Istio missing metrics

I am testing Istio 1.1, but the collection of metrics is not working correctly.

I can not find what the problem is. I followed this tutorial and I was able to verify all the steps without problems.

If I access prometheus I can see the log of some requests. enter image description here

On the other hand, if I access Jaeger, I can not see any service (only 1 from Istio) enter image description here

Grafana is also having some strange behavior, most of the graphs do not show data.

Solution

  • In istio 1.1, the default sampling rate is 1%, so you need to send at least 100 requests before the first trace is visible.

    This can be configured through the pilot.traceSampling option.
