I am looking to identify the time elapsed since the last measurement was recorded for a specific series.
We have a server poll response information added to Influxdb, I am looking to display (query via Grafana), time since last poll response.
Appreciate any suggestion on this query. The poll response time (in seconds) is a field in the measurement.
select poll_resp_time from myseries order by desc limit 1 name: myseries time poll_resp_time ---- -------------- 1492785395626340000 1492785395
