Overview

NAGIOS CORE IS THE FOUNDATIONAL APPLICATION THAT PROVIDES THE MONITORING AND ALERTING OPTIONS THAT NAGIOS IS KNOWN FOR. ADMINISTRATION OF THE NAGIOS INTERFACE IS MAINLY ACHIEVED THROUGH THE CLI OR COMMAND LINE INTERFACE. THE NAGIOS WEB INTERFACE WHICH USES CGI AS THE BACKEND BY DEFAULT CAN BE MODIFIED TO USE A MYSQL DATABASE. THE FRONTEND OR WEB INTERFACE, CAN BE MODIFIED WITH CUSTOM OPTIONS TO PROVIDE THE LOOK AND FEEL THAT AN ORGANIZATION NEEDS. SEVERAL EXAMPLES OF FRONTENDS WOULD BE THEMES THAT ARE AVAILABLE (I.E. EXFOLIATION, VAUTOUR AND ARANA), WEB INTERFACES LIKE VSHELL, NAGIOSDIGGER, MNTOS, CHECK_MK AND MOBILE INTERFACES LIKE NAGIOS MOBILE, NAG MOBILE AND INAG. VSHELL IS THE OFFICIAL PHP INTERFACE FOR NAGIOS CORE. NAGIOS CORE BY DESIGN FEATURES AND SUPPORTS MANY DIFFERENT ADDONS THAT CAN BE USED WITH IT.

NAGIOS XI TAKES THE NAGIOS CORE AND BUILDS UPON IT TO CREATE AN ENTERPRISECLASS MONITORING AND ALERTING SOLUTION THAT IS EASIER TO SET UP AND CONFIGURE USING A PHP FRONTEND. NAGIOS XI USING EASY TO USE NETWORK WIZARDS PROVIDES INFRASTRUCTURE MONITORING OF ALL OF AN ORGANIZATION'S CRITICAL HARDWARE, APPLICATIONS, NETWORK DEVICES AND NETWORK METRICS. THE DASHBOARD FEATURE ALLOWS YOU TO VIEW THE ENTIRE INFRASTRUCTURE VISUALLY AS YOU MONITOR ALL OF THESE SERVICES AND DEVICES. YOU ALSO HAVE THE ALERTING OPTIONS WHICH COMMUNICATE TO ADMINISTRATORS WHEN SERVICES AND HOSTS HAVE PROBLEMS. THE TRENDING AND HARDWARE CAPACITY LIMITS HELP YOU CREATE PROACTIVE DECISIONS ABOUT THE NETWORK AND DEVICES ON THE NETWORK. THE GRAPHICAL INTERFACE IS EASY TO CUSTOMIZE TO FIT THE ORGANIZATION NEEDS AND BY MONITORING THE GRAPHS WILL HELP YOU PREDICT NETWORK, HARDWARE AND APPLICATION PROBLEMS.

NAGIOS FUSION PROVIDES A GUI FOR CENTRAL MANAGEMENT OF A NETWORK INFRASTRUCTURE SPREAD OVER A LARGE GEOGRAPHICAL AREA. WITH CENTRAL MANAGEMENT NAGIOS FUSION ALLOWS THE ORGANIZATION TO REVIEW THE ORGANIZATION'S ENTIRE STRUCTURE IN ONE LOCATION THROUGH ONE INTERFACE AND YET ALLOW EACH LOCATION TO MANAGE THEIR INFRASTRUCTURE INDEPENDENTLY. TACTICAL OVERVIEW SCREENS PROVIDE A SNAPSHOT OF THE MONITORED DEVICES GLOBALLY.
