[rancid] Eliminating two lines from foundry output

Discussion:

Hello,

I am a happy user of rancid for my Foundry switches (except the EdgeIron
line, which needs support, but I haven't worked on that yet), but have
become annoyed in the past weeks because I get an email nearly every
time rancid checks one switch. It is because it displays the temp.
Here is the output:

+ ! Fan controlled temperature: 35.5 deg-C

! Fan speed switching temperature thresholds:

! Speed 2: 25<----->40 deg-C

My problem is that I want to eliminate the "Fan controlled temperature
lines" so I don't get an email every 1/2 hour (as I have rancid
configured to poll).

Any thoughts on how to do this?

Thanks,

Chris

Chris,

This is a fairly simple modification to francid.

I don't have a Foundry handy to figure this out but the following steps
should get you there quickly.

open francid with an editor and find the line that starts with
@commandtable
After this are the commands run on the switch followed by the name of
the subroutine that processes the output.

Find the name of the subroutine that processes the output you want to
eliminate and modify that subroutine to skip the desired line.

If my guesses are right, you will find the following line which
eliminates TEMPERATURE output but doesn't match on this specific switch:

if (/(POWERS|TEMPERATURE READINGS)/) {

You can add 'temperature' to this line like:

if (/(POWERS|TEMPERATURE READINGS|temperature)/) {

Or otherwise modify the subroutine to skip this output.

Good luck,

Mike

That did the trick, though I have one other trick I need to pull out of
my sleeve (after I learn it).

I still am getting config changes, even though nothing actually changes...

Exerpt:

- ! Fan 1 ok, speed (auto): 1<->2<->[[3]]
- ! Fan 2 ok, speed (auto): 1<->2<->[[3]]
+ ! Fan 1 ok, speed (auto): 1<->[[2]]<->3
+ ! Fan 2 ok, speed (auto): 1<->[[2]]<->3

What I want to do is preserve the "Fan X ok" or "Fan X failed", but with
out the fan speed information. Why? Because the temperature hangs
right at the threshold between the two fan speeds, so it goes up and
down several times per day.

Is there a way to be that granular in my string processing without
bogging everything down?

Chris
