APAR status

• Closed as program error.

Error description

• The graphs are set to display labels for every 25 seconds
  worth of data, and if for any reason the system slows and
  the time between each datapoint increases, more and more
  labels get added to the graph and the X axis of the graph
  can become unreadable.

  The AdminCenter graphs are set to display X axis labels for
  every 25 seconds worth of data, and if for any reason the system
  slows and the time between each datapoint increases, more and
  more labels get added to the graph and the X axis of the graph
  can become unreadable.
  

Problem conclusion

• A maximum of 4 X axis labels are displayed in the AdminCenter
  graphs, and rather than using a hardcoded value to set these
  label intervals, we now calculate them using the timestamps of
  the datapoints.
  
  The fix for this APAR is currently targeted for inclusion in fix
  pack 8.5.5.6.  Please refer to the Recommended Updates page for
  delivery information:
  http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
  

Temporary fix

• Refreshing the Browser page will reset the graphs, and the
  labels should start displaying correctly.
