Just curious to see how many NSCA transactions people are running in their environments. I am trying to send 3000 service check results every 5 minutes from one machine to another. I am using xinetd which seems to panic at this volume and shut itself down. At 2200 service checks i did not have issues with xinetd. I have also been trying to convince my coworker that we should be doing all of the checks from one server so this would not be an issue. And the second server can be the redundant fail over. My server is 2 x dual core 2.0 Ghz, 8 GB of RAM and 6 300GB 15k disks in raid 5 with a single 1Gb network connection. My current load on this machine with 3000 + service checks in 5 minutes is around 10% cpu usage. About 2% of that is nagios related. The total need for service checks will be about 12.5k every 5 minutes, we are implementing in phases. I think I can do this all from one machine and replicate everything to my fail over server for redundancy. How many service checks are people doing in their environments and then submiting with nsca and how many checks are people doing from one server?
