New Log Entry Telemetry not working

tamils · June 25, 2019, 1:41am

Hi,

I added the sample log entry (log-entry.yaml)

It says the instances and handlers created correctly.I run the service endpoints a couple of times and see nothing in the logs.Same with the metrics too.

Any help please.

What was your YAML? And what version of Istio (looks like 1.2)?

I just followed the Collecting Logs task and was able to generate logs without issue (using an existing 1.2 cluster and the bookinfo sample app):

$ kubectl apply -f https://raw.githubusercontent.com/istio/istio/release-1.2/samples/bookinfo/telemetry/log-entry.yaml
...

$ curl http://<my gateway ip addr>/productpage
...

$ kubectl -n istio-control logs <istio-telemtry-pod> mixer

Hi Douglas,

Thanks.

1.2.0 is the version.

Yaml content below.Unable to post as text content.

I have deployed a HTTP server app in a container and has injection enabled and sidecar config ok.Am not using the BookingInfo app here.

Thanks,
Saravana

Saravana,

Did you perhaps install with a different configDefaultNamespace (should be istio-system to match your config), or maybe accidentally checked the logs for istio-policy instead of istio-telemetry?

I took your exact config and was able to generate:

...
{"level":"warn","time":"2019-06-26T17:05:19.555408Z","instance":"newlog1.instance.istio-system","latency":"12.936609ms","responseCode":200,"responseSize":5}
{"level":"warn","time":"2019-06-26T17:05:19.577334Z","instance":"newlog1.instance.istio-system","latency":"9.893999ms","responseCode":200,"responseSize":5}
{"level":"warn","time":"2019-06-26T17:05:19.586200Z","instance":"newlog1.instance.istio-system","latency":"8.770721ms","responseCode":200,"responseSize":5}
...

To further confirm, I went and made sure I was running with a 1.2.X release:

$ kubectl -n istio-system describe deploy istio-telemetry | grep Image | grep mixer
    Image:       istio/mixer:1.2.1

If you believe that everything is setup correctly and you are looking in the right place, I suggest checking some of the mixer self-monitoring metrics to ensure that there aren’t other errors.

Thanks Douglas,

I am checking the right logs.

kubectl logs istio-telemetry-848cd7967-b9tqw -n istio-system mixer | grep newlog1

Do you mean I installed my own HTTP server app with a default namespace? Yes I have not used any custom namespace for the app itself.However istio is installed under istio-system.

The self monitoring metrics show zero count for errors for mixer.

Thanks,
Saravana

Hi Douglas,

Any further setting I need to check.ShouldI configure Ingress GW and then only logs will be captured?

Thanks,
Saravana
