Hi Claude,
Wouldn't it be easier to actually have a module for exposing metrics, like
jena-prometheus? Or jena-metrics? JupyterHub does that
(https://github.com/jupyterhub/jupyterhub/blob/master/jupyterhub/metrics.py),
but it's as easy to implement that in Java as in Python.
That way you could display the metrics on Graphana
(https://prometheus.io/docs/visualization/grafana/), or Kibana
(https://www.elastic.co/guide/en/beats/metricbeat/master/metricbeat-module-prometheus.html),
or even plug into another monitoring system like Nagios
(https://github.com/prometheus/nagios_plugins), Zabbix
(https://www.zabbix.com/integrations/prometheus), etc.
Having some Zeppelin module/kernel (use Python notebooks, but guess there's
something with the same name) would be interesting. Write SPARQL queries, show
how the installation of Jena Text can be done, with assembler files with syntax
highlighting. There are a few possible use cases, though I suspect it should be
possible to do these items with Python Notebooks/Zeppelin now (plus some glue
code).
CheersBruno

My understanding of Graphana is that they provide charts (aka visual graphs
but just to keep the nomenclature clear I will call them charts) for data.
They are source agnostic and currently talk to a number of databases. The
idea is to allow a user/admin to create queries that would be charted by
Graphana. Very early investigation. I was just wondering if such a module
would be a good fit for the "extras".
I also think that having adapters to make it easy to pull and display data
from Jena/Fuseki might bring an up-tick in adoption. At one time I thought
about Zeppelin as a frontend.
