Logging is done every time a user or the system wants to refresh a dataset.
The logging entries wiill be saved in its own repo called: no.ssb.eventlog. You can use the
datatoolbox to see the logging entries.
The event log functionality use the repo and node wrapper libraries
to connect to and manipulate nodes.
This is mainly done from the eventLog.ts library.
The query.ts library have functions specifically for manipulating query log entries.
The job.ts library have functions that manipulate job nodes.
The logging repo have two "top" nodes: /queries and /jobs.
Under the /queries, each dataquery in the content studio
will have a 1:1 relation with a node. This is done by using the dataquery id from the
content studio as a node name. That way, it is easy to get a query node by fetching the
data from /queries/[dataquery._id]
In a query node, there is information about the last
events for this dataquery its dataset. What happend and when it happend by who.
When a new event are being logged, a new log entry will be saved as a child node of the query node.
So a log for dataquery with id 1234, will be saved under /queries/1234/
Every day at 08:00 or 09:00, a cron job is set up to fetch new datasets. This is logged under /jobs.
Each job will have its own node with the information about which dataqueries that is being updated, when the job
started and ended, and the result of the data requests.
