Zabbix Agent Active Check

[mawoh]

Helle everyone,

yes I know this is an neverending story but please, I need help for the active agent check :-)

For begining a simple example-scenario.

I have a client (ip:192.168.1.50/ name: testclient) and the zabbix server is 192.168.1.200 with the name zabbixserver

It is an windows environment. I use the setup-installtion-tool for the agent.
Now I want to edit the agent`s file, but I don`t exactly know which line I have to edit, or have I to uncommend the lines ?

perhaps you could tell me which lines I habe to edit to get an active agent, and how I can setup the active agent in zabbix.

here is the agent-file:

I also set the item to active check. the hostname in zabbix environment and in the agent file are also the same. there is still the message "cannot connect"

thx again for the fast answer :-)

[ruswold]

check port 10051 - standart port for active checks. It must be open.

[mawoh]

port was/is open

[ruswold]

port was/is open

open on client direction out and server direction in?

Set DebugLevel=3 in zabbix agent, restart service and you see in log like

2660:20100630:160655.302 Zabbix Agent started. Zabbix 1.8.2 (revision 11189).
2672:20100630:160655.321 zabbix_agentd collector started

2700:20100630:160655.340 zabbix_agentd active check started [ZABBIX_SERVER:10051]

and no any errors!

My zabbix_agent.conf very simple

Server=IP_ZABBIX_SERVER
ServerPort=10051
Hostname=HOSTNAME
ListenPort=10050
StartAgents=5
DebugLevel=3
LogFile=C:\WINDOWS\temp\zabbix_agentd.log
Timeout=10

and active checks work

this is my logfile: do not be confused, the real server ip is 192.168.1.206

here I`ve got a new logfile entry:

[ruswold]

Show your item "status" that used active check.

[mawoh]

do you mean this ?

[ruswold]

do you mean this ?

yes.

Can you describe what is it status?

[mawoh]

status is active

[mawoh]

now I`ve got an new error messag: got emtpy string. assuming that dropped ....

[mawoh]

:-) it works !!!

after deleting and recreating the host it works. hm strange.

I say so much thank you to you ruswold. thx a lot.

but one little thing is missing. I don`t get information about the host status. free space / memory / cpu etc works fine, but the host status is not supportet. what can I do ?

[ruswold]

status is active

Sorry for my English.

I don't mean this. I understand that it's active, but i don't find check "status"

I think you may use agent.ping.
