Two classes of collection are considered to count towards an ‘instance’
for licensing purposes.
1)
I/O Collections.
I/O collections involve
ifInOctets, ifOutOctets, ifInErrors, ifOutErrors, CiscoAvgBusy5 and sysuptime
are in the I/O class.
2)
Non- I/O Collections.
All other collections are
considered as user defined collections.
If no collections exist then otadd will
setup collections based purely on I/O OR if there is a definition for the SNMP
sysObjectID in the templates.xml file then that will be used.
For I/O collections (from routers and switches or other network
interfaces)
1 instance = 1 interface's InOctets, OutOctets, InErrors and OutErrors.
1 instance = Cisco CPU Average Busy 5
For all other collections 1 instance = 1 SNMP instance
So collection 1 router’s 10 interface’s In and Out octets is 10
instances.
Collecting In and Out octets from 5 routers each with router having 2 interfaces
is also 10 instances.
Collecting a single OID instance (non I/O) from 7 switches is 7
instances.
