What Interval since the last push metric reports?
DX O2 SaaS
The metrics shown under "Ingestion Metrics" are the "Interval since Last Push" for entities, alarms, metrics, logs.
A value of 0 means that no interval is missing, i.e. you received data all the time - which is the desired state. If the "Interval since Last Push" is greater than 0, then you have not received any data for n intervals. That means a connection or the source system is down. How much data is ingested is shown under "Volume Metrics". If those are 0 then you do not get any data.
