Web Server Monitoring Dashboard: Requests Average Duration Query error #438
Description
Description
In the default web dashboard, the underlying query fails with:
External error: Execution error: Cannot convert Duration(Microsecond) to epoch
I looked at the underlying query - it looks like valid postgres syntax to me but it is not running.
WITH dataset AS (
SELECT
(attributes->>'http.method') || ' ' || COALESCE(attributes->>'http.route', attributes->>'http.target') as endpoint,
extract(epoch from end_timestamp - start_timestamp) * 1000 as duration_ms
FROM records
WHERE attributes ? 'http.method' and (attributes ? 'http.route' or attributes ? 'http.target')
)
SELECT endpoint, avg(duration_ms) as average_duration_ms
FROM dataset
GROUP BY endpoint
ORDER BY average_duration_ms desc
LIMIT 7;
Important line is extract(epoch from end_timestamp - start_timestamp) * 1000 as duration_ms
