Performance problem

[Aer0]

Hello!

I'm trying to find out the cause of my problem with Zabbix server performance.

I have queues on my server:
1) Simple check - "More than 10 minutes" - 20 000+
2) SNMP agent - "More than 10 minutes" - 10 000+

In my Zabbix i have self-performance monitoring items:
Utilization of vmware collector data collector processes, in % - 88.2497 %
Utilization of poller data collector processes, in % - 70.5394 %
Number of processed values per second - 295.4793 vps

Other Items are OK.

In my conf files i have:
StartVMwareCollectors=15
VMwareFrequency=60
VMwareCacheSize=32M
VMwarePerfFrequency=60
VMwareTimeout=120
CacheSize=256M
StartPollers=30
StartAgentPollers=15
StartSNMPPollers=15
StartPollersUnreachable=15
StartPingers=15

What can be wrong?

What is the difference between Pollers and Collectors in Zabbix?

Looks like i have anough Pollers but my Collectors are overloaded?

I can't find how i can increase and make more data collectors.

it is the same... "pollers" <-> "poller data collector"

70-80% is high utilization... If you add more pollers, does the mnumber come down?

Yes, looks like that helped.

What i've done:
StartVMwareCollectors=15 -> 30
VMwareFrequency=60
VMwareCacheSize=32M
VMwarePerfFrequency=60
VMwareTimeout=120
CacheSize=256M
StartPollers=30 -> 60
StartAgentPollers=15 -> 30
StartSNMPPollers=15 -> 30
StartPollersUnreachable=15
StartPingers=15

In the simple words: i've double the numbers of four parameters
1) StartVMwareCollectors
2) StartPollers
3) StartAgentPollers
4) StartSNMPPollers

Now i have 0 all my in queues.
