UserParemeter not supported by agent

[evgeny elkin]

Hello all!
Use Zabbix 1.4.1, i want to check a timestamps of a folder with logs

UserParameter=timestamp,stat -t /home/zabbix/test/ | awk '{print $14}'

but status of item is Not Supported ((

Log:
8597:20071005:165014 Active parameter [timestamp] is not supported by agent on host [1313-3]
8597:20071005:165014 Type of received value [ZBX_NOTSUPPORTED] is not suitable for [timestamp@1313-3]

I uncomment the default parameter
UserParameter=system.test,who | wc -l
and test it - it works. But my UserParameter is not working

Any ideas will be very helpful for me, thanks!

Problem solved. Add the same item on the test zabbix server's host - ...and it's works! Restart agentd daemon on monitioring host and zabbix server daemon on server - iem starts working
