Reports FAQs and Troubleshooting
Symptom The Top N Busiest Clients report and the Client Statistics report display 0 (zero) values.
Possible Cause Wireless client polling frequency is set to 51 minutes by default. The counters could
reset between two polling cycles which would cause zero values when the reports are run.
Recommended Action Increase the polling frequency by selecting Devices > Discover > Inventory >
Polling.
Caution Increasing the polling frequency could have an effect on performance.
Symptom The client association data in the Group Client Association report differs from the data shown
in the Current Client Associations report.
Possible Cause The data for the Group Client Association report is collected using performance
attributes polling and the data shown in the Current Client Association report uses wireless client
polling.
Whichever report has a higher polling frequency will contain the most up to date data. Select
Devices > Discover > Inventory > Polling to view polling frequency.
Recommended Action None.
Symptom The access point data in the Historical Associations report is not accurate.
Possible Cause The wireless client was associated with an access point managed by the WLSE, but
subsequently associated with an access point that was added to the network, but not yet managed by
the WLSE.
Recommended Action Verify that the associated access points are in the managed devices folder by
selecting Devices > Discover > Managed Devices > Manage/Unmanage.
Symptom The Summary and/or Detailed report for access points is empty.
Possible Cause The SNMP user may not have the correct rights assigned.
Recommended Action
a.
Open a browser window to the access point, and select Setup > Security > User Information.
b. Make sure that the user corresponding to the SNMP community (which is set up in WLSE in
Discovery > Device Credentials) has been granted rights for the following: Ident, firmware,
admin, snmp, and write.
c. If not, click on the user and assign all these rights.
Symptom The group report for a user-defined group contains no data.
Possible Cause Reports cannot be displayed for a user-defined group that contains another group.
Recommended Action Display individual reports for the sub-groups or devices within the
user-defined group.
