| [[outputs.iotdb]] |
| ## Configuration of IoTDB server connection |
| host = "127.0.0.1" |
| # port = "6667" |
| |
| ## Configuration of authentication |
| # user = "root" |
| # password = "root" |
| |
| ## Timeout to open a new session. |
| ## A value of zero means no timeout. |
| # timeout = "5s" |
| |
| ## Configuration of type conversion for 64-bit unsigned int |
| ## IoTDB currently DOES NOT support unsigned integers (version 13.x). |
| ## 32-bit unsigned integers are safely converted into 64-bit signed integers by the plugin, |
| ## however, this is not true for 64-bit values in general as overflows may occur. |
| ## The following setting allows to specify the handling of 64-bit unsigned integers. |
| ## Available values are: |
| ## - "int64" -- convert to 64-bit signed integers and accept overflows |
| ## - "int64_clip" -- convert to 64-bit signed integers and clip the values on overflow to 9,223,372,036,854,775,807 |
| ## - "text" -- convert to the string representation of the value |
| # uint64_conversion = "int64_clip" |
| |
| ## Configuration of TimeStamp |
| ## TimeStamp is always saved in 64bits int. timestamp_precision specifies the unit of timestamp. |
| ## Available value: |
| ## "second", "millisecond", "microsecond", "nanosecond"(default) |
| timestamp_precision = "millisecond" |
| |
| ## Handling of tags |
| ## Tags are not fully supported by IoTDB. |
| ## A guide with suggestions on how to handle tags can be found here: |
| ## https://iotdb.apache.org/UserGuide/Master/API/InfluxDB-Protocol.html |
| ## |
| ## Available values are: |
| ## - "fields" -- convert tags to fields in the measurement |
| ## - "device_id" -- attach tags to the device ID |
| ## |
| ## For Example, a metric named "root.sg.device" with the tags \`tag1: "private"\` and \`tag2: "working"\` and |
| ## fields \`s1: 100\` and \`s2: "hello"\` will result in the following representations in IoTDB |
| ## - "fields" -- root.sg.device, s1=100, s2="hello", tag1="private", tag2="working" |
| ## - "device_id" -- root.sg.device.private.working, s1=100, s2="hello" |
| convert_tags_to = "fields" |
