Pulseway is a relatively popular RMM solution that thankfully supports many Linux distros including SUSE up to SLES12, and even has a 2 device free account to let you test with. Unfortunately there are a few hurdles to get over currently with their 5.4 release in SLES15 thanks to Pulseway not currently supporting openssl 1.1 yet, or having a proper systemd start script and their systemV init script apparently having some strange init.d function requirement settings.
First we need to enable ssl 1.0.2 libraries from the Legacy release repository / Module. Note this will leave your openssl 1.1 intact.
Now that libssl1.0.2 is ready, we can install and the pulseway rpm
Note that the init.d script won't run as it is looking for various systemV functions under /etc/rc.d/init.d/functions that SLES15 doesn't have.
Instead, create a basic systemd script named pulsewayd.service under /usr/lib/systemd/system/ with the below, though do note this is a very basic systemd script that can simply handle starting and stopping the pulseway server. I may provide updates as I learn to tweak this further, or should someone else provide a more functional script.
*move the pre-existing /etc/init.d/pulseway script into another directory so you don't accidentaly try running it and get confused when it complains about functions missing.
