<h2>Why not use one of the existing monitoring tools?</h2>
<p>
There are many tools out there that do monitoring in one way or the other. Here are a few:

They bring everything you need, a tool to collect logs or metrics, a database, a UI with dashboards and alerting.

The OSS community likes to break them down into separate tools.
For example the <a href="https://www.elastic.co/products/elastic-stack" target="_blank" rel="nofollow" class="external-link">ELK</a>-stack
consists of <a href="https://www.elastic.co/products/elasticsearch" target="_blank" rel="nofollow" class="external-link">Elasticsearch</a>
as database, and <a href="https://www.elastic.co/products/kibana" target="_blank" rel="nofollow" class="external-link">Kibana</a>
as the UI. It is usually combined with <a href="https://www.elastic.co/products/logstash" target="_blank" rel="nofollow" class="external-link">Logstash</a>
for logfile collection.<br/>
Another popular UI is <a href="https://grafana.com/" target="_blank" rel="nofollow" class="external-link">Grafana</a>

and many more. None of them provides the visualizations we had in mind. We wanted to plot each value of the time series data individually, so that we can identify the
response times of a single request. But tools like Splunk, Kibana, Chronograf or Grafana only plot aggregated data (average, min/max, percentiles).
