I am trying to polling interface traffic with customized oids, here index is not standard, I am getting query_index values by quering objectName, its giving me interface names, interface names are converted to query_index value however showing U result
command line snmpget for concatenating OID is working
example:-
root@tejagponnms:/var/www/html/cacti/scripts# php -q olt_interface_traffic.php xxx_WTT_xxx_SME xxxx 1 161 500 "" "" "" "" "" "" "" get tejasStoctetsRx 2
.1.3.6.1.4.1.8255.1.2.1.2.37.1.1.480.10000.1.1.2 ---> this is concetinated OID
U --> result
command line output
root@tejagponnms:/var/www/html/cacti/scripts# snmpget -v2c -c xxxx xxx_WTT_xxx_SME.1.3.6.1.4.1.8255.1.2.1.2.37.1.1.480.10000.1.1.2
