I think I've asked this question before but I don't think anyone has ever indicated any possible solutions.
I currently graph 2200 targets and that number will grow. We're using MRTG 2.9.11 on a DELL Poweredge 2300 Server with Dual PIII 500 and 512 MB of RAM. We're running MRTG in daemon mode with the possible forks set to 4. As it is currently if one of our monitored routers goes down for any length of time it blocks all other graphs from graphing. I've tried modifying the default SNMP session values to only doing a single retry, to hopefully ease the blocking. So far I haven't noticed a benefit in terms of blocking and graphing outages. I have been told that we need to monitor on each router in/out traffic,collisions,crc's, and some signal/noise on some routers. Perhaps this is trying to do to much on one router, however, I need to see if it's possible to set up mrtg so that it graphs seemlessly when one router goes down. Has anyone seen anything similar to this? Has anyone resolved this? Is there any way of integrating target configs into mysql or any sql database such that a wrapper program could determine if there is a non-responding device and take it out of rotation, while periodically performing a check to find out if the device is avaliable again? I wish I could write it myself. Can perl take advantage of multiple threads?
