Checkmk Werk 11080: Port Checkmk to Python 3

by Lars Michelsen

ID: 11080 Title: Port Checkmk to Python 3 Component: Core & setup Level: 3 Class: New feature Version: 1.7.0i1 Most of Checkmk is written in Python. We have been developing on Python 2 for over 10 years now and are now taking the big step of porting Checkmk to Python 3 with Checkmk 1.7. This is a very big change in the software which has cost us a lot of time. But this step is necessary to continue to develop Checkmk efficiently and safely. In the past, Python 2.7 with all necessary 3rd party modules have been shipped in Checkmk for a long time. This Python 2.7 will no longer be shipped with Checkmk 1.7. Instead we now ship Python 3.8 with all necessary 3rd party modules. This is especially important if you use your own plugins or scripts. You have to consider the following things. If you have a script that is called directly from a cronjob or the core, e.g. a notification script, you have often used the shebang "#!/usr/bin/env python" in the past. By doing so, you have used the Python 2.7 that we shipped. Since this no longer exists, "python" of the operating system is used without further adaptation. This can be a Python 2.7, it depends on your system. We recommend changing the shebang to "#!/usr/bin/env python3". This will allow you to use the Python that comes with Checkmk again. After you have done this, you may need to adjust some things in your scripts to change your code from Python 2 to 3. We will publish more information about the conversion of plugins and scripts soon.

Checkmk Werk 11078: Dynamic configuration: Add connector plugin API

by Lars Michelsen

ID: 11078 Title: Dynamic configuration: Add connector plugin API Component: DCD Level: 2 Class: New feature Version: 1.7.0i1 The Dynamic configuration is now loading plugins that are located below the path <tt>local/lib/check_mk/cee/dcd/plugins/connectors/</tt>. You can find a minimal example connector implementation it in your site at <tt>lib/check_mk/cee/dcd/plugins/connectors/example_connector.py</tt>. You may use this as base for your own connectors. To enable this connector, you need to copy it to the plugin directory mentioned above and uncomment the registry registration lines in the plugin (See TODO). To be able to configure connections based on this connector in the GUI, you also need to deploy a GUI plugin. An example can be found in your site at <tt>lib/check_mk/gui/cee/plugins/wato/example_dcd_connector.py</tt>. This needs to be placed in the WATO plugin directory of your site. You also need to uncomment the registry registration line in the plugin (See TODO).

Checkmk Werk 11098: Proxmox: add VM backup status check

by Frans Fürst

ID: 11098 Title: Proxmox: add VM backup status check Component: Checks & agents Level: 2 Class: New feature Version: 1.7.0i1 This check makes sure every VM has a recent backup. The information is taken from log entries collected by the agent via API since Proxmox does not provide us with backup status (yet?). The check plugin optionally checks against existence and age of the last backup and shows some additional info like date, size and bandwidth.

Checkmk Werk 11122: Proxmox: add VM info check

by Frans Fürst

ID: 11122 Title: Proxmox: add VM info check Component: Checks & agents Level: 2 Class: New feature Version: 1.7.0i1 This check is OK when a given Proxmox VM's {status} matches a configured value, WARN otherwise. It shows {vmid} (e.g. "101"), {status} (e.g. "running"), {type} ("lxc" or "qemu") and {host} values returned by the API for the given VM.

Checkmk Werk 11072: Distributed environments: Improve config synchronization

by Lars Michelsen

ID: 11072 Title: Distributed environments: Improve config synchronization Component: WATO Level: 3 Class: New feature Version: 1.7.0i1 Synchronizing configurations between the central and remote sites has taken too much time in the past because the entire configuration was always synchronized. Even files that are still present on the remote site were completely synchronized, which led to increased computing effort, traffic and runtime. This mechanism has now been replaced by an incremental mechanism. Before each synchronization, the system determines which files already exist on the remote site. Only those files are synchronized that differ from the central site. For the migration from Checkmk 1.6 to 1.7 the change is compatible. Both central 1.6 sites can communicate with remote 1.7 sites and 1.7 central sites can communicate with 1.6 remote sites. Mixed environments should only be used for migration purposes. In such a scenario, the previous synchronization mechanism is used. After 1.7 this compatibility mode will be removed.

Checkmk Werk 10934: sap_hana_status is now multiinstance compatible

by Timotheus Bachinger

ID: 10934 Title: sap_hana_status is now multiinstance compatible Component: Checks & agents Level: 2 Class: New feature Version: 1.7.0i1 The agent plugin mk_sap_hana already delivers data per SID. Now also the check sap_hana_status will generate a service for the status and version per SID. If you already discovered such services, rediscovery is needed.
