InfluxDB configuration in Shunya

Config	Descriptions
Influx DB URL	url to the Influx DB instance.
Database Name	Name of the database in which the data gets stored.

The configurations need to be set manually by the user before using the API's

For example:

A sample JSON snippet should contain

"influxdb" : {

"influxdbUrl": "",

"influxdbDBName": ""

For example:

A typical Influxdb configuration without security will look like this

"test-db" : {

"influxdbUrl": "http://148.251.91.253:8086/",

"influxdbDBName": "test-db"

}
