Check_MK Werk 6240: WATO Web-API: Implemented SLA API interface

by Andreas

ID: 6240 Title: WATO Web-API: Implemented SLA API interface Component: WATO Level: 1 Class: New feature Version: 1.6.0i1 SLA data for services can now be fetched via the Web API. The new action is named <tt>get_sla</tt>. The request object is structured like this: F+: { "query": [ [[{sla_configuration}], [{timerange_spec_1}], [{host/service pair}]] ] } F-: A query entry always consists of 3 fields. <ul> <li>The list of sla_definitions</li> <li>The list of timerange specificiations</li> <li>The list of host/service pairs</li> </ul> The sla_definition is simply the id of the configured SLA definition. The timerange specification has some special syntax Some examples: F+: # # Field to send in query # "Today" # "d0" # "Yesterday" # "d1" # # "This week" # "w0" # "Last week" # "w1" # # "This month" # "m0" # "Last month" # "m1" # # "This year" # "y0" # "Last year" # "y1" # # "The last..." # "last:86400" # "Time range" # "range:1530271236:1530281236" # # SLA configurations have no distinct timestamp. The timestamp depends on the SLA period # The following example says # - Start at the penultimate sla period (Note: 0 is current period) # - Look back additional 4 sla periods # There will be 5 period results # "Sla period range" # "sla:2:4" F-: The of host/service pairs identifies the required services. A valid request may look like F+: { "query": [ [["sla_configuration_1"], ["w1"], [["HostA", "ServiceB"]]] ] } F-: This queries the sla_configuration_1 with the timerange "Last week" for the service HostA/ServiceB. This returns 1 result. As you might have noticed, each field in the query is enclosed by a list. That's because each query entry may have multiple values specified. F+: { "query": [ [["sla_configuration_1", "sla_configuration_2"], ["w1"], [["HostA", "ServiceB"]]] ] } F-: This queries the sla_configuration_1 and sla_configuration_2 with the timerange "Last week" for the service HostA/ServiceB. This returns 2 results. Now add an additional timerange specification F+: { "query": [ [["sla_configuration_1", "sla_configuration_2"], ["w1", "w0"], [["HostA", "ServiceB"]]] ] } F-: This queries the sla_configuration_1 and sla_configuration_2 with the timerange "Last week" and "This week" for the service HostA/ServiceB. This returns 4 results. Finally, you can also add additional triples to the query. F+: { "query": [ [["sla_configuration_1"], ["w1"], [["HostA", "ServiceB"]]], [["sla_configuration_2"], ["w0"], [["HostX", "ServiceY"]]] ] } F-: This queries sla_configuration_1 with the timerange "Last week" for HostA/ServiceB and sla_configuration_2 with the timerange "This week" for HostX/ServiceY. The returned result for these queries is a python dictionary with lots of infos F+: {'mysite': {'myhost': {'CPU load': {(('myhost', 'CPU load'), 'sla_configuration_1', ('sla_period_range', (0, 1)), 'weekly'): {'plugin_results': [{'period_results': [{'duration': 604800.0, 'sla_broken': False, 'statistics': {'duration': {-1: 604800.0}, 'percentage': {-1: 100.0}}, 'subresults': [{'deviation_info': {'deviation': 0.0, 'deviation_state': 2, 'levels': (0, 0), 'limit': 0.0}, 'error_instances': [], 'requirement': (0, 'min', 0.0), 'sla_broken': False}], 'timerange': (1529272800.0, 1529877600.0)}, {'duration': 396134.0, 'sla_broken': False, 'statistics': {'duration': {-1: 385358.0, 0: 10776}, 'percentage': {-1: 97.27970838150726, 0: 2.7202916184927326}}, 'subresults': [{'deviation_info': {'deviation': 2.7202916184927326, 'deviation_state': 0, 'levels': (0, 0), 'limit': 0.0}, 'error_instances': [], 'requirement': (0, 'min', 0.0), 'sla_broken': False}], 'timerange': (1529877600.0, 1530273734)}], 'plugin_id': 'service_state_percentage', 'timerange_sla_duration': 1000934.0}], 'sla_id': 'sla_configuration_1', 'sla_period': 'weekly'}}}}} F-: Keep in mind that this API implementation is an initial version, so there might be interface changes within the next months.

Check_MK Werk 6116: mk_db2.linux: major refactoring of the plugin to solve different issues

by Tom Baerwinkel

ID: 6116 Title: mk_db2.linux: major refactoring of the plugin to solve different issues Component: Checks & agents Level: 1 Class: Bug fix Version: 1.5.0i2 The refactoring solves the following known issues: 1. Here documents are avoided which should resolve wrong output due to quoting problems. 2. Fix the calculation of the number of database connections. 3. Use a more accurate method to calculate the latency for a database connection. 4. The structure of the plugin was improved for better maintainability. To use the new version of the plugin it has to be deployed to to the affected hosts. Futhermore, the script is now required to be accessible and executable by the instance users to work properly.

Check_MK Werk 5966: Unified mk_oracle and mk_oracle.aix

by Simon Betz

ID: 5966 Title: Unified mk_oracle and mk_oracle.aix Component: Checks & agents Level: 1 Class: New feature Version: 1.6.0i1 The agent plugin {{mk_oracle.aix}} does not exist anymore. Instead the {{mk_oracle}} plugin was refactored and now supports AIX, too. In order to use the new plugin please install it to the well-known agent plugin path or use the agent bakery if you have a enterprise edition. The new option '--log' logs some steps to the related log file which can be found in {{$MK_VARDIR/log/mk_oracle.log}} and helps to find any errors. Please note that the shell command 'flock' has to be installed.

Check_MK Werk 6224: Prevent multiple mkeventd's from being started in some situations

by Konstantin Büttner

ID: 6224 Title: Prevent multiple mkeventd's from being started in some situations Component: Event Console Level: 1 Class: Bug fix Version: 1.6.0i1 In rare circumstances, a non-responsive mkeventd process would stick around after an OMD restart, and the new one would not be aware of the other one's existance due to duplicated cleanup of the PID file in the Event Console's init script and the process itself respectively. We remove the cleanup in the init script, as it is more coarse.
