cloud discovery

Hello 

 

When I create a cloud discover job  ( 2 jobs are created).  (one for api and one for IP discovery)

When I create different cloud discovery jobs for different datacenters  (see picture)

my understanding is, that each   "AWS_sched_*-VM_schedule" job will get all  IP addresses from all datacenters belong to  the "service account" / "account_id"

So the 2  "AWS_sched_*-VM_schedule" jobs do the same work,  I can delete one of them?  (keep the last one)

Is this correct?

Hi,

The schedules that discover Cloud Resources will indeed collect the IP addresses of all the VM instances but the Configuration Item schedules will execute horizontal discovery on those IP addresses. If you remove the Configuration Item schedules, no horizontal discovery will be performed.

 

Basically with Cloud Discovery you will discover instances using the API and Configuration Item discovery will discover the servers running on those instances.

Hello, and thanks for  the feedback. I think there is a misunderstanding. 

On the picture I have 2 horizontal discoveries: 

  • AWS_sched_04- VM schedule
  • aws_sched_05- VM schedule

Both belong to the same service account. I assume that the lists of IP adresses given to the jobs are the same. 

So the 2 jobs do exactly the same horizontal discovery and I can delete one of them.

Hi,

OK, I see. But they seem to be tied to different datacenters? One for west and one for central?

Not sure how that works for AWS. But for Azure you would only get vm instances hosted in the specific datacenter.

Hello @Detlef Biederma 

When you do cloud discovery, 2 schedules gets created one for the data centers and another for the VMs.

a. For VMs - you can discover virtual machines (VMs) during discovery of the cloud resources. Cloud Discovery performs a deep discovery of the virtual machines identified by the cloud schedule, using the IP addresses of the VMs.

b. Data centers - Service account-based discovery finds all the resources in a service account. This kind of discovery collects metadata using the cloud provider's APIs, then populates the Machine Instance CMDB table with basic attributes. Service account discovery has visibility into tags, which helps data reporting and workflow automation. For example, cloud events can be used to trigger discovery on-demand on target services. This mechanism helps Cloud Discovery to identify changes and automatically update the CMDB.
