8 Best Mainframe Monitoring Tools

Best Mainframe Monitoring Tools

Diego Asturias

Mainframe monitoring is an entirely different ball game. Mainframes process high volumes of transactions and input/output operations in parallel and exceptionally quickly, and they usually serve mission-critical applications.

Organizations that invest in mainframes can’t afford to lose these machines’ valuable output and resources. An underutilized mainframe can turn out as a complete waste of money. So, mainframes must run at their peak performance; they need to be continuously and fully operational during business hours and, in most cases, running 24/7.

In this post, we’ll go through the eight best mainframe monitoring tools. With these tools, system admins should be able to continuously monitor the performance and health of a mainframe and its influence on the services and applications. 

Here is our list of the eight best mainframe monitoring tools:

  1. Datadog Infrastructure Monitoring A cloud-based observability solution with infrastructure monitoring, APM, logs management, and more. It integrates with z/IRIS software for expanded mainframe observability.
  2. Dynatrace Complete observability, intelligent monitoring, and automation platform capable of monitoring IBM z mainframe.
  3. AppDynamics by Cisco A leader full-stack observability platform that integrates with z/OS IBM z “APM Connect”.
  4. Pandora FMS Enterprise An all-in-one monitoring solution that uses a z/OS plugin to collect mainframe data.
  5. Broadcom’s CA Mainframe software A leader in mainframe operations management solutions, Broadcom provides SYSVIEW to monitor and manage various mainframe subsystems.
  6. Splunk Enterprise Provides organizations with observability, security, and business intelligence. It integrates with Syncsort Ironstream to monitor mainframe sources.
  7. BMC Automated Mainframe Intelligence (AMI) A leader in mainframe solutions, BMC AMI, provides automated intelligence to monitor the performance of z/OS mainframes.
  8. Instana By IBM, is an APM platform with automated, context, and actionable enterprise observability. It integrates with z/OS, db2, CISCS, and more.

6. Splunk Enterprise

Splunk Enterprise

Splunk is “the one” data platform for all your security and observability needs. The platform integrates with virtually anything, including public clouds, apps, services, on-prem data centers, third-party tools, and edge tools, and collects their logs, metrics, and traces. The Splunk collection mechanisms deliver unified security and full-stack observability to a single place.

Key Features

The Challenges of Mainframe Monitoring

Mainframe vendors usually ship their mainframes with built-in OS-native monitoring systems and onboard hardware sensors to keep track of the entire mainframe. But these onboard sensors and OS-native monitoring systems are bound to keep track of the single mainframe.

When monitoring multiple mainframes, it can be challenging and complex to keep track of every single component in all mainframes. In addition, It can also be challenging to manage and monitor services that extend beyond a mainframe and across multiple environments. Without the flexibility, IT organizations can quickly become siloed.

What to look for in a Mainframe Monitoring Tool?

To solve most of the challenges mentioned above, today’s mainframe monitoring tools come as solutions from observability or APM platforms. These platforms extend monitoring (and management) across multiple environments, from mobile devices and mainframes to multi and hybrid clouds.

Examples are observability plug-in solutions such as the z/IRIS, which integrates your mainframe’s z/OS client to an observability tool like Datadog. Integrating your mainframe to such tools allows DevOps access to valuable insights and added visibility into the mainframe systems. DevOps and IT teams will know how mainframe systems perform for all their business applications and their availability. 

Look for the following:

  • Support the traditional mainframe components A mainframe monitoring tool must be capable of integrating to IBM z/OS and monitoring its subsystems, including IBM Customer Information Control System (CICS) or DB2. For example, Datadog, Instana, Dynatrace, and AppDynamics provide fantastic integration.
  • Real-time monitoring A real-time monitor should keep track of the processor, memory, and I/O on a foundation level. Real-time monitoring may include automation to help the system watch thresholds and events and react. Real-time monitoring allows admins to diagnose and detect immediate problems but can impact the mainframe’s performance with added overhead (if misconfigured).
  • Post-processor monitoring Some mainframe monitoring tools can process and analyze large amounts of mainframe data after the fact. These monitors help keep track of trends, capacity planning, demand analytics, or data summaries.
  • Monitor applications and how they are delivered IT admins or DevOps teams need to know how their mainframe is performing for their business applications to keep up high availability. Mainframe monitoring tools can help keep track of mainframe traces (calls and services) and metrics. They can also track transactions and DB statements. Collect transaction mainframe data from vital z/OS subsystems.
  • Agent vs. agentless Running an agent on a mainframe may introduce overhead and wasted resources. So mainframe agents must be lightweight and unobtrusive. Agentless methods (such as SNMP or HTTP) can help with easier monitoring but may also introduce some overhead on the network. Dynatrace uses a lightweight OneAgent, whereas Pandora FMS does not.
