The configuration file is not read by bash but it has a very powerful
feature : include
you can have a gmond.conf constructed with components like
include ("/path/setting1") ... include ("/path/setting2")
and each component you could customize with a script.
I think that it would be easier and flexible tot make a sed on a
component && gmond restart than to use something like env vars.
The plus side would be that each component could be remote customized
and deployed afterwards on the desired node.

[Ganglia-general] dynamic gmond parameters

2015-10-02 Thread Cristovao Cordeiro 
Hi,

is it possible to have gmond parameters that can get environment variables or 
simply return the value of a bash expression? Something like:
 ...
 override_hostname = "%{HOSTNAME}_myname"
 ...
(just an example)

Thanks

Cumprimentos / Best regards,
Cristóvão José Domingues Cordeiro

I'm also interested in this.
I was planing on ruining multiple mute=yes gmond instances on single
host via docker for aggregation purposes.
Having ability to read env variables would ease up deployment. For now
I was thinking about placeholders in conf files and some sed commands
before startup
