Brad,
Thanks for your answer. On this email there are the first lines before to
start listening all metrics data. It says that the python module was loaded
but the I got an error message related to the metric tempHost.
Here is relevant information from my gmond.conf file:
module {
name = "python_module"
path = "modpython.so"
params = "/opt/ganglia/lib64/ganglia/python_modules"
}
include ('/opt/ganglia/etc/conf.d/*.pyconf')
Thoughts?
loaded module: core_metrics
loaded module: cpu_module
loaded module: disk_module
loaded module: load_module
loaded module: mem_module
loaded module: net_module
loaded module: proc_module
loaded module: sys_module
loaded module: python_module

Unable to find the metric information for 'tempHost'. Possible that the
module has not been loaded.
