Causation and Correlation: What Difference Does It Make?
By Joseph Hoffman
Causation and Correlation: What’s the difference? Why does it matter? Does
it matter? Some vendors use time-based correlation to connect events across
multiple observed data sets, and claim there’s a connection between two
observed data sets. This type of approach is flawed and can lead to wildly
inaccurate conclusions, which itself leads to wasted time by technical teams
and high cost to the business.
In the chart below we observe the Number of Requests and the Memory
Utilization. Wow, the increase in the Number of Requests is causing memory
utilized to go up. Quick, call Engineering and get them on this right away.
We can easily see that there’s a correlation between the Number of requests
and the memory size. Based on this data it would be relatively easy to
conclude that the increase in R... (more)
Backed by the right technology and expertise, Digital Experience Centers
(DECs) offer visual platforms for dynamic collaboration between dev, prod,
and ops teams together with business stakeholders. They support an agile
DevOps culture across an entire organization. This in turn positions user
experience squarely as the top priority. They teach us how Dynatrace can
bring customer insights, visibility into new stack technologies, and detailed
management of the deployment pipeline to transform its online learning
platform, Dynatrace University. See for yourself how information in c... (more)
In this presentation, Johannes Engelke (twitter: @quablab), SAP Hybris,
Product Owner for Backend Services, gave us an overview of what his team is
doing to run and build their Hybris as a service (YaaS) microservices
platform on AWS. Their application uses many different technologies, and
due to our broadest support of cloud-native technologies, Dynatrace supports
their monitoring needs. Dynatrace has a tight relationship with SAP Hybris
and the only APM vendors with the ability to effectively monitor
microservices running on Cloud Foundry, and the apps that run on it, such as... (more)
Successful digital transformation requires visibility across silos of
technology, development, and operations. While tracking some of this
information can be relatively simple, gaining visibility into third-party
applications–“black boxes”—is a serious challenge for many
BUT the Ulta team uses Dynatrace as a lighthouse in the fog, adding
visibility and insight to performance, execution and metrics that were
previously obscured by black boxes.
Check how, with increased visibility to application performance, the Dev team
better understands previously hidden elemen... (more)
A day ahead of the official kickoff to Perform 2017, we were joined by 375+
of some of the best minds in IT for a series of (sold-out) Hands on Training
sessions. This group was exposed to leading, in-demand technologies in the
APM market and experienced our latest product updates and innovations.
Attendees choose from 13 different tracks: from ‘Shifting Left’ and
learning how to build a Continuous Integration pipeline, to developing your
own VoiceOps solution with our Davis technology.
We seamlessly pulled off 26 sessions by renting compute power for a limited
period of time via ... (more)
