Which easy / simple server monitoring tools / services exist ?
So, I’ve set up my droplet (lemp) and configured it completely. DigitalOcean offers unmanaged services, which means I would like to ad a server monitoring tool / service.
I was wondering if someone could recommend some good monitoring tools / services … Even external paid services are an option for me … as long as adding it and working with it is quick and easy …
Another question I have : ofcourse these tools / services have to collect data from the server .... does this have an effect on the speed of operation of the server ? (as in : making it a little slower overall ?) …
