How to increase persistent volume for clickhouse in kubernetes. by default the volume is 20GB. Running the command would not directly increase the volume. I restarted the clickhouse pod as well.

helm -n platform upgrade my-release signoz/signoz \
  --set clickhouseOperator.storage=25Gi

@Srikanth Chekuri @Prashant Shahi @Ankit Nayan I created another django application which use

FROM tensorflow/tensorflow:2.4.0

,this include python 3.6, when the application startup , I got this message

You are using Python 3.6. This version does not support timestamps with nanosecond precision and the OpenTelemetry SDK will use millisecond precision instead. Please refer to PEP 564 for more information. Please upgrade to Python 3.7 or newer to use nanosecond precision.

you can see there is GET has been sent but Signoz can't retrieve any information. is this python issue cause of telemetry data can' t be sent to signoz-otel-collector which cause of Signoz not showing the data correctly.

Hey all, do you support C++ apps?

Is there an ETA for support of log collection?

Hi all, is there any way to integrate Krakend with Signoz?

Hi, is it normal that every time i open the signoz dashboard i have to "sign-up" again?

hi ! Couple questions that I didn't find in the FAQ section. • Is it so that Clickhouse is the only storage backend supported ? and optionally attach it to an AWS S3 storage service ? • Will you support SSO at some point ? until then, what do you suggest to provide UI access to less privileged users than I ? Thank you,

Does anyone can create an admin account via /signup url after the first admin account was created?

or is there a way to disable signup route and only allow "invite"?

Hello team I tried setting retention period for metrics and traces to 15 days on UI [https://signoz.io/docs/userguide/retention-period/] but it gets removed when I go back to the settings. Is there a way to confirm the current retention settings as it is not being shown up on UI? Plus I am not seeing move to s3 option on UI. I am on 0.7.5

After

helm repo update

1. When I check with

helm search repo signoz --versions

I am getting latest version as 0.7.5 but on my UI, It is suggesting me to move to 0.8.0 but I am not able to see that in the list

@Hima Vyas After upgrading don't forget to run the migration steps to retain old data. Join #k8s_operator_helm channel to stay up to date with kubernetes releases and instructions.

Hi, We are facing some issues while trying to use network_mode: host docker-compose file has multiple interdependent services We're getting error due to clickhouse services on which other services are dependent. Like query service is unable to connect to some internal db and throwing error clickhouseReader/reader.go:90 error connecting to primary db: dial tcp: lookup clickhouse on 127.0.0.5353 server misbehaving We checked clickhouse service logs and it says address already in use. <Warning> Application: Listen [0.0.0.0]:9009 failed: Poco::Exception. Code: 1000, e.code() = 98, Net Exception: Address already in use: 0.0.0.0:9009 (version 21.12.3.32 (official build)) Similarly for 8123 and 9009, but we checked that these ports are being used by the given service itself.

Hi #support, I have updated to 0.8.0 and I created an account with my email and password. when I checked the settings, I was given admin access. After I logged out, I am trying to login back with the same password and it's saying invalid credentials. On create account it's saying, you are not allowed to create an account, ask your admin to send an invite link. Is there a way to resolve this as I am blocked and not able to log in?

hi ! What would be the endpoint in case I want to scrape metrics from a Prometheus receiver from a separate Collector such in https://signoz.io/docs/tutorial/kubernetes-infra-metrics/ ? I was able to follow through that one for k8s metrics but now I would like to scrape Prometheus metrics. Thank you,

Hi Team, is there a provision to modify the base path of signoz UI and host it behind nginx at subpath? For instance: instead of https://mydomain.com/ i want https://mydomain/signoz/ since my app is already running at basepath /

Good Morning Team, Is there a way to make the service-map service names more readable?

Hi team I have a query around retention period. For example, I have set up 15 days for metrics and traces but after 7 days I change it to 5. Would the first 2 days of data be deleted? If so, when does it get deleted - a fixed time where this works or as soon as the change is done? This is for the version - V 0.8.0

i have setup kubernetes metrics in signoz, i was creating custom dashboard for kubernetes metrics like container cpu limit for that i used the query available on official site "k8s_container_cpu_limit" but in that i cannot see which container is taking how much cpu limit, can anyone help me on this.

Mainly am looking for pods cpu lmit and request and pod memory limit and request queries.

I am trying to upgrade from an older version to v8.0 my deployment used docker standalone. I am not quite clear on the documentation instructions. v8.0 upgrade is going to break things and I need to perform data migration. The instructions go like this (https://signoz.io/docs/operate/upgrade/):

First upgrade to 0.8.0
Follow the platform specific instructions to upgrade to 0.8.0 and above.

Note that the past data will not be visible on the new application until you run the migration script.

Docker
- git clone -b main <https://github.com/SigNoz/signoz.git> && cd signoz/deploy/
- git checkout v0.8.0
- ./install.sh

Steps to run migration script:
Docker
docker run --name signoz_migrate --network clickhouse-setup_default \
  -it -d signoz/migrate:0.8 -host=clickhouse -port=9000
Steps to check logs:

docker logs -f signoz_migrate
In case of failure and have to run again, make sure to cleanup the container before running the migration script again.

docker stop signoz_migrate

docker rm signoz_migrate

My question is, what is the first thing to do? • I have signoz v6 running • I want to preserve the historical data I have • I already have the repo (I could just git pull for new changes and checkout the v8.0) • Should I stop the running docker-compose first before I clone? • Will the over-written changes to the repo erase my data? I know these could be newbies question but I would appreciate the clarity so I can do this successfully

Ok, solved two problems i had but seems my tracing doesnt work as expected. i have a API that gets called via normal http request and then works internal with gRPC. Is a mix of REST / gRPC not tracable?

Hello Team, Recently i have updated my signoz image from 0.7.5 to 0.8.0 and queryservice image from 0.7.5 to 0.8.0 after that i tried to redeploy few services from my project but it is not showing under traces section of signoz UI previously it was used to show.

I got below logs from queryservice pods: 2022-05-13T060516.645Z DEBUG clickhouseReader/reader.go:1137 Error in processing sql query: code: 81, message: Database signoz_traces doesn't exist 2022-05-13T060516.645Z ERROR app/http_handler.go:1618 HTTP handler, Internal Server Error{error 26 0 Error in processing sql query} go.signoz.io/query-service/app.(*APIHandler).handleError /go/src/github.com/signoz/signoz/pkg/query-service/app/http_handler.go:1618 go.signoz.io/query-service/app.(*APIHandler).getServices /go/src/github.com/signoz/signoz/pkg/query-service/app/http_handler.go:957 go.signoz.io/query-service/app.ViewAccess.func1 /go/src/github.com/signoz/signoz/pkg/query-service/app/http_handler.go:212 net/http.HandlerFunc.ServeHTTP /usr/local/go/src/net/http/server.go:2047 go.signoz.io/query-service/app.loggingMiddleware.func1 /go/src/github.com/signoz/signoz/pkg/query-service/app/server.go:156 net/http.HandlerFunc.ServeHTTP /usr/local/go/src/net/http/server.go:2047 go.signoz.io/query-service/app.(*Server).analyticsMiddleware.func1 /go/src/github.com/signoz/signoz/pkg/query-service/app/server.go:172 net/http.HandlerFunc.ServeHTTP /usr/local/go/src/net/http/server.go:2047 go.signoz.io/query-service/app.setTimeoutMiddleware.func1 /go/src/github.com/signoz/signoz/pkg/query-service/app/server.go:182 net/http.HandlerFunc.ServeHTTP /usr/local/go/src/net/http/server.go:2047 github.com/gorilla/mux.(*Router).ServeHTTP /go/pkg/mod/github.com/gorilla/mux@v1.8.0/mux.go:210 github.com/rs/cors.(*Cors).Handler.func1 /go/pkg/mod/github.com/rs/cors@v1.7.0/cors.go:219 net/http.HandlerFunc.ServeHTTP /usr/local/go/src/net/http/server.go:2047 github.com/gorilla/handlers.CompressHandlerLevel.func1 /go/pkg/mod/github.com/gorilla/handlers@v1.5.1/compress.go:141 net/http.HandlerFunc.ServeHTTP /usr/local/go/src/net/http/server.go:2047 net/http.serverHandler.ServeHTTP /usr/local/go/src/net/http/server.go:2879 net/http.(*conn).serve /usr/local/go/src/net/http/server.go:1930

Has anyone an idea how to pass the tracing context from golang otelgin middleware to grpc? Because my gRPC tracing now works flawless but the REST Request is still disconnected from the gRPC tracing context?

Hi there, I'm trying to understand how this works: https://signoz.io/docs/userguide/metrics/#steps-to-add-resource-attributes I added the OTEL_RESOURCE_ATTRIBUTES environmental variable to my startup script, as well as to the Kubernetes Deployment environment variables Not seeing any filters on the front-end:

Hello, I think it's very stupid but I block on the exporter. In my application is move from grpc to http in https://github.com/SigNoz/sample-django/blob/main/gunicorn.config.py#L2 And move from 4317 to 4318, but no more traces. I've try with and without

/

but library handle it for trace https://github.com/open-telemetry/opentelemetry-python/blob/v1.11.1/exporter/opent[…]entelemetry/exporter/otlp/proto/http/trace_exporter/__init__.py Any clue

Hi, What is the current version of OpenTelemetry which is deployed with Signoz ?

Does the default signoz chart has to be extended to use one of these instrumentations? https://github.com/open-telemetry/opentelemetry-go-contrib/tree/main/instrumentation

or do they work out of the box like traces?
