saido means monitor in Hausa

Demo

Installation

NOTE: We've currently only tested on Mac Os, Windows 11 and Linux Ubuntu 20.04 LTS

Installing Binary

Download latest binary for the target machine from Github Releases

Windows Cmd

REM Check your `PATH` 
path
REM Copy the saido binary to a directory that is on your `PATH`
copy <path_to_saido_binary> <path>

Windows Powershell

#Appends to existing path
$env:Path += ";<path_to_saido_binary>" 

Linux or Mac OS

#Add saido to your `.bashrc` or `.zshrc`
alias saido="<path_to_saido_binary>" 

#Or Copy binary to your bin directory
cp <path_to_saido_binary> /usr/local/bin 

Development

NOTE: !windows flag is our current specification of what unix means, see issue for why *_unix.go files will still attempt to run on windows.

Requirements

• Golang
• Docker
• Yarn
• Air

git clone https://github.com/bisohns/saido
cd saido
## Update dependencies
make dependencies

# Build and serve frontend
make app

# Modify generated `config-test.yaml` file and air would reload server

Usage

The simplest usage is running

# binary is downloaded and named as saido
saido --config <path_to_configuration_yaml_file> --port 3000 --verbose

Hosts

hosts

Supported hosts command

NOTE: The broad assumptions we make is that the host names are treated as unique.

• children - a list of hosts with host names

Setting up local connection to host

hosts:
  children:
    # Host with host name `localhost`
    'localhost':
        connection:
            # define `connection` with  `type` as `local` 
            type: local
        metrics:
            memory:
            disk:
            tcp:
            docker:
            uptime:
poll-interval: 10

Setting up ssh connection to host (with ssh username and password)

hosts:
   children:
   # Host with host name `192.168.166.167`
    '192.168.166.167':
      connection:
        # define `connection` with `type` as `ssh` 
        type: ssh
        # define `username` and `password` for connection to ssh server
        username: <username>
        password: <password>
      metrics:
        custom-ls: 'ls $HOME/app'
metrics:
  memory:
  disk:
  tcp:
  docker:
  uptime:
poll-interval: 10

Setting up ssh connection to host (with ssh private key and port)

hosts:
   children:
   # Host with host name `0.0.0.0`
     '0.0.0.0':
      connection:
        # define `connection` with `type` as `ssh` 
        type: ssh
        # define `username` and `port` and `private_key_path` for connection to ssh server
        username: <username>
        port: 2222
        private_key_path: 'path_to_private_key'
metrics:
  memory:
  disk:
  tcp:
  docker:
  uptime:
poll-interval: 10

Setting up ssh connection to host (with ssh a password protected private key)

hosts:
   children:
   # Host with host name `0.0.0.0`
     '0.0.0.0':
      connection:
        # define `connection` with `type` as `ssh` 
        type: ssh
        # define `username` and `port` , `private_key_path` and `private_key_passphrase` for connection to ssh server
        username: <username>
        port: 2222
        private_key_path: <'path_to_private_key'>
        private_key_passphrase: <private_key_passphrase>
metrics:
  memory:
  disk:
  tcp:
  docker:
  uptime:
poll-interval: 10

Metrics

metrics

Supported metrics command

NOTE: Custom metrics with commands can be added to the configuration file

• memory - for calculating memory usage
• disk- for calculating disk usage
• tcp - for getting tcp connection information
• docker - for getting docker container information
• uptime - for calculating uptime and idle time of the host

Setting Global metrics

hosts:
  children:
    'localhost':
        connection:
            type: local
    '0.0.0.0':
      connection:
        type: ssh
        username: <username>
        port: 2222
        private_key_path: '<path_to_private_key>'
# Metrics are defined on a global scope. Same level with the hosts
metrics:
    memory:
    disk:
    tcp:
    docker:
    uptime:
poll-interval: 10

Setting Local metrics

hosts:
  children:
    'localhost':
        connection:
            type: local
        # Metrics are defined within a host (localhost) scope
        metrics:
            memory:
            disk:
            tcp:
            docker:
            uptime:
poll-interval: 10

Setting Custom metrics

hosts:
  children:
    'localhost':
        connection:
            type: local
        # A custom metric named `custom-ls` with a command `ls $HOME/app` is defined within a host (localhost) scope
        metrics:
            custom-ls: 'ls $HOME/app'   
poll-interval: 10

Polling

polling-interval - interval in seconds between requests to host (value must be greater than or equal to 5 seconds)

Example

NOTE: Use a reasonable time interval between 10-30 seconds to avoid overloading server

hosts:
  children:
    'localhost':
        connection:
            type: local
        metrics:
            disk: 
# polling-interval set to 5 seconds
poll-interval: 5  

Deployment

Tagging

To create a new tag, use the make file

make upgrade version=0.x.x

This will tag a new version, push to github and trigger goreleaser
