Since the poller showed it responded, I thought so, but I did look on the wiki (http://www.observium.org/wiki/Unix_Agent) and under testing did what it showed;

telnet stats.domain.com 6556
Trying 10.83.11.5...
Connected to ec2-....... amazon.com
Escape character is '^]'.
<<<check_mk>>>
Version: 1.2.0p3
AgentOS: linux
PluginsDirectory: /usr/lib/check_mk_agent/plugins
LocalDirectory: /usr/lib/check_mk_agent/local
AgentDirectory: /etc/check_mk
OnlyFrom:

So that did confirm. The remote host is running Ubuntu 12.04LTS and under /usr/lib/check_mk_agent I have the apache script. I tried to run it locally and had a perl LWP error so added that, now when I run it local I get;
Data fetch failure.
I am not sure if that's normal since it's being run local, or that is where the problem lies.

Tnx

Observium doesn't hit apache directly. That is done via the agent script.

Is it working?

After a successful implement of the mysql module, I now am looking to monitor apache. I will try to give as much on the 1st post as I do now understand how the agents work a bit more (Thanks Adam) so the info and questions are;

Unix-agent is installed, enabled, port is open, and I can hit the server-status from the observium server via curl;

curl stats.domain.com/server-status

So, it seems the agent is running, apache is reachable by the server with the server-status, just not sure why the graph page is broken. The main graph's all say Error Drawing Graph, and the scoreboard at the bottom just has a few broken image links.
