Checkmk Werk 13857: Windows agent uses perflib to obtain wmi_cpuload data

by Sergey Kipnis

ID: 13857 Title: Windows agent uses perflib to obtain wmi_cpuload data Component: Checks & agents Level: 2 Class: New feature Version: 2.2.0i1 Windows agent uses now the Perflib API for service wmi_cpuload as a more reliable and stable source of information compared to the previously used WMI API. If, for some reasons, the new functionality causes problems, it is possible to return to the WMI API, using the appropriate key in the user config. To do it, set in section global the key cpuload_method to 'use_wmi'.

Checkmk Werk 14101: Add InfluxDB exporter

by Ronny Bruska

ID: 14101 Title: Add InfluxDB exporter Component: Setup Level: 2 Class: New feature Version: 2.2.0i1 With Checkmk 2.1 we introduce the new option to configure InfluxDB connections. With this option you are able to send metrics directly from Checkmk to the REST-API of InfluxDB. More information on how to configure the connection can be found here: https://docs.checkmk.com/master/en/metrics_exporter.html Please note: The integration is only compatible with InfluxDB 2.0 or later. If you're using InfluxDB <= 1.8 you need to use the option "Send metrics to Graphite" as described in the Checkmk docs.

Checkmk Werk 13297: Setup (WATO) now uses Redis for certain lookups to improve GUI performance

by Andreas Boesl

ID: 13297 Title: Setup (WATO) now uses Redis for certain lookups to improve GUI performance Component: Setup Level: 2 Class: New feature Version: 2.2.0i1 Large installations with several thousand hosts/folders suffered from a decreased performance when navigating through the folder hierarchy or when displaying rulesets. Furthermore, the global settings option <tt>Hide folders without read permissions</tt> made the entire setup system virtually unusable for non-admin users. Some of the data is now cached via Redis, which reduces needless calculations and file parsing.

Checkmk Werk 13897: Fix command injection vulnerability

by Maximilian Wirtz

ID: 13897 Title: Fix command injection vulnerability Component: Notifications Level: 2 Class: Security fix Version: 2.2.0i1 Previously to this Werk an attacker who could control certain notification variables such as <tt>NOTIFICATIONTYPE</tt> or <tt>HOSTNAME</tt> was able to inject commands to the fall-back mail command. The commands were then executed as site user. With this werk the variable <tt>MAIL_COMMAND</tt> is no longer available in notification scripts. You can reduce the risk of exploitation with disabling the listening of the notification spooler (the default is disabled) (CEE/CME only feature). All maintained versions (>=1.6) are subject to this vulnerability. It is likely that also previous versions were vulnerable. To detect possible exploitation <tt>var/log/mknotifyd.log</tt> and <tt>var/log/notify.log</tt> can be checked for special shell characters like <tt>&&</tt> and odd quoting.

Checkmk Werk 13644: Deprecating NSCA as part of Checkmk

by Lars Michelsen

ID: 13644 Title: Deprecating NSCA as part of Checkmk Component: Other Components Level: 2 Class: New feature Version: 2.2.0i1 With Checkmk 2.1 we officially deprecate the component NSCA which has traditionally been a part of Checkmk but was rarely used. In 2.1 it will work as before and be removed with Checkmk 2.2. If you are a user of NSCA with Checkmk an alternative solution depends on your specific use case. You could try to use local plugins with the Checkmk agent (https://docs.checkmk.com/latest/en/agent_linux.html#mrpe) or utilize the spool directory mechanism of the agent #16 (https://checkmk.com/werk/16). If you can't find a good replacement for your use case, please contact us via your support contact.

Checkmk Werk 13872: Add RobotMK GUI integration

by Ronny Bruska

ID: 13872 Title: Add RobotMK GUI integration Component: Multisite Level: 2 Class: New feature Version: 2.2.0i1 If you use the RobotMK extension package (mkp), each RobotMK service will now have an icon for the last log file and the last error log file in the action menu of the service, depending on the service labels "robotmk/html_last_log:yes" and "robotmk/html_last_error_log:yes". These icons lead to a new page on which the respective file is displayed and downloadable. Please note: You have to use at least version 1.2.9 of the extension package.

Checkmk Werk 13852: Win-agent installer creates allow-pull-mode file correctly

by Sergey Kipnis

ID: 13852 Title: Win-agent installer creates allow-pull-mode file correctly Component: Checks & agents Level: 2 Class: Bug fix Version: 2.2.0i1 Previously, custom action in MSI failed if the available Powershell was too old. Such failure made impossible the obtaining of the previously installed version of win-agent. For the use case <tt>update from 2.0 on 2.1</tt>, this means lack of connection between agent and site, i.e. stop of the monitoring. Since this release, the uninstaller custom action supports also Powershell 4.0 thus solving the problem.
