I am testing ceilometer in my devstack virtual machine. Although I
can see the meter data model in the mongodb, I am confused about
some glossary when I test its Web API. I am not very clear about the
" resource" in the " GET /v1/resources",either "source" in the "GET
/v1/sources/(source)/meters/(meter)".
Can someone explain these two concept? Thanks a lot.
Hi Yawei,
Good question!
My understanding is that the resources collection refers to the set
of UUIDs identifying the openstack entities (e.g. instance, volume,
image ... etc.) being metered, whereas the source refers to the
origin of the metering data and is effectively unused right now
as there is only a single source currently (though we could in the
future for example distinguish between metric and metering data
in this way).
Cheers,
Eoghan
Thanks Eoghan,
I still have questions about the data in the mongodb.
First: All the data about "source" in db is "?",for example:
-
"source": "?",
"metadata": {
"fixed_ip_id": null,
"host": null,
"auto_assigned": false,
"pool": "nova",
"address": "172.24.4.232"
}
is it correct?
second,when I create a instance,there will be meter data created in the
mongodb as "resource" and "meter",but for volume ,there is no any data
about volume in the db,so why ?Is there something wrong with my devstack
or there is configuration file should be modified?
third,I can only see cpu,disk,and network info for instance in the meter
data by now ,but there is no memory info,so why?
thanks
