Best Mainframe Monitoring Tools

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, this makes covering multiple mainframes very difficult.

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.

Here is our list of the best mainframe monitoring tools:

  1. Datadog Infrastructure Monitoring This is a cloud-based tool that provides incredible versatility, value for money, and customizability. It integrates with the rest of the Datadog suite while supporting a myriad of 3rd party add-ons and extensions. It has an excellent UI, alerts system, and root-cause detection capabilities. It’ll forecast issues long before they ever impede the performance of your mainframe.
  2. ManageEngine OpManager Plus 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.
  3. BMC Automated Mainframe Intelligence An excellent SaaS package made specifically for IBM z series mainframes.
  4. Z-RAYS A cloud-based platform with excellent historical analysis functionalities
  5. ASG TMON for z/OS A highly customizable tool installed directly onto IBM series z mainframes.

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.

Our Criteria

There are a lot of mainframe monitoring tools on the market, each of them promising dozens of different features. However, some features carry a little more weight than others, and we’re not able to spend years with each tool to test it out in all of its use cases. Because of this, we’ve assembled a list of main criteria that guide our placement decisions:

  • The tool should have packages that let you monitor multiple mainframes, aggregating their performance reports together.
  • The ability to monitor how your mainframe uses up physical resources.
  • Whether or not the tool is capable of creating demand forecasts.
  • Tools with a free trial or demo have an edge because you can see whether or not they’re a good fit for you before committing to a purchase.
  • How proportional the tool’s price is to its features.
  • Tools that can track the activity on resources other than mainframes are prioritized.

The Best Mainframe Monitoring Tools

1. Datadog Infrastructure Monitoring

Datadog Infrastructure Monitoring

Datadog is one of the titans of the IT monitoring page. Datadog Infrastructure Monitoring is a SaaS package monitoring all of the apps and services run on your systems. It will look deep into what resources are used by which apps running on the host. While this tool doesn’t look at the network, you can use it in conjunction with any other one of Datadog’s monitoring solutions.

One plug-in like this lets you monitor IBM z series mainframes. It interlaces the IBM z mainframe and Datadog Infrastructure monitoring, letting you look at live performance data of that mainframe alongside your other mainframes from the central console.

While this plug-in, called z/IRIS is an add-on, it lets you monitor all endpoints within your networks, such as desktops running macOS, Linux, or Windows operating systems. You can also monitor cloud platforms like Azure through Datadog’s Infrastructure Monitoring system.

The tool also boasts impressive AI-based z/OS problem detection capabilities, letting you find issues that would be difficult to catch with the human eye. It also doubles as a security monitor, alerting you in case any suspicious activity occurs.

However, z/IRIS doesn’t have a free trial, and the tool can be a bit difficult to get used to for less technical users. While both Datadog and the z/IRIS plugin are cloud-based, you’ll need to install an agent on each mainframe and a server on your network. The Datadog Infrastructure Monitor offers a 14-day free trial, while z/IRIS allows you to request a demo.

2. ManageEngine OpManager Plus

ManageEngine OpManager Plus

The ManageEngine OpManager Plus is an on-prem solution that looks over everything from your network to hosts and the services and apps running on them.

AMI uses artificial intelligence to forecast when your resources might get used up, in addition to predicting bottlenecks, as well as predicting when software or services are coming close to exhausting your mainframe’s available resources.

If AMI notices a problem like this, it will show you the issue in a color-code format, showing its urgency and severity, in addition to sending an alert. Because all of the modules within the tool are well-coordinated, the tool makes root-cause analysis extremely quick, helping you troubleshoot critical issues.

However, the BMC AMI doesn’t offer a free trial, so we’d advise making sure that it’s the perfect tool for you before purchasing.

4. IntelliMagic Vision for z/OS

IntelliMagic Vision for z/OS

IntelliMagic Vision for z/OS is another collection of tools, made to monitor IBM z series mainframes. These tools allow you to monitor your systems for issues, as well as run out updates to multiple devices at once.

Main Features:

  • A variety of deployment options.
  • AI-based forecasting and highlighting.
  • Web-based console with great graphics.
  • Lets you look at in-depth information quickly.
  • Although it’s a SaaS platform, you can get the tool as a software package if you request it.

In the dashboard, you’ll be able to see all recent events ranked by their importance. This lets you prioritize issues based on which ones are more urgent. There are also tools within the package to help you tune mainframe performance to optimal levels.

The IntelliMagic also finds changes in demands, letting you account for future resource supplies.

The IntelliMagic console has a summary screen as its counterpart. Its Change Detection view is the default panel, and it shows you how your mainframe is performing compared to the last 30 days. This helps you find drastic increases and decreases in throughput quickly. These are shown through live graphs and color-coded charts, and you can split them by source of activity if you want to take a closer look at, say, CPU usage.

However, the IntelliMagic Vision for the z/OS system can’t monitor systems outside of the mainframe, so it’s fairly narrow in its usage. The tool offers a free trial on request.

5. Z-RAYS

Z-RAYS

Z-RAYS is a cloud-based Software as a Service platform that excels at historical data analysis. It collects its data exclusively from IBM z series mainframes and shows you all of its performance metrics live in its console window.

Main Features:

  • Excellent data consolidation capabilities.
  • Easy to set up and use.
  • A variety of different activity views is available.
  • Extracting data from the tool is a breeze.

Although Z-RAYS is a cloud-based system, it needs a few agents to be installed on the mainframe it needs to monitor. Those agents upload data from your mainframe to the Z-RAYS server in the cloud, and that’s where the tool processes it. Not only does Z-RAYS package this data to better display it, but it’ll also look at resource utilization metrics, and send you an alert if thresholds are met. It also sends alerts when you’re at or near full capacity.

The alerts don’t need to only go off when a threshold is met. You can configure Z-RAYS to use machine learning to detect unusual activity. This is the mode you should keep on when you’re looking to ensure mainframe security more than performance.

Exporting data from Z-RAYS is also incredibly simple. You can extract data from it and then analyze it in a variety of tools like Elastic Stack. You can also filter through all of the data in Z-RAYS showing info about a specific database or package running on your mainframe.

The tool is also quite customizable and easy to set up. You can set up the screens of its web-based console window so that they display the metrics you’re most interested in, rather than relying on what it does out of the box. It also has a variety of pre-set templates to get you up and running quicker.

However, the tool has no free trial, and it’s missing some versatility its competition boasts. Although there isn’t a free trial, you can try the tool by requesting a demo.

5. ASG TMON for z/OS

ASG TMON for z/OS

ASG TMON for z/OS is a mainframe performance monitoring tool with system management capabilities. The tool is installed directly onto an IBM z series mainframe, and can be networked from there, or set up to feed data to an external data analytics utility.

Main Features:

  • Data is easily extracted from the tool.
  • Live monitoring and analysis features.
  • Has multiple data display tools available.
  • Very customizable.

While the AGS TMON for z/OS needs to be run on each mainframe individually, you can use an XCF, or Cross System Coupling Facility to look at data from multiple mainframes from one device. However, this view isn’t the prettiest since it relies on graphics from the OS. Because of this, most users elect to export their data through the Export and Data Extraction utilities to be able to look at their data from a more intuitive perspective.

These extractions can be run through the tool multiple times to consolidate performance metrics from a variety of mainframes. One of the best data analysis tools for it is called ASG-NaviGate, and it lets you conduct capacity planning based on the data.

The tool is excellent at detecting anomalies and conducting root-cause analysis. Whenever a problem crops up, it’ll attempt to find what caused it.  NaviGate, however, requires the data extracted from ASG TMON for z/OS to provide an HTML-based GUI for the tool. You can also use NaviPlex, which runs on Windows systems, and lets you format, sort, and display data in multiple different formats.

However, the tool requires data from it to be stored and moved around between different devices, meaning there are often simpler choices. The tool doesn’t offer a free trial, but a demo can be requested.

Closing Words

As always, which one of these tools is ideal for your business will depend on your needs. Your number 1 pick might be our number 5, however, we’ve tried to ensure that the first three entries have the right mix of versatility and power that you can’t go wrong with picking any of them.

The first step in deciding what Mainframe monitoring tool to go for will be looking for which tools support your mainframe’s vendor.
