Metrics: "Average number of logins per month to oSPARC averaged over the quarter reported on"

[elisabettai]

Creating this issue to collect all the information regarding this metric. I guess they want to know on average how many logins we have per month.

In Grafana (AWS prod) we have a graph that doesn't make a lot of sense.

At least, in march the graph was continuous (I got the one below from here)

The query used is: sum by (endpoint) (rate(http_requests_total{endpoint=~"/v0/me", http_status=~"2[0-9]+", app_name=~".+webserver"}[30d]))*60*60*24*30 The same query in Prometheus gives a different graph.

@sanderegg, @mrnicegyu11 does the graph in Prometheus make sense to you? I guess we'll need to fix it in Grafana.

Also, I was thinking that we can use the endpoint "/v0/auth/login" (which doesn't seem to be triggered twice as "/v0/me"). Anything speaks against this?

@elisabettai : concerning the graph in grafana, I am aware that the display in grafana has an issue because that metric is created at long intervals. something like every hour or so. and it seems grafana is not happy with it.

concerning the /v0/auth/login it depends what we want to show:

• this entrypoint is only triggered if you really go through the login page
• it is not triggered if your browser has the cookies set, and you open osparc everyday

@elisabettai : also the fact that the /me is triggered twice seems to be a bug. One option could be also that we define a specific metric with very well defined properties (then we could potentially test it to prevent it from going wrong).

[elisabettai]

A specific metric with well defined properties sounds like the cleaner solution. Where can we start from? Does this require change in simcore code?

I am also OK continuing using the existing one http_requests_total{endpoint=~"/v0/me", http_status=~"2[0-9]+", app_name=~".+webserver", unless in your experience that causes troubles (apart from the bug that it is triggered twice).

@elisabettai we can close this right?
