In the Clickhouse database, there are both tables and distributed tables. are they identical in terms of usage, just that you can configure it to use the distributed Clickhouse engine or are there some logic in signoz which decides when to use what?

Maybe more Clickhouse related than SigNoz, but why does it say unknown for the datatype here?

Hey Team, we have certain traces where there is a big gap between different services which breaks the ui. Any way to handle this cleanly?

Hello All we have a custom need to use our react themes rather than the out of the box Signoz UI . I know it is achievable but is there a signoz design in the UI such as spans etc . Please kindly clarify.

Hi everone - On the signoz trace section, how do you select multiple tag values from the list of possible values in the drop down? e.g. [Tag] [In] [Values] I'm trying to build a query: Tag in ("0","1","2","etc") but I can't figure out how to select multiple values? Once I select the first value from the drop down, I'm unable to select and add additional values.

Hello everyone - How I can monitor my API in SigNoz

Hi, I'm experimenting with Signoz on my local mac laptop and running into an issue getting the clickhouse-setup-otel-collector-1 container to start:

error while creating mount source path '/host_mnt/private/var/lib/docker/containers': mkdir /host_mnt/private/var/lib/docker: operation not permitted

I've tried deleting all images, restarting docker, etc. to no avail. Is there something obvious I'm missing?

Hi guys! I'm working in POC that integrate my services (using FastAPI) with Signoz. For that, I use the guide available on Signoz documentation: https://signoz.io/blog/opentelemetry-fastapi/

on a fresh install, shoudn't there me services/traces etc from the signoz services?

i see absolutely nothing in the frontend

the only thing that's working is logs

Hello! We are using otel collectors to gather logs, traces and metrics from our applications running in k8s. Exceptions view in Signoz if good, but there’s a small problem. We have same applications running in multiple namespaces (all are autoinstrumented) and it’s impossible to see from which namespace the exception is originated. You have to jump to trace graph in order to view k8s.namespace.name of the exception. Is there something planned which could help on this kind of use case? Another issue is the exception alarm. Alarm message about exception sent using slack webhook does not contain the information about namespace. This is something we would also like to have.

if anyone is interested, i have figured out how to connect istio with traces and metrics so it doesn't require another otel sidecar

the downside is that you lose log correlation but it's still very powerful

HI

Getting below error while installing signoz helm through flux signoz-apm-monitoring False Helm install failed: template: signoz/charts/k8s-infra/templates/otel-deployment/deployment.yaml5816: executing "signoz/charts/k8s-infra/templates/otel-deployment/deployment.yaml" at <include "snippet.otlp-env" .>: error calling include: template: signoz/charts/k8s-infra/templates/_helpers.tpl37812: executing "snippet.otlp-env" at <include "otel.endpoint" .>: error calling include: template: signoz/charts/k8s-infra/templates/_helpers.tpl25022: executing "otel.endpoint" at <.Chart.IsRoot>: can't evaluate field IsRoot in type interface {} False

Hello all

I haved setup the signoz with opentelemetry on kubernetes cluster, Installed the Opentelemetry collector, opentelemetry collector, and signoz. But not getting the traces on the signoid dashboard. Can anybody help me in this?

I am not getting any data from the opentelemetry is there anything more I need to configure except the default values.

Hi Team, is SigNoz beta version with Logs option in menu bar is free at the moment? didn't find that feature in free option at pricing page.thanks!

if free, how I can install it on EKS, any documentation specifically on beta version with logging option enabled. thanks again!

hi, i just joined. is there any documentation on contributing?

Hi, I'm just joined and currently trying to add FastAPI monitoring, but I'm stuck on one problem: I've done everything based on this guide, but while I'm checking collected info in SigNoz Traces/Dashboard I found out that there is no information about Http requests (URL, Method, etc) Maybe someone had similar issues, and can suggest any ideas?

Hello for exporting the traces of nodeJS application on EKS cluster to the signoz, or opentelemetry do we need to add anything to the code?

Hi there. I’m wondering about security in sending traces from the frontend to the backend. Couldn’t anyone send traces to the backend to try and make a DDOS attack. Is the collector built with this in mind? Is there an approach to ensure only authorized applications can send trace, log and metrics to the collector?

Hello there 👋 Just wanted to say thank you for creating open source tools for observability. I'm currently trying SigNoz, self-hosted and it looks wonderful so far.

👋 Hello, team! If i have two installations of signoz on two differents cluster, but with the same clickhouse database. When i installed second instance it forced me to re-init admin user at first login, i would like to have login screen, how can i do it ? Thanks for your help

Hello! I want to store the last month of Reddit's posts and comments and be able to search them fast. Is SigNoz a good tool for that?

I have tried Open Search, but what a mess that is

Hello, I'm trying to lower the log output from ClickHouse, through the Helm chart you provide. I tried to use the help in the

values.yaml

to do so, but it seems not to be working. Here my `values.yaml`: (I know I duplicated

default/log_queries=0

but it's on purpose to try to make it work).

clickhouse:
      defaultProfiles:
        default/allow_experimental_window_functions: "1"
        default/allow_nondeterministic_mutations: "1"
        default/log_queries: "0"
        logger:
          level: warning
      enable: true
      profiles:
        default/log_queries: "0"
        logger:
          level: warning
##this block doesn't work, clickhouse get error about unknown settings:
##      logger/level: "warning"
##end of test
      resources:
        limits:
          cpu: 2000m
          memory: 4Gi
        requests:
          cpu: 50m
          memory: 4Gi

But then, the pod gets deployed, and still shows information logs such as:

clickhouse 2023.03.06 16:32:04.571158 [ 234 ] {4483843e-d883-4d01-af4d-2872f07b4545} <Information> executeQuery: Read 170 rows, 674.05 KiB in 0.015092185 sec., 11264 rows/sec., 43.62 MiB/sec.

and on the pod, I can check some config files:

bash-5.1$ cat etc/clickhouse-server/config.d/01-clickhouse-02-logger.xml 
<yandex>
    <logger>
        <!-- Possible levels: <https://github.com/pocoproject/poco/blob/develop/Foundation/include/Poco/Logger.h#L105> -->

        <!-- Default behavior is autodetection (log to console if not daemon mode and is tty) -->
        <console>true</console>
    </logger>
</yandex>

Could you tell me what I'm missing here please? Thanks a lot
