FHtml: Mode is invalid

[chris hough]

not sure how to ask this, but when I click the link to "Recent Slow
Pages" for a given instance the error message "FHtml: Mode is invalid"
displays. any ideas on how to troubleshoot / fix this? I am clicking
the link from our FRAM, the primary server watching all of our
instances and this occurs for every instance.

Hello Chris,

It sounds like you may be trying to monitor FRAM itself from within
FRAM - eg if you add the URL of FRAM (typically port 8087) to the
Manage Servers screen it's quite possible to get this message.
To give you some background, FusionReactor is a generic Java server
monitoring tool. We can monitor any type of servlet container (eg
Tomcat, WebSphere, JBoss, Oracle AS, etc). FusionReactor itself sits
inside the JVM process, however there are a few cases when that is
undesirable (eg when the JVM process itself crashes). We combat this
by having a small Tomcat instance with FusionReactor running inside it
(FRAM). This gives us several benefits - ability to perform upgrades
through FRAM administration console, alert/react when JVM processes
fail, etc. However, the FusionReactor instance inside FRAM is slightly
customized to give a better user experience. One of the removed items
are the request pages - because it doesn't make sense to show you
requests to the FRAM instance, they're all our administration code
anyway. As such, if you were to mistakenly enter the URL to a FRAM
instance (default port 8087) - rather than a FR running inside a
"real" server (default port 8088+) - then it's possible to get this
message because you're trying to see the recent slow pages on the FRAM
instance - which isn't implemented.
Could this be your issue?

If not, if you could send a screenshot of the browser page (including
URL), a description of how you got to that error (eg the screen & URL
you came from) to our sup...@fusion-reactor.com address where we can
help you identify what you're looking at that would be great. I'll
also post the answer back here to the groups later so that others
finding this thread can see.

Best regards,

Sorry David, I will send these over to you now.

We are still getting the error message.  I never received a notice when you posted here, sorry for the delayed reply.

Thank you again,

Chris

Hi Chris,

Could you please try upgrading to the latest FR version. We fixed a
bug in the 4.0.x series relating to bad links from the Enterprise
Dashboard. I just checked this on my installation and it's working
fine there.

The latest version (FR4.5) can be downloaded from
http://www.fusion-reactor.com/fr/downloads.cfm and is a free update if
you have any FR4 license or a subscription or maintenance on an FR3
license that is still current.

Cheers,
Darren
