[checkmk-commits] 5338 fileinfo: date variables can be defined in fileinfo.cfg

Module: check_mk Branch: master Commit: bff8c88142c5059ef1a92caaa618cee6925ec087 URL: http://git.mathias-kettner.de/git/?p=check_mk.git;a=commit;h=bff8c88142c505… Author: Tom Baerwinkel &lt;tb(a)mathias-kettner.de&gt; Date: Fri Sep 29 09:59:06 2017 +0200 5338 fileinfo: date variables can be defined in fileinfo.cfg This werk adds the possibility to define date variables in the file fileinfo.cfg either directly or via the corresponding rule Count, size and age of files. Date variables can be used on linux and solaris hosts and have the form $DATE:format-spec$ where format-spec is a list of time format directives of the unix date command. Example: $DATE:%Y%m%d$ is todays date in the format YYYYMMDD. Using this option the agent will only send files containing the current date. Date variables can be used together with the rules File Grouping Patterns and Size, age count of file groups to monitor if files are created in a directory on a dayly basis. Note that the option Only check during the folling times of the day should be set. Otherwise a warning may be displayed if the file of the current day is not present yet.
