SNMP and syslog forwarders

Hi, It's looking like running all of our traps and syslog through a couple of relay devices (and then onwards to the various NMS's) would be quite a win for us. These relay devices just need to be "dumb" forwarders (we don't require any filtering or storing, just reflection), but we need an HA pair (across two sites) without creating duplicates. I have the coding skills to make this myself, but as coding skills come and go in our network team, we are looking for a commerical product so it will continnue to work after I get: hit by a bus / amnesia / visions of grandeur. Any recommendations / experience? This needs to scale to ~1,500 devices. Thanks, Sam
