loadmonitor

Description

Keep an eye your Linux box using Slack - you will get notified with a(n):

• Warning if Ram usage exceeded 75%
• Alert if Ram usage exceeded 85%
• Alert if CPU loadavg/num_cpus > 1 (loadavg also takes into account swap usage, etc)

Dependencies

• gcc
• curl

Installation

To install the app, first create a new Slack app, and enable incoming webhooks for your target channel. Then run:

sudo bash setup.sh

This will compile the project using gcc (tested using gcc version 9.2.1) and add the project as a systemd service. You will also get a prompt to test your webhook with a "Hello World!" message.

Usage

To take the app for a spin, start the service by doing:

sudo systemctl start slack_monitor

Test whether the app is working as expected:

sudo systemctl status slack_monitor

If things are working fine, you can enable the service so that it starts up on every startup:

sudo systemctl enable slack_monitor
