      @scottalanmiller Any tips on how to tune a Linux machine?
      I'll be running
      Unifi Controller V4
      Zabbix (Latest Version)
      Snipe-IT - once they develop the fixed asset number thingy

      Easy way is to start with the recommended minimums and monitor over time. Watch the systems to see what the memory is doing and tune up or down as needed. We have a good idea about certain workloads that we deploy regularly so can set good starting points very easily. But for new workloads, you can put in a reasonable guess and then tune.

        What's the best method to "monitor" the resources in Linux?

          What hypervisor are you using? That will generally tell you when you are maxing out in memory. If not check out:

          top
          

          to see what resources your app is using.

            Exactly what @coliver said. Htop and glances are also other popular ones.

              I forgot about Glances. I need to set that one back up again.

                Yep either of those work too. top is generally installed by default on most *nix systems though so you wouldn't have to install anything new.

                    Really? I'm not sure you can get performance information from that host then. I've never seen anyone use the ESXi Free version so I don't know how it interacts with that kind of data.

                      For a glance, the free command tells you all that you need to know. To see over time, sar does. To watching it for a while, top or vmstat.

                        I'd start by replacing that 😉

                            You don't have to... but that is going to be a limiting factor in a number of ways. Especially when you are looking at management or want to expand your infrastructure.

                              How are you backing up those servers right now? You can't use most of the free tools because you can't access the backup API in ESXi Free.

                              Converting to Hyper-V is completely free from a software perspective and gives you so many more options.

                                Have you used the alternatives? Some of them are seriously smooth.
