Check_MK Werk 6106: Raw Edition: Fixed checking of some hosts when check speicific config variables are used

by Lars Michelsen

ID: 6106 Title: Raw Edition: Fixed checking of some hosts when check speicific config variables are used Component: Core & setup Level: 2 Class: Bug fix Version: 1.6.0i1 When check specific configuration variables are set in the Check_MK configuration, they could make the Check_MK checks of hosts that are not using these checks fail. This resulted in Check_MK services showing an empty output. When executing the precompiled host checks on the command line in debug mode, errors are shown. Like this: python /omd/sites/beta/var/check_mk/precompiled/[hostname] -v Cannot read in configuration file /omd/sites/[site]/etc/check_mk/conf.d/wato/rules.mk: name 'fileinfo_groups' is not defined

Check_MK Werk 6105: CMC check helper: Fixed issues related to check includes not being loaded

by Lars Michelsen

ID: 6105 Title: CMC check helper: Fixed issues related to check includes not being loaded Component: Core & setup Level: 2 Class: Bug fix Version: 1.6.0i1 When using the Check_MK Microcore several random checks could not be executed because the helper were not loading the check includes in all cases. This was some kind of race condition which could happen during check helper initialization. This regression was introduced with 1.5.0b3.

Check_MK Werk 6103: Check and discovery parameters were not always reloaded

by Lars Michelsen

ID: 6103 Title: Check and discovery parameters were not always reloaded Component: Core & setup Level: 2 Class: Bug fix Version: 1.6.0i1 Changed check specific check and discovery parameters were not always updated during config reload ("Activate changes"). This made the Check_MK and Check_MK Discovery services not recognize the changed parameters when reloading the config. The parameters were only loaded during next core restart. This regression affected all previous 1.5 beta releases.

Check_MK Werk 5812: Fixed Check_MK check helper crashes related to loading of precompiled checks

by Andreas Boesl

ID: 5812 Title: Fixed Check_MK check helper crashes related to loading of precompiled checks Component: Checks & agents Level: 2 Class: Bug fix Version: 1.6.0i1 The latest versions no longer read checks as plain text python files (Werk 6046). The operation which generates the precompilated file was not atomic, so a file could be partially written, while being read by another process. This caused various exceptions in multiple checks.

Check_MK Werk 6097: Raw Edition: Fix possible "(null)" output of Check_MK services

by Lars Michelsen

ID: 6097 Title: Raw Edition: Fix possible "(null)" output of Check_MK services Component: Core & setup Level: 2 Class: Bug fix Version: 1.6.0i1 The Check_MK service of multiple hosts may terminate without proper error message resulting just in status output "(null)" in specific situations. This happened when the precompiled host check files (var/check_mk/precompiled/[host]) were executed by Nagios using the system wide Python interpreter instead of the site specific interpreter.

Check_MK Werk 5277: cmk-update-agent: Add support for proxy servers

by Andreas Umbreit

ID: 5277 Title: cmk-update-agent: Add support for proxy servers Component: agents Level: 2 Class: New feature Version: 1.6.0i1 The agent updater is now able to connect to the Check_MK server via proxy. With this werk, a new checkbox "Use proxy server" is added to the Agent Updater rule configuration. You can now either configure a HTTP, SOCKS4 or SOCKS5 proxy (with optional credentials) or choose to follow the environment variables "HTTP_PROXY" and "HTTPS_PROXY" that may be set locally on the hosts. Please note that the configuration default is still set to ignore local proxy settings.

Check_MK Werk 6057: Changed GUI internal API functions

by Lars Michelsen

ID: 6057 Title: Changed GUI internal API functions Component: Multisite Level: 2 Class: New feature Version: 1.6.0i1 During development of version 1.6 we have made a lot of internal changes to the GUI internal code. In case you developed you own GUI extensions, you may likely be affected by this. The following table tries to summarize the most relevant changes to make it easier for you to port your custom code: <h3>Moved exceptions to <tt>gui_exceptions</tt> module</h3> Use <tt>from gui_exceptions import ..</tt> to import the exception objects you need. Available are: MKAuthException, MKUnauthenticatedException, MKGeneralException, MKUserError, MKInternalError. <h3>Moved lqencode() to livestatus module</h3> Use <tt>import livestatus</tt> and <tt>livestatus.lqencode()</tt>. <h3>Moved format_plugin_output() to views</h3> Use <tt>import view</tt> and <tt>views.format_plugin_output()</tt>. <h3>Moved make_nagios_directory() and make_nagios_directories() to cmk.store</h3> Use <tt>import cmk.store</tt> and <tt>cmk.store.mkdir()</tt> or <tt>cmk.store.makedirs()</tt>. <h3>Dropped create_user_file()</h3> Use <tt>cmk.store.save_file()</tt> instead. <h3>Dropped bytes_human_readable()</h3> Use <tt>cmk.render.bytes()</tt> instead. <h3>Dropped date_human_readable()</h3> Use <tt>cmk.render.date()</tt> instead. <h3>Dropped percent_human_redable()</h3> Use <tt>cmk.render.percent()</tt> instead. <h3>Moved make_utf8() to cmk.utils</h3> Use <tt>cmk.utils.make_utf8()</tt>. <h3>Moved quote_shell_string() to cmk.utils</h3> Use <tt>cmk.utils.quote_shell_string()</tt>. <h3>Moved pnp_cleanup() to cmk.utils</h3> Use <tt>cmk.utils.pnp_cleanup()</tt>. <h3>Moved aquire_lock(), release_all_locks(), have_lock() and release_lock() to cmk.store</h3> Use e.g. <tt>cmk.store.aquire_lock()</tt>. <h3>Dropped age_human_readable()</h3> Use <tt>cmk.render.approx_age()</tt> instead. <h3>Moved render_scientific() to cmk.render</h3> Use <tt>cmk.render.scientific()</tt>. <h3>Moved render_scientific() to cmk.render</h3> Use <tt>cmk.render.physical_precision()</tt>. <h3>Moved several functions to new utils module</h3> Use e.g. <tt>utils.drop_dotzero()</tt>. These have moved been moved: <ul> <li><tt>drop_dotzero()</tt></li> <li><tt>cmp_version()</tt></li> <li><tt>num_split()</tt></li> <li><tt>saveint()</tt></li> <li><tt>savefloat()</tt></li> <li><tt>get_random_string()</tt></li> <li><tt>gen_id()</tt></li> <li><tt>load_web_plugins()</tt></li> </ul> <h3>Dropped tryint()</h3> This has totally been dropped. Implement it on your own in case you really need this.

Check_MK Werk 5977: Fixed broken dropdown fields in several places

by Lars Michelsen

ID: 5977 Title: Fixed broken dropdown fields in several places Component: Multisite Level: 2 Class: Bug fix Version: 1.6.0i1 Some dropdown (select) fields were broken in Check_MK 1.5.0 for a longer time, especially in WATO configuration dialogs.
