please check your udp_send_channel entries and make sure that gmond is really sending on the channels you have specified. also, make sure that the gmond you are querying for XML data is even setup to receive data from the udp channels (otherwise it will not even process data to memory). if you are using multicast (the default configuration) make sure that multicast is enabled on your network and that gmond is receiving the messages.

good luck.. we'll track down the problem.

Hi, all: I've come across a problem with gmond that has me perplexed. I've got a FreeBSD 5.3 machine that I'd like to monitor with gmond; using both the FreeBSD ports build (3.0.0) and a build from the 3.0.1 tarball, no metrics appear in the Ganglia XML output on port 8649. I've tried using both a converted gmond.conf from 2.5 and using the default gmond.conf for 3.0, to no avail; there's also nothing obviously wrong in the debugging output.

While the XML is properly formed, there's no HOST stanza within the CLUSTER:

| <?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?>
| <!DOCTYPE GANGLIA_XML [
| ...
| <GANGLIA_XML VERSION="3.0.1" SOURCE="gmond">
| <CLUSTER NAME="unspecified" LOCALTIME="1113037978" OWNER="unspecified" | LATLONG="unspecified" URL="unspecified">
| </CLUSTER>
| </GANGLIA_XML>

This problem seems to have cropped up on ganglia-general once before (late April '04), but there doesn't seem to have been any on-list answer. Does anyone have any insight into what might be causing this, or how to track it down?

Cheers,

Chris
