[Openstack] [ceilometer] Monitoring resources outside OpenStack

Hi,
I am trying to use ceilometer to monitor a physical switch/router connected to a compute node. Is it possible to achieve using ceilometer pollster?
If yes, I have few questions.
1. From where do I get the resource ID for the device. (Since router/switch is outside of OpenStack)
2. I am planning to get the credentials of the device from ml2/neutron conf. Will it be possible to read the conf from ceilometer service.
3. To create a new metric is it enough to create entry in /etc/ceilometer/pipeline.yaml?
Regards,
Pradeep. S

Hi Andreas,
i managed to have them created by deleting the network and recreating it (using neutron command line).
Maybe i had something not setup correctly when i first created the network or somethin went wrong back then.
Nevertheless, it works now.
Thanks for offering your help!
Greetings
Thomas

Hi Thomas,
could you please share your neutron-server and neutron-openvswitch-agent configuration files?
Did you set debug to true in your configuration and restarted the neutron-openvswitch-agent on your controller node?

But the tunnel interface is created correctly, so that the compute node is able to send traffic to the network node (which is then discarded).

Yes it's called overlapping IPs.
You can turn this off if you would like.
neutron.conf:# Enable or disable overlapping IPs for subnets
allow_overlapping_ips = True
Hopefully this help.

Hi
I have a question about network configuration. When I list networks on the openstack controller, there are i.e. four networks with the label "net1" with different id's of course but 3 of them have the same subnet defination : 10.0.0.0/24 as seen in the list below. ( my collegues have been busy).
Every subnet has a different tenant ID.
Is this the default behaviour in Openstack? I.e. the name will be 'net1' and the subnet created will be "10.0.0.0/24" ?
If I source as admin, the list is like this:

Hi,
Recently "something" changed in my openstack env. but I can't figure out what happened !
When I launch an instance , it will be created normally and get the IP's on the configured subnets:
i.e.
fixed_ip_address -- 10.100.100.7
floating_ip_address -- 157.157.8.139
when I ping the external IP i.e. 157.157.8.139 it will respond with the other IP i.e. 10.100.100.7 !!
This is different from the previous behaviour (several weeks ago) and causes problems of course.
Can you please give me feedback on this problem?
Best regards
Yngvi

I'm working on a POC using Horizon and have successfully created some dashboards and panels. Next up is creating some custom API's. Is there any documentation anywhere on doing this? I tried looking at some of the existing api's in the api folder and mimicking what they are doing but my panel isn't seeing the api that I made. Does it need registered somewhere first?
Thanks.
Donald
