by Lars Michelsen

ID: 5732 Title: BI aggregations are now customer aware Component: WATO Level: 2 Class: New feature Version: 1.5.0i3 The configuration if the BI aggregations is now handled in a customer aware way by the Check_MK Managed Services Edition.

Check_MK Werk 5671: Use RE2 regular expression engine for Livestatus queries.

by Sven Panne

ID: 5671 Title: Use RE2 regular expression engine for Livestatus queries. Component: Livestatus Level: 2 Class: New feature Version: 1.5.0i3 Livestatus offers various places where a regular expression can be used, e.g. in its "Filter:" header for GET queries. The previous implementation had various problems, which have all been fixed by switching to a new regular expression engine (RE2, see https://github.com/google/re2): <ul> <li>Unicode was not handled correctly: RE2 fully understands UTF-8, so this has been fixed.</li> <li>Unbounded memory usage during matching: This could lead to stack overflows and CMC/Nagios crashes when trying to match some classes of regular expressions on long inputs. RE2 guarantees that this won't happen, it either complains that a regular expression is too complicated (which is hard to provoke) or runs in constant memory afterwards.</li> <li>Exponential runtime: Some classes of regular expressions could lead to exponential runtime, blocking Livestatus threads and using CPU time for some millenia or more. RE2's runtime is linear in the size of the regular expression and the input, so this has been fixed, too.</li> </ul> As an additional bonus, most of the time RE2 is quite a bit faster than the previous implementation. RE2's regular expression syntax (https://github.com/google/re2/wiki/Syntax) is basically a superset of the previous POSIX extended regular expression syntax (http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap09.html#tag…), so you won't have to change your patterns. Note that one esoteric detail is different, though, namely the semantics of submatching (see https://swtch.com/~rsc/regexp/regexp2.html#posix). If you relied on this, you probably already had some problems, because almost every POSIX regex implementation out there was buggy in some way (see https://wiki.haskell.org/Regex_Posix#Results_and_Bugs).

Check_MK Werk 5670: Handle history files from older EC versions, which have fewer columns.

by Sven Panne

ID: 5670 Title: Handle history files from older EC versions, which have fewer columns. Component: Event Console Level: 1 Class: Bug fix Version: 1.5.0i3 History files written by older versions of the EC might contain fewer columns than a newer EC handles. This fix fills these missing columns with their default values, avoiding log messages like unknown precedence '' in table eventconsolehistory in cmc.log later.

by Lars Michelsen

ID: 5730 Title: Graph export can now use custom consolidation function Component: metrics Level: 1 Class: New feature Version: 1.5.0i3 In addition to werk #8643 it is now possible to provide the optional key <tt>consolidation_function</tt> to control which consolidation function should be used when calculating aggregated numbers. Possible values are: <ul> <li><tt>"consolidation_function": "max"</tt> - The default</li> <li><tt>"consolidation_function": "min"</tt></li> <li><tt>"consolidation_function": "average"</tt></li> </ul>

Check_MK Werk 5271: Better handling of erroneous deployment information in Agent Bakery

by Andreas Umbreit

ID: 5271 Title: Better handling of erroneous deployment information in Agent Bakery Component: agents Level: 1 Class: Bug fix Version: 1.5.0i3 Depending of the state of the agent deployment information file for a host, the pages "Automatic agent updates" and "Agent update status" would crash and show only partial information. This is now mitigated by handling corrupt agent deployment files per-host and displaying an error message in a convenient format and location on the affected pages.
