Monitoring

Monitor your container using Grafana and Prmoetheus

In this article, we will be setting up a dashboard to monitor the watchtower, which are deployed as a container image.

cAdvisor:

cAdvisor, or Container Advisor, is an open-source tool tailored for monitoring and analyzing the performance of Docker containers and other containerization platforms. It operates as a live daemon, collecting and exporting information about running containers.

Prometheus:

Prometheus is a free and open-source tool that monitors your software systems, collecting essential data about applications and services. It provides alerts for prompt issue detection and resolution.

Grafana:

Data visualization tool that helps you to turn complex data into easy-to-understand charts and graphs. It connects to various data sources, like databases or monitoring systems, and allows you to create interactive dashboards.

Pre-requisites

For the monitoring dashboard to function as expected, make sure you have the following setup

• Docker

• Docker compose plugin

• Watchtower running as a container (any release)

Getting Started:

First, create a workspace to organise the configuration

mkdir container_monitoring 
cd container_monitoring

Now, download the configutation files, we have this hosted on github.

wget https://raw.githubusercontent.com/kaleidoscope-blockchain/config/main/monitoring_files.tar

Unarchive the files downloaded,

tar -xvf monitoring_files.tar

Finally starting up the dashboard, this is done with

docker compose up -d

Note: you can pass the option -d as exemplified in above command, to run in detached mode

The dashboard can be accessed at your url http://localhost:3000

username: admin 
password: admin

And to stop the dashboard, in the same directory

docker compose down
