JSON output data format
This page documents an earlier version of Telegraf. Telegraf v1.21 is the latest stable version. View this page in the v1.21 documentation.
The json output data format serializes Telegraf metrics into JSON documents.
Configuration
[[outputs.file]]
## Files to write to, "stdout" is a specially handled file.
files = ["stdout", "/tmp/metrics.out"]
## Data format to output.
## Each data format has its own unique set of configuration options, read
## more about them here:
## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md
data_format = "json"
## The resolution to use for the metric timestamp. Must be a duration string
## such as "1ns", "1us", "1ms", "10ms", "1s". Durations are truncated to
## the power of 10 less than the specified units.
json_timestamp_units = "1s"
Examples
Standard format
{
"fields": {
"field_1": 30,
"field_2": 4,
"field_N": 59,
"n_images": 660
},
"name": "docker",
"tags": {
"host": "raynor"
},
"timestamp": 1458229140
}
Batch format
When an output plugin needs to emit multiple metrics at one time, it may use the batch format. The use of batch format is determined by the plugin – reference the documentation for the specific plugin.
{
"metrics": [

"field_1": 30,
