"host [scmonitor] not found"

That looks like a problem! Zabbix Server doesn't know about that host.

Be sure that the name that you have set in your zabbix_agentd.conf, is exactly the same as the name you have given your host in the zabbix gui, case sensitive.

# Unique hostname. Required for active checks.
Hostname=scmonitor

Also, it may not be absolutely necessary, but I would use the real IP address rather than 127.0.0.1

Don't forget to restart the agent after you make changes.

HTH,

Some progress...

Hello all,

I have managed to solve some issues, the connect failed problem went away, seems that my entries in the /etc/services failed weren't done properly.

But I still get the host not found errors both in the agent log and the server log.

Here is what I get now when I start the server:

Code:

And here is what I get when I start the agent:

I made sure that the hostname parameter in the /etc/zabbix/zabbix_agentd.conf file did match the value entered in the front end and that the Server parameter has the IP address and not the loopback address.

Could it have something to do with the hosts file config? Just in case, here it is:

[CODE]127.0.0.1 localhost
#127.0.1.1 scmonitor.xxx.xxx scmonitor
10.28.32.237 scmonitor.xxx.xxx scmonitor

# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
CODE]

Any ideas?

You still have "host [scmonitor.xxx.xxx] not found" in both the Server log and the Agent log.

Also, the Server log still has a reference to 127.0.0.1
"Got empty string from [127.0.0.1]

You changed the IP address in the zabbix_agentd.conf, but did you also change the Host IP in the gui.

Another source of confusion for many people is the Hostname in Zabbix. On the Configuration --> Hosts gui page, the first three columns are Name, DNS, IP. In zabbix the Host or Hostname refers to the first collumn 'Name'. Name can be anything you want, e.g MyServer, QwertyNMS, BilliesStuff, etc. The name has nothing to do with DNS. So a name like 'scmonitor' is okay, it doesn't need to be 'scmonitor.xxx.xxx' but it can be if you want - so long as it is exactly the same in the gui and in the conf file.

You're getting closer.

Getting closer...

I think you really nailed it MrKen. Seems the differences in the name column caused this. Everything is uniform and working!

Thanks MrKen!
