Searching with the "Host check command (regex)" or "Service check command
(regex)" filter did not behave like other regex filters in Checkmk: typing
http returned no results, because the regex was internally anchored to the
beginning of the stored value (which starts with the full command name, e.g.
check_mk_active-httpv2).
This anchoring originated from the previous dropdown-based filter, where the user picked a complete command name. After werk #19818 turned the filter into a free-form regex input, the anchoring became counter-intuitive.
The filter now performs a case-insensitive substring regex match, in line
with all other regex filters. Typing http matches every command that
contains http. Existing saved views and dashboards continue to work; they
may match a wider set of rows than before, but never fewer.
