Top Server Monitoring Tools for the New Year

Ben Putano Developer Tips, Tricks & Resources

DevOps teams have more on their plate than ever. As infrastructure needs grow, so does the time required to ensure that everything’s running smoothly. This makes automation crucial – especially in the server and network monitoring world. Server monitoring tools can save teams time by automating server management and providing real-time performance updates.

As budgets reset for the New Year, there is no better time to implement a new server monitoring tool (or re-evaluate your current solution). But where do you start? It can be exhausting to surf through the available vendors, let alone trying to decide which to give a trial run.

Top Server Monitoring Tools For 2018

We’ve worked hard to compile a list of tools for a range of infrastructure sizes so you don’t have to. Let’s take a look at the top 8 server monitoring tools for 2018:

  1. Nagios XI
  2. Icinga
  3. WhatsUp Gold
  4. Retrace
  5. PRTG
  6. Zabbix
  7. OpenNMS
  8. OP5

Nagios XI

Nagios is one of the oldest server monitoring tools on the market today – and for good reason. The Linux-based solution allows you to identify and resolve infrastructure bugs before they cause any harm to critical processes. Configure your Nagios account to monitor system metrics, network protocols, services, applications, servers, and network infrastructure. Nagios also allows you to monitor all system failures in real time with alerts via email or text message.

While Nagios Core is the free version, I definitely recommend shelling out for the enterprise version: Nagios XI. Aside from the cleaner and more user-friendly interface, Nagios XI provides a plethora of reporting and custom configurations.

Icinga is a free, open source monitoring tool for your servers, networks, and applications. Icinga 2 (the most current version) comes with an elegant and ultra-responsive user interface. The most prevalent features include performance monitoring, alerting, reporting, graphing, and extensibility through plugins. Icinga also allows you to export all of your data to third-party applications, including Puppet, Foreman, and Big Panda.

WhatsUp Gold

If you’ve been in IT for a while, you’re probably familiar with WhatsUp Gold by Ipswitch. WhatsUp Gold has been around for over two decades now, and while they may have lost some market share over the past years, that’s not to say they aren’t still a top option. WhatsUp Gold offers a few variations based on infrastructure size and needs and should have an option for just about any team. The application has literally hundreds of features available, including discovery, monitoring (local and remote), deep integration, and extensive scalability. WhatsUp Gold is currently only available on Windows OS systems.

If you want to maintain a healthy application, it’s no longer enough to simply monitor basic server metrics like CPU usage and whether your servers are up or down. There are several sources of performance metrics, which is why it’s useful to have a comprehensive monitoring tool.

Enter Retrace: Stackify’s all-in-one APM, errors, logs, and monitoring tool for .NET and Java developers. Retrace allows you to monitor your entire stack and gives you code-level insights into errors and performance issues. For pre-production servers, check out Prefix, Stackify’s free code profilers for your workstation.

PRTG is another familiar server monitoring tool and arguably one of the best. PRTG covers every aspect on the IT infrastructure spectrum and provides an incredibly user-friendly experience. Features include networkg, bandwidth, server, application, and virtual machine monitoring, as well as real-time custom alerts and expansive reporting. The best part about PRTG is that it is totally free up to 100 sensors (sensor is different than device), and the paid versions are still less expensive than many of the other options.

Zabbix is another completely free open-source monitoring solution for both infrastructure and networks. Zabbix strives to be the enterprise solution for the everyday man. While their website may seem a bit janky, the solution itself is well above industry average. Monitor tens of thousands of servers, virtual machines, and network devices simultaneously.

OpenNMS is a monitoring solution aimed at serving both the innovators (i.e. start-ups) and the established enterprises. They provide two separate “flavors”: Meridian and Horizon. Meridian is an offering for enterprises that requires a license to be purchased. With constant support and stable features, Meridian is terrific for those looking for long-term monitoring system. Horizon, on the other hand, is free-to-download software following the “release early, release often” model. One of the biggest benefits to OpenNMS is the dedicated and passionate community that comes with it. A constant state of peers asking and answering questions keeps everyone up to date on best practices and uniquely connected.

Focusing on medium to large enterprises across the world, OP5 is one of the most popular server and networking solutions on the market. One of the biggest selling points of OP5 is its scalability – claiming to grow fast as your business grows (and who wouldn’t love that!?). The unified dashboard on OP5 allows you to look as closely or as broadly as you need to make sure all of your infrastructure is running smoothly. Integrate your server monitoring with application and network monitoring to help keep everything in one place. Other features include event correlation, log server monitoring, SNMP monitoring, and network visualization. OP5 does run a bit more expensive than some of the other solutions mentioned, but keep in mind, you certainly get what you pay for.
