Hello,
to follow up on this: I reinstalled ganglia version 3.1.7 (was using
3.1.2 before). It seems to work a lot better now, I get regular updates
of all the nodes etc. Still, gmond or gmetad crash after a while - I am
logging in debug mode now to see what's happening.
After I reinstalled ganglia 3.1.7 I am getting an error message upon
starting gmond. When loading the custom SGE metric module, I get:
$ gmond -d 10
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
[PYTHON] Can't import the metric module [sge].

Unable to find the metric information for 'queue-state'. Possible that
the module has not been loaded.
Any idea where this might come from? Did any interfaces change between
3.1.2 and 3.1.7? Do I need to ajust the SGE module somewhere?
Cheers,
Arne
