Subject [GitHub] [jmeter] dgetzlaf opened a new pull request #645: Add escaping for new lines in AbstractInfluxdbMetricsSender
Date Thu, 25 Feb 2021 10:42:04 GMT

dgetzlaf opened a new pull request #645:

   ## Description
   Add escaping for new lines in AbstractInfluxdbMetricsSender.tagToStringValue()
   ## Motivation and Context
   For load- and performance testing (distributed testing) we send metrics to the InfluxDB.
   From time to time, no metrics occur in the dashboard while testing:
   ![Missing metrics](
   In the log file of the JMeter controller, I find this line pretty often:
   ERROR o.a.j.v.b.i.HttpMetricsSender: Error writing metrics to influxDB Url: https://<URL>,
responseCode: 400, responseBody: {"code":"invalid","message":"unable to parse 'jmeter,application=<application

   It seems that the escaping of the line breaks is not working properly. By that, invalid
requests are sent to the InfluxDB, resulting in 'missing fields'.
   ## How Has This Been Tested?
   1. Configure InfluxDB connection
   2. Add a new JSR223 with the body
   throw new Exception('''Line 0
   Line 1
   Line 2
   Current JMeter 5.4.1 Release:
   3. Looking at the console output / jmeter log file --> The error occurs
   4. influxDB : No metrics received
   JMeter 5.4.1 Release + this fix:
   3. Looking at the console output / jmeter log file --> No error occurs
   4. influxDB : metrics are received
