RE: [Devmon] Printer toner monitoring/dhcp monitoring

[Schwimmer, E. E *H. <EE...@hs...>]

Hrm, I have some revervations about implementing logical code
inside of the templates (regular expression substitution was bad
enough).  You might be able to get away with something similar to
what I did in the apc-9619 environmental test.  The humidity test
sometimes just doesn't work, and returns a negative number.  So
I duplicated the oid using the MATH transform, and then used
the threshold message to set 'n/a' if it was lower than 0,=20
or the value of the original oid, if it was above zero.

The problem here is that you might run out of threshold colors.

This MIGHT work:

In your transforms file:=20
{newTonerLevel} : MATH  : {origTonerLevel}
{toner}         : WORST : {origTonerLevel} {newTonerLevel}

In your thresholds file:
{newTonerLevel}  : red     : -2   : Unknown
{newTonerLevel}  : yellow  : -3   : Some remaining supply
{newTonerLevel}  : green   : -1   : No restrictions on this parameter

{origTonerLevel} : red     : <5   : Toner is very low.
{origTonerLevel} : yellow  : <15  : Toner is low.
{origTonerLevel} : green   : >=3D15 : Toner is okay.

In your messages file:
Toner level : {toner.color} {toner}

Ugh.  That is ugly.  I'll have to think about how to handle this.
Something similar should work for your dhcp addresses if you need
a quick fix before I figure out how to deal with this.

Used the attached patch to fix the complaints about non-numeric
values in a numeric comparison.
