Just to clarify this... you can certainly fix this by using
override_hostname however there is no reason why it shouldn't work without
it as long as the gmond that is being polled by the gmetad server can
reverse lookup the IP addresses of all other servers with gmonds.
Please check that reverse
Are you using override hostname or override IP? If so there was a
patch that fixed hostname corruption a few months ago which could be

Hi Adrian,
To create a grid of grids type hierarchy it depends on how the gmetad are
configured, not the gmonds. To get a gemtad to pull metric data from
another gmetad append the port number for the gmetad (normally 8651) to the
data source. Using your example the gmetad3.conf would look like
Yes, a gmetad or gmond can be polled by any number of different gmetad's in

Just to make it clear, you define statically
your descriptors in the metric_init function, and regularly, you check
for new metrics and call gmetric accordingly ?
No, using gmetric within a python module means you do not need to use
metric_init() to initialise any metrics at all.
However, we

We had a similar requirement for dynamically adding new metrics. The only
way we could make this work is to call gmetric from within the python
