Smarts ESM: How do you know if an F5 LoadBalancer is configured for virtual server discovery?



The Smarts Server Manager uses the following MIBs to determine if an F5 LoadBalancer is configured to be discovered with virtual server(s):

ltmVirtualServName ".1.3.6.1.4.1.3375.2.2.10.1.2.1.1"
ltmVirtualServAddr ".1.3.6.1.4.1.3375.2.2.10.1.2.1.3"
ltmVirtualServPort ".1.3.6.1.4.1.3375.2.2.10.1.2.1.6"
ltmVirtualServDefaultPool ".1.3.6.1.4.1.3375.2.2.10.1.2.1.19"
ltmVirtualServVlanVsName ".1.3.6.1.4.1.3375.2.2.10.9.2.1.1"
ltmVirtualServVlanVlanName ".1.3.6.1.4.1.3375.2.2.10.9.2.1.2"

You can use the following oid to determine how many virtual servers the LoadBalancer is configured with:

ltmVirtualServNumber ".1.3.6.1.4.1.3375.2.2.10.1.1"

For example,
ltmVirtualServNumber ".1.3.6.1.4.1.3375.2.2.10.1.1.0: 75"
ltmVirtualServName "1.3.6.1.4.1.3375.2.2.10.1.2.1.1.xx.xx.xx.xxx.xxx.xxx.xxx.xxx.xx.xxx.xxx.xx.xx.xx.xx: /Common/vs_<Virtual Server Name>
ltmVirtualServAddr "1.3.6.1.4.1.3375.2.2.10.1.2.1.1.xx.xx.xx.xxx.xxx.xxx.xxx.xxx.xx.xxx.xxx.xx.xx.xx.xx: <MAC Address>
ltmVirtualServPort  ""1.3.6.1.4.1.3375.2.2.10.1.2.1.6.xx.xx.xx.xxx.xxx.xxx.xxx.xxx.xx.xxx.xxx.xx.xx.xx.xx: 80
ltmVirtualServDefaultPool "1.3.6.1.4.1.3375.2.2.10.1.2.1.19.xx.xx.xx.xxx.xxx.xxx.xxx.xxx.xx.xxx.xxx.xx.xx.xx.xx: /Common/<Pool Name>_pool
ltmVirtualServVlanVsName "1.3.6.1.4.1.3375.2.2.10.9.2.1.1.xx.xx.xx.xxx.xxx.xxx.xxx.xxx.xx.xxx.xxx.xx.xx.xx.xx: <VlanVsName>
ltmVirtualServVlanVlanName "1.3.6.1.4.1.3375.2.2.10.9.2.1.2.xx.xx.xx.xxx.xxx.xxx.xxx.xxx.xx.xxx.xxx.xx.xx.xx.xx: <VlanVlanName>

The MAC Address and port number can change.  For each virtual server there will be a separate entry for the ltmVirtualServName, Addr, Port, DefaultPool.  It is not necessary to have Vlan info.
