    @Ankit @Ankit Singhal @Prashant Shahi is it possible to sit sidecar in django deployment in order to export the metric to otel-collector in SigNoz if this can't be resolved https://signoz-community.slack.com/archives/C01HWQ1R0BC/p1650894714657889 or maybe using OpenTelemetry Operator instead ? https://github.com/open-telemetry/opentelemetry-operator#opentelemetry-auto-instrumentation-injection any suggestion?

    Does anybody have experience to using OpenTelemetry auto-instrumentation/agents to export data to SigNiz ? I setup OpenTelemetry operator and install autoinstrumentation in cluster, also I can see the auto-instrumentation is working but seems the mertric and trace didn't export to signoz-otel-collector. any documents or support can help ? here is testing application configuration, pls advice, thanks @Prashant Shahi @Ankit Nayan @Ankit

    @Prashant Shahi @Srikanth Chekuri @Ankit Nayan today I logged in sample-django-deployment-6fd7b76ccc-694gz pod to test my-release-signoz-otel-collector and my-release-signoz-otel-collector-metrics if working properly, and found the command mentioned in https://signoz.io/docs/instrumentation/python run successfully but seems no any data logged in otel-collector or otel-collector-metric , I can' t see any logs in otel-collector or otel-collector-metrics as well as the dashboard , but if I telnet those endpoint, it is working and shows the logs in both , can you help on that ? yesterday @Prashant Shahi helped to checked everything I deployed cannot find any issue but Signoz just can show any data in dashboard and didn't work properly.

    Hi team, I am Atul. I am new to SigNoz. I am trying to view HDD, Memory usage of all my VMs in one place. So far, I have setup a SigNoz dashboard on a VM (let's call it VM-0) using this (https://signoz.io/docs/install/docker/). Can some help me on how to send HDD and Memory usage stats from VM-1 to VM-0 so that it can be visualised on the dashboard?

    Hello team! Thank you for providing and supporting SigNoz! I am currently testing SigNoz application and found something that may be a bug in UI. Steps to reproduce: Select any trace to analyze Go to the bottom of the page Click on Rows per page setting button Try to change the value from 10 to any available The UI does not shows the selected rows quantity Please let me know if there's already a solution for this or if I'm doing something wrong. Many thanks!

    Hi #support, need help with filtering based on http headers, i am looking to filter the traces based on a http header e.g. nonce or any other header, how do i do this with Signoz, this is a Spring Boot service, i am making a REST API call with nonce as 123 in the header, unable to filter it here based on the header ?

    Hello Team! I was following this document which guide us to send node exporter data to SigNoz. I have noticed that on step Find Metrics available in Signoz at:
    2. Connect to clickhouse instance in SigNoz
    ./clickhouse client --host <SigNoz IP>  --port 9001
    We see that the document indicate us to connect on port 9001 of SigNoz IP but when I try to run it on lab environment I got this:
    [root@localhost /]# clickhouse client --host localhost --port 9001
    ClickHouse client version 22.4.4.7 (official build).
    Connecting to 127.0.0.1:9001 as user default.
    Code: 210. DB::NetException: Connection refused (172.18.0.3:9001). (NETWORK_ERROR)
    As per my Docker environment I have this IP address to my ClickHouse server:
    [root@localhost /]# docker ps
    CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
    c683e0184777 yandex/clickhouse-server:21.12.3.32 "/entrypoint.sh" 13 hours ago Up 43 minutes (healthy) 8123/tcp, 9000/tcp, 9009/tcp clickhouse-setup-clickhouse-1
    [root@localhost /]# docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' c683e0184777
    172.18.0.3
    Checking the ClickHouse server config file I see below reference for ports:
    <http_port>8123</http_port>
    <tcp_port>9000</tcp_port>
    <interserver_http_port>9009</interserver_http_port>
    Which seems to match the ports seen on docker ps above. When I run the connection command with container IP and port 9000 the connection is successfull:
    [root@localhost /]# clickhouse client --host 172.18.0.3 --port 9000
    ClickHouse client version 22.4.4.7 (official build).
    Connecting to 172.18.0.3:9000 as user default.
    Connected to ClickHouse server version 21.12.3 revision 54452.
    This is a documentation inconsistency or a particularity on my lab environment? If so, should I update the documentation to guide user to follow my steps? Many thanks!
