Hi,
Not sure if you ever solved your problem but I think you are missing
the following config stanza from gmond.conf for the gmond that is
receiving the sFlow packets.
sflow {
accept_vm_metrics = yes
}
I'm just trying this out myself for the first time and see the VM
metrics appear when gmond is run in debug mode but there is no trace
of them in the XML output.
$ gmond -d 2
...
saving metadata for metric: infsrcprv10.vdisk_capacity host: smc02
***Allocating value packet for host--(null)-- and metric
--infsrcprv10.vdisk_capacity-- ****
...
I would guess that something is going wrong when decoding the sFlow
packets because a host of "(null)" can't possibly work.
Has anyone else go this working?
Regards,
Nick
PS. I'm running ganglia agent version 3.5.0 and host sFlow agent version 1.22.2.
