IV12694: HISTORICAL BASELINE DATE SELECTED DOES NOT MATCH RESULTING DATE DISPLAYED

IBM Tivoli Monitoring 6.2.2 Fix Pack 9 (6.2.2-TIV-ITM-FP0009)

APAR status

• Closed as program error.

Error description

• When a user attempts to display a Historical Baseline in a TEP
  chart, the displayed data does not match the selected date.
  
  Steps to reproduce:
  1.  Select a few days worth of historical data in the TEP
  client. It is important to not use today's date.  Choose
  yesterday or a day before.
  2.  Add a Historical Baseline.
  3.  Mouse-over the data for the Historical Baseline and notice
  that it isn't the date from Step 2.
  
  Problem has been observed in 622 and 623 releases.
  

Local fix

Problem summary

• Data for the wrong date is shown if a historical baseline is set
  for a plot chart with a historical timespan ending prior to the
  current day.
  
  
  If a plot chart is configured for a timespan ending prior to the
  current day and a historical baseline is set for a specific or
  relative date, the baseline data for a different date will be
  shown. The date in the flyover for the baseline points correctly
  shows the date of the data. The date in the legend matches the
  date requested but does not match the data shown.
  Although it is not a change in behavior resulting from the fix,
  please note that the historical baseline date must be before the
  chart end date. If it is the same or later, no baseline will be
  drawn and an error message will appear in the log but there will
  be no on-screen message. Because of this restriction for plot
  charts ending before the current date, the historical baseline
  dialog option to show yesterday's data will never draw a
  baseline. The options to show last week's data or data for the
  last n days will not draw a baseline for any dates on or later
  than the chart end date.
  

Problem conclusion

• The logic was changed to correctly calculate the date for the
  historical baseline regardless of whether or not the chart end
  date matches the current date.
  
  The fix for this APAR is contained in the following maintenance
  packages:
    | fix pack | 6.2.2-TIV-ITM-FP0009
    | fix pack | 6.2.3-TIV-ITM-FP0002
  

Temporary fix

• Do not set a historical baseline for a plot chart unless its
  timespan ends on the current date.
