APMdigest asked experts from across the IT industry for their opinions on what IT departments should be monitoring to ensure digital performance. Part 2 covers key performance metrics like availability and response time.
Start with What You Should Be Monitoring to Ensure Digital Performance - Part 1
AVAILABILITY
To ensure digital performance, availability is one of three key performance areas I always recommend monitoring. Your applications and networks must first be available to service users and customers. Otherwise, they're useful to no one.

Monitoring the login page of an application with a synthetic transaction is an essential part of an Enterprise Monitoring strategy. Active monitoring is a good starting point to provide visibility on application availability especially when monitoring outside the Data Center. Synthetic Transactions can provide location-based availability and act as a barometer for measuring application performance.

INFRASTRUCTURE RISK
Understanding Infrastructure Risk is a key component of monitoring that most organizations miss. APM tools do a great job of tracking left-to-right performance across an application, and modern application designs ensure that no single component can cause a failure. Building an understanding of the risk inherent in the current IT infrastructure — below the application — is critical for stopping unexpected downtime and sudden capacity limits. You can do that by tracking links from between overlay and underlay networks, file systems to storage units, and hypervisor to server hardware — or you can use a unified monitoring tool do do it for you. Key buying decision — can you see the IT infrastructure risk for the specific components that your application relies on?

THROUGHPUT
To ensure digital performance, throughput is one of three key performance areas that must be included. Applications and networks must be able to provide all the relevant data that is required to fulfill a specific request. Monitoring throughput ensures you know when your systems do not deliver all of the data that was requested, and you can act on it before the complaints come in.

PAGE LOAD SPEED
Ultimately you want to be monitoring everything that impacts customer experience and conversion rates, but the most important thing is the page load speed. This drives more conversions than any other factor. And the key pages are those at the beginning of a user journey since the more time someone has invested in the process the less likely they are to abandon.

RESPONSE TIME
To ensure digital performance, response time is one of three key performance areas that must not be forgotten. Requests for specific information from users must be fulfilled with as much speed as possible. This is a common expectation of every IT system, so you should be monitoring them.

Monitor application response from user to application (last mile) and application to the data (middle mile) to not only measure is the app up but of it is working.

TRANSACTION UPTIME
A good starting point is to implement end-to-end performance monitoring with real transaction uptime to complement your APM tools.

TIME TO FIRST BYTE
Initial motivation in the user journey can be lost very quickly if for example the first time the user clicks on an advertisement or logs into an application is not performant. The appearance of performance is important; monitoring time to first byte (TTFB)can help ascertain the experience of what a user sees marching towards a minimum viable/viewable product (MVP) of the page or app before being loaded to completion. TTFB is a leading indicator on web performance to the end user and also is used by the leading search engines in factoring in page rank as the more performant pages get a higher rank.

LOG EVENTS
If it has an IP address, it sends logs, and logs must be monitored to gain detailed insight on server performance, security, error messages or underlying issues.
Clayton Dukes
CEO, LogZilla
Logs have been around since the dawn of computing, but with constantly increasing threats, logs are more important than ever. Log events are one of the key data sources SIEM (Security Information and Event Management) solutions use for threat detection.

One common infrastructure challenge arises with virtual private networks (VPNs). VPNs have long been relied upon to deliver the network connectivity and security enterprises required at a price they could afford. Organizations still routinely turn to them to provide internal and trusted third-parties with "secure" remote access to isolated networks. However, with the rise in mobile, IoT, multi- and hybrid-cloud, as well as edge computing, traditional enterprise perimeters are extending and becoming blurred ...
The configuration management database (CMDB), along with its more federated companion, the configuration management system (CMS), has been bathed in a deluge of negative opinions from all fronts — industry experts, vendors, and IT professionals. But from what recent EMA research on analytics, ITSM performance and other areas is indicating, those negative views seem to be missing out on a real undercurrent of truth — that CMDB/CMS alignments, whatever their defects, strongly skew to success in terms of overall IT progressiveness and effectiveness ...
The on-demand economy has transformed the way we move around, eat, learn, travel and connect at a massive scale. However, with disruption and big aspirations comes big, complex challenges. To take these challenges head-on, on-demand economy companies are finding new ways to deliver their services and products to an audience with ever-increasing expectations, and that's what we'll look at in this blog ...
To thrive in today's highly competitive digital business landscape, organizations must harness their "digital DNA." In other words, they need to connect all of their systems and databases — including various business applications, devices, big data and any instances of IoT and hybrid cloud environments — so they're accessible and actionable. By integrating all existing components and new technologies, organizations can gain a comprehensive, trusted view of their business functions, thereby enabling more agile deployment processes and ensuring scalable growth and relevance over the long-term ...
Advancements in technology innovation are happening so quickly, the decision of where and when to transform can be a moving target for businesses. When done well, digital transformation improves the customer experience while optimizing operational efficiency. To get there, enterprises must encourage experimentation to overcome organizational obstacles. In other words ...

It's been all over the news the last few months. After two fatal crashes, Boeing was forced to ground its 737. The doomed model is now undergoing extensive testing to get it back into service and production. Large organizations often tell stakeholders that even though all software goes through extensive testing, this type of thing “just happens.” But that is exactly the problem. While the human component of application development and testing won't go away, it can be eased and supplemented by far more efficient and automated methods to proactively determine software health and identify flaws ...
