InfluxDB integration with multiple load agents

[besessener]

Let's say I am running K6, the very same script, on multiple load agents at the same time. Is there a way to collect the influxDB measurements of all agents, aggregate it to one so that in Grafana I am able to see the real number of VUs for example?

I guess the problem you are seeing (as you haven't said whether you tried it or not) is that some metrics (Gauge) are getting only the values of one of the load generators.

This is as k6 doesn't automatically set additional tags (as it doesn't know what htey should be) so that samples from different laod generators can be identified.

You can add --tag generator=2 with different values (and tag name for that matter) so you that influxdb doesn't aggregate them and you can query them all. You likely will need to change some of the dashboards as well.

Hope this helps you!

i did not try it out. I was curious if the aggregation would happen all by itself. I though i i have 3 paralell jobs sending data, they would override each other instead of summing up.....like 10 users on each parallel, I thought I would only see 10 users in Grafana, not 30.

Hope I understood you right. In that case thank you :)
