Telegraf, a server-based agent, collects and sends metrics and events from databases, systems, and IoT sensors. Written in Go, Telegraf compiles into a single binary with no external dependencies–requiring very minimal memory.

How To Monitor System Metrics with the TICK Stack on Ubuntu 16.04 | DigitalOcean
Install as Win Service
After install you get:
Follow the steps on github, make a agent conf, telegraf.conf
Read a file in and append on to a file out, keep rolling in test mode
Test mode
In and out file, log and folders
It reads the text file and appends to the out file, in interval in the [Agent] section
Install as Windows Service when you are happy / view github ps1
You get this service
log file
and output file is growing
Lets explorer the agent parameters and store them in the config file.
Example edit log mode
quiet = false # quiet: True, Log only error level messages, or false.
Example Agent section
[agent]
interval = "30s"
round_interval = true
metric_batch_size = 1000
metric_buffer_limit = 10000
collection_jitter = "0s"
flush_interval = "30s"
flush_jitter = "5s" precision = ""
debug = true
quiet = false # quiet: Log only error level messages.
logfile = "C://Program Files//Telegraf//telegraf-1.32.0//telegraf.logs"
logfile_rotation_max_size = "10MB"
logfile_rotation_max_archives = 10RabbitMQ ouput
Lets assume the same json input file
Stop the service and update the \conf\telegraf.conf with above file.
Make a amqp user and password in RabbitMQ.
Start the Telegraf service and verify logs
Now verify the new exchange in RabbitMQ
Make a queue and bind to the exchange “telegraf”
Verify that you are receiving data on the queue from.telegraf with above exchange.
Telegraf logs

Inspect one message.

Disconnect it and see if if it reconnects?
Logs Telegraf
All good, perfect.
Influxdb output, we had disk as input
# Read metrics about disk usage by mount point
[[inputs.disk]]
## Ignore mount points by filesystem type.
ignore_fs = ["tmpfs", "devtmpfs", "devfs", "iso9660", "overlay", "aufs", "squashfs"]
We wrote the disk output
# Configuration for sending metrics to InfluxDB 2.0
[[outputs.influxdb_v2]]
urls = ["http://xx.xxx.xxx.241:8086"]
## Token for authentication.
token = "make a token in inflyxdb for the bucket"
## Organization is the name of the organization you wish to write to.
organization = "lima"
## Destination bucket to write into.
bucket = "testTelegraf"
Choose all parameters for c:

Agent, we have spent some time here and this config is straight forward.
After generating a config with and input and output, telegraf.conf had a big section on processors and smaller section on aggregator.
# make a new conf with input cpu and output file
