Hi all,
We are attempting to setup Xymon at our organization, where it
would be monitoring approximately 20,000 hosts with the Xymon
client in central mode (pulldata). Just wondering if anyone has
Xymon monitoring anywhere close to that number of machines? We are
looking for ideas on what hardware specs would be required for the
machine running the server side of the Xymon software, or other
suggestions on how to setup the environment. Is there a way to
load balance multiple Xymon servers?
I wasn't auite up to that number of hosts when I had a large
installation - only about 7000 hosts. But I expect that Your main
bottlenecks will be
a) Disk I/O for the RRD files. Use SSD disks for those.
b) TCP sockets. All of your client messages end up being converted
into status-messages, and sent back to xymond via a normal TCP
connection, so you will be using lots of sockets on the Xymon server.
Enabling the "backfeed" feature will fix that for you.
As for hardware specs, I think any "decent" server will work fine.
Dual- or quad-core, and for memory a rough estimate is ~200 kB per
host you monitor. So 4 GB for Xymon, and hence a 64-bit system.
I am curious to hear how it works out for you.
Regards,
Henrik
