DTail - The distributed log tail program

DTail logo image:

This article first appeared at the Mimecast Engineering Blog but I made it available here in my personal Gemini capsule too.

Original Mimecast Engineering Blog post at Medium

Running a large cloud-based service requires monitoring the state of huge numbers of machines, a task for which many standard UNIX tools were not really designed. In this post, I will describe a simple program, DTail, that Mimecast has built and released as Open-Source, which enables us to monitor log files of many servers at once without the costly overhead of a full-blown log management system.

At Mimecast, we run over 10 thousand server boxes. Most of them host multiple microservices and each of them produces log files. Even with the use of time series databases and monitoring systems, raw application logs are still an important source of information when it comes to analysing, debugging, and troubleshooting services.

Every engineer familiar with UNIX or a UNIX-like platform (e.g., Linux) is well aware of tail , a command-line program for displaying a text file content on the terminal which is also especially useful for following application or system log files with tail -f logfile.

Think of DTail as a distributed version of the tail program which is very useful when you have a distributed application running on many servers. DTail is an Open-Source, cross-platform, fairly easy to use, support and maintain log file analysis & statistics gathering tool designed for Engineers and Systems Administrators. It is programmed in Google Go.

A Mimecast Pet Project

DTail got its inspiration from public domain tools available already in this area but it is a blue sky from-scratch development which was first presented at Mimecast’s annual internal Pet Project competition (awarded with a Bronze prize). It has gained popularity since and is one of the most widely deployed DevOps tools at Mimecast (reaching nearly 10k server installations) and many engineers use it on a regular basis. The Open-Source version of DTail is available at:

https://dtail.dev

Try it out — We would love any feedback. But first, read on…

Differentiating from log management systems

Why not just use a full-blown log management system? There are various Open-Source and commercial log management solutions available on the market you could choose from (e.g. the ELK stack). Most of them store the logs in a centralised location and are fairly complex to set up and operate. Possibly they are also pretty expensive to operate if you have to buy dedicated hardware (or pay fees to your cloud provider) and have to hire support staff for it.

Open Source

Mimecast highly encourages you to have a look at DTail and submit an issue for any features you would like to see. Have you found a bug? Maybe you just have a question or comment? If you want to go a step further: We would also love to see pull requests for any features or improvements. Either way, if in doubt just contact us via the DTail GitHub page.

Dive into deep Gemini space

Check out one of the following links for more information about Gemini. For example you will find a FAQ which explains why the protocol is named "Gemini". Many Gemini capsules are dual hosted via Gemini and HTTP(S), so that people new to Gemini can sneak peak the content with a normal web browser. As a matter of fact, some people go as far as tri-hosting all their content via HTTP(S), Gemini and Gopher.

Resources

This is a list of resources I found useful. I am not an expert in all (but some) of these topics but all the resources listed here made an impact on me. I've read some of the books quite a long time ago, so there might be newer editions out there already and I might need to refresh some of the knowledge.

The list may not be exhaustive but I will be adding more in the future. I strongly believe that educating yourself further is one of the most important things you should do in order to advance. The lists are in random order and reshuffled every time (via *sort -R*) when updates are made.
