Advanced WLM usage: Using performance metrics
Configuring WLM for metric-based SLOs
Appendix H 481
Is a floating-point value ranging from 0 to 0.999. The
default value is 0, resulting in no smoothing. Values
closer to 1 result in more smoothing.
NOTE Do not use cntl_smooth for metrics that are expected to equal zero in
SLO condition expressions. For example, do not use smoothing globally
if your configuration uses the sg_pkg_active collector to indicate a
Serviceguard package is active (1) or inactive (0). You could use
cntl_smooth in metric-specific tune structures in such a configuration,
as long as those structures are not for Boolean metrics.
Smoothing occurs only in WLM intervals in which a new metric value is
received.
The metric value reported in the log file /var/opt/wlm/wlmdstats is the
smoothed value.
