apt install sysstat

Install pgcluu from repos: XXX don't do this way

apt install pgcluu

Meh, the packaged version is ancient, use latest release

apt remove pgcluu

Manual install instead:

sudo apt install make wget -O pgcluu-2.7.tar.gz https://github.com/darold/pgcluu/archive/v2.7.tar.gz tar zxf pgcluu-2.7.tar.gz cd pgcluu-2.7/ perl Makefile.PL make sudo make install sudo mkdir -p /var/lib/pgcluu/data/pg1 /var/lib/pgcluu/data/pg2 /var/lib/pgcluu/data/pg3 /var/lib/pgcluu/data/pg4 sudo chown -R pgcluu:pgcluu /var/lib/pgcluu sudo mkdir /var/run/pgcluu sudo chown pgcluu:pgcluu /var/run/pgcluu

Set up script for user pgcluu to run:
