telemetry task

This repo contains implementation of following components:

• sink
• sensor
• decrypt (for testing purpose)

Requirements

• GO 1.23
• Docker(optional) for proto rebuild
• OpenSSL

Installation

Clone the repo

git clone https://github.com/DmytroMaslov/telemetry-task.git

Generate certificates

make gen-cert

Build binary

make build

Run the sink

make run-sink

or

./tmp/bin/sink --config  ./artifacts/sink/config.yaml

here:

config - path to configuration file in yaml format

example of configuration:

bind_address: "localhost:8080"
file_path: "./tmp/metrics.txt"
buffer_size: 1024
flush_interval: 100
rate_limit: 1048576
cert: ./certs/server-cert.pem
key: ./certs/server-key.pem

here:

• file_path - file where metric data will be collected
• buffer_size - size of sink internal (in memory) buffer; in bytes
• flush_interval - how often data from buffer is flushed to disk; in milliseconds
• rate_limit - max input flow rate in bytes/sec
• cert - path to cert
• key - path to key NOTE: if cert or key are empty or do not exist sink will run without TLS

Run the sensor

make run-sensor

or

./tmp/bin/sensor --addr localhost:8080 --name sensorName --rate 100 --cert=./certs/ca-cert.pem

here:

• addr - address of sink server
• name - name of the sensor
• rate - metrics per second
• cert - path to cert file NOTE: if cert is empty or does not exist, sensor will be run in insecure mode

Decrypt result

make decrypt

or

./tmp/bin/decrypt --input=./tmp/metrics.txt --output=./tmp/metrics_decrypted.txt

here:

• input - path to file with encrypted data
• output - path to file where decrypted data will be saved
