prometheus metrics

[fcomte]

We should expose prometheus metrics :

• counter for packages creation by package and user
• counter for packages deletion by packages and user
• running duration of the service when deleted

[alexisdondon]

do you suggest metrics like this?
onyxia_service_creation_total{service="jupyter-python",user="user or group",} 3.0
onyxia_service_deletion_total{service="jupyter-python",user="user or group",} 3.0

CAUTION: Remember that every unique combination of key-value label pairs represents a new time series, which can dramatically increase the amount of data stored. Do not use labels to store dimensions with high cardinality (many different label values), such as user IDs, email addresses, or other unbounded sets of values.

To do that you should look forward aggregations log system for high cardinality metrics -> ELK for example.
