Enhance your metrics and alerting capabilities using a top-tier open-source monitoring tool. Prometheus inherently organizes all data as time series, which consist of sequences of timestamped values associated with the same metric and a specific set of labeled dimensions. In addition to the stored time series, Prometheus has the capability to create temporary derived time series based on query outcomes. The tool features a powerful query language known as PromQL (Prometheus Query Language), allowing users to select and aggregate time series data in real time. The output from an expression can be displayed as a graph, viewed in tabular format through Prometheus’s expression browser, or accessed by external systems through the HTTP API. Configuration of Prometheus is achieved through a combination of command-line flags and a configuration file, where the flags are used to set immutable system parameters like storage locations and retention limits for both disk and memory. This dual method of configuration ensures a flexible and tailored monitoring setup that can adapt to various user needs. For those interested in exploring this robust tool, further details can be found at: https://sourceforge.net/projects/prometheus.mirror/

Zeek, initially known as Bro, stands as the premier platform for monitoring network security. It is an adaptable, open-source solution driven by those dedicated to defense in the cybersecurity realm. With its origins tracing back to the 1990s, the project was initiated by Vern Paxson to gain insights into activities on university and national laboratory networks. In late 2018, to acknowledge its growth and ongoing advancements, the leadership team transitioned the name from Bro to Zeek. Unlike conventional security tools such as firewalls or intrusion prevention systems, Zeek operates passively by residing on a sensor, which can be a hardware, software, virtual, or cloud-based platform, that discreetly monitors network traffic. By analyzing the data it collects, Zeek generates concise, high-quality transaction logs, file contents, and customizable outputs that are well-suited for manual examination on storage devices or through more user-friendly applications like security information and event management (SIEM) systems. This unique approach allows for a deeper understanding of network activities without interfering with the traffic itself.
