Every administrator is going to have a slightly different take on what’s ideal for performance monitoring. Some will want to see every last detail of resource usage and optimize all their applications to fit that need. Others are purely interested in service response and uptime. Most will want a mix of both. None of these approaches are wrong, and finding the right server monitor that fits your needs is a huge part of network optimization.
What to look for in a server monitoring tool
Performance and resource usage of the application itself
Good monitoring applications will use a minimum of resources to do their job. Even comprehensive networking suites usually place a strong focus on minimizing the amount of system and network resources they use to do their jobs. The best performance monitors will utilize just enough resources to effectively maintain close watch over the nodes they are assigned to.
Before jumping into any application, it’s good to know exactly what it needs to do in a given network. Some performance monitors are very basic, only tracking system resource usage on a server. Others are more robust and will track everything from bandwidth to system usage and perform in-depth analysis on a node-by-node basis. These systems often come in larger packages designed or intended to be used with other applications to create a full network management system. Deciding which features are needed on your network will help you narrow down which pieces of software will potentially work for you.
Presentation and ease of use
Many performance monitoring applications come with detailed graphs, charts, and statistical information to help you better understand how your network is working. The way this information is displayed plays a big part in how useful it will ultimately be. The way this information is presented and organized is also a huge factor in how easy the software is to use. Being able to quickly identify which parts of a usage report are valuable to your network will increase efficiency and help you get more out of your software.
Does the software need to be installed on one centralized control location, or on every node it is monitoring? Is it a cloud-based service? Are agents easily installed if they need to be placed on multiple nodes throughout the network? Even small networks should take this into consideration, as ease of installation on a given device can vary widely from network to network.
The best server and application performance monitoring tools
There is no “one size fits all” solution to server performance monitoring, so we’ve compiled a list that comprises a range of platforms and applications. This list includes everything from open-source, free solutions, to enterprise-grade paid implementations used by some of the biggest networking giants on the planet. Each has its own advantages and disadvantages, and the goal is to help find the right one that works for your network.
