Server backlog Health Indicator has been released on Friday, March 24, 2017. All 7.2.1+ customers connected to CDC will receive this Health Indicator from the cloud.
This Health Indicator monitors the server backlog of file information received from agents. It triggers when excessive server backlog builds up. Normally this health indicator is invisible. When backlog starts growing and is more than 10% of the safe threshold this Health Indicator becomes visible. When backlog goes over the threshold it turns Red.
Temporary spikes because of mass software distribution like Windows updates should not cause this Health Indicator to trigger. These spikes are short lived and subside over a couple of days. This Health Indicator will help track the spikes and assess their impact on the server.
If this Health Indicator triggers please file a support case to investigate it further.
Severity | When |
Invisible | Server backlog history is less than 3 days old or non-existent (The intent of this is to avoid going red during initialization). OR The current backlog size is less than 10% of the calculated threshold below (The intent of this is to hide awkward graphs when the backlog is always low on the x axis and the deployment is safe) |
Red | Calculated Red Threshold = # of Active Agents * Average Cache Size * 10% Final Red Threshold = Min(Calculated Red Threshold, 35000000) ←(The minimum of the calculated threshold and 35,000,000). If the current backlog size is greater than or equal to the Final Red Threshold, this health indicator will display red severity. |
Green | All other cases |
