Request metrics for Graphite

Gatling (Open-Source)
1

Hello everyone,

I’m testing gatling with influxdb.
As in the doc
http://gatling.io/docs/2.0.0-RC2/graphite/index.html?highlight=metrics

Request metrics

Requests metrics give you, for each request (or all requests using allRequests) and by status (OK, KO and both) :

  • count : requests/sec
  • min and max : Min and Max response time for the request
  • percentilesXX : First and second percentiles, as defined in gatling.conf (defaults are 95th and 99th percentiles)

I have max and min response time for my request.

But when I check all value in influxdb, for the same timestamp, the max value is smaller than the min value. Is it normal? Thanks for your help!

Ex:

gatling.xxx.test.ok.max

time | value |

  • | - |
    2016-04-07T15:45:53Z
    | 4640 |

gatling.xxx.test.ok.min

time value

2016-04-07T15:45:53Z
4656

This shouldn’t be the case. I am using the 2.2.0-SNAPSHOT and here is a snippet from my Gatling measurement: https://github.com/bbc/notes-on-perf-testing/blob/master/ch/gatling/real_time_graphs.md#verification.

To debug, point your graphite host to localhost in your gatling.conf and ‘nc -l 2003’
