Process Metrics on the Windows Agent By @TrevParsons | @DevOpsSummit [#DevOps]

Log data provides the most granular view into what is happening across your systems, applications, and end users

Gathering Process Metrics on the Windows Agent

As we continue to expand Logentries' powerful search and metric capabilities, we are also looking for new ways to allow our Users to send us critical data. In the newest version of the Windows Agent users can now follow process metrics and send them to Logentries. This feature enables even more insight into your application by allowing you to monitor your processes resource allocation in Logentries. Additionally, with Logentries powerful real-time alerting capabilities you will be instantly alerted when your process stops logging.

To allow for this feature, the Logentries service has added a brand new tab to the Windows Agent. In this new view you will see a list of all your current processes in your environment. To start collecting information on a given process you simply have to click the checkbox. By default, the Windows Agent sends your metrics every 15 seconds, but this can be easily modified to fit the user's preferences. You can also refresh the list of processes by pressing the Refresh button if a process that you wish to monitor is not been listed.

Once selected, the Windows Agent will begin to send these process metrics to your logentries-stats.log, which is located in the Host registered to the Windows Agent.

In your Logentries System Stats log you will now be able to see log events detailing the resource usage of any given process. Here you can monitor the CPU, Memory and IO usage of a particular process.

Now that you have these metrics available you can start taking advantage of Logentries powerful log search and analytics features to create Dashboards, which will give you actionable insights into your process resource management.

To make things interesting, I started to monitor the Internet Explorer process and then proceeded to put IE under high load by using http://peacekeeper.futuremark.com/. This resulted in some great reporting metrics; as you can see below, we can clearly identify when the CPU for this process starts to come under load and then eventually recedes.

ChatOps is an emerging topic that has led to the wide availability of integrations between group chat and various other tools/platforms. Currently, HipChat is an extremely powerful collaboration platform due to the various ChatOps integrations that are available. However, DevOps automation can involve orchestration and complex workflows. In his session at @DevOpsSummit at 20th Cloud Expo, Himanshu Chhetri, CTO at Addteq, will cover practical examples and use cases such as self-provisioning infrastructure/applications, self-remediation workflows, integrating monitoring and complimenting integrations between Atlassian tools and other top tools in the industry.
"Storpool does only block-level storage so we do one thing extremely well. The growth in data is what drives the move to software-defined technologies in general and software-defined storage," explained Boyan Ivanov, CEO and co-founder at StorPool, in this SYS-CON.tv interview at 16th Cloud Expo, held June 9-11, 2015, at the Javits Center in New York City.
Is advanced scheduling in Kubernetes achievable?Yes, however, how do you properly accommodate every real-life scenario that a Kubernetes user might encounter? How do you leverage advanced scheduling techniques to shape and describe each scenario in easy-to-use rules and configurations? In his session at @DevOpsSummit at 21st Cloud Expo, Oleg Chunikhin, CTO at Kublr, answered these questions and demonstrated techniques for implementing advanced scheduling. For example, using spot instances and cost-effective resources on AWS, coupled with the ability to deliver a minimum set of functionalities that cover the majority of needs – without configuration complexity.
As Marc Andreessen says software is eating the world. Everything is rapidly moving toward being software-defined – from our phones and cars through our washing machines to the datacenter. However, there are larger challenges when implementing software defined on a larger scale - when building software defined infrastructure. In his session at 16th Cloud Expo, Boyan Ivanov, CEO of StorPool, provided some practical insights on what, how and why when implementing "software-defined" in the datacenter.
A strange thing is happening along the way to the Internet of Things, namely far too many devices to work with and manage. It has become clear that we'll need much higher efficiency user experiences that can allow us to more easily and scalably work with the thousands of devices that will soon be in each of our lives. Enter the conversational interface revolution, combining bots we can literally talk with, gesture to, and even direct with our thoughts, with embedded artificial intelligence, which can process our conversational commands and orchestrate the outcomes we request across our personal and professional realm of connected devices.
