Add support or metrics for daily request count monitoring

[benidk]

Hi team,

I’m currently looking for a way to monitor the daily number of requests in the system.
While exploring the available metrics, I found this one :

com_codahale_metrics_MetricRegistry_content_request_count

To estimate the daily volume, I created the following PromQL query :

increase(com_codahale_metrics_MetricRegistry_content_request_count[24h])

However, I noticed a significant difference between the value reported by this query in my monitoring dashboard and the request counter shown in the UI.

Before digging deeper, I wanted to ask :

Is this the right metric to track the number of requests?

If not, is there another metric that should be used for this purpose?

Or is there any known offset/difference between the UI counter and the exposed Prometheus metrics?

Thanks a lot!

~ For reference: I tried:

sum(
    increase(org_eclipse_jetty_ee8_nested_ContextHandler_CoreContextHandler_1xx_responses_total{instance="myNexus"}[24h])
    +
    increase(org_eclipse_jetty_ee8_nested_ContextHandler_CoreContextHandler_2xx_responses_total{instance="myNexus"}[24h])
    +
    increase(org_eclipse_jetty_ee8_nested_ContextHandler_CoreContextHandler_3xx_responses_total{instance="myNexus"}[24h])
    +
    increase(org_eclipse_jetty_ee8_nested_ContextHandler_CoreContextHandler_4xx_responses_total{instance="myNexus"}[24h])
    +
    increase(org_eclipse_jetty_ee8_nested_ContextHandler_CoreContextHandler_5xx_responses_total{instance="myNexus"}[24h])
)

But that value is also completely off.
Some docs how to get that value reported in the admin or additional metric would be nice.
Cheers.

There are a couple of ways to pull the request metrics:

Pull service metrics data: http://localhost:8081/service/rest/metrics/data and look for nexus.analytics.content_request_count gauge.

Also can call metrics APIs: /v1/monthly-metrics to get the last 12 months of metrics.
