[Exist-open] Performance monitoring for exist

[Willem v. d. W. <wi...@kw...>]

Hi everyone,

We want to implement some performance observability tools for exist. Two 
questions:

1. Is it possible to access the $jmx object from outside existdb as in 
the snippet below. Any pointers for us to look

<instance name="localhost"
     url="http://localhost:8080/exist"
     token="3268b570-392e-56ea-9550-117012413e15" cron="0 * * * * ?">
     <poll cron="0/30 * * * * ?" store="yes">
     <alert name="More than 30 threads waiting for locks to be released"
         condition="count($jmx//LockManager/WaitingThreads/row) > 30"/>
     <alert name="More than 40 brokers active"
         condition="$jmx//Database/ActiveBrokers &gt; 10"/>
     <alert name="Process CPU load &gt; 1.0"
         condition="$jmx//UnixOperatingSystem/ProcessCpuLoad &gt; 0.5"/>
     </poll>
</instance>

2. Has anybody looked at reading and writing that object to prometheus?
