Hi Team, I’ve been experimenting with Signoz for quite a while, and hats-off to an amazing product. I have 2 things that i needed help with - 1. Is there a way to provide headers in monitoring http endpoints? One of the endpoints that I want to monitor requires an authorisation header. 2. I am constantly seeing these errors in my otel-collector logs. Is this concerning? Can these be disabled somehow so I don’t miss the important logs?

Hey everyone, I have 5 services built with ExpressJS running out of Amazon ECS in a Fargate cluster Is there anyway to export logs from those services directly to SigNoz, since it is fargate and we technically don’t have access to the “host” I figured there is no way for the same since log collectors generally scrape logs from the

docker logs

of a container Any ideas on how this could be done?

Hi, Just a quick confirmation, I noticed in the official docs here : https://signoz.io/blog/opentelemetry-nestjs/

Copy code

sdk
  .start()
  .then(() => console.log('Tracing initialized'))
  .catch((error) => console.log('Error initializing tracing', error));

here we have setup a file called

tracer.ts

where the SDK is

start()

later in the main file we are again calling

tracer.start()

why is that ?

Hi! Can somebody suggest, when

opentelemetry-instrumentation-fastapi

might be able to support latest fastapi version?

Hi, is it possible to use my own alertmanager instead of using the one coming with the helm chart? My current W/A is to set replica count to 0 but I don’t like it 🙂

Signoz is not capturing the span.kind attribute. I checked the same Opentelemetry trace in New Relic and see it there. Can this be added?

Hi, In the logs section for Signoz, I can see the logs from Signoz as well, is it possible to disable them ?

Timothy Wigginton

03/02/2023, 3:37 PM

Hey I was wondering why there is a difference between traces coming from dynamoDB. One uses python and the other uses go but they both use official AWS instrumentation. It seems go stores the operation in aws.operation and python stores the operation in rpc.method. I know the attributes are not set by SigNoz but maybe aws.operation should be read similar to rpc.method?

Is there a way to create a new clickhouse user with read only access via the helm chart override values?

On what basis are the spans colored? My java application is autoinstrumented and mades JDBC calls. However all the spans appear blue. I’d like for the spans with attribute db.system=mssql to be colored differently. How can I do this?

The log message of my logs ingested in SigNoz are in the field “body” when I examine the full content. However the “body” field is not listed as one of the “Interesting Fields” so I’m unable to add it to the table view of logs.

hi team, i am new into signoz, i have followed tutorial how to run signoz using docker and simple app • https://signoz.io/docs/install/docker/ • https://github.com/SigNoz/sample-golang-app but i have some trouble, i've got these error everytime i hit the endpoint:

Copy code

max retry time elapsed: rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing dial tcp: missing address"

and

Copy code

context deadline exceeded

also in the interface i got message

something went wrong

(pict) this is my

.env

except database connection:

Copy code

SERVICE_NAME=goApp
INSECURE_MODE=true
OTEL_EXPORTER_OTLP_ENDPOINT=localhost:4317

is there something i miss? ps: i ran in windows machine (maybe i got these errors because i ran in windows machine since it's not officially supported?) thanks in advance!

i'm trying to forward every exception signoiz receives from my rails app to my mattermost instance via webhooks. i've set up the alert channel, and now should set up an alert query. i started via alerts > new alert > exceptions-based alert. i only have the option of clickhouse query. QueryBuilder is greyed out, PromQL is not an option at all (was mentioned in the docs) i'm baffled by what to do next. i understand that i need to query clickhouse in order to trigger the alert, but i kind of want an all-forward rule. could anybody help me on how to go about doing that?

I want to monitor my application in aws ecs fargate is it possible to attach a signoz otel collector to every service as a sidecar or should I have multiple otel collectors as sidecars and have them forward all their data to a single signoz otel collector instance?

Greetings Everyone, Kindly I want to ask few questions: 1- Is there a way to create/register the first admin user of signoz (first time login from UI) using signoz helm chart ? 2- Is there a way to import signoz dashboards from helm chart. 3- Is there a way to modify the retention period for metrics, logs and traces from helm chart ? We are trying to automate these things in order to deploy on multiple clusters. Thanks in advance 🙏
