RE: [Karlnet] Karlnet 4.31 - MIB MRTG help - SNR FOR sats!!!

[Peter Dordik <dordik@presov.viapvt.sk>]

Hi,

i think, that more important SNR values are from ISP Base, but there is a 
problem with changing order of satellites in SNMP tree after reboot of ISP 
Base. We can not use fixed last "NUMBERS" in mrtg.cfg.

So, here is my VERY DIRTY script, I use.

Regards
        Peter

#!/bin/sh

#  Signal/Noise ISP Base script example for MRTG

#  usage: /usr/local/bin/sn ip_of_isp_base sat_name name_of_read_comunity

NUMBER=`/usr/local/bin/snmpwalk $1 $3 .1.3.6.1.4.1.762.2.5.2.1.3  | /bin/grep 
$2 | /usr/bin/cut -c 27-28`

/usr/local/bin/snmpget $1 $3 .1.3.6.1.4.1.762.2.5.2.1.8.$NUMBER | /usr/bin/cut -

mrtg.cfg example:
