Nagios XI

Pros

Nagios XI provide a complete monitoring solution for any kind of server, application, web-service or network. User interface is easy to understand and simple to customize the layout or design for each user's priority. Nagios XI monitoring host fetch the quick data from nodes and GUI interact the data into the useful information. Configuration wizards simplify the setup process for new nodes monitoring. Integrated nodes trigger the notification if it needs to increase the capacity of the system. Configuration snapshot helps in saving the day in case of new check-in messed it up and you need a immediate rollback to the last working stage.

Cons

Schedule Reports are limited to enterprise but in case of Standard edition we need to setup the jobs to generate the schedule reports. Advance reporting should have some bulk server options. Monitoring of sensitive data like certificate expiry should have some simple wizards as configuring the web-service and then monitoring the certificate is a long process such need to be simplified.

Pros

I implemented a free version of the application to monitor my complex network, spreadout across multiple locations. While it took me several attempts to get it right, once installed, I was pleasanty surprised with what I saw. Having my network distributed across multiple locations, it was hard to monitor the upstate / resources of my servers and other network devices. Once I configure Nagious to my liking, I had every network device that I wanted to monitor on the consolidated map. Very simple configuration of the config files, once you get an idea of how to work them. Really great result for a free product

Cons

Being a Linux newbie, it did take me some poking around, before I got it right. You really have to understand the structure of the product and Linux OS itself to get it right. Config files were confusing at first, but once I figured them out, it was a breeze to add / remove hosts.

Pros

Nagios XI is a powerful monitoring tool for faults detection which provide the notification via push, email or SMS. Nagios XI allows us to rollback the configuration on the last working stage in case of fault detection. The new wizard is easy and provide multiple option at the time of setup. Nagios XI have an exclusive feature of bulk modification of attributes which help in to monitoring the same set on monitoring module on newly setup environment. Audit trails feature allow to scrutinize the modification or setup.

Cons

Mobile interface is newly develop and need more development, it should provide more option for audit log and add more detail for configuration rollback option. Scheduled report should be included in standard edition.

Pros

Nagios XI is an Enterprise level monitoring tool as it helps in monitoring the service, infrastructure and network. Powerful dashboard provides all the information at the one place which helps us to monitor the infrastructure. Security can be set on the muti-level users, as it allows the client to view the required components for which they are authorized. The GUI is also very user friendly. Customization wizards is also easy and layout can be configured according to the need of the infrastructure.

Cons

Master Node is configurable on LINUX platform only. So this makes it necessary to learn LINUX for team that will setup and implement it. Once the slave nodes are 80+ it makes the Nagios XI interface slow. The Mobile interface also needs more enhancements in it. Upgrading the advance version is also complex and pre planning and backups are also required for the cases.

Pros

It allows you to monitor many network devices, such as switches, routers, servers, helping to monitor network performance and track traffic on the network interface. very easy to install on a server, the interface is very intuitive, and has a variety of customization options since Nagios is an open source software which makes it easy to add custom scripts to extend the available services.

Cons

It is a bit difficult to configure, but once configured works very well, it continues to use add-ons that in some cases work perfectly but others are painful to work, the interface is a bit slow when you have many clients on the network, and the Search is very precise and does not look for possible matches.
