active check howto

[Philippe]

hello,

i would like to test with active checks.
i configured a pc with zabbix agent and changed the agent configuration file for active checks.
i added one item for this host and it is "agent of zabbix running", it's just to test how active checks work.
in the logfile i get:

i don't see data in latest values.
what am i doing wrong ? how does active cheks work ? can i check everything with active checks ?

thanks,
Ph.

[Philippe]

i also tested with older zabbix clients on windows.
With older clients i get no errors, but also nothing in latest values.
is there a problem with zabbix 1.4.1 active checks ??

[Philippe]

is there really nobody that can help ? developers ?
could someone maybe post an example ?
thnx, phil.

[sylvain]

up! i managed myself to get it working only one time (i have upgraded to dev source then downgraded again with 1.4 with recreating of database of course)

[Philippe]

so i can consider active checks in alpha state as nobody seems to get it working ?

[marc]

active checks should work properly. make sure Hostname in conffile == Hostname from gui even if you connect to an ip address.

[Philippe]

Hello Marc,

thnx for your reply.
Active checks work now, my hostname was the real name of the computer and not the gui name in zabbix.
changed it to the same name and now it works.
thnx for your help!

grtz,
Phil.

HELP: Hostname trick not helping

Have the same problem. Even tried to get the hostname the same on zabbix server (gui), in zabbix_agentd.conf and on the W2K3 server itself.
I'm doing a --stop, --uninstall, --install, --start between each test. Still the PdhCollectQueryData error.

The hostname in the Zabbix frontend and the zabbix_agentd.conf must be the same. It doesn't have to the same as the server hostname but it does make it easier to identify which server is being monitored. It could be fred:fred.

You need to ensure that there is a path from the server being monitored back to the zabbix server. An easy way to check is to run from commandline

telnet ip.address.of.zabbix-server 10051

assuming your zabbix server is listening on port 10051.

Ensure that Active mode is not disabled in the zabbix_agentd.conf file.

Make sure that the items you are monitoring are set to type 'ZABBIX agent (Active)'.

Hostname both on GUI and in zabbix_agentd.conf is CLIENT.sys1 (names changed for privacy)

Was ok.

Have DisableActive=0

Guess this will be the problem. They are all on "zabbix agent".

For the moment it works with the older 1.1.6 version of the zabbix client. Maybe I should leave it this way till I upgrade the server to 1.4.1 and then change all the items.

[gedp]

Have tried with setting to "zabbix agent (active)" for all items on that box, but still have the same problems.

Could it be that there is a problem running the 1.4.1 agent with the 1.1.6 server?

Definitely. 1.1.6 agents work on 1.4.1 servers. Not the other way around.
