Fixed In:
13.0.0 HF1

Opened: Jan 29, 2017
Severity: 3-Major

Symptoms

There are two collection intervals in AVR for collecting data: one every 10 sec for real time display and one every 5 min (or else set) for general statistics. The 5 min statistics is accumulated from the 30 intervals of 10 seconds. Sometimes, the last 10 seconds interval is missings the 5 min interval accumulation and entered the next 5 min interval resulting in an inaccurate accumulation of the 5 min interval.

Impact

Inaccurate accumulation of the 5 min interval statistics.

Conditions

This happens when the 10 seconds interval is taking too long to write it self

Workaround

No workaround, some statistics will leak to next interval.

Fix Information

The statistics for every 5 min interval will be display correctly (no leak between adjacent intervals).
