I'm not sure what value you're refering to, not big on ASDM here.
But I would check:
show snmp-server oidlist
And if you're interested in something you can check what it stands for as usual:
Potentially you could be interested in:
 184.108.40.206.220.127.116.11.1.14. ifInErrors
 18.104.22.168.22.214.171.124.1.20. ifOutErrors
But that's just interface level.
If I'm correct about my feeling - this particular counter comes from threat detection feature (which is AFAIR not yet monitored by SNMP)
