What does this error mean, how can I fix this
When I start gmetad with debug level 10,
I guess this should create "SQL Cluster" directory in
/var/lib/ganglia/rrds/
Thank you,

gmond is running on all the nodes adn gmetad is running on web1 (master
for ganglia).
Now the problem is that all the nodes are displayed in the same
cluster.
data_source "WEB SERVER" web1:864 Web2:8649 web3:8649 web3:8649
data_source "SQL Cluster" SQL1:8649 SQL2:8649 SQL3:8649
From these statements I was expecting that web1, web2, adn web3 will
be in WEB SERVER cluster and SQL1, SQL2 and SQL3 will be in SQL
Cluster.
My SQL Cluster is empty.
Can some one give me hint what I am missing.
Thank you,

Jai,
Try creating a second gmond.conf for the SQL Cluster. Set the udp_send
host to sql1 instead of web1. sql1 will be your headnode for the SQL
cluster. Then restart all the gmonds and gmetad.
You don't need to define all the nodes on all the clusters in the
gmetad.conf, just the headnodes. The list is for failover, if the first
headnode fails to respond, the second will be queried. In your current
setup, you only have one headnode, web1.
Good Luck,
Ian
