system_events_show_zero_values
Allows to select zero-valued events fromsystem.events.
Some monitoring systems require passing all the metrics values to them for each checkpoint, even if the metric value is zero.
Possible values:
- 0 — Disabled.
- 1 — Enabled.
system_metric_log_show_zero_values_in_histograms
Controls whether zero-valued histogram data is written to thehistograms nested column of system.metric_log.
By default, histograms whose total observation count is zero are skipped, and within each emitted histogram, bucket entries with no observations are also omitted from the histogram map. Enable this to write every histogram and every bucket regardless of count — useful for monitoring systems that require every metric to appear at every checkpoint.
Possible values:
- 0 — Disabled. Histograms with
count = 0are not emitted; emitted histograms include only buckets that received at least one observation. - 1 — Enabled. All histograms are written, and every bucket boundary appears in
histogram.
