Service Virtualization

Hi Team-

We are trying to automate the services start/stop deployed in the environment and would like to know if there is any database that holds all the service and their start/stop status that we can use it actually to monitor/update based on the requirement.

Thanks,

Chaitanya

You can look at the VSE_METRIC_EVENTS table to get a snapshot status of services (UP, DOWN), then periodically re poll it to see if status' are changed.  This status is in the ACTION column.  

Hi,

Virtual service group tag is not found in this table. Will it be stored in any other table? If so please share the table name.

Apologies, I was not understanding your question properly:

Mark is right, and you can also look at these reports:

Virtual Service Metrics Reports - DevTest Solutions - 10.1 - CA Technologies Documentation 

You can also use the LISA Invoke API VSE call to get a xml or json representation of the VSE status (all services), use this as a baseline, then periodically re run the API and if things change do your actions accordingly

http://<portal_url>:1505/api/swagger

http://<portal_url>:1505/api/Dcm/VSEs/<vse_name_>

GET /VSEs/{serviceName}

Implementation Notes

The property "status" in the response can be: "0", the virtual service has been created, but not initialization yet; "1", the virtual service is in its startup sequence; "2", the virtual service is up and running; "3", the virtual service is in its shutdown sequence; "4", the virtual service has been shut down; "5", a virtual service is registered but cannot be run.

Hello Mark,

But this is not going to solve problem. I think, Chaitu want to do some kind of value add in which they can stop or run the services running over console without human intervention.

Is this can be achieved? Any guidance or idea, please?

Write a script...a test to initiate the API call for state of the VSE, compare the statuses of services to the prior baseline (can store prior baseline in SMM), if any service is down, invoke the service start API to restart it.  This is all automatic with a little programming in the test step/utility

Thanks Mark. This sounds good.

One thing, you are saying to invoke service Start API to restart it.

Can you please tell , is this a step? if we have to write script in test step then what parameters we have to give.

If you can provide a example would be helpful.

Cheers..

Take a look at the Swagger API spec

it can be accessed from the http://<devtest_registry_server>:1505/api/swagger url, here you can see the whole spec for VSE, including REST calls to stop/start target services

Thanks Mark, We will have a look at this and see if this is working out

Hi Mark-

I am looking at the swagger API, but I could see all of the API's are returning no content and when I am noticing the URL as below instead of the original server. Any Idea?

http://localhost:1505/api/Dcm/CoordinatorServers

Hello Chaitu,

Instead of localhost , you must use the IP or server where VSE is running. e.g

http://10.59.151.105:1505/api/swagger/

Please try it.

Cheers..

Hello Mark,

Thanks for it. Can you tell me is there any REST API with help of which we can get services running under particular group tag?

I am not able to see any in above link.

Cheers..

The swagger api does not have any calls based on group tag, but you should be able to use the high level VSE call, then execute an xpath query against the result to get servicres by grouptag.

Alternatively you can query the database table(s)
