Hello I follow this https://signoz.io/blog/opentelemetry-php/#instrument-your-php-app-with-opentelemetry tutorial and not see any data in http://localhost:3301/trace?

Any tips or guides on what the capacity requirements are per million traces/hour for SigNoz. I am starting to enable it in our PROD env and have moved a few services and am generating tens of millions of traces per hour at the moment. Want to understand how I should calculate how much capacity i need for clickhouse and the collectors. Thanks!

Hi team! I downloaded signoz and installed it on my machine but I can't create an admin account as an invite is required How to get this invite? It's very weird becouse how get invite using environment in localhost.

Hi team, I have deployed signoz in gcp cluster and configure with ingress and it is up and running. Configured my backend application with loadbalancer:4317 also done. In signoz UI I'm getting response code 500 and response as :

{
  "data": null,
  "total": 0,
  "limit": 0,
  "offset": 0,
  "errors": [
    {
      "code": 500,
      "msg": "Error in processing sql query: code: 516, message: admin: Authentication failed: password is incorrect or there is no user with such name"
    }
  ]
}

can any one help me on this please

I setup S3 config for clickhouse and a move factor of 0.1 so i thought it would automatically move to S3 when disk is almost full but that didn’t seem to work. I then tried changing retention via SigNoz UI and got this exception, any ideas what this means?:

[31mERROR[0m	clickhouseReader/reader.go:2275	error while setting storage policy. Err=code: 36, message: New storage policy `default` shall contain volumes of old one
<http://go.signoz.io/signoz/pkg/query-service/app/clickhouseReader.(*ClickHouseReader).setColdStorage|go.signoz.io/signoz/pkg/query-service/app/clickhouseReader.(*ClickHouseReader).setColdStorage>
	/go/src/github.com/signoz/signoz/pkg/query-service/app/clickhouseReader/reader.go:2275
<http://go.signoz.io/signoz/pkg/query-service/app/clickhouseReader.(*ClickHouseReader).SetTTL.func2|go.signoz.io/signoz/pkg/query-service/app/clickhouseReader.(*ClickHouseReader).SetTTL.func2>
	/go/src/github.com/signoz/signoz/pkg/query-service/app/clickhouseReader/reader.go:2119

Wondering if there is some kind of config where we can have clickhouse just delete data if disk is close to full instead of needing to oversize the disk to fit some number of days which can fluctuate based on service usage. This way you can then tell how many days you start to store (as it would be less and less days if load increases) and can increase size of disk after to accommodate (usually easier to increase a size of the disk than reduce).

Hi Team, we had to create dashboards to configure metrics. Is there a way to see all host metrics in a single pane.

Hi there 👋 I have a question related to the alerts behaviour. Even though I have configured alerts without any trouble, when the alert state should go back from Firing to Ok, it tends to suffer much delay in comparison with the actual application state. I have developed the following example in my localhost to manage a controlled environment: • I have coded a little kotlin application with two fake endpoints: one that always returns HTTP 200 and another always returns HTTP 500. • I configured an alert based on the PromQL query that SigNoz executes to retrieve the error percentage in the application dashboard. In my example, I was interested in measuring the error percentage in the last five minutes. • I started a load test for 25 minutes against the 200 ok HTTP endpoint. At the same time, I ran a load test for 40 seconds against the 500 error HTTP endpoint. • With that scenario, I achieve an error rate of around the 18%. • Under these conditions, I observed that the alert state went from Ok to firing as I expected. In the same way, I received a slack notification notifying me that the alert was triggered. • However, even though my application error percentage returned to 0 again and more than five minutes elapsed, the alert state kept on firing. The alert state returned to Ok after 30 minutes approximately. Could you help me to understand what is happening? I copy here the query that I’m running to trigger the alert:

max(sum(rate(signoz_calls_total{service_name="ktor-test", operation=~`HTTP GET|HTTP POST`, status_code="STATUS_CODE_ERROR"}[5m]) OR rate(signoz_calls_total{service_name="ktor-test", operation=~`HTTP GET|HTTP POST`, http_status_code=~"5.."}[5m]))*100/sum(rate(signoz_calls_total{service_name="ktor-test", operation=~`HTTP GET|HTTP POST`}[5m]))) < 1000 OR vector(0)

And my condition on the Alert are the following: • Send a notification when the metric is: above • the threshold: at least once • Alert Threshold: 5 Thanks in advance!

Hi Team, need some help on how to integrate the DB and external calls tracing.

Hi! I have some general questions. I just found out about SigNoz and i have worked with monitoring/observ for a while now. I'm looking for a more easy way of setting up surveillance for hybrid solutions. "opensource". I have worked with tools such as Zabbix/Datadog/op5"nagios"/prometheus"grafana stack",loki,tempo,mimir. Tools like newrelic/Datadog/logicmonitor is easier to start with, but cost a lot. And the most opensource-tools takes to much time to instrument and get to work as you want. and "sometimes hard to understand documentation". For example. To just to get monitor a jvm with jmx scraper in prometheus you need to do too many steps. Zabbix is opensource and they are trying to become more like DataDog with APM monitoring, logs, Distributed Tracing.. but they are not mature for APM yet. Do you guys think the same as me? For now i will try out SigNoz together with odigos.io see if it's easy to setup. So you will get logs,metrics,traces in same place without a headache. And does SigNoz use's a agent like other tooling? Is SigNoz mainly focusing on APM or is it also monitor server's etc? Thanks! 🙂

Hi Team, can someone guide me on how to send AWS Cloudwatch Metrics to SigNoz

Hello, I see that in the built in signoz logs there are trace_id and span_id fields but they are always empty. How can I enrich my log with the actual trace ids and connect log to trace and vice versa. Thanks!

Hi team! I'm having a problem sending log from my application to SigNoz, signoz received my logs but the information is not readable. Can someone help me ?

Hi, Is there a way to write alerts/notifications on 1. p99 latencies 2. rate of errors thrown 3. rate of logs being thrown based on specific keys, like container name, log level etc Apart from promql, Raw clickhouse queries from your own codebase will also work for me

Hey is it possible to send application logs to signoz using golang sdk ?

Hi. Does instrumenting services with OpenTelemetry affect the latency? I've observed an increase in latencies in a range of 5-15% in my services. Is there some way to optimize it? I'm using it in nodejs.

Hi, I'm following the instructions in this article and am experiencing this issue. Open-telemetry released their experimental SDK 0.34.0 (with metrics GA); with this version of node-sdk, the program described in the article will not work (it requires a metrics configuration). By using the 0.33.0 SDK, the program worked as well as in the article, but I wonder if there may be a better solution.

Hello, I am setting up signoz again after some time. We are installing on kubernetes with helm. I wanted to ask where all I will have to make changes If I want to restrict all signoz pods to run on a specific node group. I can see that there are toleration parameter for all the components but wanted to confirm which would be the correct place in helm to do that? Also please suggest if there's any other way of doing this. Thanks!
