One more. In thinking about the system design, why do you not put the onus of processing on each remote?

The remote has crontab script to run stuff at 2:00AM or whatever. Then it sends a communication via scp-ed file to your local system, 'come get your files and it ran 03:14:10 duration today' or ' I have a problem'. Whatever you need to see

Your local code just checks once a minute to see who has sent files. At the end of the run, checks that a required number of communication files exists or from required servers.

Do not forget to include the monitoring nagios box (or whatever) as part of the problem set. It could have problems, too.

Why would you do this? It is kind of like instrumenting a code base deployed all over the place, what you need to start finding problems. We use a database to keep this stuff. Oracle in our case. SQL is an extremely efficient and powerful tool for scanning datasets for almost anything. Oracle dumps a daily control file for our local monitoring script, because we have a lot of 'If today is Tuesday and I like bacon then do this' kinds of ill-conceived business rules about monitoring stuff.

SYSTEMD-RC-LOCAL-GENERATOR(8)                               systemd-rc-local-generator                               SYSTEMD-RC-LOCAL-GENERATOR(8)

NAME

       systemd-rc-local-generator - Compatibility generator for starting /etc/rc.local and /usr/sbin/halt.local during boot and shutdown

SYNOPSIS

       /lib/systemd/system-generators/systemd-rc-local-generator

DESCRIPTION

       systemd-rc-local-generator is a generator that checks whether /etc/rc.local exists and is executable, and if it is pulls the
       rc-local.service unit into the boot process. This unit is responsible for running this script during late boot. Note that the script will
       be run with slightly different semantics than the original System V version, which was run "last" in the boot process, which is a concept
       that does not translate to systemd. The script is run after network.target, but in parallel with most other regular system services.

       systemd-rc-local-generator also checks whether /usr/sbin/halt.local exists and is executable, and if it is pulls the halt-local.service
       unit into the shutdown process. This unit is responsible for running this script during later shutdown.

       Support for both /etc/rc.local and /usr/sbin/halt.local is provided for compatibility with specific System V systems only. However, it is
       strongly recommended to avoid making use of these scripts today, and instead provide proper unit files with appropriate dependencies for
       any scripts to run during the boot or shutdown processes.

       systemd-rc-local-generator implements systemd.generator(7).
