Slow discovery

Hi Team,

 

We have 5 probes connected to a UCMDB 10.10 server and find discovery happening but very slowly.

 

We have tried various options with HP's guidance and also increased the Java Heap size, diabled all location probes and ran just 1 probe which has many subnets to be scanned.

 

We then stopped the probe services and the ucmdb server services and restarted the jobs and found in 30 mins (100 CI's were added). This again stopped in sometime.

 

Please find the errors attached from the probe.

 

Request your thoughts.

 

Regards

Mathew

Re: Slow discovery and .HPROF files

We find .hprof files gathering in the bin folder.

 

Is there a way to eliminate this completely so we get our desired discovery results.

 

Please advice

Re: Slow discovery and .HPROF files

Hi ,

 

What are the jobs that is taking alot of time to finish?

Did you tried customizing those Jobs?

 

Normally when hprof files are created is because there is OOM issues on the Probe, normaly to figure what is causing this issue we should investigate the hprof file.

 

Other recommendation is to customize the Jobs schedule to run in different time and not at the same time to avoit that Probe memory get overload.

Also a huge ip ranges cause OOM on Probe, so please try to customize the ranges if is posible.

 

Increasing java heap Memory willbe a good WR but firts you should take in count the last customizations after that you can increase heap M in chunk in order to avoid any Probe crash.

 

Hope it helps.

 

Best regards,

Re: Slow discovery

Hi Jason,

 

Thank you for your reply.

 

Looks like the .hprof files have stopped occuring. We added some  extra space and CPU cores and rebooted the server. However, we do not see any new discoveries happening in the application.

 

The probe status shows running for various jobs but the Zone based discovery is showing the same % for basic, infrastructutre and inventory and no new CI's are added for nodes.

 

How do we check if the new IP that are being scanned is loading or being pushed into the application? Do we have any troubleshooting steps?

 

Please advice.

 

Thank you.

 

Regards

Mathew

Re: Slow discovery

Hi Mathew,

 

Could you please upload new Probe logs?, after you increase CPU and Memory.

To verified the job status do the following:

1.Log on the probe with port:1977

2.Click on JobsInformation

3.Choose view jobs statuses.

4.Chose false for both:

5.Invoke it

There you will be able to confirm if Probe is running the discovery.

If there is no Jobs, I'd suggest to check unsent result on the probe side in such situations. It could be done by :

1.Accessing JMX console on the probe at http://probe:1977.

2.Use  GwTaskResultDistributer method.

3.Unsent results will be under NumberOfUnsentResults key.

 

If there is alot of unsent results, it means Probe is stuck.

 

Next step should be:

1) deactivate jobs,

2) stop the probe and the probe manager services (the probe db must be running)

3) go to \hp\UCMDB\DataFlowProbe\tools and run the clearProbeData.bat tool (if the tool cannot be executed directly, run it as an administrator and don't forget to add Probe pwd).

 

Hope it helps.

 

Best regards,

 

Jason Montero
