Check_MK Werk 6984: docker_node_disk_usage, docker_node_info, docker_node_images, docker_node_network: Extract sections to plugin

by Konstantin Büttner

ID: 6984 Title: docker_node_disk_usage, docker_node_info, docker_node_images, docker_node_network: Extract sections to plugin Component: Checks & agents Level: 2 Class: Bug fix Version: 1.6.0i1 Due to poor performance of commands such as <tt>docker system df</tt> in some environments, the check_mk_agent would be slowed down to the point of unusability. To address this, these sections have been extracted into the <tt>mk_docker_node</tt> agent plugin, allowing them to be run asynchronously. If you update the agent and you need these sections, you will have to deploy the plugin to continue monitoring docker node information.

Check_MK Werk 6930: Service discovery page can now handle long running tasks

by Lars Michelsen

ID: 6930 Title: Service discovery page can now handle long running tasks Component: WATO Level: 2 Class: New feature Version: 1.6.0i1 The service discovery page of the configuration GUI could end up in timeouts when working with devices that need a long time to process the discovery process. This mostly affected either large or slow responding SNMP devices. The discovery page is now initially loading almost immediately and then starts fetching the content in the background. The potential long running tasks (full scan or autmatic refresh) are performed in the background. While these actions are performed, the GUI shows the already known check table in a read only mode. Discovering services of hosts monitored by remote sites using a pre 1.6 version is possible but can still end up in timeouts. The new logic is only used by sites using version 1.6 or newer.

Check_MK Werk 6920: HTTP proxies can now be configured globally

by Lars Michelsen

ID: 6920 Title: HTTP proxies can now be configured globally Component: Core & setup Level: 2 Class: New feature Version: 1.6.0i1 To enable components to connect to external resources in proxied networks more easily it is now possible to configure several HTTP proxies using the global setting "HTTP proxies". Imagine a scenario where your monitoring server is located in your company internal network and you need to make a connection to a external HTTP server in the internet while you can only connect to this server using a proxy server. In the past the most spread option is to set the HTTP(S)_PROXY environment variables for such a call and hope that the program you use for the connection supports these envrionment variables. Now it is possible to configure the proxies using the GUI in a central place and refer to these settings from different parts of your configuration. These proxies will be usable by e.g. special agents, notification scripts and active checks, which need to use a proxy for their work. As example the pushover notification script has been migrated to support the global proxy settings. Note to notification script developers: You have to name the notification proxy element of the Dictionary parameters valuespec "proxy_url" to make it work as expected with globally configured proxies. Note to special agent and active check developers: There is a new function available get_http_proxy(http_proxy). Pass the "http_proxy" value a user configured using the HTTPProxyReference valuespec to this function an you will get back the proxy URL as string or None in case no proxy should be set via command line (see "pydoc cmk_base.check_api.get_http_proxy_for_cmdline" for further information).

Check_MK Werk 6964: Fixed matching of literal strings when C++11 regex engine is used.

by Sven Panne

ID: 6964 Title: Fixed matching of literal strings when C++11 regex engine is used. Component: Livestatus Level: 2 Class: Bug fix Version: 1.6.0i1 Livestatus and CMC can use one of two regex engines: Either then one from the C++11 standard library or the one from the RE2 library. Normal builds ship the latter, only a manually built Livestatus should ever use the former. Nevertheless, both should work, but the C++11 variant had a quoting bug, resulting in incorrect matching. This has been fixed.

by Sven Panne

ID: 6963 Title: Removed /bauen directory from .deb packages Component: DEB Packaging Level: 2 Class: Bug fix Version: 1.6.0i1 Caused by a recent change, the .deb packages inadvertendly contained some build artifacts, resulting in some files being installed below /bauen. The 1.5.0 releases p8 and p9 were affected, but not p7 and earlier. This has been fixed.
