Proxy not collect data

[geyao1266]

hi all, I have a strange problem here.My zabbix system is 1 server,3 proxies,zabbix version is 2.0.9,server database is oracle 11.2.0.4,proxy database is mysql 5.5.At begin it works well,but suddenlly proxies don't update data from any host.If I add a monitored host with proxy , all the status(zbx/snmp/jmx/ipmi) are grey.I adjust the StartPoller and Timeout ,but it still the same.
any advice is appreciated !!!!!

zabbix_proxy.conf

ProxyMode=0
HostnameItem=system.hostname
LogFile=/tmp/zabbix_proxy.log
ProxyLocalBuffer=24
ProxyOfflineBuffer=24
DataSenderFrequency=3
StartPollers=20

LogFile=/tmp/zabbix_server.log
StartPollers=15
StartPingers=2
CacheSize=512M
CacheUpdateFrequency=60
StartDBSyncers=16
Timeout=30
LogSlowQueries=1000
ProxyConfigFrequency=1

LogFile=/tmp/zabbix_proxy.log <-- What is in that?

Is your zabbix_proxy process running on your proxies?

Also, Are your proxies showing as reporting in to Zabbix App server lately? In Administration --> DM --> (Dropdown box at top right = "Proxies")
See screenshot at the bottom of this post.

Lastly, look at the last paragraph and graphs in this post. if your Zabbix configuration needs tuned, these graphs will show what needs adjusted: https://www.zabbix.com/forum/showthread.php?t=41219

thanks for reply.
zabbix_proxy process is running well
see the attachment.

I don't know if it's a tuning problem or just a setting problem.A host monitored by proxy only collect 5 items but the templete it linked has 23 items.
It is to say the proxy only collect a part of items.So strange!!

Have you recently changed any of your items from item type of Zabbix Agent to Zabbix Agent (Active) ?

For example, If you look at that log, your Zabbix server is trying to send the list of active checks to a host named "IIM_DB". Does IIM_DB exist in your list of hosts in the Zabbix GUI? And if it does, is the letter casing an exact match? (In this case, everything is upper case)

And on your IIM_DB host in the zabbix_agentd.conf file, do you have a parameter defined as ServerActive= and after that = sign should be the IP or FQDN of your Zabbix server.
