Graduate project for Golang courses (OTUS)

Main requirements available at https://github.com/OtusGolang/final_project

Technical requirements available at https://github.com/OtusGolang/final_project/blob/master/05-system-stats-daemon.md

Main features:

• GRPC server
• Simple client
• In-memory storage
• Supported OS: Mac OS, Linux
• Concurrency in getting snapshots

How to run daemon

go run cmd/daemon/main.go

go run cmd/daemon/main.go -port=50000

Available flags:

• port - GRPC server port (default 50005)

How to run client

go run cmd/client/main.go

go run cmd/client/main.go -port=50000

go run cmd/client/main.go -port=50000 -n=1 -m=5

Available flags:

• port - GRPC server port (default 50005)
• n - getting stats frequency (in sec, default 5)
• m - average stats interval (in sec, default 15)

How to build daemon

go build -v -o ./bin/daemon ./cmd/daemon && ./bin/daemon -port=5000

How to build client

go build -v -o ./bin/client ./cmd/client && ./bin/client -port=5000 -n=1 -m=5

Configs

Are available in configs/config.yaml

In "stats" group they are means to get (true) or not to get (false) specified kind of statistics

For example

• get only load average stats

stats:
  loadavg: true
  cpu: false
  disk: false
  nettop: false
  netstat: false

• don't get any kind of stats (by pass mode)

stats:
  loadavg: false
  cpu: false
  disk: false
  nettop: false
  netstat: false
