Zabbix agent (active) not running

[ChrisJackson]

I'm just starting to use Zabbix and i'm needing some help with setting up a Zabbix agent (active) item type so I can monitor a log file.


On a monitored machine

I have the /etc/zabbix/zabbix_agentd.conf modifications:

ServerActive=192.168.100.177

Hostname=Zabbix server

LogFile=/var/log/zabbix/zabbix_agentd.log

Server=192.168.100.177


And the log file im wanting to monitor:

-rw-r--r-- 1 apache apache 2220696 Mar 10 09:23 ssl_error.log


I have added the zabbix user to the apache group:

# usermod -a -G apache zabbix


Restart the zabbix agent

systemctl restart zabbix-agent


Now on the zabbix server HTTP web interface, I select the host and see the items list.


I click on the top right “Create Item”

Here is my item



I then go back to the items page and see “c_webError_1” in the list.


After waiting about an hour I don't see any data coming in on the Latest Data page




Advice?


Thanks.

On a monitored machine
I have the /etc/zabbix/zabbix_agentd.conf modifications:
ServerActive=192.168.100.177
Hostname=Zabbix server
LogFile=/var/log/zabbix/zabbix_agentd.log
Server=192.168.100.177

Is this monitored machine the Zabbix server?

No, this machine is one of many monitored machines. As I understood it the
Hostname=Zabbix server
is the main Zabbix server hostname.

This machine hostname is f-web-dev and this is also the
"Host Name" entered in the Host setup.

Also when I try and run
zabbix_agentd -t log[/var/log/zabbix/zabbix_agentd.log,,,,skip]

I get
log[/var/log/zabbix/zabbix_agentd.log,,,,skip] [m|ZBX_NOTSUPPORTED] [Accessible only as active check.]

[Markku]

That's because you cannot poll the active items. Active items mean that the agent periodically (every two minutes by default) asks the server for items to check, and then runs the item checks as configured, sending the data to the server.

No, this machine is one of many monitored machines. As I understood it the
Hostname=Zabbix server
is the main Zabbix server hostname.

No, the server is configured with the ServerActive command as you did. Hostname command specifies the identity of the agent, and that name should exist on the Zabbix server database as a host name, ie. the Zabbix server uses that name to match the incoming (active) connection for the correct host in Zabbix database. Replace it with f-web-dev.fordav.com (updated the host name as it is shown in the screenshot above).

That did it - thank you very much.
