Monitoring absense of bandwidth

[Giorgio Zarrelli]

Easy and brilliant :-)

Anyway:

Table 3. Example ranges

Range definition

Generate an alert if x...

10	< 0 or > 10, (outside the range of {0 .. 10})
10:	< 10, (outside {10 .. ∞})
~:10	> 10, (outside the range of {-∞ .. 10})
10:20	< 10 or > 20, (outside the range of {10 .. 20})
@10:20	≥ 10 and ≤ 20, (inside the range of {10 .. 20})
10	< 0 or > 10, (outside the range of {0 .. 10})
Table 4. Command line examples

Command line

Meaning

check_stuff -w10 -c20	Critical if "stuff" is over 20, else warn if  
over 10 (will be critical if "stuff" is less than 0)
check_stuff -w~:10 -c~:20	Same as above. Negative "stuff" is OK
check_stuff -w10: -c20	Critical if "stuff" is over 20, else warn if  
"stuff" is below 10 (will be critical if "stuff" is less than 0)
check_stuff -c1:	Critical if "stuff" is less than 1
check_stuff -w~:0 -c10	Critical if "stuff" is above 10; Warn if  
"stuff" is above zero
check_stuff -c5:6	The only noncritical range is 5:6
check_stuff -c10:20	Critical if "stuff" is 10 to 20

Ciao,

Giorgio
