DevOps is speeding up the application lifecycle and automated code testing. There are multiple contributors to a single software project and therefore, monitoring systems are now indispensable in every part of the DevOps toolchain.
Monitoring systems connect the departments working in silos as teams to perform and prevent broken production changes.
As the software infrastructure gets complex, there's a need to regulate more features and automation to track everything from strategy to development, integration to testing, and deployment to operations.
That's where DevOps monitoring has a role to play. The purpose of DevOps monitoring is to keep track of the entirety of the development process which includes-
- Integration and Testing
- Deployment and Operations
DevOps monitoring tools help achieve this by automating, defining, and measuring development processes throughout the pipeline. These tools give you real-time streaming, historical replay, and visualization of the state of your production apps, services, and infrastructure.
Continuous monitoring is incorporated into DevOps practices at all levels, from staging, testing, and even development. Several factors contribute to this.
- Monitoring systems provide relevant insights to businesses after proper implementation.
- As part of DevOps, monitoring is proactive, which means it detects bugs before they occur.
- Monitoring also allows better tracking of business KPIs and monitoring business metrics in production.
With its fast deployment speed and constant change, DevOps always demands top-performing tools for constant tracking, identifying, and analyzing of key metrics. The monitoring tool is a crucial step in the DevOps pipeline and needs precision in selection.
Two companies from the same domain that deploy DevOps may go for different monitoring tools.
Here's a round-up of 21 top DevOps monitoring tools that you can incorporate into your infrastructure:
Prometheus is a popular open-source system monitoring and alerting toolkit specifically built for modern application monitoring. It supports Linux server and Kubernetes monitoring and stores its metrics as time series data.
