What is Nagios?

Nagios is used for Continuous monitoring of systems, applications, services, business processes, etc. in a DevOps culture.

If a failure occurs, Nagios has the alerting ability to inform the technical staff about the problem, allowing them to begin remediation processes before outages affect business processes, end-users, or customers. With Nagios, you don’t have to explain why an unseen infrastructure outage affects your application’s performance in a production environment.

By using Nagios you can:

• Plan for infrastructure upgrades proactively, before outdated systems cause failures.

• Respond to issues at the first sign of a problem.

• Automatically fix problems when they are detected.

• Coordinate technical team responses.

• Ensure your organization’s SLAs are being met.

• Monitor your entire infrastructure and business processes.
