Nagios is one of the monitoring tools. It is used for Continuous monitoring of systems, applications, services, and business processes etc in a DevOps culture. In the event of a failure, Nagios can alert technical staff of 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 affect your organization’s bottom line.
Nagios runs on a server, usually as a daemon or service. Nagios periodically runs plugins residing on the same server, they contact hosts or servers on your network or on the internet. One can view the status information using the web interface. You can also receive email or SMS notifications if something happens.
The Nagios daemon behaves like a scheduler that runs certain scripts at certain moments. It stores the results of those scripts and will run other scripts if these results change.
New Relic is a software analytics organization that attempts to derive real-time business insights from the metrics produced by the software. Some of these include user click-streams, mobile activity, end user experiences, and transactions. New Relic is SaaS based solution that uses data to help the businesses to build faster, better, and more efficient software. It provides SaaS web and mobile application for monitoring Ruby, PHP, .Net, Java, Python, Node.js, iOS, and Android applications. New Relic includes separate products for Application performance management(APM), Native mobile application performance management, Insights like Big Data analytics, Servers, and Browsers. It also provides real-time performance visibility for each component of the user production application i.e., from real user browsers, through the application code, and down to the underlying server infrastructure. The user gets the complete visibility whenever they want. As a SaaS New Relic stores and maintains the consumer’s data using its cloud storage service.
KEY FEATURES OF NEW RELIC
Application Response time
The application response time is an average of total time spent across all web transactions occurring during a selected time frame on the server-side. The application overviews the time spent in the application server is broken down into different layers such as request queuing, database, caching, application code, external calls and much more.
Application Histograms & Percentiles
Histograms and Percentiles are one of the most valuable statistical tools that show you the distribution of response times for all the user transactions. Are you looking for deeper visibility in your app or browser-side performance issues or just want to identify transaction outlines? Then the histograms and percentiles will provide you the triable data you need to quickly pinpoint and troubleshoot the problems.
Envisioning where your application is spending more time is a game changer. One cannot fix what they cannot see. Transaction tracing takes the New Relic service to the smallest transaction detail levels by collecting the data from individual HTTP requests and SQL.
Deployment Analysis, History, and Comparison
It allows the user to see before and after picture of their application performance when a change has been deployed. It quickly backs out of a change before it affects the user production.
