Hi Kris,

There's more to it than that. You need something to run it regularly and you need some way of getting the output back to your server.

The stock standard way is like any other unix/linux system. You have a program called xymonlaunch running full time on the system. At regular (5 minute) intervals and under control of clientlaunch.cfg, it loads up the environment from the config file (xymonclient.cfg) and kicks in the xymonclient.sh script into action. This script does various pieces of housekeeping and runs the architecture dependant script (in your case xymonclient-darwin.sh). It then runs the binary file xymon to send the results back to your server.

As Ralph has pointed out, you can avoid running xymonlaunch and schedule the process using cron or whatever apple uses for running jobs these days. These is no systemd or init.d processing on a Mac. It's much uglier ?.

The other approach is to use the rclient script.

Assuming you have ssh access to the Mac, you set up a certificate based ssh login on the Mac. On your server you then schedule regular running of the rclient script. This works through each required system and runs the script as a sequence of commands over ssh, capturing the output and handing it back to the main xymon processes. The advantage of this is that your don't need any binaries on the target system, just an ssh login. Setting up rclient and ssh keys could be a little daunting if you're not familiar with that sort of thing.

If you have a Mac laptop with Apple's developer tools installed, you could build your own binaries. Download the whole xymon source archive, unpack it and run 'configure --client'. Follow the prompts to install the result in an out of the way place (I use /usr/local/xymon). When built, copy that whole directory over to your target machine. Apple have recently changed processors from intel to arm so you need to make sure you are building compatible binaries. This approach is going to be much safer than trusting some random person on the internet to give you pre-compiled binaries to run.

Alternatively, installing via homebrew would be relatively painless and a little more trustworthy. It's actually quite simple and well designed.

Hope some of this helps,

Brian

So I copied xymonclient-darwin.sh onto a Mac laptop I have and just ran it from a terminal to see if it would do anything.? It did display a lot of great info in the terminal, but there's nothing in the script that dumps the output to a tmp file or points to a Server address.? So I pulled a few more files from the Sourceforge /client/ folder in the hopes that the script would look for the xymonclient.cfg and send some data to the server. Running the xymonclient.sh script tries to do somethings, but it's looking for things in paths that don't exist since I'm not actually installing anything, I'm just manually running a script. I'm obviously missing some vital piece of this puzzle.? Does anyone have some simple instructions or point me at whatever it is I'm missing here?? I find it hard to believe there isn't someone out there that's got this figured out already.

Thank You,

As far as autostart goes, I have a bunch of clients running from cron.? Forget runclient.sh, just start the main xymonclient.sh every five minutes.? That is, you don't need to fight with systemd or init.d to get the client?to report.

    A few years ago I built a client for a Macos server. The target
    server is quite a few versions of macos old so probably not what
    you are looking for. I just built it on my Mac laptop then
    bundled it all up in a tar file and copied it over and did some
    installation. My current laptop is an M2 so I doubt I could do it
    again right now.

    As I recall the xymonclient-darwin script was mostly fine. There
    was a little entertainment with the way Apple manages it's disks
    these days. I've attached what looks like the changes I made as a
    diff.

    I'm not at $work at the moment so I can't check exactly what else
    I did. I must have done something to get it to auto start at
    boot. Probably didn't keep any notes either. I'll try to have a
    look next time I'm there.

    Also quite possible that rclient will work well. There's some
    fixes that I had to do recently to account for some dropped
    commands from rclient when talking to FreeBSD systems so that may
    also be relevant.

    Cheers,

    Brian

    I would guess the script in the repository is the latest
    version.? I'm not a Mac user, so take that as an opinion, not a
    fact.? As part of the main distribution, any changes would have
    been rolled into that file.

        Where would I obtain a semi-current xymonclient-darwin.sh
        script?? I will try to use the one I found in the latest
        branch on Sourceforge that JC has been working on, but it
        was last edited in 2015.
        https://sourceforge.net/p/xymon/code/HEAD/tree/branches/4.x-master/client/xymonclient-darwin.sh

        Does anyone have anything a little more current that they use?

        Nothing to install on the remote host, other than SSH
        keys.? It fires the appropriate xymonclient-[OS].sh script
        down the SSH connection and collects the results.? I don't
        know anything about Macs, but the xymonclient-darwin.sh
        script is for MacOS X so that might be a good starting point.

            Anyone have a modern xymon-client script or app that
            will run on Mac? I'm aware of the macport method, but
            that's a large footprint and heavy handed solution to
            the simple need of collecting performance data and
            uploading it to the Server.
