system-monitoring

A small monitoring daemon that sends info about server's health via protobuf

Requirements

• one of the supported OS (MacOS, Linux)
• Golang v1.16 or Docker (only for Linux)

Functionality & Features

• Calculating:
  • Load average (MacOS, Linux)
  • CPU load (MacOS, Linux)
  • Disks load (Linux only)
• Unit-tests
• Integration tests
• Simple client for daemon
• Some statistics works under different OS (MacOS, Linux)

Tested on

• Ubuntu 18.04
• Ubuntu 20.04
• Fedora 34
• MacOS 11

Building

Locally

• To build server, type make grpc-server

• To build a client, type make grpc-client

Docker

• To build server docker image, type make docker

Configuring

Server

• To disable grabbing & sending statistics, edit config.yml

• To run server on different port, use -p option: sudo ./grpc-server -p 8089

• All CLI options are available by running server with -h option

Client

• To run client on different port, use -p option (default port is 8088): sudo ./grpc-client -p 8089

• To get data averaged for, for example, 5 seconds, use -n option (default is 3 sec): sudo ./grpc-client -n 5

• To get messages from server every, for example, 4 seconds, use -m option (default is 3 sec): sudo ./grpc-client -m 4

• All CLI options are available by running server with -h option

Running

Directly

• To run a server, build a server binary and start it with root privileges (we need them to examine FS Utilization) sudo ./grpc-server

• To run a client, build a client binary and then start it: ./grpc-client

In Docker

• To run a service in docker, type make docker-server

• To run a client in docker, type make docker-client

Developing

• To regenerate GRPC implementation, type make grpc-autogen

• To run integration test locally, type make integration-test

• To run unit tests locally, type make test
