Monitor association that references a monitor template that does not exist.

Hello,

 

 

I'm running into an issue where an instance of a LBPoolMonitorAssociation, returned by LBPool.get_monitor_association(), has a LBMonitorRule that references a monitor template that does not exist.

 

 

Consequently, when I call Monitor.get_template_destination(template_name), to retrieve the IP : Port for the template, I get the following error message:

 

------------------------------------------------------------------------------------------------------------

 

Exception caught in LocalLB::urn:iControl:LocalLB/Monitor::get_template_destination()

 

Exception: Common : : OperationFailed

 

primary_error_code : 16908342 (0x01020036)

 

secondary_error_code : 0

 

error_string : 01020036:3:

 

The requested monitor template (xxx ltm_obj) was not found.

 

------------------------------------------------------------------------------------------------------------

 

 

I'm not sure what event caused the template not to exist. Under what conditions can this happen? Is it possible to remove a monitor template that is currently part of a monitor association?

 

 

Thanks,

 

Eric

    Eric,

     

     

    This sounds like a corrupt configuration to me - does this pool & monitor look OK using Web GUI?

     

     

    " The requested monitor template (xxx ltm_obj) was not found. " basically means you asked for a non-existent monitor name.

     

     

    Try doing a "b save" from the command line and look at the bigip.conf file to see if indeed somehow you have managed to have a non-existent monitor reference in the pool definition.

    No, the monitor does not show up in Monitors but does show up as attached to pools.

     

     

    >>see if indeed somehow you have managed to have a non-existent monitor reference in the pool definition

     

    Looking at the conf file was what led me to discover it was a monitor association that references a monitor template that does not exist. Over 10 pool definitions reference a monitor that does not exist.

     

     

    Is a corrupt configuration the only means of causing this problem?

     

     

    Is it possible to remove a monitor template that is currently referenced by pool definitions via the iControl API?

    To answer your second question:

    I tried to delete a monitor template which is associated with a pool using iControl and got a SOAP exception: 

    Exception caught in LocalLB::urn:iControl:LocalLB/Monitor::delete_template() Exception: Common::OperationFailed primary_error_code : 17236099 (0x01070083) secondary_error_code : 0 error_string : 01070083:3: Monitor test_monitor is in use

    With regards to the first question - difficult to say what caused this- it iooks like that your box's config could be in a strange/unstable state, so I would not try to make sense of any iControl errors until you get the box to run in a stable configuration.
