IT Central Station is now PeerSpot: Here's why

Nagios Core Valuable Features

We found Nagios Core a great product. Started working with Nagios Core when RHEL 5 was there & since then it is still in functioning mode and various types of hosts and services have been configured such as the IBM AIX, Linux, Microsoft Windows, Cisco Routers & Switches & certain gateway level firewalls. (Fortigate, Juniper netscreen, Checkpoint, Radware) 

As my knowledge gains, I've stated deploying additional plug-ins to increase our productivity like monitoring DATA CENTER Temperature using Cisco 3560/3560 Chassis Temperature. This was really helpful especially when your DATA CENTER doesn't have a dedicated temperature sensor mechanism. Nagios Exchange is a great source of plug-ins.

To date, total 127 Hots & 729 Services are being monitored under Nagios on an old Intel Dual Core, 4 GB RAM Desktop Computer.!!! Our future plan is to have a HA (High Availability) Setup for Nagios Core. To achieve this, we'll be using Apache Heartbeat (HA Proxy) for 2 individual Linux nodes with Common NFS Storage for Apache nodes. For backup mechanism, we would us "rsync" between NFS Node & Cloud Node over a secure "site to site' VPN connection.

Only the disadvantage of Nagios Core is it's shell based interface. Like Nagios XI, Core doesn't have an intuitive dashboard to configure everything (Hosts & Services) in GUI. Certain open source tool GUI configuration tools are also available but never used it as their -ve reviews.

We monitor both kind of checks. Active & Passive. However, Active checks mostly works well in my architecture. Also, I do provide Nagios Core training/support as per the end client need. Also, I've prepared custom Nagios Core documents for those who wants to learn & deploy. 

The biggest difference in Nagios Core & XI is, everything comes pre-built with Nagios XI, while for Nagios Core, all add-ons needs to be configured individually. So, Nagios Core requires hard coded system administrator, who understands advanced Linux commands, Editing of files, Directory permissions, Nagios Log Generation etc.

The features of Nagios Core that we find most valuable are the plugins we use, we can check the uptime and see how many servers and routers and create groups accordingly. From these groups, we can check how many servers and routers go down. 

We also like the alerting features. One of the dashboards they provide monitor total assets and how many are up and how many are down.

The most valuable features are the reports and the way it generates the report in a graphical manner. The creating availability, the ratios, the uptime, downtime, and the outages.

The most valuable feature of Nagios Core is the ability to check the availability of the server for network connectivity. Additionally, the interface is good.
