InfluxDB CLI cookbook

You can use the influxdb_iox command line tool to interact with the server in various ways

Ports

To connect on a different port, use the --host argument:

# connect to localhost on port 8083 (rather than default of 8082)
$ influxdb_iox --host http://localhost:8083  <command>

List all namespaces

# Connects to port 8082 (gRPC by default)
$ influxdb_iox debug namespace list
[
  {
    "id": "1",
    "name": "26f7e5a4b7be365b_917b97a92e883afc"
  }
]

List Schema in a Namespace

$ influxdb_iox debug schema get 26f7e5a4b7be365b_917b97a92e883afc
{
  "id": "1",
  "kafkaTopicId": "1",
  "queryPoolId": "1",
  "tables": {
    "mem": {
      "id": "2",
      "columns": {
        "time": {
          "id": "10",
          "columnType": 6
        },
        "host": {
          "id": "16",
          "columnType": 7
        },
        "available": {
          "id": "17",
          "columnType": 1
        },
        "wired": {
...

Alternately you can use show tables using SQL (see sql cookbook for more details):

$ influxdb_iox query 26f7e5a4b7be365b_917b97a92e883afc 'show tables'
+---------------+--------------------+------------+------------+
| table_catalog | table_schema       | table_name | table_type |
+---------------+--------------------+------------+------------+
| public        | iox                | cpu        | BASE TABLE |
| public        | iox                | disk       | BASE TABLE |
| public        | iox                | diskio     | BASE TABLE |
...
| public        | information_schema | columns    | VIEW       |
+---------------+--------------------+------------+------------+
