Checkmk Werk 11108: Resolving of plugins default parameters during discovery

by Moritz Kiemer

ID: 11108 Title: Resolving of plugins default parameters during discovery Component: Checks & agents Level: 1 Class: New feature Version: 1.7.0i1 This werk only affects users that use an *.mk file in etc/check_mk/conf.d/ to override the default parameters of a check plugin. Previously the reference to this variable was saved in the autochecks, such that the value of corresponding variable was determined just before each execution of the check plugin. Now the value of the variable is evaluated during discovery, and the resulting value will be saved in the autochecks and used for every subsequent execution of the check plugin. Autochecks that have references to variable names in them will be converted during the update process to Checkmk 1.7 or by running `cmk-update-config -v` manually. Users that use an etc/check_mk/conf.d/*.mk file to set these default parameters are encouraged to configure an appropriate WATO rule instead.

Checkmk Werk 11205: cisco_prime_wifi_access_points: New check plugin which monitors Cisco Prime WiFi access points

by Frans Fürst

ID: 11205 Title: cisco_prime_wifi_access_points: New check plugin which monitors Cisco Prime WiFi access points Component: Checks & agents Level: 1 Class: New feature Version: 1.7.0i1 This check returns {{OK}} when the percentage of non-operational access points does not rise above configurable levels. Default values are {{(20%, 40%)}}. It shows the total number of access points as well as the number of access points marked {{Critical}}, {{Minor}} or {{Cleared}}. The needed {{cisco_prime_wifi_access_points}} sections are generated by {{agent_cisco_prime}} which has to be configured to fetch the required data through the Cisco Prime API by providing the respective URL and connection credentials.

This can be done either when configuring the default parameters for the discovered services of the <tt>ps<\tt>-check (rule "Process Discovery") or directly via the rule "State and count of processes".

Checkmk Werk 11247: Preserve piggyback data during restart and updates

by Lars Michelsen

ID: 11247 Title: Preserve piggyback data during restart and updates Component: Site Management Level: 1 Class: New feature Version: 1.7.0i1 For performance reasons, the Piggyback data is stored in the tmpfs of the site (in tmp/check_mk/piggyback). This has the disadvantage that the files disappear as soon as the checkmk server is restarted or the tmpfs is unmounted (e.g. during an update). The lack of piggyback data can temporarily lead to incorrect check results and, if you use the Dynamic Configuration, even cause certain hosts/services to disappear from the configuration for a short time. With this change the content of tmp/check_mk/piggyback and tmp/check_mk/piggyback_sources is saved to var/omd/tmpfs-dump.tar during certain actions (currently: omd stop, omd umount). If the "omd start" detects that tmpfs needs to be reinitialized, the backup from var/omd/tmpfs-dump.tar is restored to the fresh tmpfs.

by Jonas Kluger

ID: 11126 Title: ucd_cpu_util: Fix wrong CPU utilization Component: Checks & agents Level: 1 Class: Bug fix Version: 1.7.0i1 This fixes a wrong calculation in the check. The CPU utilization used the wrong values. The rates for each value got calculated twice which resultet in bogus results.

by Lars Michelsen

ID: 11085 Title: Icon upload: Add missing transaction validation Component: WATO Level: 1 Class: Security fix Version: 1.7.0i1 The transaction IDs (CSRF tokens) were not validated while processing the upload of icons. This alone is not a security hole, rather a lack of validation of this call.

Checkmk Werk 11221: systemtime: Offset for vSphere special agent

by Joerg Herbel

ID: 11221 Title: systemtime: Offset for vSphere special agent Component: Checks & agents Level: 1 Class: Bug fix Version: 1.7.0i1 The check <tt>systemtime<\tt> reported an incorrect offset when checking the output of the vSphere special agent. This was caused by the runtime of the special agent itself and has now been fixed. The check <tt>systemtime<\tt> can now process a second, optional input which gives the timestamp against which the actual offset is computed.

Checkmk Werk 11246: Drop classic theme

by Lars Michelsen

ID: 11246 Title: Drop classic theme Component: Multisite Level: 2 Class: New feature Version: 1.7.0i1 With this change we remove the Classic theme. Even though there are still many fans of this theme who like to use our Classic Theme, we can no longer support this theme in the future due to cost and effort. Users of the Classic Theme will automatically be switched to the current default theme. The main reason for this change is that we will make massive changes to the user interface of Checkmk with the upcoming version. We can easily implement these changes in the modern and dark theme together. In addition, we would have had to redesign and implement some of these in the Classic theme, which we cannot afford.
