WindowsHostRebooted compares against the last boot time of the previous
hour instead of the sample of ten minutes ago, so a scrape gap during
the reboot no longer suppresses the alert. WindowsServiceNotRunning
joins with ignoring() so instances with the same name in different
clusters do not match each other. Replacing the removed
networkErrorRateThreshold or networkDiscardRateThreshold knobs now
fails with a message naming the ratio thresholds.
The network error and discard runbooks describe the packet ratio, the
service runbooks explain PID reuse, shared host processes and selector
exclusions, and the tests cover alert recovery, a reboot after a scrape
gap and a service name repeated across clusters.
