Zabbix Agent does not send all the values

[Razique]

Hi all,
first of all, the 1.8.3 version is awesome!

I've an issue with a monitored host that does not send all the values. When I manually send the value via the zabbix_send binary, it works ; I mean, the server gets the data. The host is linked to the "Linux" template. I've 10 others hosts ; two of then are exactly the same servers (Proliant ones), with the same zabbix agent :
1.8.3 (server : 1.8.3)
Here is a screenshot of the monitored server (the fubar one) :


And a normal server :



It looks like the agent is not able to retrieve datas from the server (but even simple ones as the load :/)
when i perform a test via cli it works :

$ zabbix_agentd -t "proc.num[fail2ban-server]"
proc.num[] [u|1]

while this item remains in "unknown" state on the server (well except if i send manually the value, in that case, the trigger is now "OK".) I've recompiled the agent and checked two times the conf. and everything seems good.
any clues ?
Best regards,
Razique

Are these items configured as Zabbix Agent or Zabbix Agent (Active)?

Hi,
thanks for the reply, they are mostly actives items. Meanwhile, I resolved the issue. The hostname was written in lower case on the monitored server, and upper case on the zabbix server :
Monitored server :
Hostname=myserver-2

On the zabbix server :
Host= MYSERVER-2

I use the upper case and it worked
thanks
