get more metrics from syslog-ng

[saibug]

Hi,

Is there any way to collect more metrics about status of syslog-ng ?
for example memory_usage, queued messages for dst ....

I set stats-level to 3, but doesn't help .
This if the output of my syslong-ng-ctl query get "*" :

Metrics collected from exporter

Any idea ?

Thank you in advance
