Formatting snmp_check sysUpTime output
Hi EE peeps,
I've got a 3Com switch and I'm setting up Nagios to monitor it. I'm in the early stages of this and have got Nagios pulling the up time off the switch. So far I've done/got the following;
Is there a way of just getting the days value of out this result so I can then set warning and critical levels?

SNMP OK - Timeticks: (338739470) 39 days, 4:56:34.70 |

awk { print $6 }

So the command would look like the following;
check_snmp -H 192.168.0.252 -C public -o sysUpTime.0 awk { print $6 }
Sorry, hit submit too quickly.
You need to play with "awk", it will do what you want. For example, lets say you output your SNMP return into a file called "xx" so the contents of "xx" are:
SNMP OK - Timeticks: (338739470) 39 days, 4:56:34.70
Then you could enter:
cat xx | awk -F' ' '{print $6}'
and "39" would be returned because "39" is the 6th column separated by spaces.
So you need to pipe your output into awk to get the "days" number.
Good luck,
Steve

check_snmp -H 192.168.0.252 -C public -o sysUpTime.0 | awk F` ` `{ print $6 }`
You need a "pipe" after the check_snmp command
Test it . . .

Tried and got this;
rs3@RS3:/usr/lib/nagios/pl
SNMP OK - Timeticks: (348345677) 40 days, 7:37:36.77 |
rs3@RS3:/usr/lib/nagios/pl
-bash: command substitution: line 2: syntax error: unexpected end of file
rs3@RS3:/usr/lib/nagios/pl
Am I doing something a bit thick?

Hi Steve,
That worked, though I looked up awk on t'internet (never used awk before - hangs head in shame) and tweeked it a little;
Cheers for that!
