Parsing json-object with dot in their name?

[jounivarjonen]

Hi, I've been trying but not succeeding to parse json data as follows:

{
  "version" : "4.0.0",
  "gauges" : { },
  "counters" : {
    "TransferManager.downloads.queue" : {
      "count" : 2
    },
    "TransferManager.forwards.queue" : {
      "count" : 0
    },
    "TransferManager.transfers.active" : {
      "count" : 5
    }
  },
  "histograms" : { },
  "meters" : 
    {
    "TransferManager.downloads.failed" : {
      "count" : 1012,
      "m15_rate" : 0.0031013012486067124,
      "m1_rate" : 0.020422990475295447,
      "m5_rate" : 0.008097230208595894,
      "mean_rate" : 0.0013440113841602863,
      "units" : "events/second"
    },
    "TransferManager.downloads.succeeded" : {
      "count" : 20407,
      "m15_rate" : 0.02925335031554721,
      "m1_rate" : 0.019210550446002225,
      "m5_rate" : 0.025774833786456255,
      "mean_rate" : 0.027102016120216895,
      "units" : "events/second"
    },
    "TransferManager.forwards.failed" : {

Didn't paste the whole json but the idea is that I would like to parse that data from the endpoint without modifying it. I got this working by changing all dots to _

My config before changing the JSON:

---
modules:
  default:
    metrics:
    - name: execution_status
      type: object
      path: '$.meters["TransferManager.downloads.failed"]'
      labels:
        count: '.count'
      values:
        status: 1`

This didn't work. It says that Transfer Manager cannot be found.

This works after changing the data:

---
modules:
  default:
    metrics:

    - name: Failed_Downloads
      type: object
      help: Metrics for Failed Downloads 
      path: "{.meters.TransferManager_downloads_failed}"
      labels:
        environment: xxxxxx
        metrics: transfer statistics
        system: xxxxxxx
        owner: xxxx
        count: '{.count}'
      values:
        status: '{.count}'

I would love to get things parsed without first fetching the JSON and then modifying and after that serving modified data from localhost to the scraper.

Probably it's just me that doesn't understand but wanted to ask you guys.

Delete this is just me being stupid.

Cheers
