Check_MK Werk 6315: mssql_backup: Fixed missing default levels

by Simon Betz

ID: 6315 Title: mssql_backup: Fixed missing default levels Component: Checks & agents Level: 2 Class: Bug fix Version: 1.6.0i1 Werk 6143 removed the empty default levels. The consequence was that all passive checks were gone because the default levels variable name was unknown to Check_MK und therefore the autochecks could not be read. This was introduced in Check_MK version in 1.5.0b8.

Check_MK Werk 6358: Fixed stale services on cluster nodes

by Lars Michelsen

ID: 6358 Title: Fixed stale services on cluster nodes Component: Core & setup Level: 2 Class: Bug fix Version: 1.6.0i1 When using Check_MK clusters it could happen that some of the services on a node went stale and remained in this state. In this situation you can find multiple messages in the cmc.log when using the CEE: 2018-07-21 12:47:52 [5] [Check_MK helper 4644] started, commandline: /omd/sites/beta/bin/cmk --keepalive 2018-07-21 12:48:42 [2] [Check_MK helper 4644] ignoring check result for lxclu1 / Filesystem /boot: no such service 2018-07-21 12:48:43 [4] [Check_MK helper 4644] restarting dead helper 2018-07-21 12:48:43 [5] [Check_MK helper 4644] exited normally The issue was triggered because the cluster nodes reported service check results for services which are assigned to the cluster using the "Clustered services" rule set. The problem could only happen when services of one check type were assigned to the cluster and the cluster node. For example in case you have at least one Filesystem service assigned to the node and at least one Filesystem service assigned to the cluster. This regression was introduced with 1.5.0b7 (Werk #5814).

Check_MK Werk 6345: Fixed invisible/lost notification rules when editing notification rules

by Lars Michelsen

ID: 6345 Title: Fixed invisible/lost notification rules when editing notification rules Component: Notifications Level: 2 Class: Bug fix Version: 1.6.0i1 Since werk #4167 it was possible to prevent users from configuring specific notification plugins by setting the notification plugin permissions to "no". As a result all notification rules that use the not permitted notification plugin were not visible anymore to this user. This hiding of rules could be confusing and lead to bugs. We decided to show all rules now but prevent modifications of these rules when the user is not permitted to perform the modifications. When cloning notification rules or creating notification rules with identical parameters only one of the rules was shown. The others could be hidden, but still be in existing. In other situations, when a user with limited permissions on notification plugins edits the notification rules, it could happen that all notification rules that use other plugins were deleted by accident. These problems were introduced with werk #4167. CMK-556

Check_MK Werk 5505: Multiple formats for Agent Updater executable on Linux

by Andreas Umbreit

ID: 5505 Title: Multiple formats for Agent Updater executable on Linux Component: agents Level: 2 Class: New feature Version: 1.6.0i1 Since Check_MK 1.5.0i2, the Linux Agent Updater executable (cmk-update-agent) got deployed as a 64bit binary executable file, see Werk #5267 for details. After regarding some customer feedback, we decided to bring back the cmk-update-agent python script to Check_MK and additionally offer a 32bit binary executable format. As a result, you can now choose between 3 executable formats for the cmk-update-agent executable to be deployed by configuring the entry "Executable format (Linux/UNIX)" within the Agent Updater ruleset: "64bit ELF executable", "32bit ELF executable" and "Python2 script", with 64bit executable being the default if no rule entry is configured. Additionally, the rule entry will be ignored on Windows hosts, so there is no need to manually exclude your Windows hosts from a ruleset. Please note that the deployment of the Python2 script may bring back some old problems (for details, see again Werk #5267) and hence we can offer no support for troubleshooting while deploying the Agent Updater as a script. However, a mail to feedback(a)check-mk.org is much appreciated.

Check_MK Werk 6226: Allow to match against the monitoring site in rules

by Konstantin Büttner

ID: 6226 Title: Allow to match against the monitoring site in rules Component: Event Console Level: 2 Class: New feature Version: 1.6.0i1 This allows to apply rules only on specific sites. Restricting rules to sites can yield performance benefits in environments with many sites. Beyond that, this is required to make the feature expect regular messages work in a distributed environment with config replication. Example: If you have three centrally configured event consoles, and you want a device to regularily report to one of them, you previously had no way to configure that only the one site reports missing messages. Instead, all sites the device doesn't send messages to would repeatedly open events. This limitation can now be worked around by specifying to which site expect rules should apply.

Check_MK Werk 6342: Fixed degraded SNMP check performance when using SNMP sub checks

by Lars Michelsen

ID: 6342 Title: Fixed degraded SNMP check performance when using SNMP sub checks Component: Checks & agents Level: 2 Class: Bug fix Version: 1.6.0i1 When checking a host with SNMP sub checks which normally all get the same data, the data was fetched multiple times. One time for each subcheck used for monitoring a host. This resulted in significantly increased check times and time outs. All 1.5 versions are affected by this issue. We experienced this issue with a CMCiii device which is normally monitored by a set of sub checks (cmciii.*).

Check_MK Werk 6096: Check_MK GUI is now shipped via mod_wsgi as WSGI application

by Lars Michelsen

ID: 6096 Title: Check_MK GUI is now shipped via mod_wsgi as WSGI application Component: Multisite Level: 2 Class: New feature Version: 1.6.0i1 This change should be seamless for most users, but may be interesting especially for users that use custom GUI extensions. In case you only use the GUI as it is and are not interested in technical details, you can skip the following details. With this change we replaced mod_python apache module with mod_wsgi. Mod_python has been "deprecated" for several years. These days all modern python based web applications are built using the WSGI standard. There are a lot of implementations of WSGI applications out there. To have a smooth transition we decided to use the mod_wsgi apache module as application server for the GUI. It is now shipped with Check_MK instead of mod_python. We have made the necessary changes to the GUI to work as WSGI application. Some other cleanups and modifications have been made on the way. <ul> <li>Move index file to dedicated app folder as recommended for WSGI apps</li> <li>Move several things from htmllib.html to dedicated helper classes <ul> <li>http.Request -> HTTP request parsing (from WSGI env)</li> <li>http.Response -> HTTP response processing (for WSGI)</li> <li>htmllib.TimeoutManager -> Handle GUI task timeouts</li> <li>htmllib.TransactionManager -> Mange GUI action transaction IDs</li> </ul> </li> <li>Cleaned up several other things in the htmllib and parent classes</li> </ul> The following changes have been made to the htmllib.html API: html.set_cookie() -> html.response.set_cookie() html.del_cookie() -> html.response.del_cookie() html.get_request_header() -> html.request.get_request_header() html.lowlevel_write() -> html._lowlevel_write() html.remote_ip() -> html.request.remote_ip html.is_ssl_request() -> html.request.is_ssl_request html.request_method() -> html.request.request_method html.get_user_agent() -> html.request.user_agent html.get_referer() -> html.request.referer html.requested_url() -> html.request.requested_url html.request_uri() -> html.request.requested_url html.http_redirect() -> html.response.http_redirect() html.client_request_timeout() -> html.request.request_timeout html.get_cookie_names() -> html.request.get_cookie_names() html.has_cookie() -> html.request.has_cookie() html.cookie() -> html.request.cookie() html.uploaded_file() -> html.request.uploaded_file() html.request_timeout() -> html.request.request_timeout html.get_request_timeout() -> html.request.request_timeout html.set_ignore_transids() -> html.transaction_ids.ignore() html.get_transid() -> html.transaction_ids.get() html.store_new_transids() -> html.transaction_ids.store_new() html.urlencode_plus() -> html.urlencode() Dropped things: html.add_keybinding() html.add_keybidings() html.disable_keybindings() html.keybindings_enabled html.keybindings html.RETURN html.SHIFT html.CTRL html.ALT html.BACKSPACE html.F1 html.u8() html.utf8_to_entities() html.varencode()
