Check_MK Werk 7227: Fixed liveproxy activating errors confusing site related web API calls

by Lars Michelsen

ID: 7227 Title: Fixed liveproxy activating errors confusing site related web API calls Component: WATO Level: 1 Class: Bug fix Version: 1.6.0i1 Unclean error handling could make site management related web API calls like set_all_sites fail because an ASCII error message was sent back as result to the API call instead of the expected JSON data structure.

Check_MK Werk 7205: jolokia_jvm_threading: new check for JVM threads

by Moritz Kiemer

ID: 7205 Title: jolokia_jvm_threading: new check for JVM threads Component: Checks & agents Level: 1 Class: New feature Version: 1.6.0i1 The new check jolokia_jvm_threading is introduced. It creates the services "JVM <instance> Threading" and optionally "JVM <instance> ThreadPool <pool name>", replacing the former checks jolokia_metrics.threads and jolokia_metrics.tp. The new "JVM Threading" check now allows to set rules on the thread count as well as on the rate at which new threads are created. Additionally levels for the daemon threads can be configured. Unlike for the old check 'jolokia_metrics.threads', no default levels are imposed on the thread count. Users who had a rule in place for the ThreadCount metric of the old check need to set up a new rule "JVM threading". The "JVM ThreadPool" check applies the same rule as the previous check did. A rediscovery is required for affected hosts.

Check_MK Werk 6762: zfsget: Fixed different behaviour of the plugin in Solaris and Linux

by Marcel Arentz

ID: 6762 Title: zfsget: Fixed different behaviour of the plugin in Solaris and Linux Component: Checks & agents Level: 1 Class: Bug fix Version: 1.6.0i1 Previously the implementation of getting zfs information was slightly different in Linux and Solaris. Now both agents are fetching data only for volumes and filesystems and are using the quota for computing the total size of a filesystem or volume. So the information of each service will be more precise.

Check_MK Werk 7226: LXC: Add basic support for Linux containers

by Lars Michelsen

ID: 7226 Title: LXC: Add basic support for Linux containers Component: Checks & agents Level: 2 Class: New feature Version: 1.6.0i1 The agent is now detecting when it is executed in a Linux container context and changes it's behaviour depending the environment. In containers the agent currently does the following: <ul> <li>lxc_container_cpu: This check is used instead of the normal CPU utilization check</li> <li>zfs filesystems are not excluded for the df section anymore</li> <li>kernel section is not processed, because it's the host systems kernel the agent reports information for</li> <li>drbd section is not processed for the same reason</li> <li>lnx_thermal section is not processed for the same reason</li> </ul>

Check_MK Werk 7062: Improvement of the graphing with PNP4Nagios for various checks

by Tom Baerwinkel

ID: 7062 Title: Improvement of the graphing with PNP4Nagios for various checks Component: Checks & agents Level: 1 Class: New feature Version: 1.6.0i1 When PNP4Nagios is used Check_MK tries to use autogenerated graph templates to paint the graphs of a check. If the capabilities for Check_MKs autogeneration of graph templates is insufficient Check_MK provides a fallback to handcrafted templates. This werk extends the capabilities of Check_MKs autogeneration of PNP templates and makes a lot of handcrafted PNP templates unnecessary. Therefore, these templates are removed. This results in an overall more pleasant and uniform graphing. PNP4Nagios is used if the raw edition is used or if the enterprise edition is used together with the Nagios core.

Check_MK Werk 7105: Check API: Make usage of dsname, unit, human_readable_func and infoname in check_levels clearer

by Simon Betz

ID: 7105 Title: Check API: Make usage of dsname, unit, human_readable_func and infoname in check_levels clearer Component: Checks & agents Level: 1 Class: Bug fix Version: 1.6.0i1 Previously the dsname was also used as title if and only if the infoname was not stated. Therewith we got cryptic and not readable titles. The dsname should only be used for performance data variables. Sometimes a title is not needed because the service description already gives the relevant information; especially in check plugins where there is just one {{thing}} to check, eg. in CPU services: Previously: CPU utilization OK - CPU utilization: 23.5% Now: CPU utilization OK - 23.5% In general the structure is as following: <ul> <li>If the infoname is specified the service detail is prefixed with this infoname as a title "TITLE: "</li> <li>If a human_readable_func is given the value and levels are converted with this function</li> <li>If a unit is given it is append to the value and each level.</li> </ul> Be aware: Every builtin human_readable_func already provides a unit. Thus the unit is not needed in general. There may be situations where a human_readable_func which provides a unit AND an additional unit info is useful, eg. when a bytes rate is calculated. In this case the service details should display "23.5 B/s" whereby C+ unit="/s", human_readable_func=get_bytes_human_readable, C- If you use this API function {{check_levels}} in your check plugins you possibly need to adapt your check plugin functions. Otherwise duplicate unit infos may be displayed or there are missing titles ({{infoname}}).

Check_MK Werk 7224: Backup/Restore: Fix vanishing files terminating a backup

by Lars Michelsen

ID: 7224 Title: Backup/Restore: Fix vanishing files terminating a backup Component: Site Management Level: 2 Class: Bug fix Version: 1.6.0i1 The "omd backup" mechanism recursively backups all site related files of a Check_MK site. When files in a site directory, that is currently being processed vanish, this could lead to failed backups with errors like this: C+: Site backup failed: Traceback (most recent call last): File "/omd/versions/1.5.0p8.cee/bin/omd", line 4553, in command_function(args, command_options) File "/omd/versions/1.5.0p8.cee/bin/omd", line 3711, in main_backup backup_site_to_tarfile(fh, tar_mode, options) File "/omd/versions/1.5.0p8.cee/bin/omd", line 3686, in backup_site_to_tarfile backup_site_files_to_tarfile(tar, options) File "/omd/versions/1.5.0p8.cee/bin/omd", line 3556, in backup_site_files_to_tarfile tar.add(g_sitedir, g_sitename, exclude=filter_files) File "/omd/versions/1.5.0p8.cee/lib/python2.7/tarfile.py", line 2032, in add recursive, exclude, filter) File "/omd/versions/1.5.0p8.cee/lib/python2.7/tarfile.py", line 2032, in add recursive, exclude, filter) File "/omd/versions/1.5.0p8.cee/lib/python2.7/tarfile.py", line 2032, in add recursive, exclude, filter) File "/omd/versions/1.5.0p8.cee/lib/python2.7/tarfile.py", line 2032, in add recursive, exclude, filter) File "/omd/versions/1.5.0p8.cee/lib/python2.7/tarfile.py", line 2032, in add recursive, exclude, filter) File "/omd/versions/1.5.0p8.cee/lib/python2.7/tarfile.py", line 2009, in add tarinfo = self.gettarinfo(name, arcname) File "/omd/versions/1.5.0p8.cee/lib/python2.7/tarfile.py", line 1881, in gettarinfo statres = os.lstat(name) OSError: [Errno 2] No such file or directory: '/omd/sites/xyz/var/pnp4nagios/perfdata/hastenichgesehn/Interface_BG4_2OG_VLAN_421.xml.new' C-: After this change the backup continues in such a situation excluding the just vanished file.
