Hi. I have trouble with auto refresh UI. How can I enable auto refresh? Many thanks!

Hi team, Happy morning I'm currently implementing signoz in GCP via helm but my pod getting "CrashLoopBackOff" FYKI: chi-signoz-cluster-0-0-0 1/1 Running 0 21h clickhouse-operator-57959d7fd8-tpl5g 2/2 Running 0 21h my-release-signoz-alertmanager-0 0/1 Init:0/1 0 23h my-release-signoz-frontend-6dd9f97bc4-jnkkb 0/1 Init:0/1 0 23h my-release-signoz-frontend-786b84f4fd-lqd2f 0/1 Init:0/1 0 21h my-release-signoz-otel-collector-6b47dd5b45-m9v7d 0/1 CrashLoopBackOff 282 (2m10s ago) 23h my-release-signoz-otel-collector-7587cb94c5-s46jg 0/1 CrashLoopBackOff 261 (117s ago) 21h my-release-signoz-otel-collector-metrics-55644664d9-qdcpj 0/1 CrashLoopBackOff 243 (4m40s ago) 21h my-release-signoz-query-service-0 0/1 CrashLoopBackOff 293 (3m29s ago) 23h my-release-zookeeper-0 1/1 Running 0 23h This is error logs : Logs: runtime.main /usr/local/go/src/runtime/proc.go:255 2022-10-18T064747.649Z INFO app/server.go:112 Using ClickHouse as datastore ... 2022-10-18T064747.654Z ERROR clickhouseReader/reader.go:108 error connecting to primary db: code: 516, message: admin: Authentication failed: password is incorrect or there is no user with such name go.signoz.io/query-service/app/clickhouseReader.NewReader /go/src/github.com/signoz/signoz/pkg/query-service/app/clickhouseReader/reader.go:108 go.signoz.io/query-service/app.(*Server).createHTTPServer /go/src/github.com/signoz/signoz/pkg/query-service/app/server.go:113 go.signoz.io/query-service/app.NewServer /go/src/github.com/signoz/signoz/pkg/query-service/app/server.go:87 main.main /go/src/github.com/signoz/signoz/pkg/query-service/main.go:53 runtime.main /usr/local/go/src/runtime/proc.go:255

Hi I'm trying to use Opentelemetry-python to auto-instrument my Django app and I'm using signoz as backend. But on the signoz UI there are only parent traces shown and there are no child spans and I think there should be one. Please help me with that. If I need to share more information then you can ask me.

Hi Team, I am facing issue to setup Signoz on local k8s system. Should we create pv and pvc before deploy it on local k8s system?

Hi I'm trying to send open telemetry data to signoz. I have added host details for outputs.opentelemetry and I can from telegraf side messages are being pushed. But I can't see Serive/messages in Signoz . Can any one help here.

Hi Team, I'm trying to setup Signoz using the official docker installation method. I was able to get the service up and running but failing to instrument my

GraphQL

application. I believe this is happening because of the way my host is set up. It's a VM with docker + nginx proxy manager. What should be the value for

OTEL_EXPORTER_OTLP_ENDPOINT

in this case?

Hi, I wanted to filter out some log entries since Longhorn is running in debug mode it fills up the logs very quick. But I found no good way of doing it. How should I configure the signoz opentel collector pipe for it? If I try to reges the body via filter I get an error message. Here is what I want to filter out and the error message:

How can I send nginx access and error logs to Signoz directly?

Hello everyone, I tried to install the Signoz into my Go application, already follow the instructions from the doc but when I try to hit the request to generate the service, there is no service generated into my dashboard, anyone know what happen?

Maybe there's something that I miss prolly?

is anyone try logs in Kubernetes?

@Apoorva can i see how you try it?

I am trying to install SigNoz on Kubernetes (self-hosted cluster). I see that the Helm charts have created 4 PersistentVolumeClaims which are all in Pending state. The documentation does not seem to provide any information about if (and how) I should create the volumes it needs. Can anyone point me in the right direction?

Hi, I am trying to setup Signoz on a clean Ubuntu 22.04 VM, 6gb of ram, 50gb storage, runniing sudo ./install gets the following error:

I figure this must be something really basic, I tried a debian VM to see if it made a difference but getting the same result. Any help much appreciated.

hi, I am new in the community, and thanks for the nice APM, I have a question, do you know the reason the names of apps at Map Services is not display completly? Signoz v v0.11.2 Regards.

Hi SigNoz, we’re excited to try out your platform! We have a FastAPI service where we are logging with structlog. Is there an easy way to connect these logs to SigNoz?

Out of the boz the celery instrumentation doesn't seem to give number of tasks picked up etc. How to add those?

Hi, regarding the environment variables

OTEL_EXPORTER_OTLP_ENDPOINT=127.0.0.1:4317 \

OTEL_RESOURCE_ATTRIBUTES=service.name=graphql-service

Can we set these inside of the code somehow instead of in the terminal? For example inside the config object of

OTLPTraceExporter

?

Hi, I was testing how the

OTEL_EXPORTER_OTLP_ENDPOINT=127.0.0.1:4317

variable worked, in the guide it says we are suppose to set it locally in the terminal. I tried to set it as a different port and see if signoz can still detect data coming from my graphql server. I was expecting it to break (not detect the service) but it was still able to detect, why is this? Is it overriding the incorrect port I set in the terminal and using some kind of default value? Thanks.
