LMS 2.6 User Tracking - minor trackin not running

Unanswered Question


I have LMS 2.6, Campus Manager 4.06 on a Solaris platform.

User Tracking is configured to run minor acquisitions every 55 minutes. However, I don't believe minor acquistition has EVER run. It is now 9am and the last entry I see in the UT.log is from 3:54am (my last Major acquistion ran at 3am). Any ideas?

Doesn't look like Minor Acquisition logs to ut.log. Mine's not been written to since midnight when Major acquistion last ran.

Have you enabled any UT debugs (vmpsadmin module)?

How many end hosts are you normally discovering?

You can enable vmpsadmin debugging under Campus Manager > Admin > Campus Data Collection > Debugging Options, then check the ani.log to see if it's kicking off the minor acquisition. Note: a minor acquisition only looks at devices that changed during the last Campus Data Collection. So, if nothing has changed, or a Data Collection has not been run in the last 55 minutes, then the minor acquisition will just start and stop.

I'm starting to understand.

I want to know if a PC has moved to a different switch or even a different port on the same switch.

Could you please tell me if the statements below are true.

If a Major UT Acquisition is run, it will pick up the change.

If a Scheduled Data Collection is run, and then a Minor UT Acquisition, it will pick up the change.

If a Data Collection Poll (which runs every 2 hours) and then a Minor UT Acquisition is run, it will pick up the change.

Finally, are there any issues (DB corruption) with a data collection job and UT aquisition job running at the same time?

The Data Collection poll will not detect this change, but the others will.

LMS 3.0 will include a feature called Dynamic User Tracking that will rely on MAC notification traps to automatically detect changes like this in the network.

There are no data corruption issues with running a DC and UT acquisition at the same time, but you shouldn't do it. UT relies heavily on DC data, so you may end up performing a useless UT acquisition until Data Collection has had a chance to commit its findings.


Thank you very much for clearing things up.

That feature in LMS 3.0 sounds good. When is that scheduled for release?

Assuming the main requirement for LMS at my client is User Tracking, and knowing that Data Collection is approx 2 hrs 10 minutes, and

Major UT is 1 hr 2 minutes. I see these options (assuming my day starts at 8am).

#1 Run Data Collection at 8am, ends about 10:15, sometime in the next hour a minor UT runs. It could be after 11am before I get any UT data.

#2 Run Major UT at 8am, it finishes at 9:05am. Run Data Collection very infrequently, once or twice a day. Don't even run Minor UT.

Basically it seems to me I'm better served running Major UT every 2 hours at a minimum and running Data Collection very infrequently.

Does this make sense?

thanks again

LMS 3.0 is already orderable, and will start shipping at the end of the month.

Option 2 sounds like the way to go. If the network topology is stable, you do not need to run Data Collection very frequently.
