Operations Monitor 3.0 fails to reload - can't connect to QRS with REST connector

[korsikov]

Hi Tyler.

Can you help me. I'm have dev server w2012r2 with installed QV 12 desktop, QV 12 server. I'm deinstall QV 12 server and install QS 3.0. and faced with problem - operaion monitor not reload.

Reload stop on line " LIB CONNECT TO 'qrs_user';"

with error "Could not fetch connection by name using identifier qrs_user: LIB CONNECT TO 'qrs_user'"

Operations_Monitor_Reload_Stats_3.0.0.txt in attach and task log too

I think may be the cause of conflict with any previously installed QVRestConnetor, but why Licence monitor reload success.

Hi Tyler,

I have created Archive folders but still it is not loading , Please help me to fix it

This is a Qlik-supported app, so you can submit a help ticket.

What they (and I) would ask for are:

• Version of Sense
• script logs from the latest reload of the apps (in ProgramData\Qlik\Sense\Log\Script)
• Environment:
  • single vs multi-node
  • Any virtual proxies or changes there?
  • Version of sense
  • prior version of sense
  • Shared persistence? (and location of ClusterShare)

Aha - DNS error.

Make sure your DNS is working okay -- you might need to run the ip flush (I forget the exact command) or check the data connection URL for the qrs_app for example. Is it pointing to "localhost" or to a server name?

[rohitk1609]

Below path is mentioned in QRS_APP connection:

CUSTOM CONNECT TO "provider=QvRestConnector.exe;url=http://localhost/qrs/app/full;timeout=180;method=GET;autoDetectResponseType=true;keyGenerationStrate..."

I am trying to run IP flush command , will update you

[Tyler_Waterfall]

Weird. So the server that is reloading the Operations Monitor is not resolving the "localhost" DNS.

I confess this is a bit out of my expertise (I would tell you DNS = donuts )

Flush DNS - What's My DNS?

Hi Tyler,

Okay, I agree we don't know how to resolve it, just help me to know, what exactly happened and what precaution I will take to avoid it ?

[Tyler_Waterfall]

When in doubt, use the fully-qualified domain name (FQDN) instead of "localhost" in the data connections.
