Question

what is elastic lag .​

Answer 1

Additionally, we will show how to use the script processor to calculate the ingest lag.

This lag is the difference between the timestamp of when an event has occurred on a remote/monitored system versus the time that the corresponding document arrives at an Elasticsearch cluster.

This can be used for ensuring that the ingest process is not taking too long, and for detecting if remote timestamps are set incorrectly.
