24th Week of 2021



Python Mysql

  • Correction: Correct the syntax of the left joins.

    Instead of using ON == addresses.user_id, use ON = addresses.user_id



Elasticsearch Exporter

  • New: Introduce the prometheus elasticsearch exporter.

    The elasticsearch exporter allows monitoring Elasticsearch clusters with Prometheus.

    Explain how to install it, configure the grafana dashboards and the alerts.

  • Improvement: Add more elasticsearch alerts.

    Measure the search latency, search rate and create alerts on the garbage collector, json parser and circuit breaker errors

Operative Systems



  • New: Introduce dunst.

    Dunst is a lightweight replacement for the notification daemons provided by most desktop environments. It’s very customizable, isn’t dependent on any toolkits, and therefore fits into those window manager centric setups we all love to customize to perfection.
