Hyperic HQ-Agent

[sju2402_hyperic]

Hi everyone,

We try to use Hyperic HQ to monitor our webs servers. I have searched internet about using it without installing HQ-Agent, but it looks like that it's necessary to install the agent for HQ-server to monitor it. Is that possible to monitor web server without installing the agent ? Any good recommands for tools to monitor web servers without installing any agents ?

Hi,

there are several options. You may setup a HTTP check, according to the description in the review guide:
http://download.hyperic.com/pdf/hq-trg-32.pdf

or you deploy a central HQ Agent installation and configure several Apache server instances which point at your webservers. Apache monitoring is based on the Apache modul mod_status to provide infos about the status. The second solution is more complex, while the first one provides only basic informations.

But you'll have to install at least one Agent (not necessarily on on one of the webservers

Yes and no...

You did not specify what you want to monitor. I assume you want to monitor
the availability of one or more websites through HTTP requests.

You will need at least one agent running somewhere to do the measurements,
as the HQ server only receives data from agents and does not do any monitoring
itself. This agent need not be running on the webserver in order to do HTTP
checks. For instance, you could use an agent running on the HQ server.
However, this way you will not be able to get any "local" monitoring data from
the webserver (e.g.: webserver process status, memory usage, etc.), unless
you create another way to make this data available to the agent that monitors
the webserver (e.g. through SNMP or SSH), but then you will probably need to
create a custom plugin for this. In that case it is probably better to just install
the agent on the webserver(s). Why would you not want this?

please excuse the redundancy of my post; I hadn't seen Mirko's reply yet...
