Hy to all,

Thanks in advance, bye.

Hey Matteo
In order to monitor the interfaces you can use either the MIB files which you can download from the BIG-IPs WebGUI or use the OIDs. You should be able to define that in the monitoring software.
K13322: Overview of BIG-IP MIB files (BIG-IP 10.x - 13.x)
To use the OIDs please use the following:
- sys interface stat name - 1.3.6.1.4.1.3375.2.1.2.4.4.3.1.1
- sys interface stat pkts in - 1.3.6.1.4.1.3375.2.1.2.4.4.3.1.2
- sys interface stat pkts out - 1.3.6.1.4.1.3375.2.1.2.4.4.3.1.4
- sys interface stat bytes in - 1.3.6.1.4.1.3375.2.1.2.4.4.3.1.3
- sys interface stat bytes out - 1.3.6.1.4.1.3375.2.1.2.4.4.3.1.5
- sys interface stat errors in - 1.3.6.1.4.1.3375.2.1.2.4.4.3.1.8
- sys interface stat errors out - 1.3.6.1.4.1.3375.2.1.2.4.4.3.1.9
- sys interface stat drops in - 1.3.6.1.4.1.3375.2.1.2.4.4.3.1.10
- sys interface stat drops out - 1.3.6.1.4.1.3375.2.1.2.4.4.3.1.11
- sys interface status - 1.3.6.1.4.1.3375.2.1.2.4.1.2.1.17
These are just some of all the different OIDs you can use. You can also run an SNMP walk on the BIG-IP to see which information you want to monitor:
sys interface status
[root@bigipcore02:Active:Changes Pending] config snmpwalk -v2c -c public localhost 1.3.6.1.4.1.3375.2.1.2.4.1.2.1.17 F5-BIGIP-SYSTEM-MIB::sysInterfaceStatus."1.1" = INTEGER: up(0) F5-BIGIP-SYSTEM-MIB::sysInterfaceStatus."1.2" = INTEGER: up(0) F5-BIGIP-SYSTEM-MIB::sysInterfaceStatus."1.3" = INTEGER: up(0) F5-BIGIP-SYSTEM-MIB::sysInterfaceStatus."1.4" = INTEGER: up(0) F5-BIGIP-SYSTEM-MIB::sysInterfaceStatus."1.5" = INTEGER: up(0) F5-BIGIP-SYSTEM-MIB::sysInterfaceStatus."mgmt" = INTEGER: up(0)
sys interface stat bytes in
[root@bigipcore02:Active:Changes Pending] config snmpwalk -v2c -c public localhost 1.3.6.1.4.1.3375.2.1.2.4.4.3.1.3 F5-BIGIP-SYSTEM-MIB::sysInterfaceStatBytesIn."1.1" = Counter64: 431764883 F5-BIGIP-SYSTEM-MIB::sysInterfaceStatBytesIn."1.2" = Counter64: 601533207 F5-BIGIP-SYSTEM-MIB::sysInterfaceStatBytesIn."1.3" = Counter64: 120 F5-BIGIP-SYSTEM-MIB::sysInterfaceStatBytesIn."1.4" = Counter64: 339808188 F5-BIGIP-SYSTEM-MIB::sysInterfaceStatBytesIn."1.5" = Counter64: 391200 F5-BIGIP-SYSTEM-MIB::sysInterfaceStatBytesIn."mgmt" = Counter64: 256710269
That is just interface information and statistics. Since interfaces are assigned to one or more VLANs, it could be more interesting to see the statistics and status of a particular VLAN. In those cases you can use the following OIDs:
- sys vlan stat vlan name - 1.3.6.1.4.1.3375.2.1.2.13.6.2.1.1
- sys vlan stat pkts in - 1.3.6.1.4.1.3375.2.1.2.13.6.2.1.2
- sys vlan stat pkts out - 1.3.6.1.4.1.3375.2.1.2.13.6.2.1.4
- sys vlan stat bytes in - 1.3.6.1.4.1.3375.2.1.2.13.6.2.1.3
- sys vlan stat bytes out - 1.3.6.1.4.1.3375.2.1.2.13.6.2.1.5
- sys vlan stat errors in - 1.3.6.1.4.1.3375.2.1.2.13.6.2.1.8
- sys vlan stat errors out - 1.3.6.1.4.1.3375.2.1.2.13.6.2.1.9
For example:
sys vlan stat vlan name
[root@bigipcore02:Active:Changes Pending] config snmpwalk -v2c -c public localhost 1.3.6.1.4.1.3375.2.1.2.13.6.2.1.1 F5-BIGIP-SYSTEM-MIB::sysVlanStatVlanName."/Common/HA" = STRING: /Common/HA F5-BIGIP-SYSTEM-MIB::sysVlanStatVlanName."/Common/dmz" = STRING: /Common/dmz F5-BIGIP-SYSTEM-MIB::sysVlanStatVlanName."/Common/lan" = STRING: /Common/lan F5-BIGIP-SYSTEM-MIB::sysVlanStatVlanName."/Common/server" = STRING: /Common/server F5-BIGIP-SYSTEM-MIB::sysVlanStatVlanName."/Common/FW_F5_Linknet" = STRING: /Common/FW_F5_Linknet
sys vlan stat bytes in
[root@bigipcore02:Active:Changes Pending] config snmpwalk -v2c -c public localhost 1.3.6.1.4.1.3375.2.1.2.13.6.2.1.3 F5-BIGIP-SYSTEM-MIB::sysVlanStatBytesIn."/Common/HA" = Counter64: 120 F5-BIGIP-SYSTEM-MIB::sysVlanStatBytesIn."/Common/dmz" = Counter64: 393720 F5-BIGIP-SYSTEM-MIB::sysVlanStatBytesIn."/Common/lan" = Counter64: 340095317 F5-BIGIP-SYSTEM-MIB::sysVlanStatBytesIn."/Common/server" = Counter64: 601817438 F5-BIGIP-SYSTEM-MIB::sysVlanStatBytesIn."/Common/FW_F5_Linknet" = Counter64: 433053417 [root@bigipcore02:Active:Changes Pending] config
I hope this helps!
