why after upgrade zabbix 2.0 to zabbix 2.2 then server performance dropped

[mdk]

Hi
my zabbix server use SNMP monitoring on devices and all monitored hosts are devices.



my machines:
two servers(HA): 8 core + 24G mem
two proxy: 8 core + 24G mem
DB:24core + 64G mem

now zabbix server vps : 1500

Configuration parameters are tuned on zabbix server and proxy.

Hi mdk,

It looks that Zabbix performance queue metric very high ! I would recommend to check your zabbix_server.log and check any similar error such as:

SNMP agent failed with network error ...
If so, then try to increase TimeOut value in zabbix configuration section:

### Option: Timeout
#       Specifies how long we wait for agent, SNMP device or external check (in seconds).
#
# Mandatory: no
# Range: 1-30
# Default:
# Timeout=3

After restarting the zabbix server process, keep an eye if the queue value if it is being decreasing.

If this does not change anything, we could assume to escalate such performance issue to other level !

In the other hand, have a look to this useful link:

I hope it helps!

thanks
my proxy logs show most like:

......first network error, wait for 15 seconds........

and timeout also set to 30s after I upgrade to 2.2
