ZABBIX: crashtesting, records #2

....failed very fast, on lots of process the system starts to swap

fixed the buffer, the system does fine with 20 snmp threads with, about 25knvps

have significant queuening with 43k required nvps, try to make 30 threads


didn't help, changed delay from 90 to 120, zabbix somehow stopped to work normallu, restarted.

doesn't work either, reduced numbre of pollers to 20
queueing, 33nvps.....
raised pollers back to 40....

OK, 30NVPS ONLY SNMP - NO PROBLEM
changed back delay to snmp to 90s.... lets look
it still queueng but just above 10sec, at planned load of 43knvps

reduced delay of snmp to 100 sec,pinger still off, let' see
ok, the system is stable to complete zero queues at 33kNVPS of clean SNMP load.

Now, let's test the FPING 100 threads:
the old version could handle the load without big broblems with up to 1sec (1sec had quieuieng in the first column)

NMAP: 100 threads works worse then FPING
high system load,  32% idle

Reduced NMAP threads to 20:
It does just like 100 threads FPING but system idle is 62%

Reduced NMAP threads to 10: it's worse, 20 seems more optimal, it's 82% idle

Now try fping in 20 threads:

The normal SNMP is:
