Check_MK Werk 0338: Introduce time limit on availability queries

by Mathias Kettner

ID: 0338 Title: Introduce time limit on availability queries Component: Reporting & Availability Level: 2 Class: Bug Fix Version: 1.2.5i1 The availability view now imposes an upper limit on the execution of the underlying livestatus query. The default is 30 seconds. This can be configured in the reporting options. This limit keeps the system usable in situations where a query over a long time range would need a very long time to execute.

Check_MK Werk 0337: New header for limiting the execution time of a query

by Mathias Kettner

ID: 0337 Title: New header for limiting the execution time of a query Component: Livestatus Level: 1 Class: New Feature Version: 1.2.5i1 The new Livestatus header Timelimit: sets an upper limit for the execution time of a query. Specify the timeout as a number of seconds. The following query will stop after 5000 lines of output. If that takes longer than 30 seconds, then the query <b>fails with no output</b>: F+:query.lql GET log Columns: message Timelimit: 30 Limit: 5000 F-: Please note, that <tt>Limit:</tt> and <tt>Timelimit:</tt> have a different behaviour when the limit is reached: <li class=list><tt>Limit:</tt> end the query, output all rows that have been found so far.</li> <li class=list><tt>Timelimit:</tt> abort the query with an error, do not output any lines.</li>

Check_MK Werk 0336: Limit the number of lines read from a single logfile

by Mathias Kettner

ID: 0336 Title: Limit the number of lines read from a single logfile Component: Livestatus Level: 2 Class: Bug Fix Version: 1.2.5i1 If for some reason you have very large history logfiles with millions of entries then Livestatus would consume large amounts of memory while parsing these when you access the <tt>log</tt> table. This could lead to a hanging system or even a crash. In order to avoid such situations the number of lines that are read from each individual file are now limited. The default limit is one million lines. You can change this default by defining the variable <tt>max_lines_per_logfile/tt> in your <tt>nagios.cfg</tt>. The following example sets the maximum number to 20 million lines: F+: broker_module=/some/path/livestatus.o max_lines_per_logfile=20000000 ... F-: When using the Check_MK Micro Core the configuration can be done via WATO global setting <i>Maximum number of parsed lines per log file</i>.
