FusionReactor start agent without listening

[Christoph Witzany]

Hi!

Please excuse when I missed a topic or did not find it in the docs.

- Is it possible to monitor a server with the java agent without opening a port?
- How would I send the monitoring data to a central FRAM server?

thx
Christoph

Hi Christoph,

You can also talk to FusionReactor directly via the web port (typically port 80):

You would enter the following URL into FRAM on the Manage Server page:

ColdFusion server:

http://<ipaddress>/fusionreactor.cfm

JSP + Servlet server:

http://<ipaddress>/fusionreactor.jsp

or

http://<ipaddress>/fusionreactor

To disable the internal port (e.g. 8088) you would need to remove the ,address=8088 option from the -javaagent option in the JVM settings.

For example: 

-javaagent:/Applications/FusionReactor/instance/jboss1/fusionreactor.jar=name=jboss1

When FusionReactor starts up you will see a message in the standard out like:

INFO FusionReactor FW: Bootstrap: Ascending to runlevel 2 

[INFO] Jetty not started (HTTP and HTTPS disabled)

Note that FusionReactor is accessible via the website

Hope that helps,

To add to Darren’s comment, someone might read Christoph’s question, “Is it possible to monitor a server with the java agent without opening a port?” a little differently (or may see Darren’s answer and wonder): “is it possible to access the FR interface without needing to open its port in the firewall”. It is, but it requires a slight variation in the URL Darren offered.

If one wanted to access the FR interface (in their browser) this way (without using the FR built-in web server port, but rather by way of their external web server), then they would need to add /findex.htm to the URL offered, as in (for CF servers):

http://<ipaddress>/fusionreactor.cfm/findex.htm

Again, Darren was offering the URL as would be to put into FRAM’s “Manage Server” page, which does typically end in /fusionreactor, and that’s why he showed his URL ending in just fusionreactor.cfm. If you try that in your browser, you may get something (as I do in IIS) saying, “FORBIDDEN: Reading file failed.” :-)

Hope that’s helpful.

Thank you! That's great to hear.

As to my second question:

How would I configure the agents on the servers appserver[1..9].example.com to deliver their metrics to fram.example.com?

As I'm looking at a deployment with 40+ app servers I need a central instance to present all the data centrally.

Got the answer already from support. You ad <hostname>/fusionreactor as url when you add a server in the management interface.
