Benthos 按照input, pipeline ,buffer,conditions,ouput 这个几个大类,为我们提供了
方便的分析metrics,支持json 格式同时可以暴露为 statsd、prometheus 格式的数据metrics
当前的metrics 如下:
Input
input.count
: The number of times the input has attempted to read messages.input.received
: The number of messages received by the input.input.batch.received
: The number of message batches received by the input.input.connection.up
input.connection.failed
input.connection.lost
input.latency
: Measures the roundtrip latency from the point at which a
message is read up to the moment the message has either been acknowledged by
an output or has been stored within an external buffer.
Buffer
buffer.backlog
: The (sometimes estimated) size of the buffer backlog in
bytes.buffer.write.count
buffer.write.error
buffer.read.count
buffer.read.error
buffer.latency
: Measures the roundtrip latency from the point at which a
message is read from the buffer up to the moment it has been acknowledged by
the output.
Processors
Processor metrics are prefixed by the area of the Benthos stream they reside in
and their index. For example, processors in the pipeline
section will be
prefixed with pipeline.processor.N
, where N is the index.
pipeline.processor.0.count
pipeline.processor.0.sent
pipeline.processor.0.batch.sent
pipeline.processor.0.error
Conditions
condition.count
condition.true
condition.false
Output
output.count
: The number of times the output has attempted to send messages.output.sent
: The number of messages sent.output.batch.sent
: The number of message batches sent.output.connection.up
output.connection.failed
output.connection.lost
使用说明
实际参考如下配置,修改type 为需要的类型
metrics:
type: http_server
prefix: benthos
http_server: {}
prometheus: {}
statsd:
address: localhost:4040
flush_period: 100ms
network: udp
