Xymon on the Cloud

Morning or Evening, Everyone. I am looking at deploying Xymon, through the Google Cloud Compute service, I sadly have no space for a physical server and was wondering if can Zymon can run on an low amount of ram and CPU.

Define low. How many servers? Xymon is very low memory/CPU demanding for sure. Josh Luthman Office: XXX-XXX-XXXX Direct: XXX-XXX-XXXX XXXX Wayne St Suite XXXX Troy, OH XXXXX On Mon, Mar 25, 2019, 6:16 PM Matthew Gregory <user-ffa8a7401790@xymon.invalid>

Hi Matthew, I've run Xymon very successfully in AWS on a T1 instance (1 vCPU and 1 GB RAM). I've also run it very successfully on a Raspberry Pi John Alexander

Sorry. That would be a T2.micro instance. John Alexander

I am currently running my server on a IBM xSeries 336 (dual 2.6 GHz Pentium 4, 2 GB ram). Below are teh details from the xymonnet page that show hosts, tests, ... This basically says all tests done by server are completed within 43 seconds (26 of that is DNS). xymond report tells me I average 6 incoming status messages a second from the clients. Load average for this server stays below 0.3 (last 2 days). For last two days, it totals 94% idle. In other words, the server does not need much memory or cpu -- especially if you distribute the tests to clients. Xymon supports central testing as well as distributed testing. I tend to distribute as much of the testing as I can/as makes sense (the client runs the test and merely reports status to server). Feel free to contact me directly if you would like more info or details.

Hello Isaac, Pentium 4 wow, I shouldn’t have any problems then, what version of Linux runs in the background?

It really depends upon what you're doing with it. (How many servers, how many tests, and how much of that is server-side). Even when monitoring non-trivial networks, the amount of CPU and memory needed tends to be rather low. I've monitored networks of 2000 boxes on a server with a pair of dual-core, 1.6 GHz Xeon's. What you do need, when you scale up to those numbers, is a non-trivial amount of disk-I/O. Keeping 10,000+ RRD files updated takes some bandwidth. On the other hand, if you're only monitoring a dozen servers, you can run the xymon server on most anything you have available. -- Michael T Pins | "There was a point in time when the user-207e48c0954b@xymon.invalid | Macintosh crashed an awful lot more keeper of the nn sources | than Windows machines" ftp://ftp.nndev.org/pub | - Steve Wozniak

In past we had xymon running on VMware with 4vcpu/4GB memory and we were monitoring close to ~500 servers, now you can judge it. Sent from my iPhone

We have about 80 servers monitored by xymon and over 500 fake hosts (we have hostnames that specify some specific scripts that monitor our service). The LA is near 0, about 3gb of ram used and 15 messages/sec on average. I've had a previous installation of xymon monitoring about 2000 servers and we never ran into scalability issues and I think the machine had 4 cores / 8gb of ram on dedicated hardware.
