Building an Enterprise Grade OpenSource Web Analytics System – Part 7: Analytics Dashboard

This is the seventh part of a seven-part-series explaining how to build an Enterprise Grade OpenSource Web Analytics System. In this post we are building an Analytics Dashboard in Kibana for our data in Elasticsearch. In the previous post we build the connection from Kafka to Elasticsearch and Clickhouse to store the data. If you are new to this series it might help to start with the first post. We have come a long way in this series. We built everything from the client implementation with Snowplow to the processing and enrichment pipelines with Kafka and Python and stored all the data in Elasticsearch. Now it is time to make that data accessible in an appealing way to analysts and business users. The obvious solution for Elasticsearch is Kibana, which is developed by the same company and is designed to work perfectly with Elasticsearch! Webanalytics Dashboard in Kibana In Kibana, […]

Building an Enterprise Grade OpenSource Web Analytics System – Part 6: Data Storage

This is the sixth part of a seven-part-series explaining how to build an Enterprise Grade OpenSource Web Analytics System. In this post we are taking a brief look on what we can do with the data we collected and processed with Clickhouse. In the previous post we built a persisted visitor profile for our visitors with Python and Redis. If you are new to this series it might help to start with the first post. During this series we defined multiple topics within Kafka. Now we have different levels of processing and persistence available. If we want to keep any of it, we should put it in a persistent storage like a Data Lake with Hadoop or a Database. For this project, we are using Elasticsearch and dipping our toes in a database called Clickhouse for fun! Feeding Data into Elasticsearch From the previous part, we have a nice Kafka […]

Building an Enterprise Grade OpenSource Web Analytics System – Part 1: Architecture

Some time ago I wrote a litte series on how to amp up your log analytics activities. Ever since then I wanted to start another project building a fully fledged Analytics system with client side tracking and unlimited scalability out of OpenSource components. This is what this series is about, since I had some time to kill during Easter in isolation 😊 This time, we will be using a tracker on the browser or mobile app of our users instead of logfiles alone, which is called client side tracking. That will give us a lot more information about our visitors and allow for some cool new use cases. It also is similar to how tools like Adobe Analytics or Google Analytics work. The data we collect has then to be processed and stored for analysis and future use. As a client side tracker, we will be using the Snowplow tracker. […]

Building your own Web Analytics from Log Files – Part 5: Building our first Dashboard

This is the fifth part of the six-part-series “Building your own Web Analytics from Log Files”. At this part of the series we have our log files in Elasticsearch with indices like “custom-filebeat-tracking-logs-7.4.0-2020.01.03”. First thing is to set up a Kibana index pattern for this. Kibana Configuration In Kibana we go to Management -> Index Patterns -> Create index pattern. As Index pattern we use “custom-filebeat-tracking-logs-*”, which gives us all the indices with our daily index pattern. In the next step, we set the Time Filter field name to “@timestamp”. This is the timestamp that marks the point where Filebeat indexed the document. This is fine for now, we click “Create index pattern” and are done with this part! Checking our Data Now, let’s head to the Discover section in Kibana and look at our index pattern. And there it is: Our log entries show up like we wanted: This […]

Building your own Web Analytics from Log Files – Part 4: Data Collection and Processing

This is the fourth part of the six-part-series “Building your own Web Analytics from Log Files”. Legal Disclaimer: This post describes how to identify and track the users on your website using cookies, IP adresses and browser fingerprinting. The information and process described here may be subject to data privacy regulations under your legislation. It is your responsibility to comply with all regulations. Please educate yourself if things like GDPR apply to your use case (which is very likely), and act responsibly. In the last part we have built a configuration for OpenResty to generate user and session IDs and store them in browser cookies. Now we need a way to actually log and collect those IDs together with the requests our web server handles. OpenResty Configuration To be able to log our custom variables we need to announce them to Nginx. This is done right in the server-part of […]

Building your own Web Analytics from Log Files – Part 2: Architecture

This is the second part of the six-part-series “Building your own Web Analytics from Log Files”. Architecture Overview To start of this series, let’s remember what we want to achieve: We want to enable a deeper understanding of our website users by enriching and processing the log files we already collect. This article looks at the components we need for this and how to make our life as easy as possible. To achieve our goal, we need to teach our web server to identify our users, store information about the activity in the log files, ship those files to storage and make it actionable with a way of visualizing it. Because I believe in Open Source Software, we will look at our options among that category. Another requirement is to introduce as less components as possible and keep scalability in mind. Choosing our Web Server The first part of our […]

Blogging Ideas for 2020

So, 2020 is here. Happy updated-copyright-notice! While I need to republish my website because of just that, why not think about what to write in the new year? Here are some ideas of what I may spent an article on: Adobe Analytics. Obvious choice, topics may be: Starting tips, explanations and tutorials. Give some definitions and examples for people starting with Adobe Analytics, explaining Dimensions and Metrics, props vs. eVars, interfaces, etc. Use case examples. Show how to analyze the user journey in Analytics and what to consider. Integration examples. Talk about how to integrate Analytics to get the most value with some Open Source tools for Realtime and Big Data stuff or Classifications. Admin tasks. User management considerations, setting up different things. Analytics analytics. Monitoring your adoption by looking at Analytics logfiles. Expert level stuff. Get into details about how props and eVars work internally, how time spent is […]

How I contributed to Elasticsearch without writing any code

Open Source Software (OSS) is becoming more important each day. While in the early days, most software written was offered as proprietary products, today large products are available as OSS. On one hand this often includes the ability to use it for free and change it if needed. On the other hand, those projects rely on contributions by personal and corporate volunteers to maintain the software. But the process for that can be intimidating, since those big projects seem to large and professional for anyone to make a meaningful contribution. Bricking my Elasticsearch cluster I am using OSS for almost all my projects. For personal projects, I simply don’t have the resources to adopt large scale enterprise systems, and for professional projects it’s great to be able to save cost and help those projects grow. Like I’ve described before, I use Elasticsearch whenever I need to process logfiles or vastly […]
