Hi,
I am trying to push metrics to M3DB using coordinator remote write API.  

Scenario: we use need to use a push mechanism to send the metrics to M3DB. For this, we are using the M3DB coordinator. For API testing, We are Using the Postman tool, to push the metric.

Post Body
{
  "namespace": "default",
  "tags": [
    {
      "name": "__name__",
      "value": "user_login"
    },
    {
      "name": "city",
      "value": "new_york"
    },
    {
      "name": "endpoint",
      "value": "/request"
    }
  ],
  "datapoint": {
   "timestamp": 1591691050,
    "value": 42.123456789
  }
}

Application is throwing error "error":"snappy: corrupt input" m3db

I guess (I may be mistaken) that Prometheus sends the data to remote write endpoints in a protobuf over HTTP format, you need a specific tool to push the data manually or just use Prometheus in your tests

Hi Madhu,

For the Remote Write Endpoint you'll need to snappy compress a protobuf message, more documentation is available here including an example pushing metrics with a Go client library used by a command line utility "promremotecli":
