.ethz.ch/~slist/smokeping-users/msg00237.html and http://www.ee.ethz.ch/~slist/smokeping-users/msg00236.html)
The server I am runnning is running is a dual 733Mhz with 512Mb RAM with no signicant load. It is running smokeping 1.18, Linux kernel 2.4.19 and perl 5.6.1. Here are the timings for given number of targets... #(root)-(1)-(ops1) -=> time /usr/sbin/smokeping --nodemon --debug ### fping seems to report in 1 miliseconds Launched successfully FPing: probing 527 targets /usr/sbin/smokeping --nodemon --debug 1.37s user 0.93s system 1% cpu 3:36.37 total #(root)-(0)-(ops1) -=> time /usr/sbin/smokeping --nodemon --debug ### fping seems to report in 1 miliseconds Launched successfully FPing: probing 764 targets /usr/sbin/smokeping --nodemon --debug 1.41s user 0.30s system 0% cpu 5:16.26 total #(root)-(0)-(ops1) -=> time /usr/sbin/smokeping --nodemon --debug ### fping seems to report in 1 miliseconds Launched successfully FPing: probing 1030 targets /usr/sbin/smokeping --nodemon --debug 2.06s user 1.68s system 0% cpu 7:22.21 total #(root)-(0)-(ops1) -=> time /usr/sbin/smokeping --nodemon --debug ### fping seems to report in 1 miliseconds Launched successfully FPing: probing 1279 targets /usr/sbin/smokeping --nodemon --debug 22.89s user 11.05s system 5% cpu 10:49.68 total The times above excludes the generation of the .rrd files as I ran the above command twice to ensure they were created... I have seen some documentation that some probes (that can take only a single argument) maybe forked for scalability. Does anyone know or have fping forking. I imagine to do this the number of targets per fping would be limited (i.e. 100) and you would run a number of these in parallel to scale...? Tobi, thoughts suggestions?
