Hello,

I'm wondering what people are using to monitor Slony with Nagios. The
docs reference:

psql_replication_check.pl

... but that uses the very ancient "Pg.pm" and not DBI/DBD::Pg.

I also see "test_slony_state-dbi.pl", which uses DBI, but is not
referenced as a Nagios plugin.

I'm also curious if anyone is using Nagios' event handling as part of
failover-- using it to notice that a slave is down, and then make a
pro-active change to handle failover.

I'm evaluating various options to handle failover. DBIx::HA seems like
area reasonable solution for Perl, but I'm still exploring other options
at this point.
