RDO Virtual Get Together
by Amy Marrich
Sorry for the late email but we thought it might be fun to have a virtual
get together during the PTG or the week after. I've put together a few
different days on a Doodle for 17:00 UTC as this would be about dinner time
in EMEA, breakfast, brunch or lunch in the Americas, and late night snack
for APAC.
If you're interested in joining us please vote in the doodle for your
preferred date.
Thanks,
Amy Marrich (spotz)

TripleO Monitoring Tool/Method
by Khodayar Doustar
Hi everybody,
I am searching for a good and useful method to monitor my 40 nodes cloud.
I have tried
- Prometheus + Grafana (with
https://github.com/openstack-exporter/openstack-exporter) but it cannot
monitor nodes load and cpu usage etc.
and
- Gnocchi +Collectd + Grafana but it enforces unbelievable load on nodes
and make the whole cloud completely unusable!
I've tried to use Graphite + Grafana but I failed.
Do you have any suggestions?
P.S. Where can I find good documentation for TripleO over CentOS? Redhat's
is somehow restricted to its own RHOSP. This website is down:
http://tripleo.org/
Thanks,
Khodayar

Re: [rdo-users] TripleO Monitoring Tool/Method
by Matthias Runge
Hi.
for STF deployment, you can follow the doc you linked.
Legacy refers to "old" monitoring, meaning ceilometer, aodh and gnocchi.
Depending on your setup, you'll also enable ceilometer for OpenStack
usage reporting.
Because you also would like to use cloudkitty, you will have to enable
gnocchi (iirc.) That is something you'll have to check.

Creation of Compute instance always fails on RDO openstack
by Tony Waria
I'm running a centos 7 VM. On that VM I have installed RDO openstack.
I'm able to instantiate a network. However when I create Compute Instances,
I'm constantly getting this error message -

Appreciate your help with this.
Thanks
