Hello,
I am having similar issues.
A gmetad is running on another host, monitoring a cluster. Its grid name
is "GangliaGrid". I created a gmetad.conf on my laptop, with a tunnel to
the remote host, forwarding its XML port (8652) to the localhost:8666.
Telnet to localhost 8666 shows that the remote gmetad answers fine to
queries like "/"...
The local gmetad (on the laptop) uses in its conf:
debug_level 1
setuid off
gridname "LocalGrid"
data_source "GangliaGrid" localhost:8666
trusted_hosts 127.0.0.1
xml_port 18651
interactive_port 18652
rrd_rootdir rrds
Unfortunately I see only timeouts.
Sources are ...
Source: [GangliaGrid, step 15] has 1 sources
127.0.0.1
Data thread 140659923203840 is monitoring [GangliaGrid] data source
127.0.0.1
poll() timeout from source 0 for [GangliaGrid] data source after 0 bytes
read
If I use the same ganglia grid name in both gmetad's, gmetad dies
immediately.
Any idea what's going on?
Best regards,
Erich
