2016-12-07 02:42:31 -0600 commented question ssh fails on VNF Instance

Thanks for the quick reply. I tried the nova show command

nova show VNF_SCALING

for vnf created by tacker but it displays nothing and gives error : No such ID or name present.

2016-12-06 02:18:54 -0600 asked a question ssh fails on VNF Instance

Hi , I have created a vnf using tacker. I have added a keyname to vnf descriptor for the vnf. However I am unable to ssh VNF from command line ,it gives error : Permission denied[Public Key].I have tried the command :

ssh -i keyname.pem -vvv ubuntu@IP.

If I try to use same key-pair for instance launched from Horizon , ssh works with above command. How do I resolve this issue?

Any help will be appreciated.

Is your alarm working? Check the AODH for alarm .... use command aodh alarm list and see the state of alarm

Finally got the solution , Modified tacker.conf .....Added hostname in ceilometer section , username,password,project,url in aodh_alarm section. Service running fine now :)

2016-11-30 00:04:28 -0600 asked a question Unable to add multiple conditions for scaling in Tacker (TOSCA file)

Hi , I have installed openstack nova,neutron,glance,keystone,tacker,ceilometer,aodh for newton version from the official openstack installation site. I am trying to perform scaling and orchestration using tacker,ceilometer,aodh . I am trying to create vnf with scaling condition such that :

i) If cpu utilisation higher than threshold then VNF should scale-out.

ii)if cpu utilisation less than threshold then VNF should scale-in.

For this I have used Tacker's TOSCA scaling template reference. However if I mention the above two conditions in VNF Descriptor , the 2nd condition overwrites condition 1 . I imply this because aodh shows only 1 alarm with 2nd condition. Testing with less CPU utilisation also gave same output. What can I do so that both condition should co-exist in VNF Descriptor and there is no overwriting?

2016-11-22 06:31:30 -0600 asked a question Tacker Error :Unauthorized


We have installed openstack with basic nova,neutron,glance,heat,horizon,keystone services from newton official tutorial . We have also installed tacker,ceilometer,aodh. We have created a scaling policy with tacker which should spawn a new VM when aodh alarm is captured (i.e certain event goes beyond threshold). However when alarm is triggered by Aodh , we get error at tacker server stating :

At An error occurred during processing the request :Request at ......

2016-11-14 09:12:32 -0600 asked a question Ceilometer a2ensite crashes Apache2

Hi , I am new to openstack community. I have installed the openstack services on my ubuntu 16.04 using newton manual from openstack install guide . All the services are up and running except for ceilometer and aodh. Ceilometer and aodh give me meter-list and alarm list output properly but otherwise show some problem like following:

When I enable ceilometer on Apache2 using a2ensite command , Apache2 crashes . However when I disable ceilometer , all services are back to normal working .

Also when I try to run curl -i -X GET "Localhost:8777" I get error : "The request you have made requires authentication , code:401 , title: Unauthorized"

How do I solve this error?
