Does the following message in the bzt.log file affect a performance test:
[2021-05-12 00:13:36,851 INFO Engine.cloud-utils] Failed long polling request (sleep 1): API call error https://<blazemeter URL>/api/v4/taurus/r-v4-<sessionID>/poll: 503 Service Unavailable
<blazemeter URL> is a.blazemeter.com for public cloud accounts and the account specific URL for Private Cloud locations (ex my.private.blazemeter.net:8443. This is the site hosting the BlazeMeter account and test reports.
Release : SAAS
Component : BLAZEMETER GENERAL PLATFORM ISSUE
For the most part, this error is a benign error (as it is reported as an INFO message not ERROR message in the log).
This just occurs when the engine checks if to see if it can reach the <blazemeter URL> to report data that was gathered during that instance. It will always retry if it fails, so eventually all the report data is retrieved as expected.
