Event Management: Reactive, Proactive or Predictive?

Three questions to ask during a post-mortem review

Can event management help foster a curiosity for innovative possibilities to make application performance better? Blue-sky thinkers may not want to deal with the myriad of details on how to manage the events being generated operationally, but could learn something from this exercise.

Consider the major system failures in your organization over the last 12 to 18 months. What if you had a system or process in place to capture those failures and mitigate them from a proactive standpoint preventing them from reoccurring? How much better off would you be if you could avoid the proverbial “Groundhog Day” with system outages?

The argument that system monitoring is just a nice to have, and not really a core requirement for operational readiness, dissipates quickly when a critical application goes down with no warning.

Starting with the Event management and Incident management processes may seem like a reactive approach when implementing an Application Performance Management (APM) solution, but is it really? If “Rome is burning”, wouldn’t the most prudent action be to extinguish the fire, then come up with a proactive approach for prevention? Managing the operational noise can calm the environment allowing you to focus on APM strategy more effectively.

Asking the right questions during a post-mortem review will help generate dialog, outlining options for alerting and prevention. This will direct your thinking towards a new horizon of continual improvement that will help galvanize proactive monitoring as an operational requirement.

Event Management

Here are three questions that build on each other as you work to mature your solution:

  1. Did we alert on it when it went down, or did the user community call us?

  2. Can we get a proactive alert on it before it goes down, (e.g. dual power supply failure in server)?

  3. Can we trend on the event creating a predictive alert before it is escalated, (e.g. disk space utilization triggers a [email protected]%, [email protected]%, [email protected]%)?

The preceding questions are directly related to the following categories respectively: Reactive, Proactive, and Predictive.

Reactive – Alerts that Occur at Failure
Multiple events can occur before a system failure; eventually an alert will come in notifying you that an application is down. This will come from either the users calling the Service Desk to report an issue or it will be system generated corresponding with an application failure.

Proactive – Alerts that Occur Before Failure
These alerts will most likely come from proactive monitoring to tell you there are component failures that need attention but have not yet affected overall application availability, (e.g. dual power supply failure in server).

Predictive – Alerts that Trend on a Possible Failure
These alerts are usually set up in parallel with trending reports that will help predict subtle changes in the environment, (e.g. trending on memory usage or disk utilization before running out of resources).

Conclusion
Once you build awareness in the organization that you have a bird’s eye view of the technical landscape and have the ability to monitor the ecosystem of each application (as an ecologist), people become more meticulous when introducing new elements into the environment. They know that you are watching, taking samples, and trending on the overall health and stability leaving you free to focus on the strategic side of APM without distraction.

The explosion of new web/cloud/IoT-based applications and the data they generate are transforming our world right before our eyes. In this rush to adopt these new technologies, organizations are often ignoring fundamental questions concerning who owns the data and failing to ask for permission to conduct invasive surveillance of their customers. Organizations that are not transparent about how their systems gather data telemetry without offering shared data ownership risk product rejection, regu...
Containers and Kubernetes allow for code portability across on-premise VMs, bare metal, or multiple cloud provider environments. Yet, despite this portability promise, developers may include configuration and application definitions that constrain or even eliminate application portability. In this session we'll describe best practices for "configuration as code" in a Kubernetes environment. We will demonstrate how a properly constructed containerized app can be deployed to both Amazon and Azure ...
DevOps is often described as a combination of technology and culture. Without both, DevOps isn't complete. However, applying the culture to outdated technology is a recipe for disaster; as response times grow and connections between teams are delayed by technology, the culture will die. A Nutanix Enterprise Cloud has many benefits that provide the needed base for a true DevOps paradigm. In their Day 3 Keynote at 20th Cloud Expo, Chris Brown, a Solutions Marketing Manager at Nutanix, and Mark Lav...
The now mainstream platform changes stemming from the first Internet boom brought many changes but didn’t really change the basic relationship between servers and the applications running on them. In fact, that was sort of the point. In his session at 18th Cloud Expo, Gordon Haff, senior cloud strategy marketing and evangelism manager at Red Hat, will discuss how today’s workloads require a new model and a new platform for development and execution. The platform must handle a wide range of rec...
The Internet of Things is clearly many things: data collection and analytics, wearables, Smart Grids and Smart Cities, the Industrial Internet, and more. Cool platforms like Arduino, Raspberry Pi, Intel's Galileo and Edison, and a diverse world of sensors are making the IoT a great toy box for developers in all these areas. In this Power Panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, panelists discussed what things are the most important, which will have the most profound e...
If your cloud deployment is on AWS with predictable workloads, Reserved Instances (RIs) can provide your business substantial savings compared to pay-as-you-go, on-demand services alone. Continuous monitoring of cloud usage and active management of Elastic Compute Cloud (EC2), Relational Database Service (RDS) and ElastiCache through RIs will optimize performance. Learn how you can purchase and apply the right Reserved Instances for optimum utilization and increased ROI.
TCP (Transmission Control Protocol) is a common and reliable transmission protocol on the Internet. TCP was introduced in the 70s by Stanford University for US Defense to establish connectivity between distributed systems to maintain a backup of defense information. At the time, TCP was introduced to communicate amongst a selected set of devices for a smaller dataset over shorter distances. As the Internet evolved, however, the number of applications and users, and the types of data accessed and...
Consumer-driven contracts are an essential part of a mature microservice testing portfolio enabling independent service deployments. In this presentation we'll provide an overview of the tools, patterns and pain points we've seen when implementing contract testing in large development organizations.
In his session at 19th Cloud Expo, Claude Remillard, Principal Program Manager in Developer Division at Microsoft, contrasted how his team used config as code and immutable patterns for continuous delivery of microservices and apps to the cloud. He showed how the immutable patterns helps developers do away with most of the complexity of config as code-enabling scenarios such as rollback, zero downtime upgrades with far greater simplicity. He also demoed building immutable pipelines in the cloud ...
You have great SaaS business app ideas. You want to turn your idea quickly into a functional and engaging proof of concept.
