Check_MK Werk 8642: Reworked logging configuration of the Check_MK Microcore

by Lars Michelsen

ID: 8642 Title: Reworked logging configuration of the Check_MK Microcore Component: The Check_MK Micro Core Level: 1 Class: New Feature Version: 1.4.0i3 The logging configuration of the Check_MK Microcore has been reworked to be configured in a single setting. The log levels have been unified for all these log domains. Thes configuration options have been deprecated: <ul> <li><tt>cmc_log_level</tt>: Logging</li> <li><tt>cmc_livestatus_debug</tt>: Logging of Livestatus queries</li> <li><tt>cmc_debug_alerts</tt>: Logging of the alert processing in the core</li> </ul> The attribute <tt>log_level</tt> has been removed from <tt>cmc_log_cmk_helpers</tt> which is now only used to toggle the debug mode of the Check_MK helpers. The new option is <tt>cmc_log_levels</tt> (Logging of the core). The incompatibility is that, if you have configured custom log leves with the options mentioned above before, they are not effective anymore. You will have to set the log levels again using the new option. In most cases it should be no problem that the log levels are reset, because they are mostly only used for a short time during debugging actions.

Check_MK Werk 8580: Removed space leaks related to dynamic columns.

by Sven Panne

ID: 8580 Title: Removed space leaks related to dynamic columns. Component: Livestatus Level: 1 Class: Bug Fix Version: 1.4.0i3 When some special columns were queried via Livestatus, the monitoring core leaked memory. This affected the following columns: <ul> <li><tt>mk_logwatch_file</tt> in table <tt>hosts</tt></li> <li><tt>value</tt> in table <tt>eventconsolereplication</tt></li> <li><tt>rrddata</tt> in tables <tt>hosts</tt> and <tt>services</tt></li> </ul>

Check_MK Werk 8643: Web API: New API for fetching graph data

by Lars Michelsen

ID: 8643 Title: Web API: New API for fetching graph data Component: Metrics System Level: 1 Class: New Feature Version: 1.4.0i3 The raw data of the Check_MK graphs can now be fetched via the Web API. The new action is named <tt>get_graph</tt>. The request object is structured like this: C+: { "specification": [..., ...], "data_range": { "time_range" : [..., ...], } } C-: The specification is using the Check_MK internal graph specification format. The first element is the specification type (<tt>template</tt>, <tt>custom</tt> or <tt>explicit</tt>. The structure of the second element depends on the type. Please take a look at the examples below to get an idea of it. The time range is given in two unix timestamps, the start time and the end time. For example this command can be used to fetch the first graph of the Check_MK service of the host myhost123: C+: # curl "http://mycmkserver/mysite/check_mk/webapi.py?action=get_graph&_username=aut…" -d 'request={"specification": ["template", {"service_description": "Check_MK", "site": "mysite", "graph_index": 0, "host_name": "myhost123" }], "data_range": {"time_range": [1480653120, 1480667520]}}' C-: The answer may look like this: C+: { "result": { "step": 60, "start_time": 1480653120, "end_time": 1480667520, "curves": [ { "color": "#87f058", "rrddata": [null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, null, 0.05, 0.059, 0.0423333, 0.0488333, 0.0413333, 0.0573333, 0.0515, 0.05, 0.05, 0.05, 0.05, 0.058, 0.052, 0.0578333, 0.0365, 0.0453333, 0.0576667, 0.0525, 0.05, 0.0573333, 0.0526667, 0.0428333, 0.0471667, 0.05, 0.05, 0.05, 0.05, 0.05, 0.05, 0.05, 0.05, 0.0436667, 0.0526667, 0.06, 0.06, 0.054, 0.05, 0.0558333, 0.0541667, 0.0556667, 0.049, 0.0455, 0.0553333, 0.0493333, 0.04, 0.0451667, 0.05, 0.05, 0.05], "line_type": "stack", "title": "CPU time in user space" }, ] }, "result_code": 0 } C-: This command is used to fetch the data of a custom graph named <tt>custom_graph_1</tt>: C+: # curl "http://mycmkserver/mysite/check_mk/webapi.py?action=get_graph&_username=aut…" -d 'request={"specification": ["custom", "custom_graph_1"], "data_range": {"time_range": [1480653120, 1480667520]}}' C-:

Check_MK Werk 8579: Generalize Livestatus filter operators

by Sven Panne

ID: 8579 Title: Generalize Livestatus filter operators Component: Livestatus Level: 1 Class: New Feature Version: 1.4.0i3 Previously, some filter operator did not work for numbers or had only a special meaning with certain columns. This has been generalized in a uniform way, so all operators work for numbers now, too. The operators <tt>~</tt>, <tt>=~</tt>, and <tt>~~</tt> interpret numbers as bit sets, and have the following meaning: <ul> <li><tt>x ~ y</tt> means: <tt>x</tt> is a superset of <tt>y</tt></li> <li><tt>x =~ y</tt> means: <tt>x</tt> is a subset of <tt>y</tt></li> <li><tt>x ~~ y</tt> means: <tt>x</tt> contains at least one element of <tt>y</tt></li> </ul> This is consistent with the way attribute list columns work and makes the Livestatus semantics more regular.

Check_MK Werk 8672: Fixed crash of monitoring core with duplicate hosts

by Sven Panne

ID: 8672 Title: Fixed crash of monitoring core with duplicate hosts Component: The Check_MK Micro Core Level: 1 Class: Bug Fix Version: 1.4.0i3 When host names were not unique, the Check_MK micro core crashed when the "hostgroups" or "servicegroups" table was queried via Livestatus. This has been fixed now. Note that such a configuration is invalid, but due to another bug (in cmk), it was possible to generate it nevertheless.
