Check_MK Werk 0973: Renaming of hosts via WATO

by Mathias Kettner

ID: 0973 Title: Renaming of hosts via WATO Component: WATO Level: 2 Class: New Feature Version: 1.2.5i3 WATO has now a new function Rename Host. You will find a button with that name in the Properties of a host. It allows a renaming of an existing host. Before you can use that feature you need to have all changes activated, so nothing is pending. Renaming a host is a complex precedure that will not only rename the host in WATO, but also in: <ul> <li>all rules from Host & Service Parameters</li> <li>cluster's node definitions</li> <li>a host's parent definitions</li> <li>Business Intelligence rules</li> <li>notification rules (both rule based and flexible notifications)</li> <li>internal Check_MK data like caches and performance counters</li> <li>auto-disovered services of the host</li> <li>logfile information of logwatch plugin</li> <li>stored SNMP walks</li> <li>RR databases with performance data</li> <li>RRD updates in journal of RRD Cache</li> <li>spool files of PNP4Nagios</li> <li>NagVis maps</li> <li>monitoring history entries (events and availability)</li> <li>the current monitoring state (including ackowledgements and downtimes)</li> </ul> Please note that renaming of a host involves a temporary stop of the monitoring core. This is neccessary in order to avoid situation where the old and the new name of a host is being used at the same time.

Check_MK Werk 1409: Extended Check_MK-API: check function may return None

by Mathias Kettner

ID: 1409 Title: Extended Check_MK-API: check function may return None Component: Checks & Agents Level: 2 Class: New Feature Version: 1.2.5i6 A check function may now return <tt>None</tt> (or simply end without returning anything). This will no longer create an exception but return state <tt>UNKNOWN</tt> and - depending on the type of the check - one of the following outputs: <tt>Item not found in SNMP data</tt> <tt>Item not found in agent output</tt> This means that for the typical check that loops through the agent output looking for its item now does not need to manually do a C+: return 3, "Something not found in agent output" C-: anymore. This is now the default case. This has several advantages: <ul> <li>You save some code in the check implementation.</li> <li>The output of the various checks is unified.</li> <li>A future Check_MK version can easily have a rule for changing the state in such cases from UNKNOWN to WARN or CRIT.</li> </ul>

Check_MK Werk 1408: mknotifyd now really reads all configuration files below mknotifyd.d

by Mathias Kettner

ID: 1408 Title: mknotifyd now really reads all configuration files below mknotifyd.d Component: Notifications Level: 2 Class: Bug Fix Version: 1.2.5i6 Previously the notification spooler daemon <tt>mknotifyd</tt> just read the single file <tt>etc/check_mk/mknotifyd.d/wato/global.mk</tt>. Now it reads all files below <tt>etc/check_mk/mknotifyd.d</tt> - just as one would expect. Note: there is still no <tt>etc/check_mk/mknotifyd.mk</tt> file.

Check_MK Werk 1406: Assume PEND in count_ok aggregations if all nodes are PEND

by Mathias Kettner

ID: 1406 Title: Assume PEND in count_ok aggregations if all nodes are PEND Component: BI Level: 2 Class: New Feature Version: 1.2.5i6 If you are using the BI aggregation function <tt>count_ok</tt> then nodes with the state <tt>PEND</tt> (which essentially means unmonitored or not present) are handled differently from now. If all nodes are pending then the total state will also be pending. If just some of the nodes are pending then they will not taken into account. This is especially imported when doing availability computations on BI aggregates.

Check_MK Werk 1405: Checkbox for settings downtimes on the hosts of the selected services

by Mathias Kettner

ID: 1405 Title: Checkbox for settings downtimes on the hosts of the selected services Component: Multisite Level: 2 Class: New Feature Version: 1.2.5i6 In the Multisite command box for setting downtimes on services there is now a new checkbox called Schedule downtimes on the affected hosts instead of their services. When you check this then the scheduled downtimes are set on the hosts of the selected services rather then on the services themselves. Note: When a host is in scheduled downtime then all its services are considered to be in a scheduled downtime, as well. There is no need to set a downtime on these.

by Andreas Boesl

ID: 1117 Title: agent_vsphere: now able to query license information from esx system Component: Checks & Agents Level: 2 Class: New Feature Version: 1.2.5i6 The agent_vsphere is now able to get the license usage from the LicenseManager instance. Upon inventory each license will lead to an own check name esx_licenses. The check parameters (absolute used, percentage used, all used) can be configured via the WATO rule <tt>Number of used VMware licenses</tt>

Check_MK Werk 1403: kernel.util: allow levels for the total CPU utilization

by Mathias Kettner

ID: 1403 Title: kernel.util: allow levels for the total CPU utilization Component: Checks & Agents Level: 2 Class: New Feature Version: 1.2.5i6 The CPU utilization check for Linux only allowed to set levels for the disk wait percentage. The parameters have been converted to a dictionary and now allow to set levels on the total CPU utilization as well. Please note: if you have defined the variable {kernel_util_default_levels} in your {main.mk}, then you need to convert this to a dictionary - otherwise it will be ignored. Instead of F+:main.mk kernel_util_default_levels = (10, 20) F-: ... please now write...: F+:main.mk kernel_util_default_levels = { "iowait" : (10, 20) } F-: Users of WATO are not affected by this and do not need to change anything.
