Check_MK Werk 7326: "Update DNS cache" action is now really cleaning up the cache

by Lars Michelsen

ID: 7326 Title: "Update DNS cache" action is now really cleaning up the cache Component: WATO Level: 2 Class: Bug fix Version: 1.6.0i1 As written in the documentation (https://mathias-kettner.com/cms_wato_hosts.html) Check_MK is keeping an internal DNS cache for the hosts that have configured no static IP address in Check_MK: --- With the host name method Check_MK uses cached data in order to minimise repeated DNS requests during an Activate Changes – which is very important for accelerating the activation procedure. Furthermore, the cache ensures that a changed configuration can still be activated if the DNS stops working. The catch is that Check_MK doesn't automatically notice the change to an address in DNS. For this reason, in the host details there is the button which deletes the entire DNS cache and forces a new resolution at the next Activate changes. This file is found under ~/var/check_mk/ipaddresses.cache in your instance, by the way. Deleting this file has the same effect as the button as described above. --- The problem was that previous versions did not really delete the entire cache, but only updated it. We have now changed this to make the cache invalidation work as intended.

Check_MK Werk 7247: ps.perf: Fixed incomplete counter cleanup routine, leading to ever-growing counter state files

by Andreas Boesl

ID: 7247 Title: ps.perf: Fixed incomplete counter cleanup routine, leading to ever-growing counter state files Component: Checks & agents Level: 1 Class: Bug fix Version: 1.6.0i1 The ps check regularly creates counter values with dyamic names and save them into the counter state file. There is a cleanup routine which removes outdated counters. This cleanup routine failed at cleaning up counter values from the deprecated ps.perf check. As a result the check counters file did steadily grow. This has been fixed. The cleanup now also checks for outdated ps.perf counters.

Check_MK Werk 7246: Prevent automatic discovery of duplicate services with the same service description

by Andreas Boesl

ID: 7246 Title: Prevent automatic discovery of duplicate services with the same service description Component: Checks & agents Level: 1 Class: Bug fix Version: 1.6.0i1 Hosts using snmp as well as tcp checks may run into a scenario where discovered snmp checks share the same service description as the tcp based checks. One example is the service description <tt>Uptime</tt>, which is created by the <tt>snmp_uptime</tt> and <tt>uptime</tt> check. In case of identical service descriptions, the tcp based check wins and the snmp based check is ignored.

by Konstantin Büttner

ID: 6988 Title: netstat: Fix crashing check on AIX 7 Component: Checks & agents Level: 1 Class: Bug fix Version: 1.6.0i1 The netstat command separates the port from the IP address with a dot (.) instead of a colon (:) on some AIX versions, which the check previously could not parse correctly. This has been fixed.

Check_MK Werk 7325: check_bi_aggr: Improve GUI application error handling

by Lars Michelsen

ID: 7325 Title: check_bi_aggr: Improve GUI application error handling Component: Checks & agents Level: 1 Class: Bug fix Version: 1.6.0i1 When the webservice detects an error -- such as an authentication problem -- it does not output the expected data structure, but a string starting with "ERROR:". This is now correctly being detected and the error is output as check output, rather than a nasty parsing exception.

Check_MK Werk 7242: Unreachable site errors respect site filters

by Lars Michelsen

ID: 7242 Title: Unreachable site errors respect site filters Component: Reporting & Availability Level: 1 Class: Bug fix Version: 1.6.0i1 When reports are being created while some distributed site is offline, the report is prefixed by a "error report" page that is added to inform the user that the report was created in such a situation and some data may be missing for this reason. The error message looks like this: "Not all sites have been queried. Some information is missing." The errors were shown for all sites, even when a specific site was queried. This was a problem, especially in Check_MK Managed Services Edition environments when creating customer specific reports in the management sites.
