I would like to know if it is possible to use NUT to monitor more than one
UPS and shutdown the computer only when the battery of the last alive UPS
gets low?

I have a file server that relies on two other LDAP servers (each with its
UPS) and I would like to shutdown the file server when its UPS battery gets
low or when the battery of the other two UPS (LDAP servers) gets low too.


1 - If UPS01 battery low, shutdown LDAP1 and keep LDAP2 and NFS alive.
2 - If UPS02 battery low, shutdown LDAP2 and keep LDAP1 and NFS alive.
3 - If UPS03 battery low, shutdown NFS.
4 - If UPS01 (and LDAP1) down and UPS02 battery low, shutdown NFS and LDAP2
(in this sequence).
5 - If UPS02 (and LDAP2) down and UPS01 battery low, shutdown NFS and LDAP1
(in this sequence).

Thanks and best regards.
