Sometimes you need to alter the output you get from a command.

Divide Results

Using awk you can get the values and divide them by a number (like 1000) and then print out the adjusted values.

This command produces the default output of:

Command:

./check_snmp -H ups01 -C box293 -o 1.3.6.1.4.1.318.1.1.1.4.2.3.0

Output:

SNMP OK - 13 | iso.3.6.1.4.1.318.1.1.1.4.2.3.0=13

Using awk I can change "13" to "0.013"

Command:

./check_snmp -H ups01 -C box293 -o 1.3.6.1.4.1.318.1.1.1.4.2.3.0 | awk -F'|' '{split($1,array_left,"-");} {split($2,array_right,"=");} {print array_left[1]"- "array_left[2]/1000"|"array_right[1]"="array_right[2]/1000;}'

Output:

SNMP OK - 0.013| iso.3.6.1.4.1.318.1.1.1.4.2.3.0=0.013
