Check_MK Werk 0970: liveproxyd: handle situations with more then 1024 open files

by Mathias Kettner

ID: 0970 Title: liveproxyd: handle situations with more then 1024 open files Component: Livestatus-Proxy Level: 2 Class: Bug Fix Version: 1.2.5i3 When you are using the Livestatus Proxy Daemon for connecting lots of sites and you have lots of concurrent users then two things could happen: 1. You might run out of files. The reason is that per default on most Linux systems the number of files a process is allowed to keep open is limited to 1024. The can be increased by using <tt>/etc/security/limits.conf</tt>. The script launching the <tt>liveproxyd</tt> need to issue a <tt>ulimit -S -n unlimited</tt> before starting. In the OMD builds of the Check_MK Monitoring System this has been added for recent development builds. The <tt>liveproxyd</tt> now handles this situation better and does not long run into a busy CPU loop. It waits for 5 seconds and restarts itself instead. 2. Even if you increased the number of allowed open files the <tt>liveproxyd</tt> could never open more than 1024 files on most Python versions (due to a limit of the system call <tt>select()</tt>. This has been fixed by using the <tt>poll()</tt> system call.

Check_MK Werk 0968: Notification plugins now configurable via WATO

by Mathias Kettner

ID: 0968 Title: Notification plugins now configurable via WATO Component: Notifications Level: 2 Class: New Feature Version: 1.2.5i3 Check_MK now has a new alternative API for notification script, which allows them to be configured via WATO. The classical API provided the possibility of a list of strings that was passed to the script as <tt>PARAMETER_1</tt>, <tt>PARAMETER_2</tt>, etc. The new API passes arguments according to keys in a configured dictionary, like <tt>PARAMETER_FROM</tt> and <tt>PARAMETER_REPLY_TO</tt>. Two notification scripts have been converted to use the new API: <tt>mail</tt> (sending HTML emails) and <tt>mkeventd</tt> (forwarding to the Event Console). The configuration of a notification script does only work with the new Rule Based Notifications can be done at two places: <ul> <li>In new rulesets below Host & Service Parameters → Monitoring Configuration → Notifications</li> <li>Right in a notification rule</li> </ul> Both configurations are being merged on a per-key basis. That way you can e.g. setup a <tt>From:</tt> header for your outgoing emails via a global rule, but select various different <tt>Reply-To:</tt> addresses in different notification rules. If a configuration key appears both in Host & Service Parameters and in a notification rule then the latter one has precedence.

Check_MK Werk 0965: Cumulative permissions and contact groups for WATO folders

by Mathias Kettner

ID: 0965 Title: Cumulative permissions and contact groups for WATO folders Component: WATO Level: 2 Class: New Feature Version: 1.2.5i3 WATO folders have now two new checkboxes in the Permissions attributes: <ul> <li>Give these groups also permission on all subfolders</li> <li>Add these groups as contacts in all subfolders</li> </ul> The first one will add the configured groups of a folder also as permitted groups to all subfolders (recursively). The second one will add the configured groups as contact groups to the hosts in all subfolders. The idea behind that is a simplification of the configuration. It is now sufficient to specify the groups of you more general administrators at the top of the folder tree and add more and more specific groups at the lower levels of your folder tree. In the table of hosts you now will see the permitted groups and the contact groups of a host as two separate columns.

Check_MK Werk 0964: Fix hanging shutdown of CMC on RedHat 5.X

by Mathias Kettner

ID: 0964 Title: Fix hanging shutdown of CMC on RedHat 5.X Component: Notifications Level: 2 Class: Bug Fix Version: 1.2.5i3 When using the CMC on RedHat/CentOS 5.X then the CMC would not correctly shutdown. The reason is, that the Python implementation of that OSes raises an Exception on sys.exit, while newer versions don't. This has been fixed by handling <tt>SystemExit</tt> explicitely.

Check_MK Werk 0963: New snapin with virtual host trees

by Mathias Kettner

ID: 0963 Title: New snapin with virtual host trees Component: Multisite Level: 2 Class: New Feature Version: 1.2.5i3 We have added a new snapin to Multisite: Virtual Host Tree. This snapin allows you to have trees of your hosts created based upon tags. In order to use this simply add the snapin to your sidebar and go to the Global Settings, section Status GUI (Multisite) and the new setting Virtual Host Trees. You can create an arbitrary number of virtual trees. They will be globally visible for all users. Each tree consists of a sequence of tag groups. Let's assume that you have created a virtual tree from the three fictive tag groups Location, Application and Criticality. The virtual host tree will then have tree levels. At the top level there is the selection of the location, on the second level the application and on the leaf-level the criticality. A click of an arbitrary node of the tree brings you to all hosts having the selected tags.
