I have several monitoring scripts that pull SNMP stats off of switches and
routers that I have used for the past 10 years using perl by running snmpget
and parsing the program output into variables:
Ex:
===
open(GETIN, "/usr/bin/snmpget -Oqf -v2c -c public 192.168.1.20
interfaces.ifTable.ifEntry.ifInOctets.1 |");
(@temp) = split(/\s+/, <GETIN>);
$inBytes = $temp[$#temp];
===
Pretty rough, but it's worked for us for over 10 years.
I have decided to torture myself by learning to use Net::SNMP instead of
modifying our older scripts for pulling stats off of some of our newer
equipment.
The purpose is to create a comma delimited file of statistics from these
devices (satellite modems). I have created the array of OID values to retrieve,
and have pulling the info from the device, but have hit a bit of a roadblock in
my understanding on parsing the output to get the returned values.
Here is what I have sofar:
-------------------------------------------------
#!/usr/bin/perl
use Net::SNMP;
$SNMP_COMMUNITY = "public";
$SNMP_VERSION = "2";
$VSAT_ANCH_IP = "172.16.0.40";
@VSAT_ANCH_OID = ('1.3.6.1.4.1.2591.26.1.8.1.1.8.1.1', #CA Rx
'1.3.6.1.4.1.2591.26.1.8.1.1.8.3.1', #UN Rx
'1.3.6.1.4.1.2591.26.1.8.1.1.8.3.2', #GA Rx
'1.3.6.1.4.1.2591.26.1.8.1.1.8.3.4', #CB Rx
'1.3.6.1.4.1.2591.26.1.8.1.1.8.3.5', #SG Rx
'1.3.6.1.4.1.2591.26.1.8.1.1.8.4.1', #SP Rx
'1.3.6.1.4.1.2591.26.1.8.1.1.8.4.2', #KC Rx
'1.3.6.1.4.1.2591.26.1.8.1.1.8.4.3', #NO Rx
'1.3.6.1.4.1.2591.26.1.8.1.1.8.4.4', #FY Rx
'1.3.6.1.4.1.2591.26.1.8.1.1.8.4.5', #SA Rx
'1.3.6.1.4.1.2591.26.1.8.1.1.8.4.6', #AN Rx
'1.3.6.1.4.1.2591.26.1.8.1.1.8.4.7', #IL Rx
'1.3.6.1.4.1.2591.26.1.1.3.0'); #Tx Power Level
($session, $error) = Net::SNMP->session(
-hostname => $VSAT_ANCH_IP,
-version => $SNMP_VERSION,
-community => $SNMP_COMMUNITY,
);
$VSAT_ANCH = $session->get_request(-varbindlist => \...@vsat_anch_oid,
);
snmp_dispatcher();
$session->close();
-------------------------------------------------
Each of those OID values should return an integer value from 10000 to -2500.
I do not quite understand how to access the returned results in $VSAT_ANCH as
what I see in the variable is "HASH(0x9c75270)" when referenced.
Thanks for any help in pointing me in the right direction.
