Hi,
we're running Fuseki 5.1.0 and are using the logging of Jena. That works
fine for us.
There is no logging of SPARQL Update statements though because those can
get to large in terms of text.
By the way, I would not run an ancient Fuseki 3.4.0 in production
anymore - is there a reason for this? just because it works?
Cheers,
Lorenz

Hi, all,
We’ve got a heavily-used webapp backed by Fuseki, and we’re having
issues with the load on the Fuseki server. It frequently heads into a
storm of high load average, with the CPU usage pegged at 600% (on 6
cores), and then the app grinds to a halt and we have to restart the
database. We’re trying to understand why this is happening. Is there
the ability in Fuseki to get a list of the currently-running queries
at any given point in time, including the query text itself, and
preferably also the amount of time each one has been running for?
We’re running Fuseki from Jena 3.4.0, if that makes a difference to
the answer.
Thanks,
Hugo.
