Tips from the Team
By engineers, for engineers
At Papertrail we are software engineers who are passionate about programming, debugging, logging and pretty much everything about building and running applications. We enjoy keeping our coding skills sharp and playing with new technologies. Below are some of things we have picked up along the way.

New to Microservices: What You Should Know When You Set Up Logging
Let’s paint a picture. You’re a developer working on a system broken down into multiple services. These services do their one thing well and all communicate. However, it’s 3 a.m., and you get a call from your boss telling you something’s wrong. People can’t complete the tasks they’re supposed to complete, and there are errors on the webpages they’re using. You’re the first responder and need to figure out what’s going on.
Syslog Event Management for Easy Cron Job Troubleshooting
A good application usually has some sort of logging to provide clues when something goes wrong. When it doesn’t, I have to spend time making sure I can get some basic information logged when an issue occurs. In those cases, I used to write files in /var/log for every application or scheduled task. But I came to a point where there were too many files to review when I had to troubleshoot. To simplify troubleshooting, I decided to change my approach to an easier and more convenient system. This post describes what I came up with.
Tips for Aggregating and Analyzing PowerShell Logs
As you automate tasks with PowerShell, those tasks start to become more complex. As a result, logs become larger. Take a look at this huge log that was output from executing commands in PowerShell:
How to Aggregate Logs From Apps in Local Kubernetes Clusters
Local Kubernetes clusters are great for both developers and system engineers. When developing applications, programmers can use local clusters to make sure their application can be easily and correctly deployed without the need for configuring real infrastructure. System engineers can use them for testing, creating proofs of concept (POCs), or learning and trying new tools.
Best Practices for Centralized Logging in Microservices Architecture
Microservice architectures bring significant benefits to software teams. Microservices allow a team to scale individual parts of their application independently. They provide huge benefits in resilience, too. An application with a memory leak in a troublesome spot is a big problem for a monolithic architecture. One bug takes down the whole system and leads to extended outages. With a microservice architecture, a memory leak only takes down one part of the swarm. But there are downsides to the microservice approach. For starters, microservices complicate deployment plans. While you can solve some of those complications with orchestration tools, it’s another layer of technology in your stack.
How to Tail, Search, and Filter Linux Logs
Regardless of what language you code in or what type of apps you’re working on, you’re going to end up reading log files. They’re your window into what’s happening inside your code or the server you’re talking to. Linux log management is one of the skills setting an experienced developer apart from the rest.
Windows Event Log Filtering Techniques
Logs are a ubiquitous component of IT. They come in all shapes and sizes from a huge variety of sources and possible destinations. But at the end of the day, all types of logging serve a fundamental role in a technological infrastructure: they allow a system to record information about its behavior to a persistent medium. People can then look at this information and reconstruct what happened so they can detect and fix whatever issues they might find.
Best Tips for Monitoring and Filtering Your Web Server Logs
Server logs are important and can never be left out of web development. There’s no such thing as a perfect website—even one owned by a big tech company is likely to have errors in production. Using web server logs, you can easily know where the problem is coming from and solve it on time. Logs are automatically created by the server and consist of files containing information such as errors, requests made to the server, and other information worth looking at.
Intelligent Alerts for Log Monitoring: Filter Out the Noise
Creating alerts to spot problems before your users do is simple. However, when you receive too many alerts, you might end up ignoring critical problems.
Tips for Logging Apps on DigitalOcean
As a developer, you’ll always face challenges with your applications. Some of these challenges arise from the server after deploying code. It can sometimes be difficult to know what the problem is, especially if the app is running as expected in your development environment. This is something no one can escape. These errors are bound to happen to anyone, regardless of their level of experience as a software engineer or developer.
