If you only want to disable flows coming in that match a particular in and out interface combination, then you should set that specific record inactive and leave the wildcard record active.
License Count
Our development team has provided the following query that will produce the nodes/interfaces that are being used to calculate interface usage.
| Code Block |
|---|
mongo -u opUserRW -p op42flow42 --host 127.0.0.1 flows --eval 'db.getCollection("agents").aggregate([ { "$match" : {"in_if" : { "$ne" : "*" },"out_if" : { "$ne" : "*" }, "admin_status" : "active" }},{ "$group" : {_id : "$agent","in_if" : { "$addToSet" : "$in_if" },"out_if" : { "$addToSet" : "$out_if"}}}, { "$project" : { _id : 1,interfaces : { "$setUnion" : [ "$in_if","$out_if" ] }}} ]);' |
This command may be used from the command line. From our test machine it results in the following:

[root@opmantek bin]# mongo -u opUserRW -p op42flow42 --host 127.0.0.1 flows --eval 'db.getCollection("agents").aggregate([ { "$match" : {"in_if" : { "$ne" : "*" },"out_if" : { "$ne" : "*" }, "admin_status" : "active" }},{ "$group" : {_id : "$agent","in_if" : { "$addToSet" : "$in_if" },"out_if" : { "$addToSet" : "$out_if"}}}, { "$project" : { _id : 1,interfaces : { "$setUnion" : [ "$in_if","$out_if" ] }}} ]);'
MongoDB shell version: 3.2.16
connecting to: 127.0.0.1:27017/flows
{ "_id" : "10.8.0.1", "interfaces" : [ 0 ] }
{ "_id" : "192.168.10.71", "interfaces" : [ 3, 10, 9, 2, 8, 5, 6 ] }
{ "_id" : "10.10.1.1", "interfaces" : [ 5, 4, 0, 1, 2, 3 ] } |
The _id value is the source IP address of the sFlow sample, This can be considered the Node. The numbers in the interfaces field are the SNMP indexes of the subject interfaces.
Note: Disabling all flows in+out of an interface will remove it from the licensing count (lowering the used count by one interface). opFlow 3.0.2 requires each combo to be disabled, just disabling the wildcard record will not remove the interfaces from the licensing count. The GUI refreshes the license count every 5 minutes, restart omkd if you would like to see the most up-to-date count immediately.
