Re: [openstack-dev] [ceilometer] ceilometer Floatingip Pollster change

[gord chung]

i guess i should probably add that the current pollster doesn't work 
because of limitation in nova api[1].
if we want to support discovery of whether nova-network or neutron is 
used, the existing pollster and nova-api still needs to be fixed.

3. Are there any other concerns regarding this change that we should

Any feedback appreciated,

Yea I think since the existing pollster doesnt return any data, it
shouldn't be disruptive to replace with neutron api based fip pollster as i
indicated.
We can always add endpoint discovery at a later time when nova api gives
the expected fip data, so we can poll nova/neutron api's when available.
For now, I feel we should go ahead with the proposed implementation[1].

Any objections?

[openstack-dev] [ceilometer] ceilometer Floatingip Pollster change

[Pradeep Kilambi]

Ceilometer floatingip pollster currently polls the nova api to get the
floating ip info periodically. But due to limitations in the nova api as
listed in this bug[1],
the data ceilometer receives isn't all that useful. Nova doesn't return
this info for all tenants. There has been some work in juno time frame but
it was
reverted due to the fact that the nova api logs were being spammed [2].

Due to these concerns, the proposal now is to use the neutron api to get
this data as proposed in this patch[3]. What we would like to know is,


1. Is the data gathered from current floating ip pollster being used? if so
how and what context ?

2. This might only be an issue for pure nova-network scenario, but even
that i'm not sure how useful the current data we gather is?

3. Are there any other concerns regarding this change that we should
discuss?

Any feedback appreciated,
