Hello, i would like to setup a mass test environment for 250+ students for example a setup with two clusters that we manage: cluster PUB and cluster SUB goal: on cluster PUB each student has its own database mirrored/replicated to his own database at cluster SUB starting point: * the databases on cluster PUB already exist with content * the empty databases on cluster SUB already exist (without any content) * no publication (and thus subscription is already running) so the exercise for each student would be: 1. create publication 2. mirror the structure (backup/restore) 3. create subscription 4. test replication (with dml: insert/..) So what would be your suggestion to setup an easy monitoring setup to check that the student succeeded in this exercise background: vanilla debian with postgres apt repository, preferable with software from these repositories for security and maintenance reasons (at the moment i check with some handmade scripts that query the cluster and the logs) mvg, Wim
