REST API access to more variables on the Data Layer

[E_Stapel]

Hello everyone,

is it possible, to access more than one variable from the CtrlX Data Layer with one GET-Request ?

Thank you in advance!

Please have a look to the post "Read/write GVL as a block using REST API".

Hello @E_Stapel ,

Yes, it is possible to execute multiple operations using a single request with the bulk endpoint.

Here is an example curl request generated from the linked Swagger UI.

curl -X 'PUT' \
  'https://127.0.0.1:8443/automation/api/v2/bulk?type=read' \
  -H 'accept: application/json' \
  -H 'Authorization: Bearer eyJhbGciOiJFUzM4NCIsInR5cCI6IkpXVCJ9.eyJleHAiOjE3MTc1MzcwNjEsImlhdCI6MTcxNzUwODI2MSwiaWQiOiIxMDAwIiwibmFtZSI6ImJvc2NocmV4cm90aCIsIm5vbmNlIjoiZTY2ZDBjNDEtYTE1Zi00NTI0LWI3YjAtNmFjYjBhYzA1NjM5IiwicGxjaGFuZGxlIjowLCJyZW1vdGVhdXRoIjoiIiwic2NvcGUiOlsicmV4cm90aC1kZXZpY2UuYWxsLnJ3eCJdfQ.UrlnBCcFUJHGWHUuBBRS1JiqXYOfrldkpH7s_6wVxyuNNliBADg8_NTUEoWFPnhP8rrRQ1Xy0N_jZK5dqYu1_aeeh3-v0byvdED8u6Sx8MkA8wYRxG6rPNWd-qCHLKUv' \

  -d '[
  {
    "address": "framework/metrics/system/cpu-utilisation-percent"
  },
  {
    "address": "framework/metrics/system/memused-percent"
  }
]'

Here is the response body from the ctrlX REST API server.

[
  {
    "address": "framework/metrics/system/cpu-utilisation-percent",
    "result": "DL_OK",
    "timestamp": "133619818963378058",
    "type": "double",
    "value": 4.7
  },
  {
    "address": "framework/metrics/system/memused-percent",
    "result": "DL_OK",
    "timestamp": "133619818963386645",
