stats(healthcheck-freq()) problems about syslog-ng

[alltilla]

As the release note states, it is a metric, not a log. syslog-ng-ctl stats prometheus prints it for you.

[czanik]

No, it's not included in syslog-ng-ctl stats prometheus but:

~# syslog-ng-ctl healthcheck
syslogng_io_worker_latency_seconds 6.1191000000000004e-05
syslogng_mainloop_io_worker_roundtrip_latency_seconds 0.00010469800000000001
syslogng_internal_events_queue_usage_ratio 0

However, my problem is not related to syslog-ng-ctl, but to the syslog-ng.conf option.

[alltilla]

It is included on stats(level(1));

I see no point of setting healthcheck-freq(). We behave the same way for level() or freq(), too: syslog-ng does not start with a syntax error.

[bazsi]

My understanding is that the example may have been not the best one in the NEWS entry, e.g. it should have included an example frequency value, whereas now it only has an empty set of brackets.

@czanik I'd close this unless you think we can do something to improve this.
