Subject: Ganglia unable to report remote client
My ganglia setup is able to report only one guest which is local server on
which gmond and gmetad both are installed . It does not show up other
clients inspite of proper configurations with gmond .
Remote gmond process is running absolutely fine .
Debugging done so far
1) I also verified that port 8649 are free and not used using lsof -i
tcp:8649
2) /var/log/messages do not show any error
3) all the processes - gmetad , gmond are running fine
Please suggest steps/tips to debug the issue further .
Server config
gmetad.conf :
data_source "hadoopgpfs" bigdatagpfs01
gridname "MyHadoopGPFSGrid"
setuid_username "root"
case_sensitive_hostnames 0
gmond.conf :
/* This configuration is as close to 2.5.x default behavior as possible
The values closely match ./gmond/metric.h definitions in 2.5.x */

# By default gmond will use reverse DNS resolution when displaying your
hostname
