cut output in 2 pieces

[menno]

hi there

i enabled snmp on my qnap nas
i can read the HDD temperatures but....

the output is like this : 40¢XC/104¢XF

i just want the first 2 chars. (so 40)
thats the temperature from my disk inside my NAS

can youplease tell me how to remove the other chars and leave only the first 2 intact ?

many thanks
m

ps. the OID for disk 1 = .iso.org.dod.internet.private.enterprises.24681.1.2.11.1.3.1

You cannot remove some characters.
Normally SNMP agent should provide another counter that returns temperature value as a number. Do you have MIB file for this device?

yes my qnap nas can create a MIB file.
but mibbrowser cant't hndle this file

Its better to send files by e-mail to support@ks-soft.net
Looks like your SNMP agent does not provide integer counters. Strange.. normally SNMP agents should provide information to other programs so they should be designed to provide data in some machine-usable form.
