Checkmk Werk 13093: Limit various fields lengths when writing to the monitoring history.

by Sven Panne

ID: 13093 Title: Limit various fields lengths when writing to the monitoring history. Component: cmc Level: 1 Class: Bug fix Version: 2.2.0i1 To protect against very long fields coming e.g. from notification plugins and other external sources, the CMC will put limit to various fields which are written to the monitoring history. If such a field is too long, it's simply truncated. This is a simple protection against huge memory consumption of the CMC, which caches log lines for faster views and SLA computations. Limits (non-configurable for now): <ul> <li>Comment: 2000 bytes</li> <li>Plugin output: 1000 bytes</li> <li>Long plugin output: 2000 bytes</li> </ul> Note: For fields coming from the Python side (i.e. notifications), it's actually characters, not bytes.

Checkmk Werk 13691: Renew old site certificates during update

by Moritz Kiemer

ID: 13691 Title: Renew old site certificates during update Component: Setup Level: 1 Class: New feature Version: 2.1.0i1 Older certificates that do not include the server name extension need to be updated in order to support the new agents TLS encryption. The old certificate is moved to <tt>[my_site].pem.bak</tt>, and a new one is created. The existing site local root CA, which signed the previous certificate, is used to sign the new certficate. Since the trust between distributed sites is established with the local root CA, no additional action is needed.

Checkmk Werk 13623: New default dashboards for linux and windows

by Marcel Arentz

ID: 13623 Title: New default dashboards for linux and windows Component: Multisite Level: 2 Class: New feature Version: 2.1.0i1 With this werk 4 new default dashboards are added to Checkmk. These are: * Linux hosts: A default dashboard to be used for a (smaller) group of Linux hosts, e.g. a cluster. You will find this dashboard in the "Overview" topic of the Monitor menu. * Windows hosts: A default dashboard like the above but for windows hosts. * Single Linux host: A host specific dashboard for Linux hosts. This dashboard is available through the context of a Linux host or though the link of the particular host in the overview dashboard. * Single Windows host: A host specific dashboard like the above but for windows hosts. You will find the group dashboards on Monitor > Overview and below the entry "All hosts". Both dashboards are prefilterted to hosts with the according operating system. But the scope is a smaller group of related host, e.g. a cluster of linux or windows server. Because of that it is recommended, to add more filters to get an actual overview of a specifc group of linux/windows hosts. The single host dashboards linked in the host name column, reachable through the "Host information" dashlet of the group dashboard. Alternatively you can reach them through the host overview itself by the "Host" dropdown at the topic "Overview".
