Checkmk Werk 12835: Service label conditions could lead to wrong rule matches

by Lars Michelsen

ID: 12835 Title: Service label conditions could lead to wrong rule matches Component: Core & setup Level: 2 Class: Bug fix Version: 2.1.0i1 The matching of service rule sets (which are used for a lot of different settings in Checkmk) could lead to wrong rule matching results in case service labels were used. This issue was only triggered in a specific condition: Multiple services on different hosts on the same site with the same service description had to use the exact same set of label keys (the text before the ":") with different label values (the text after the ":"). In this case it could happen that the rule value of one service affected the rule value of another service. For example, this could lead to services being added to a service group which should not be added to that group.

Checkmk Werk 12831: Improve page breaks when rendering graph columns over multiple pages

by Lars Michelsen

ID: 12831 Title: Improve page breaks when rendering graph columns over multiple pages Component: Reporting & Availability Level: 2 Class: Bug fix Version: 2.1.0i1 This change fixes a layout problem of reports or PDF exports of views containing graph columns which fill multiple pages. Previous Checkmk versions were displaying one or multiple empty pages in such a situation or pages which are not fully populated by graphs. The layout of graphs columns has now been improved to work better in common situation. Even though the new layout algorithm is better than the previous one in specific situations, there are still several cases that are not handled ideally. To improve this further would require major rebuilding work that cannot be done as part of a bug fix of the stable version.

Checkmk Werk 12322: Standalone Windows exe files are no more included in distro to avoid false positives from antiviruses

by Sergey Kipnis

ID: 12322 Title: Standalone Windows exe files are no more included in distro to avoid false positives from antiviruses Component: Linux Distributions Level: 2 Class: Bug fix Version: 2.1.0i1 In the past we delivered in the shipped package few Windows exe files, which were either intended to be installed on their own or should serve as an example. However some antivirus programs produced false positives for these files. Because in this version the agent installation can only be carried out using the MSI and the example is no more relevant, all exe files have been removed from the shipped package thus fixing the problem with antivirus software.

Checkmk Werk 12828: Distributed setup: Fix parallel activations breaking remote sites

by Lars Michelsen

ID: 12828 Title: Distributed setup: Fix parallel activations breaking remote sites Component: Setup Level: 2 Class: Bug fix Version: 2.1.0i1 Previous 2.0.0 versions could break the Checkmk configuration on remote sites when two users tried to activate changes for a single remote site at the same time. This was a race condition between both processes. While the first activation performed the synchronization to the remote site, the second activation could modify the files that are currently being synchronized by the first process. This could lead to incomplete configurations on the remote site. Since the first activation did not know anything about this inconsistency, it tried to activate the incomplete configuration on the remote site after the sychronization which could fail with different error messages depending on which files were not transfered. This issue only affected the configuration of remote sites. No configuration was lost on the central site. If you want to prevent this issue with previous 2.0.0 releases, you need to ensure that you don't start two activations for a site at the same time.
