chetanmeh opened a new pull request #4688: Cosmosdb query metrics for activation poll query
URL: https://github.com/apache/openwhisk/pull/4688
To move forward with activation poll uqery optimization for CosmosDB (#4684) we need to collect some mertics. This PR collects 2 such metrics
## Description
This PR adds 2 new metrics which are computed for the activation list query used in `wsk activation poll` command
1. `histogram_cosmosdb_query_resultDelta_seconds` - Records the time delta between current time and the `start` time of the last activation entry in returned list of activations. This helps in determining how much recent activation results are being returned to end users for the poll command
2. `histogram_cosmosdb_query_sinceDelta_seconds` - Records the time delta between current time and the `since` time specified in list query used by activation poll
Below are the stats as recorded for Prometheus
