Summary: check_swap 1.4beta1 on AIX: crit,warn args swapped

Initial Comment:
on AIX 3.4, using nagios-plugins-1.4beta1 tarball:

   check_swap -a -w 50% -c 75%

Yields:

   Warning percentage should be more than critical 
percentage

on Solaris and Linux, the command works as expected.

Ahh, I finally understand. There was a change to check_swap 
to make it more consistent. The old 1.3 release help says this:

---
 -w, --warning=INTEGER
   Exit with WARNING status if less than INTEGER bytes of 
swap space are free
 -w, --warning=PERCENT%
   Exit with WARNING status if more than PERCENT of swap 
space has been used
---

Note the switch between checking against free swap for 
absolute numbers, but against used for %. So the new 1.4 
release considers the thresholds the same way. This also 
makes it more consistent with check_disk.

I've also noticed that the help file for check_swap is wrong, 
so I'll update that now.

You are right in pointing this out. Will get some text put 
together about the significant changes between 1.3 and 1.4, 
including syntax breakages like this.

I'll leave this open for now.

P.S. What is your full name? I can then add it to our list of 
people to thank.

I thought so too, but the same command under version 1.3 of 
check_swap on Solaris executes just fine.  Syntax change?  Bug?

I don't think this is a problem; check_swap checks the 
amount of free space so critical must be lower than warning, 
hence the error message. 

Unless I am missing something?

I will mark this call into pending state.

Mea culpa.  The problem exists on Solaris as well.  I imagine 
Linux will have the problem as well.

I've just tried this on Solaris and I get "Warning percentage 
should be more than critical percentage". Have you done a 
make clean on Solaris and Linux?
