Most businesses relying on mainframes use their operating system’s native monitoring package. While this ensures that the monitoring tool and OS are compatible and interlaced, many of them lack certain features available to dedicated mainframe monitoring tools. Furthermore, each of these is only dedicated to a single machine, which makes covering multiple mainframes very difficult.

Here is our list of the best mainframe monitoring tools:

1. ManageEngine OpManager Plus – EDITOR’S CHOICE An on-premises solution that aims to unify your monitoring efforts under 1 tool. It provides network management natively and integrates with other ManageEngine tools. Download a 30-day free trial.
2. Site24x7 – FREE TRIAL A detailed server monitoring tool that combines data from different metrics, logs, and other sources to provide insights into the performance of servers. Using this data, you can take proactive action to troubleshoot and improve performance. Start a 30-day free trial.
3. Datadog Infrastructure Monitoring This is a cloud-based tool that provides incredible versatility, value for money, and customizability.
4. BMC Automated Mainframe Intelligence An excellent SaaS package made specifically for IBM z series mainframes.
5. IntelliMagic Vision for z/OS Provides tools for IBM z series mainframe monitoring and facilitates mass updates across devices.
6. Z-RAYS A cloud-based platform with excellent historical analysis functionalities
7. ASG TMON for z/OS A highly customizable tool installed directly onto IBM series z mainframes.

Because of this, many businesses opt to go for a dedicated mainframe monitoring tool. These tools will allow you to find activity clashes, bottlenecks, and performance issues far better than a native monitoring package could. Native monitoring tools also entirely miss out on inefficiencies within network configurations.

If you’re looking to make your business more efficient and centralize device management within a single tool, you’ll need to find the right mainframe monitoring tool for you.

Common Mainframe Monitoring Issues

While mainframes provide a massive amount of processing power, if you’ve already invested in one, it’s a waste of capital to have it run at anything less than its peak performance. This means you need to keep the mainframe operational at least during business hours, with many businesses needing their mainframe around the clock. This makes scheduling updates and maintenance a matter of precision. This is where native monitoring tools fail, as they only focus on one machine, and leave you having to deal with how they all relate to each other manually.

Another common mainframe monitoring issue is the lack of demand analysis and capacity planning. You can only perform more advanced system management duties properly if you’ve got a detailed outlook of the load profile on your mainframes.

This means that for your mainframes to run at their peak performance, you need to have a full assessment of each of them, as well as their demands and maintenance cycles. Being able to finesse these factors will let you get that much more power from your mainframe.

Finally, sometimes issues can get quite complex, to the point where it would take a team weeks to discover the original cause. For this reason, many mainframe monitoring tools have root-cause analysis capabilities, to help you find out the cause of issues without spending valuable man-hours on it.
