Hi All

I recently installed this software from ManageEngine AppsManager9
W installed "perfservlet" in the Portal We are running (WebSphere Portal 6.1.5) to acomodate the monitoring.

But on each of the monitoring interval SystemOut.log recorded :

SRVE0255E: A WebGroup/Virtual Host to handle / has not been defined.

To confirm that it has something to do with the monitoring
Whenever we execute this url :

hostname.domain.com:10040/wasPerfTool/se...

System Out throws out below Error msg
SRVE0255E: A WebGroup/Virtual Host to handle /favicon.ico has not been defined.

Can anyone advise me how to adjust the Virtual Host to rectify this?

Thanks

Verify the application is mapped to the correct virtual host in the application attributes and if so, verify that your virtual host definition has host aliases setup for the specific host and port combinations.

Hi Erik

Thanks for the quick reply, I have to say i am quite new to the
world of WebSphere.

So I am not quite clear on the suggestion you asked me to
verify before.

I checked under Ent App > Perfservlet > Virtual host as screen
shot below and it is pointing to default_host

and the confirguration in Virtual host are as follow :

is this the configuration you were refering to ? if so what config that i need to adjust?

Thanks again for you help.

 

 

You configuration looks good so far, but there are numerous other considerations...

1. Are you using Administrative Security?  If so you may need to specify the username and password of a user who can access the servlet.

2. Verify your SOAP END PORT is correct

If you haven't come across these links, they may offer some assistance:

www.ibm.com/developerworks/websphere/lib...

publib.boulder.ibm.com/infocenter/wasinf...

Regardless of the version of platform you run WebSphere on, the above links should still be accurate.  Additionally, the perfServlet hasn't changed much after version WAS version 6, so these links should still be applicable (I'm not positive on WAS 8.0 just yet as I haven't deployed it in my environments.)

You can also try dropping the arguments after /perfservlet to see if you get anything.

Another link worth looking at is: josephamrithraj.wordpress.com/2010/07/08...

The data here is written by Joseph who is another very active GWC member.

You can always try restarting the JVM where your app is deployed.  I can't recall if you must restart it after making changes to the virtual host definition.

In my enterprise, I do not leverage the defaulhost definition and instead opt to create a new virtual host for every application.  It's personal preference, really, but I find that some applications have additional mime type entries that other applications are not approved to process.  By using different virtual host definitions per application I can provide the granularity needed for each application and ensure that each application is served correctly.  Again, personal preference here, but this is ideal for me.

Good luck and let us know if the above helps.
