JSON 输出数据格式
使用 json 输出数据格式（序列化器）来格式化 Telegraf 指标并将其输出为 JSON 文档。
配置
[[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"
示例
标准格式
{
"fields": {
"field_1": 30,
"field_2": 4,
"field_N": 59,
"n_images": 660
},
"name": "docker",
"tags": {
"host": "raynor"
},
"timestamp": 1458229140
}
批量格式
当输出插件需要一次发出多个指标时，它可以使用批量格式。批量格式的使用由插件决定 - 请参考特定插件的文档。
{
"metrics": [
{
"fields": {
"field_1": 30,
"field_2": 4,
"field_N": 59,
"n_images": 660
},
"name": "docker",
"tags": {
"host": "raynor"
},
"timestamp": 1458229140
},
{
"fields": {
"field_1": 30,
"field_2": 4,
"field_N": 59,
"n_images": 660
},
"name": "docker",
"tags": {
"host": "raynor"
},
"timestamp": 1458229140
}
]
}
