munin 대신 ganglia를 검토해보려고 ganglia를 설치하려는데 아래 메시지를 내뿜으며 설치가 제대로 안된다.

Adding group: ganglia.
Adding system user: ganglia.
useradd: group ganglia exists - if you want to add this user to that group, use -g.
dpkg: error processing gmetad (--configure):
 subprocess installed post-installation script returned error exit status 9
Processing triggers for libc-bin ...
ldconfig deferred processing now taking place
Errors were encountered while processing:
 gmetad
E: Sub-process /usr/bin/dpkg returned an error code (1)`

sudo useradd ganglia -g ganglia

음.. 우분투 실망일세~~
