Hello,
I have reinstalled Ganglia 3.1.1. After configured gmond.conf and
gmetad.conf at my local machine(actually I just use one machine to run
Ganglia, user is root), I started gmetad with debug level 1 it shows
following messages:
Sources are ...
Source: [A, step 15] has 1 sources
127.0.0.1
Data thread 90573744 is monitoring [A] data source
127.0.0.1
data_thread() got no answer from any [A] datasource
And when I started gmond it shows following error messages:
Error creating multicast server mcast_join=127.0.0.1 port=8649
mcast_if=NULL family='inet4'. Exiting.
I could use telnet to access port 8651 at localhost but not 8649. I feel
very confused about that because I don't know why this problem happened.
The attachment I provide are my configuration files, because I'm a
newbie at this so please tell me more details or fixes for my files.
Huge thanks to you.
Amy
