Hello, I want to monitor Apache. For this, in otel-collector-config.yaml I have added these lines: receivers: Apache: endpoint: "http://localhost:80/server-status?auto" Where can I see the metrics of my Apache server? In alerts I can't see the metrics.
s
Did you configure the server to enable status report?
j
Yes, I put in the browser http://localhost:80/server-status?auto and I see the status page.
Copy code
but I don't know where I can see the apache metrics.
s
If the collector can scrape successfully the metrics show up when you type the metric name dashboards or alerts. You may want to look at the logs if there are any issues while getting metrics from apache.
j
so in apache I don't have to do anything right? Where can the logs be seen?

You need to configure the 
httpd.conf
to let the collector receive the metrics
Where can the logs be seen?
In the pod/container for the collector where you configured the apache receiver. Remember just adding the receiver also doesn’t create metrics. You need to add it to the pipeline.

el apache esta bien configurado.

and on the other hand in otel-collector-config.yaml

I have configured this:

receivers:
  Apache:
    endpoint: "<http://localhost:80/server-status?auto>"
Copy code
but what has been said... from the Dashboard or Alert I see the metrics
Copy code
he apache log without problem. I see the calls to the status:

Copy code
on line 70 you will see:

  Apache:
    endpoint: "<http://localhost:8080/server-status?auto>"

You only added the receiver to the list but didn’t add it to the pipeline. As I mentioned earlier, just adding receiver alone doesn’t enable it you need to add it to the metrics pipeline.
j
Copy code
Would it also be added in?:

otel-collector-metrics-config.yaml

and how would it be done? I don't see anything in the documentation
s
Add the apache in the pipeline here
Copy code
metrics:
      receivers: [otlp]
      processors: [batch]
      exporters: [clickhousemetricswrite]
Copy code
metrics:
      receivers: [otlp, apache]
      processors: [batch]
      exporters: [clickhousemetricswrite]

Copy code
Thank you very much for the help.

I see the apache metrics
