Topology APIs

Learn how to retrieve Topology APIs and what they are used for.
The Topology data can also be retrieved using manual APIs. This page lists the available APIs and their functions.
To get to these APIs, complete these steps:
  1. Click the
    User
     icon in the upper right and select
    Developer Console
    .
  2. In the
    Application
     field, select
    mcmp-nextgen
    .
  3. In the
    Service
     field, select
    mcmp-impactanalysis-api-service
     (for fetching impact analysis data) or
    mcmp-topology-api-service
     (other).

Context Topology with pagination

This API retrieves the Topology data associated with the context values provided in the request body. Multiple parameters can be provided to filter the results.
  • Method:
     POST
  • Endpoint:
    /data
  • Request body:
     All these parameters are optional. 
    {
   filters : {
     provider : [],
     account : [],
     network : [],
     tags : [],
     fetch_additional_resources : true
  }
}
  • Parameters:
    • offset:
       The number of records from the beginning of the list to skip.
    • limit:
       The maximum number of records that you want to retrieve. The default is 100.

Fetch impact analysis data

To fetch the impact analysis data for a specific node, use the following API:
  • Method:
     POST
  • Endpoint:
    /predict
  • Parameters:
     All these parameters are optional.
    • data:
       The IDs of the nodes that you want impact analysis data for in the following format: 
      {
     resourceId : [
         arn:aws:eks:us-west-1:753022563888:cluster/eks-multinode-demo/namespaces/boutiqueappdemo/pods/a8d10a81-5cd1-4c4c-9221-b7f21e954914 ,
         arn:aws:eks:us-west-1:753022563888:cluster/eks-multinode-demo/namespaces/boutiqueappdemo/pods/4c3c2a58-40e1-4bc5-b925-70874ddec533 ,
         arn:aws:eks:us-west-1:753022563888:cluster/eks-multinode-demo/namespaces/boutiqueappdemo/pods/aa09a22d-dd85-4977-bbcc-20983d1c7212 
    ]
}
  • Response for a single node:
     
    {
   success : true,
   resultMsg : {
     ImpactAnalysis : [
      {
         impactedResource :  arn:aws:ec2:us-west-2:554041277834:vms\\/i-0b1619a6388215b91 ,
         impactedPercentage : 61.63,
         impactClass :  B 
      },
      {
