Vigilate

This is the source code for the second project in the Udemy course Working with Websockets in Go (Golang).

A dead simple monitoring service, intended to replace things like Nagios.

Build

Build in the normal way on Mac/Linux:

go build -o vigilate cmd/web/*.go

Or on Windows:

go build -o vigilate.exe cmd/web/.

Or for a particular platform:

env GOOS=linux GOARCH=amd64 go build -o vigilate cmd/web/*.go

Requirements

Vigilate requires:

• Postgres 11 or later (db is set up as a repository, so other databases are possible)
• An account with Pusher, or a Pusher alternative (like ipê)

Run

First, make sure ipê is running (if you're using ipê):

On Mac/Linux

cd ipe
./ipe 

On Windows

cd ipe
ipe.exe

Run with flags:

./vigilate \
-dbuser='tcs' \
-pusherHost='localhost' \
-pusherPort='4001' \
-pusherKey='123abc' \
-pusherSecret='abc123' \
-pusherApp="1" \
-pusherSecure=false
