Sudden Drop of Active Sessions in Monitoring Tool During Manual Rolling Upgrade (Doc ID 2585333.1)

Last updated on SEPTEMBER 11, 2019

Goal

During the first rolling upgrade with traffic, which is performed during the early morning so as to minimize the possible impact, the monitoring dashboard reported a sudden drop in active Gy sessions, as well as the total rated event cache. However, in the next reading, it returned to a similar value before the fall. This happened several times throughout the rolling upgrade.

You can see the image of the ECE Sudden Session Drop here.

What would be the cause of this behavior? Is it something to expect in future rolling upgrades with traffic?
