The CSV file format is widely used across the business and engineering world as a common file for data exchange. The basic concepts of it are fairly simple, but unlike JSON which is more standardized, you’re likely to encounter various flavors of CSV data. This lesson will prepare you to understand how to import and parse CSV using Logstash before being indexed into Elasticsearch.
One of the best things about cloud computing is how it converts technical efficiencies into cost-savings. Some of those efficiencies are just part of the tool kit, like pay-per-use Lambda jobs. Good DevOps brings a lot of savings to the cloud, as well. It can smooth out high-friction state management challenges. Sprucing up how you provision cloud services, for example, speeds up deployments. That’s where treating infrastructure the same as workflows from the rest of your codebase comes in.
All deployments are not created equal, but you'd never know it from your Slack channel notifications. In reality, some deployments you really care about, as they contain things like API changes or database migrations, and you want that information to surface. We created tags in Sleuth for this very reason. Out of the box, Sleuth matches files in your deployment with known patterns, and if any are found, tags your deployments automatically.
Once upon a time the telephone system was a trusted method of connecting people. While we now spend more time on our phones than ever, our relationship to phone calls has changed -- we’re hesitant to answer calls from unknown phone numbers, often because we think the call is a con. But what if the caller ID is spoofed/modified and made to look like a telephone number that you may trust or a number with a local area code and familiar prefix?
Hybrid cloud infrastructures run critical business resources and are subject to some of the strictest network security controls. Irrespective of the industry and resource types, these controls broadly fall into three categories. Workloads (pods) running on Kubernetes are ephemeral in nature, and IP-based controls are no longer effective. The challenge is to enforce the organizational security controls on the workloads and Kubernetes nodes themselves.
Tuesday morning you roll out of bed, turn off your alarm, tiptoe down the stairs, retrieve your paper, flip the hallway lights on, feed the dog, and start making coffee—in five minutes. Performing this series of early-morning tasks is called chunking. Certain neurons in the brain “bookend” the habit for you, signaling the routine has started (the alarm) and ended (coffee).
The community forum is a place where you can meet and chat with other Icinga users. It’s hosted by Icinga and moderated by both the Icinga team and members of the community. It’s mostly being used as a platform to ask and answer technical questions about Icinga, which is a great way to learn more about the tool stack! What does it look like? It’s a discourse platform, so it’s a collection of threads or topics which are open for anyone to leave a comment on!
Some time ago, an ex-colleague of mine at DAZN received an alert through PagerDuty. There was a spike in error rate for one of the Lambda functions his team looks after. He jumped onto the AWS console right away and confirmed that there was indeed a problem. The next logical step was to check the logs to see what the problem was. But he found nothing. And so began an hour-long ghost hunt to find clues as to what was failing and why there were no error messages.
Checkmk was created and developed by German Mr. Mathias Kettner, and since 2007 there is an open source version. In this article, we will get to know Checkmk Open Source, which contains 90% of all the code of said monitoring software, and a Check Mk alternative… But since there are several versions, let’s see them first!
