Sample config.toml

# You can configure multiple customers.
[[customers]]
  # name must be unique across customers
  name = "servicex"
  email = "user1@email.com"
  # api key. Should be a long random string. This is the value of the telegraf header (default header name is 'Service-API-Key')
  api_key = "7ba4e75a"
  # Name of the influxdb database where the metrics for this customer should be stored.
  influx_db_name = "telegraf1"
  # Max number of batches that will be kept in-memory for each of the 'influx_hosts'. Beyind that batches with be dropped
  outgoing_queue_cap = 7000
  # Influxdb-routed maintains a retry queue for batches that it fails to send to InfluxDB backends.
  # retry_queue_cap is the max number of batches that can be kept in the retry queue (in-memory).
  retry_queue_cap = 10
  # list of InfluxDB hosts.
  influx_hosts = ["http://127.0.0.1:9086", "http://127.0.0.1:8086"]
  # The auth section needs to come at the end. This should be populated only if you enabled auth in influx-router
  # and set auth-mode to 'from-config'. Additionally you need to enable authentication by setting the 'auth-enabled' option
  # to the in the [http] section of the InfluxDB config. 
  [customers.auth]
      # influxdb user. Yo need to grant privilege to user 'user1' to database 'telegraf1'
      username = "user1"
      # influxdb password for user user1
      password = "password1"

Influxdb-router Usage

1. Without InfluxDB authentication enabled.

$./influxdb-router -config_file config.toml -api-listen-http-port 8080 -listen-http-port 8090

2. With the InfluxDB creds in config.toml and with InfluxDB authentication enabled in the backends.

$./influxdb-router -auth-enabled -auth-mode from-config -config_file config.toml -api-listen-http-port 8080 -listen-http-port 8090

3. config.toml with the InfluxDB creds not in config but in env and with InfluxDB authentication enabled in the backends. You can set the creds in environment in the following format.

$ export username_<name> = "user1"
$ export password_<name> = "password1"
<name> is the 'Name' attribute in the toml.


$ ./influxdb-router -auth-enabled -auth-mode from-env -config_file config.toml -api-listen-http-port 8090 -listen-http-port 8080

4. With SSL

$ ./influxdb-router -secure -config_file config.toml -api-listen-http-port 8080 -listen-https-port 8443 -ssl-server-cert <path to server cert> -ssl-server-key <path to server key>

5. With SSL and with ssl client cert authentication enabled (telegraf needs to be configured with client certs)

$ ./influxdb-router -secure -ssl-client-cert-auth -config_file config.toml -api-listen-http-port 8080 -listen-https-port 8443 -ssl-ca-server-cert <path to CA cert> -ssl-server-cert <path to server cert> -ssl-server-key <path to server key>
