    Maybe I posted in wrong channel, so will try here 🙂 Does anyone know how to get Signoz up and running on EKS with fargate? Stuck on taint/toleration issue: 0/7 nodes are available: 7 node(s) had taint {eks.amazonaws.com/compute-type: fargate}, that the pod didn't tolerate. I tried to understand the helm charts in the github repo, but I just don't know enough about helm to figure this out. It seems like there's a way to provide tolerations as part of the helm chart deployment, but again, don't know enough (had to read up on Kubernetes just to to figure out what taints/tolerations are, and only now have a basic understanding of how they work. It is basic. At best. And that's being generous to myself :') I tried with some various random attempts to put it inside variables, but no luck. (Using CDK against EKS Fargate). Any help would be appreciated.
    const tolerations = [
          {
            key: "<http://eks.amazonaws.com/compute-type|eks.amazonaws.com/compute-type>",
            operator: "Equal",
            value: "fargate:NoSchedule",
            effect: "NoSchedule"
          },
          {
            key: "<http://eks.amazonaws.com/compute-type|eks.amazonaws.com/compute-type>",
            operator: "Equal",
            value: "fargate",
            effect: "Schedule"
          }
        ];
    
        this.cluster.addHelmChart('signoz', {
          namespace: 'signoz', 
          createNamespace: true,
          repository: '<https://charts.signoz.io>',
          chart: 'signoz',
          release: 'signoz-r1',
          values: {
            zookeeper: { // test if zookeeper pods will schedule, did not work
              tolerations
            },
            tolerations, // Putting it right at the root? Nope, didn't work.
            global: {
              storageClass: "ebs-sc",  
              tolerations        // Maybe global will work? Nope.
            },
            clickhouse: {
              cloud: "aws",
              installCustomStorageClass: false
            }
          },
          wait: false
        });

    Hi everyone, I'm trying to implement signoz example distributed tracing java application. everything is OK. however, when I want to visualize traces in signoz dashboard the tutorial uses nodejs to generate some data to trace. I'm very concerned about that. So, is there any way to use postman that makes some call microservice for example? I use Docker as in the example. Can anyone help me with this?

    Before we can start wrapping OpenTelemetry into their applications, is there some guides on getting telemetry from the basic components like Apache and MySQL?

    and then, once we start getting telemetry info from them, maybe then we start looking at integrating the OpenTelemetry SDK's into their applications

    If I have multiple server environments that are independent from each other, each running their own app, mysql server etc... do I need multiple SigNoz installations to see them separately?

    Hi, I'm looking for replacement for our current monitoring/obervability stack. Currently we are grabbing metrics and logs using metricbeat and filebeat (and some other beats) and sending them to ELK stack. Can we achieve something similar with SigNoz? Currently I see it supports only pull base data (like Prometheus) but I would like to push all data into some public endpoint from monitoring system (like Logstash do). The best will be if we can stay with metricbeat and filebeat and just change the endpoint. In general I would like to build one monitoring system i central location and send there data from all other environments.

    Hi, is there an option to aggregate SigNoz data from multiple SigNoz instances into a single one? I have multiple k8s clusters, I want to have a SigNoz deployment on each of them (to monitor a single cluster they been deployed at), and in addition I want to have a centralized SigNoz instance that will aggregate all the ‘single’-SigNoz data. I also want to be able to navigate between the different SigNoz instances-data. Today Im implementing this setup using prometheus & thanos & grafana. Thanks 🙂

    Hi Team , I have created a Python application that runs on my one EC2 server. Then I created a new EC2 instance to install SIgnoz. I am integrating my application with Signoz. It will not show up on dash boards. Also, I have checked out troubleshooting point 2. You have mentioned the connectivity of opentelementary. Could you please help me out ?

    Are you trying out the sample app or are you instrumenting your own application? Can you share more details about the application / framework / library details and how you are running it? Can you try using the
    console
    exporter and confirm it emits the telemetry to stdout?

    hello. I have installed Signoz from Helm on microk8s, but the frontend is failing to initialize:
    Conditions:
      Type              Status
      Initialized       False 
      Ready             False

    Volumes:
      nginx-config:
        Type:      ConfigMap (a volume populated by a ConfigMap)
        Name:      signoz-frontend
        Optional:  false
      kube-api-access-z6hqd:
        Type:                    Projected (a volume that contains injected data from multiple sources)

        DownwardAPI:             true
    It is looking for a ConfigMap called nginx-config, but there isn't one. Where does that come from?

    hi all, just found out about this tool from hacker news super excited to start integrating it into our dev and prod environments!! we just moved away from datadog as it was too cost prohibitive for us. Any tips on scaling this out properly with services getting millions of requests an hour would be greatly appreciated!

    hello, my Signoz pods started getting evicted overnight due to low ephemeral storage. There's plenty of disk on the node, so I'm not sure what it's complaining about. I even put limits on the ephemeral storage that a pod could use, but something is still running the pods out of this storage type. How do I configure more or figure out what's eating it all up?

Hi @Vishal Goel ! We have tested SigNoz chart with Nginx ingress controller and Cert Manager. It worked fine for us.
Let me test with alb and get back to you.
Have you tried referring to official alb guide? https://docs.aws.amazon.com/eks/latest/userguide/alb-ingress.html
