check_files.vbs – external script to be used with nsclient

Project Notes

check files under a given path

uses NagiosPlugin.vbs from nsclient++/scripts/lib
- NagiosPlugin.vbs which came with nsclient++ vers. 0.3.9 (earlier version needed adaptation)
- compares bounds to double values, so 10 comes after 9 (numeric sorting)
- bounds definition conforms to nagios plugin guidelines (http://nagiosplug.sourceforge.net/developer-guidelines.html#THRESHOLDFORMAT)

10 < 0 or > 10, (outside the range {0..10})
10: < 10, (outside {10 .. 8})
~:10 > 10, (outside the range of {-8 .. 10})
10:20 < 10 or > 20, (outside the range {10..20})
@10:20 >= 10 and <= 20, (inside the range {10..20})
critical: threshold critical
namefilter: regular expressionon on which files have to match
age: files have to be older/newer (see selage) than age

selage: older/newer/hour/ignore
older/newer: count only files if the are older/newer

ignore: count files independent of their age
searchdepth: search down x subdirs (searchdepth:1 - do not go down in directory hierarchy)
seldat: modified/created

size: if file is smaller than given size give a warning
expectmatch: if less than expectmatch files correspond to namefilter give a warning
weekdays:
if selage:hour files have to be written only on weekdays (1:sunday, 2:monday, ...)
if selage:newer or selage:older and the timeunit of age is d (days), we add as many days to age as the last weekday is back
