Hey, I' ve got a JS error on trace detail.. On a similar trace there is arround 2204 Span. Maybe the trace is broken ?

Hello guys, I'm just getting started with SigNoz using Python. After spinning up SigNoz docker image through the

./install

command, I see that the dashboard is already up and running on

<http://localhost:3301/application>

. After configuring the environment variables with this command:

OTEL_RESOURCE_ATTRIBUTES=service.name=Flask_App OTEL_METRICS_EXPORTER=none OTEL_EXPORTER_OTLP_ENDPOINT="<http://localhost:4317>" opentelemetry-instrument python3 app.py

, I don't see I don't see Flask_App is shown on the dashboard. Any idea what I'm doing wrong here?

When i have check the logs of signoz/otelcontribcol container. I am getting

2022-05-25T07:32:08.158Z        warn    zapgrpc/zapgrpc.go:191  [core] grpc: Server.Serve failed to create ServerTransport:  connection error: desc = "transport: http2Server.HandleStreams received bogus greeting from client: \"POST /v1/traces HTTP/1.1\""  {"grpc_log": true}

Internal Server Error - Request ID: 01G4DTGZDHQKC3PYDSJSP1R8KP

I am unable to capture any traces. The UI never shows any activity. I have signoz installed with kubernetes (by helm chart). I've also setup an ingress (with tls cert) to direct to ports 3301 for the UI and 4317 for the collector. The UI works fine opening on https. I also have test opentelemetry clients for .NET Core and python. My problem is that I so far can not see any traces in the UI. As a test, if I wget the collector URL (https://sigznos.api.myserver.local), I can see an error in the collector log, so can confirm the message is getting to the backend (I obviously don't expect it to generate a span). Both client apps are instrumented and I can see the output in the console. For the .NET Core app, the only exporter when I see any activity in the log is ZipkinExporter. Including/excluding this line makes no difference: AppContext.SetSwitch("System.Net.Http.SocketsHttpHandler.Http2UnencryptedSupport", true); Here's my .NET code: static void Main(string[] args) { //AppContext.SetSwitch("System.Net.Http.SocketsHttpHandler.Http2UnencryptedSupport", true); using var tracer2Provider = Sdk.CreateTracerProviderBuilder() .SetResourceBuilder(ResourceBuilder.CreateDefault()) .AddSource("MyTest.Console") .AddAspNetCoreInstrumentation() .SetResourceBuilder(ResourceBuilder.CreateDefault() .AddTelemetrySdk()) .AddZipkinExporter(otlpOptions => { otlpOptions.Endpoint = new Uri("https://signoz.api.myserver.local"); otlpOptions.ExportProcessorType = ExportProcessorType.Simple; }) .AddConsoleExporter() .Build(); using (Activity activity = source.StartActivity("RunProgram")) { activity?.AddTag("CMA-app-Name", "MyTest.App.Name"); var program = new Program(); program.SigNozTest(); // Makes an http call to an API } Here's the output on the console: Activity.TraceId: 14d3c904ec9ee6583014177882f9f590 Activity.SpanId: 9603d4cf46d8c592 Activity.TraceFlags: Recorded Activity.ActivitySourceName: MyTest.Console Activity.DisplayName: RunProgram Activity.Kind: Internal Activity.StartTime: 2022-06-01T00:40:43.5888893Z Activity.Duration: 00:00:01.4237944 Activity.Tags: CMA-app-Name: MyTest.App.Name Resource associated with Activity: telemetry.sdk.name: opentelemetry telemetry.sdk.language: dotnet telemetry.sdk.version: 1.3.0.498 service.name: MYTEST application: MYTEST The .NET app (code and trace above) generates this error in the collector log: 2022-05-31T23:03:51.352Z warn zapgrpc/zapgrpc.go:191 [core] grpc: Server.Serve failed to create ServerTransport: connection error: desc = "transport: http2Server.HandleStreams received bogus greeting from client: \"POST / HTTP/1.1\\r\\nHost: s\"" {"grpc_log": true} The python client app shows no sign of connecting to the backend. It's the sample flask app from https://signoz.io/blog/opentelemetry-flask/ with the following env vars set: OTEL_EXPORTER_OTLP_ENDPOINT="https://signoz.api.myserver.local" OTEL_EXPORTER_OTLP_INSECURE=true OTEL_RESOURCE_ATTRIBUTES=service.name=my-flask-app I've also tried setting OTEL_EXPORTER_OTLP_CERTIFICATE to the value of the cert. The message I get on the flask console is: Transient error StatusCode.UNAVAILABLE encountered while exporting span batch, retrying in 2s. What am I missing?

Hi guys, am facing some issues here: • Alerts stopped working after the latest update v0.8.0 • Move data to S3, for both metrics and traces, is not working (when you define a period, it's takes so long loading, and then when you refresh the page, nothing saved) • gRPC status and method in the trace table are still not displayed correctly. even though it's mentioned as fixed in the latest release v0.8.0 Am I doing it wrong? 🤔

Hello everyone, I am running into a little bit of trouble with this on PHP. I have followed the example provided here https://signoz.io/docs/instrumentation/php/#instrumenting-a-sample-php-application-with-opentelemetry, but getting some PHP errors with it.

use GuzzleHttp\Client;
use GuzzleHttp\Psr7\HttpFactory;
use OpenTelemetry\Contrib\OtlpHttp\Exporter as OTLPExporter;
use OpenTelemetry\SDK\Common\Attribute\Attributes;
use OpenTelemetry\SDK\Trace\SpanProcessor\SimpleSpanProcessor;
use OpenTelemetry\SDK\Trace\TracerProvider;

...

$exporter = new OTLPExporter(
   new Client(),
   new HttpFactory(),
   new HttpFactory()
);

$tracerProvider =  new TracerProvider(
   new SimpleSpanProcessor(
      $exporter
   )
);

Error: Trying to access array offset on value of type bool in /vendor/open-telemetry/opentelemetry/src/SDK/Resource/Detectors/Process.php:31 Seems to be thrown when creating a new TracerProvider. None of my data is getting sent to Signoz, though I've run the troubleshooting steps of printing out the telemetry data and also running the test to see if my docker container can hit signoz, both worked as expected.

is there an example expression to use with alerts that counts exceptions?

hi I tried to do Java OpenTelemetry Instrumentation over k8 pod to get metrics but it's giving above logs

Hey guys, am facing a hard time defining the clubhouse pvc resizable. (using latest helm chart) config:

pvc. any idea?

Hello, I'm new to signoz and I am currently testing it to collect traces from java backend using the opentelemetry java agent. As a proof of concept it works well. However I couldn't find anything explaining how the receiver authentication work. Is it just unsecure and open or am I missing something ? Currently it seems that anything without authentication can send trace data to signoz receiver. I tried to inspire from the example documented in this section but the agent seem to completely ignore the config https://opentelemetry.io/docs/collector/configuration/#authentication Is there a complete step by step guide on how to properly configure authentication betwen the java agent and signoz ?

Hi, I have deployed SigNoz as a part of my docker env and want to monitor a kubernetes cluster and application over it is there any way i can do that?

and documentation will help…

sorry for the dumb question i am trying SigNoz for the first time…

Hello Team, i was looking to deploy mongodb-exporter as k8s pod and svc i got the link but it has installation with docker-compose file (https://signoz.io/blog/opentelemetry-mongodb/) can anyone help me to deploy mongodb exporter in kubernetes types.

Hi Team, I have a doubt regarding the service name I was trying to monitor a node application with opentelemetry and signoz and it was doing fine. The only problem was it's not getting the service name resource attribute and the service is being shown as "unknown_service:node" in the dashboard. I have tried to provide the service name using semantic attributes in opentelemetry node sdk. Thanks for you time.

Hey SigNoz Team, I've a question about spans an correlation-ids. In our infrastructure a middleware generates a correlation-id with the first request. This correlation-id is the same for all further internal reuests (http and message-broker/rabbitmq). So if an error occured, we can track it down to that correlation id. Is it possible to aggregate a span in a way, that it contains everything that belongs to one correlation-id? E.g. we make a request from /auth/register to /internal/auth/register-company and the second endpoints throws an error, that the span contains the entire call-trace?

Thank you very much 🙂

Hi, When the OTEL collector is stopped due to some reason, the APIs which are emitting the traces to the collector start throwing the connection error. This error will not disappear even after restarting the collector. This requires the APIs to be restarted. This becomes a limitation. What is the solution for this ?

Hey SigNoz team! I'm trying to visualize exceptions/errors in SigNoz logged using ASP.NET Core 6 ILogger interface. E.g.:

logger.Error("Some error message");

I've added OTLP logging to the service:

services.AddLogging(logging =>
            {
                logging.ClearProviders();

                logging.AddConsole();

                logging.AddOpenTelemetry(options =>
                 {
                     options.SetResourceBuilder(resourceBuilder);

                     options.IncludeScopes = true;
                     options.ParseStateValues = true;
                     options.IncludeFormattedMessage = true;

                     if (UseConsoleExporter(monitoringSettings.LoggingExporter))
                         options.AddConsoleExporter();

                     if (UseOtlpExporter(monitoringSettings.LoggingExporter))
                     {
                         options.AddOtlpExporter(otlpOptions =>
                         {
                             otlpOptions.Endpoint = new Uri(monitoringSettings.OtlpEndpoint);
                         });
                     }
                 });
            });

But the exception page is always empty (see the screenshot). Do I need to add something to the otel-collector? I could not find and "extension" or additional "service. Traces and Metrics were send successfully.

Hello, I want to deploy a signoz cluster using the helm chart however the documentation is a bit inconsistent and I'm not sure what's true. In the documentation at https://signoz.io/docs/install/kubernetes/gcp/ it says to override the following values to set the storage class

clickhouse:
  cloud: gcp
  installCustomStorageClass: true
  persistence:
    storageClass: gce-resizable

But the documentation then links to the github (https://github.com/SigNoz/charts/tree/main/charts/signoz#configuration) but these values are not documented. There are some of them that are similar but on a different component

alertmanager.persistence.enabled	Enable volume persistence	true
alertmanager.persistence.storageClass	Set storage class for persistent volume	nil
alertmanager.persistence.accessModes	Set access mode for persistent volume	[ReadWriteOnce]
alertmanager.persistence.size	Set storage size	100Mi

Hello, My Application is not showing up in "Metrics" tab in frontend. I am new to Signoz I have locally setup my application and signoz. I can see my traces in the "traces" tab but metrics are not showing up. My application is a tomcat webapp. My env variables are

export CATALINA_OPTS="-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005 -javaagent:/Users/anand/libs/opentelemetry-javaagent.jar"

export OTEL_RESOURCE_ATTRIBUTES=service.name=MyApp

export OTEL_METRICS_EXPORTER=otlp

Hello, How to download the source code & docker image of the Signoz collector to the local system ?
