Simple process monitoring in Go

Overview

Simple server monitoring in Go

go-monitor is simple server monitoring written in Go. I was on the lookout for a tool which allowed me to monitor a list of services and notify me through SMS or email. Everything I found seemed a bit too complex and so go-monitor was born.

Notifications

Driver based notifications, supports the following

• Message bird MessageBird
• Pushover

Installation/Running

Manual

1. go get github.com/rob121/go-monitor

2. Update go-monitor.yml.sample to include the configuration options desired.

3. Rename config to config.yml.

4 ./go-monitor

Linux

1. Clone the repo
2. cd install
3. sh install.sh
4. Update configuration in /etc/go-monitor
4. systemctl start gomonitor

Compatibility

I've not tested on windows, however the process checking library now supports it, if you do test on windows, please let me know.

Configuration

Config is read through a yaml file. Users can specify how often they are notified of a given service being down through the defaultttl value in the config.

By default, processes are checked every 60 seconds. This can be increased or decreased depending on the importance of services.

processes: [ "http://192.168.1.210", "go-monitor"] //list of processes to check
notificationdriver: "pushover" //driver name, match the key below
config:
   defaultttlseconds: 3600  //how long to hold the "down" state of a service, shorter means more notifications
   notifyservicereturn: true //send a notification when the service returns up?
   checkfrequencyseconds: 5 //how often to check
drivers:
   messagebird:
     token: "test_TOKEN"
     sender: "+sender-number"
     recipients: "+recipient-numbers,+one-or-many"
   pushover: 
     token: "test"
     recipient: "test"

Additions

Down the line it would be nice to have server monitoring in addition to process monitoring:

• CPU
• Disks (usage, read/write)
• Memory

This could further be extended into network monitoring. Someday.
