[jffnms-users] Slow down - then crash

[Nick Knight]

Hello all,   I have a situation where my box which monitors 28 hosts, no auto discovery, they all monitor about 20 interfaces each. It has reached a point where the poller.php takes so long the next one runs and mysql stops allowing connections.   I have run poller.php manually to find out how long it takes, and it is exhibiting strange behaviour.   1/ I am getting a load of php warning about mysql duplicate functions   2/ It flies through a lot of the polling but after a small period of time it REALLY slows down, and starts taking about 10S for each interface, this doesn’t appear correct.   So a couple of questions,   1/ How many hosts/interfaces can a good speced server handle (2Ghz 512MB Ram) NB most hosts are across a WAN   2/ What may be responsible for the slow down? A specific host, - can time-outs be set?   Thanks   Nick   BTW great piece of software.
