Checkmk Werk 11851: Windows agent MSI checks that Windows OS is appropriate for installation

by Sergey Kipnis

ID: 11851 Title: Windows agent MSI checks that Windows OS is appropriate for installation Component: Setup Level: 2 Class: New feature Version: 2.1.0i1 Previously, it was possible to configure the Windows agent in WATO in such a way that installing on older operating systems would cause the Windows agent updater to fail( or make such plugins as mk_jolokia or mk_logwatch more inoperable). For example: setting of the <tt>Standard python environment(3.8+ )</tt> and deploy such MSI on Windows 2008. This could cause complete falling out of the host of the monitoring, because the installed standard Python, 3.8+, can't work on Windows 2008. With this release the problem has been solved. If during deployment configuration is not supported by Windows OS, the installation will not be performed: the MSI will always check Windows version and stops own installation if, Windows OS doesn't match to MSI requirements. The host will continue to operates normally in any case. Nevertheless, you need to fix the configuration in WATO in the order to make the update for older Windows system. In the case of the aforementioned example, you have to select <tt>Deploy legacy environment (Python 3.4 + standard set of modules)</tt> in the rule <tt>Install Python runtime environment</tt>, activate changes and bake the agent.

Checkmk Werk 12050: Consolidation of interface check plugins

by Moritz Kiemer

ID: 12050 Title: Consolidation of interface check plugins Component: Checks & agents Level: 1 Class: New feature Version: 2.1.0i1 A lot of interface checks did exactly the same thing. The new check API allows us to consolidate them into one check plugin {{interfaces}}, without affecting the user. The following check plugins will be replaced by the new one: {{statgrab_net}}, {{emc_vplex_if}}, {{vms_if}}, {{if_brocade}}, {{if_lancom}}, {{ucs_bladecenter_if}}, {{aix_if}}, {{if}}, {{if_fortigate}}, {{hp_msa_if}}, {{if64_tplink}}. The transition to the new services is done during `cmk-update-config`. Existing rules will apply as before, no metrics will be lost. It may slightly change the "Service check command" count of the {{site_objects_counts}} plugin, depending on its configuration.

Checkmk Werk 11979: apache_status: HTTPS support for Python 2.6, 3.0, 3.1, 3.2, 3.3, 3.4

by Ulrich Bschorer

ID: 11979 Title: apache_status: HTTPS support for Python 2.6, 3.0, 3.1, 3.2, 3.3, 3.4 Component: Checks & agents Level: 1 Class: New feature Version: 2.1.0i1 In some python versions (2.6, 3.0, 3.1, 3.2, 3.3, 3.4) the agent plugin 'apache_status' crashed with the error message: "Exception (...: urlopen() got an unexpected keyword argument 'context'". This happens only if an HTTPS connection is established. The reason for this is that in previous Python versions "urllib.urlopen" did not support the 'context' parameter. This werk introduces an alternative handling of "urllib.urlopen" for affected python versions. If you want to use this feature you have to redeploy this agent plugin.

Checkmk Werk 12143: Graph dashlets: Optionally disable time range synchronization

by Lars Michelsen

ID: 12143 Title: Graph dashlets: Optionally disable time range synchronization Component: Multisite Level: 1 Class: New feature Version: 2.1.0i1 When a dashboard has multiple graph dashlets showing different time ranges, it may be not intended to synchronize the time ranges by zooming into a single graph. By default Checkmk synchronizes the time ranges and pins of all graphs on a page. This can now be disabled for each graph dashlet individually by setting the graph rendering option "Do not follow timerange changes of other graphs on the current page".

Checkmk Werk 10614: Improved hexagon visualization on dashboards

by Kenneth Okoh

ID: 10614 Title: Improved hexagon visualization on dashboards Component: Multisite Level: 1 Class: Bug fix Version: 2.1.0i1 Host/Service statistics dashlet: LI: Up hosts and OK services are now displayed in green again, not in grey as was recently implemented. Site/Host overview dashlet: LI: The dashlet is now responsive to dashboard filters. LI: Host and service state colors are now in line with Checkmk standards. Before, down hosts were shown in yellow (now red) and unknown services as well as unreachable hosts in red (now orange). LI: The positioning of hexagons in the dashlet was fixed so they do not overflow beyond the dashlet borders anymore.

Checkmk Werk 12235: Permissions issues for DB2 Linux agent plugin

by Joerg Herbel

ID: 12235 Title: Permissions issues for DB2 Linux agent plugin Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 The Linux agent plugin for monitoring DB2 instances (<tt>mk_db2</tt>) had a permissions issue when being deployed via the agent bakery. The plugin tried to call itself as a DB2 instance user, however, the directory where the plugin is located requires root permissions. For this fix to come into effect, users have to re-bake and update the Linux agent for all affected systems.
