Arvados

Bug #15734

Updated by Ward Vandewege over 5 years ago

Node manager drops a file called node.json in the container log collection, with an output like this: 

 <pre> 
 { 
     "created_at": "2017-04-12T04:37:11.016719000Z", 
     "crunch_worker_state": "busy",

     "ip_address": "10.26.64.21", 
     "job_uuid": null, 
     "kind": "arvados#node", 
     "last_ping_at": "2019-06-01T18:56:02.166756000Z",

     "nameservers": [ 
         "10.26.0.11" 
     ], 
     "owner_uuid": "qr1hi-tpzed-000000000000000", 
     "properties": { 
         "cloud_node": { 
             "price": 0.192, 
             "size": "Standard_D4s_v3" 
         }, 
         "total_cpu_cores": 4, 
         "total_ram_mb": 16018, 
         "total_scratch_mb": 32747 
     }, 
     "slot_number": 3, 
     "status": "running", 
     "uuid": "qr1hi-7ekkf-z6lokkesrtdw9ia" 
 } 
 </pre> 

 This information originates from the Arvados node record. That table is no longer used by a-d-c. We need the 'properties' section to be available in that file for container cost accounting. A-d-c should populate the node.json file like this: 

 <pre> 
 { 
     "properties": { 
         "cloud_node": { 
             "price": 0.192, 
             "size": "Standard_D4s_v3" 
         }, 
         "total_cpu_cores": 4, 
         "total_ram_mb": 16018, 
         "total_scratch_mb": 32747 
     }, 
 } 
 </pre> 

 instead of just dropping an empty file in the container logs.
