Re: Need help with illogical "exec"-behaviour!

Hallo again!

1. Thomas, you're right! But I testet this with net-snmp 5.2 and 5.3 -> 
the same again:

        NET-SNMP with diskio            ->  "exec" doesn't work correct 
(look beneath)
        NET-SNMP without diskio ->  "exec" work's fine

2. Sorry, the first configure-command in my first mail wasn't the real 
original suse one.
    Suse doesn't include ucd-snmp/diskio, but I NEED TO INCLUDE IT! :-(

You shouldn't be using something as old as ucd-snmp 4.2.5. We highly 
recommend to install our latest release (5.3) instead.

Hallo everybody! 

I've a problem with the „exec“-command on ucd/net-snmp! 
I've added the following command to the snmpd.conf: 

exec .1.3.6.1.4.1.2021.50 cpuload /usr/share/snmp/cpu 

„cpu“ is a own C-program which calculates the cpu-load in percent for each 
cpu out the counters in /proc/stat. Each time the program ist called, it 
takes the difference between the actual counters-stats and the 
counter-stats in a temp-file which was made at the last execution. 
So far, so good! As you can see, the program work's fine when you execute 
it in a shell! It detects 8 CPU-entries in /proc/stat and puts out 8 
values. 

And now my problem: 

I've recompiled the original Suse ucd-snmp *.rpm the get the 
ucd-snmp/diskio-MIB inside it. And when I call .1.3.6.1.4.1.2021.50 the 
output is something like that one you can see beneath. Snmpd doesn't 
display the float-values. Instead of the float-values you only have „0.00“ 
or „nan“ or „-inf“. 
But with the ORIGINAL Suse *.rpm it WORKS! Beneath you can see the two 
./configure commands. The first one is from the Suse *.rpm and the second 
one is mine. 

Does anybody have an idea what this illogical thing could be? 

About an answer I would be pleased really much! 

greetings 
Tommy
