Right now, when Scaling dictates the instantiation of a new VM, there is a lag time between the VM being instantiated and the VM connecting to Zabbix. While the Engine waits for this to happen, it throws an exception about the fact that the number of measurements requested does not equal the number of measurements received. No processing happens when this exception occurs - the cycle is skipped until the next interval.

I see several issues with this. Many VMs can be sacrificed on account of a single new instance. Or, what if that VM has an issue and never comes online for some reason? And the other VMs are pegged out and desperately need to scale?

I could be wrong and maybe it needs more design thought, but I am thinking that once a VM is instantiated, the engine needs to subscribe to a queue. And when that VM is connected to Zabbix, it can send a message to the queue that the engine receives, and a flag or state condition is set to mark that VM as "eligible to participate" for purposes of counters and measurements towards scaling policies.

If I put 2 connection points in my VDU Components, and launch the descriptor, it should be assumed that the MINIMUM number of instances i want to go out with initially is 2.

If I apply Elasticity with a set of SCALE_OUT and SCALE_IN parameters, what is happening right now is that SCALE_IN will knock the instances down to a single instance. This is because in the class DecisionTask.java, the code has a ">1", which ensures that not all of the instances are killed off and that a single instance will always be remaining.

I went in and attempted to change the code (DecisionTask.java) such that instead of using a hard-coded 1 value, I would use the number of initial connection points. What I realized is that the getConnection_points call returns is a dynamic value of the at-runtime number of connection points; not the number we went out with and deployed initially.

After poking around and realizing that we really don't seem to save off that initial number of connection points in the descriptor, so that we can use it as a floor on the SCALE_IN policy, I decided to write it up for discussion.

Hi, we are trying to autoscale the SIPp network service. The NSD used to deply the network is attached. We are using Open Baton version 5.2.1 and Zabbix version 3.0.22. The autoscaling engine seems to be expecting a Json array but is getting Json object. The logs for the autoscaling engine in ase.log give the following error:

2018-12-11 14:29:43.915 INFO 8755 --- [TaskScheduler-4] o.o.a.core.detection.DetectionEngine : Get monitoring plugin with following parameters:
2018-12-11 14:29:43.923 ERROR 8755 --- [TaskScheduler-4] o.o.a.core.detection.task.DetectionTask : Exception occured while getting measurements -> Expected a com.google.gson.JsonArray but was com.google.gson.JsonObject, Trying again next time...

Your help would be much appreciated.
Thanks

I am running many other components just fine (nvfo, generic-vnfm, zabbix plugin, et al).
I compiled the source code - version 1.2.4-SNAPSHOT.jar.

Cannot seem to even get the service to start. I can log into the dashboard at the IP and Port (8443) just fine. But when I start the autoscaling-ase service up, I see that it cannot connect and finally throws an exception.

I know this ip and port work, because I am logged into it on the dashboard. Of course aside of that, a netstat tln does show port 8443 listening. I have tried localhost, and have also tried the actual IP of the instance.

I did put in a external driver.properties file for the openstack4j plugin and set the values on disable-ssl-certificate-check to both false and true, to see if maybe it was an ssl error. I still think it could be an ssl error, but maybe it's not.

At this point, I cannot get the autoscaling engine to work until and unless I can figure out a solution for this. I'm out of clues, so I'll post this.

Hi, we're using the bootstrap script to install OB on a Linux Ubuntu 16.04LTS image in an esxi VM. All goes well, but when starting the autoscaling service service, we get the error:

Hello,

With given NSD example, NetworkServiceRecordRestAgent returns invalid_token error. I am attaching our sample NSD and autoscaling logs.
sample_nsd.txt
autoscale.txt

The file committed and the start script use the name : ase.properties; the release uses openbaton-ase.properties.

The last one should be used.

I have an NSD with two VNFs (A & B). A has an FM Policy on it, B has an AutoScaling policy on it.

When I launch the NSD,

• A scales due to the FM Policy, and the VNF is in state "SCALE".
• B is in START state, as everything properly proceeds through INSTANTIATE, CONFIGURE and START.
• The NSD is in State "SCALING".

Then, the AutoScaling thread keeps throwing an API exception because the NSR State is not ACTIVE, as shown below:
"message": "NetworkServiceDescriptor must be in ACTIVE state"
}

If you start NFVO and then start AES, AES produces error because the state of the NSR is NULL (initially). What it probably should do, is to notice that the NSR ID is NULL, and wait for for an NFVO event that tells the AES whether the NFVO has moved it to the ACTIVE state, or into a state of ERROR

Unfortunately, the AES never starts functioning. I believe this is related to the fact that in the Dashboard, I see the following in the Event Listing:

Name: Subscription:ERROR
Endpoint: http://localhost:9999/elasticity-management/ERROR
Event: ERROR
This is probably a separate issue.

I am still getting the following error but the credentials don't seem to be the problem.

Inside Zabbix, my instances are automatically getting registered and are being monitored. Initially, I thought that the ASE uses the createThreshold method so I had configured the send_notification script and was trying to add an Action but I was informed that it doesn't use that. I later realised it uses the monitoringPluginCaller and the plugin SDK has already been imported.

Do I need to manually use the methods create PM Job and query PM Job in order to get metrics from the Zabbix plugin? I see examples of how to do this but I am not sure which file to do it in. Please let me know if there are configurations I need to do either on the Zabbix server or plugin to get data for the ASE.

Thank you in advance.

I'm trying to build an image of openbaton with ASE in a Packer image that is then deployed in OpenStack.

For some reason ASE won't startup in the new image, though the NFVO and Generic NFVM will.

I see many of these in the ASE log:

2018-01-02 22:43:53.389 ERROR 2023 --- [main] org.openbaton.sdk.api.util.RestUtils     : Status expected: 200 obtained: 401

Any thoughts on this?

Thanks.
