Re:Pulse - e-mail notification and external script?

I could be wrong, but lvs doesn't implement failover notifications.

Using self-made scripts, you can check ipvsadm output; on the primary, yo=
u see (for example):

# ipvsadm
IP Virtual Server version 1.2.1 (size=3D4096)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
TCP  lbwww:http rr
  -> <real_node01>:http               Route   1      0          0        =
=20
  -> <real_node01>:http               Route   1      0          0        =
=20

On the slave director, instead:

# ipvsadm
IP Virtual Server version 1.2.1 (size=3D4096)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn

You can build a monitoring script which checks the output and sends a mes=
sage.

Good work,
