Well you did make me think...and that on a Sunday evening ...
My thoughts:
"
SA can operate in 3 modes:
* normal (as it is now)
* master
* slave
on the SA_master you define who are the slaves. For each entry you can
define who are the entries on the slave(s) that are linked.
(master_UID_7 has a slave slave_01_UID_45 and slave_02_UID_56)
When SA_master checks UID_7 it will after the check query sa_slave_01 to
get the status of uid_45 and it will also query sa_slave_02 to get the
status of uid_56. The query will be done via an SSH like connection that
will be kept open during the "running" of sa_master (ofcourse if the
connection is dropped for whatever reason, we will remake the connection).
on the master you define within the alerts that ALL slaves must be down too
OR "at least y slaves must be down too" and this in combination with the
normal alerting rules based on the status on the sa_master.
on the add/edit entry screen on sa_master you will be able to select the
corresponding slave entries via a list/dropdown/... (list will be read at
startup of the master, with an update button on the GUI -> in order no to
have too much network traffic).
on the sa_slave stations you can define what sa_masters are allowed to
connect, and the connection will need authentication (like the "normal"
connection to the ssh server of SA).
"
Those are my thoughts on the "issue".
Timeframe for implementation? Unknown :-) Not directly, too busy with
other things (like moving to a new house and to a new office).
dirk.

Oh, I know, I know. I was simply wondering whether anyone had set up
a multiple SA checker system, where part of the checks involved checking
the web pages produced by the other SA monitoring points. Sounds to me
like it COULD be done - I was just wondering if anyone was actually
doing it.
