Xymon on the Cloud

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.

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.

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.
