FR instances connection lost

[raZorTT]

Hi,

I'm having a problem with some of the FusionReactor instances on my ColdFusion 10 servers.

On 2 servers 1 of the 4 instances is showing connection lost. I have tried uninstalling fusion reactor from the instance, restarting it and then reinstalling. Nothing so far has worked.

Can someone point me towards log files that might help diagnose the issue?

Cheers,
Simon

Hello Simon,

I'm sorry you're having trouble with FR on CF10.

Firstly, can you confirm you're running FR 4.5.2 (the latest stable as of writing)?

Can you also confirm that FR is installed and contactable via the URL that's listed in the Enterprise Dashboard (use the "Manage Servers" link to view/edit the URLs). The URL should be contactable from the server hosting the enterprise dashboard.

The logs of interest are your CF10 (E:\ColdFusion10\cfusion\logs\coldfusion-out.log) and FusionReactor (C:\FusionReactor\instance\<instance name>\log\<date & time>\reactor.log) logs. It's unlikely these logs will be of much assistance in resolving the problem - typically they'll tell you that there's an issue connecting to the URL but normally it's a case of a firewall blocking the connection or FusionReactor isn't listening properly on the expected FusionReactor URL.

If you need further assistance, please contact sup...@fusion-reactor.com

Best regards,

David Stockton

To be clear, are you saying that the Enterprise Dashboard for an instance is pointing at these others, of which some are not being connected? If so, look at the reactor.log for the instance running the dashboard, to see if it complains about a problem.

Or are you saying you get this while you have the FR interface for the instances in question? If so, you refer to uninstalling fr and reinstalling, so I assume that it’s not that CF itself is having a problem, just FR.

What is the URL that you’re using to open FR? Have you tried calling it from different machines (on the server and off)? Or if the URL is using the FR built-in web server port (like 8088), try taking it off. By default, FR can be talked to through an external web server (like IIS or Apache). In fact, you may find that if you are using an IP address (or localhost or 127.0.0.1) that you can use a domain name and add the rest of the FR URL, and the request may work (again, from the same server or from outside one).

Let us know if any of that helps.

Hi David and Charlie,

Thanks for the quick replies.

I can confirm I am running FR4.5.2 on RHEL 6.1

The FR instance that i'm trying to connect to isn't available from my browser using 10.11.23.20:8088/fusionreactor. A wget 127.0.0.1:8080/fusionreactor from the server also fails with a connection refused error. The firewall ports *should* be open. It had been working previously.

I looked in Manage Instances and confirmed that the port 8088 is where FR has been installed.

The ColdFusion instance that FR is trying to monitor is up and working fine.

Sounds like the issue may be FR not listening correctly. I'll take a look in the FR conf file, maybe there is something in there that explains it.

Cheers,
Simon

Oh and I have restarted the CF instance after re-installing Fusion Reactor.

[Charlie Arehart]

But have you tried accessing it without the port (so instead, through your external web server). Not only would that be a work-around until resolved, but it would help confirm that it’s indeed about that port or the built-in web server. That said, had you confirmed your system shows FR listening on that port?

Hi Charlie,

Without the port I get a page not found error.

When I do a netstat the port 8088 isn't listed. The other instances, 8089, 8090 etc do show up

Cheers,
Simon

[Charlie Arehart]

OK. Since you say you see nothing listening on that port, I would recommend you next check both the reactor.log (for the instance in question) and also CF’s cfserver.log (since you are on Linux). See the startup log messages for CF, and I suspect you may find why FR is not starting within that instance.

Or perhaps it’s starting on another port. To the FR folks, I find that the FR messages shown within CF’s startup messages do no report the port that FR is running on. Is that something that could perhaps be added to its startup messages?

Hi Charlie,

[raZorTT]

Thanks Charlie,

I jumped onto the server and found the following in the coldfusion-error.log file

INFO: FusionReactor Framework Host Manager - Initializing
FusionReactor is in bypass mode because it failed to initialize: null

Anyone know where I can get more information about might have failed?

I completely reinstalled the FR instance before restarting the coldfusion instance so there aren't any log files in /fr/instance/cfusion.cfmx10/logs

Cheers,
Simon

Hello Simon,

The most likely cause is that FusionReactor can't read the fr-osgi.conf file. The most likely reason for that is that the user owning the CF process doesn't have permission to read & write (/own) the "/fr" folder. It needs to be able to read, write and create new folders&files (that it can also read, write & delete) in the "/fr" folder and all sub-files & folders.

Can you check your permissions please?

Best regards,

David Stockton

Hi David,

Thanks for the reply. 

I've just logged in from home to have a quick look at the permissions. There is no fr-osgi.conf file in the instance that I am having a problem with.

It also seems to missing the majority of the env folders and files. It's missing the runtimefw and sys directories and 5 jars from the env/bundle directory.

I'm not sure if these files a created when the FR instance first starts, but I thought i'd mention it in case.

Cheers,

Simon

Hi David,

Also as far as permissions go I have the following:

drwxrwsr-x  /opt/fusionreactor - owned by the coldfusion user and the group is the coldfusion/apache group

drwxrwxr-x  /opt/fusionreactor/instance - owned by the coldfusion user and the group is the coldfusion/apache group

drwxrwxr-x  /opt/fusionreactor/instance/cfusion - owned by the coldfusion user and the group is the coldfusion/apache group

drwxrwxr-x  /opt/fusionreactor/instance/cfusion/osgi - owned by the coldfusion user and the group is the coldfusion/apache group

Cheers,

Simon

While you await replies from your later notes, can you check the cfserver.log rather than just the colfusion-error.log? The former may show more than the latter (with respect to info shown during the startup of CF, which may be helpful.)

Hi Charlie,

I restarted the CF instance and I couldn't see anything in server.log

Hello Simon,

I'm sorry things still aren't working for you. The fact there's no fr-osgi.conf file is in itself a problem. The most likely reason is that the permissions were "off" at install time and have since been updated. The simplest thing is if we can organize a quick screen-share & call and we'll fix / re-install FusionReactor as necessary. Please contact sup...@fusion-reactor.com to organize this.

Best regards,

Hi David,

Thanks i'll be in touch soon.
