问题
I have to go through and collect a few OIDs from some SNMP enabled network printers with a BASH script I have been working on.
My Request:
snmpget -v2c -c public 192.168.0.77
.1.3.6.1.2.1.1.1
.1.3.6.1.2.1.1.2
My Actual Response:
.1.3.6.1.2.1.1.1 = Counter32: 1974
.1.3.6.1.2.1.1.2 = Counter32: 633940
The Desired Response:
1974
633940314
(just the oid values only)
I looked and tested several options using the resource from the site below:
http://www.netsnmp.org/docs/man/snmpcmd.html#lbAF
-Oq removes '=' so running
snmpget -v2c -c public -Oq 10.15.105.133
.1.3.6.1.2.1.1.1
.1.3.6.1.2.1.1.2
returns
.1.3.6.1.2.1.1.1 Counter32: 1974
.1.3.6.1.2.1.1.2 Counter 32: 633940314
so I know I am phrasing my request properly.
I am taking the values and writing them to a MYSQL dB, I set the data types in my tale schema, the request is consistent so I know the definition of the OID, so I do not need all the information I am getting back, just the value of the OID itself, so I can write it to my dB without manipulating the the response. I probably can manipulate the response pulling the information to the right of ":" and writing the value of the OID.
I am relatively new to SNMP (http://www.net-snmp.org/), but I can not see why this is not a more commonly asked question because I have been searching everywhere for an answer and this post is my last recourse...
回答1:
You can tune the output with the -O argument:
snmpgetnext -Oqv -v 2c -c public 192.168.0.77 .1
2
See the --help:
q: quick print for easier parsing
v: print values only (not OID = value)
回答2:
You can postprocess the output with a simple Awk or sed script, or even just grep (provided you have grep -P).
snmpget -v2c -c public 192.168.0.77 <<'____HERE' | awk '{ print $4 }'
.1.3.6.1.2.1.1.1
.1.3.6.1.2.1.1.2
____HERE
or
.... | sed 's/.*: //'
or
.... | grep -oP ':\K[0-9]+'
