What is Nagios?

<h3>What is Nagios?</h3> 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: <ul><li>Plan for infrastructure upgrades proactively, before outdated systems cause failures.</li></ul> <ul><li>Respond to issues at the first sign of a problem.</li></ul> <ul><li>Automatically fix problems when they are detected.</li></ul> <ul><li>Coordinate technical team responses.</li></ul> <ul><li>Ensure your organization’s SLAs are being met.</li></ul> <ul><li>Monitor your entire infrastructure and business processes.</li></ul>

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