Prometheus 🔥

Moving forward, let's delve into the realm of Prometheus—an open-source system designed for monitoring services and generating alerts using a time series data model. Prometheus excels in collecting data and metrics from diverse services, organizing them based on a distinctive identifier—the metric name—and a timestamp.

To understand concept in more details will go through below task.

Tasks

1. What is the Architecture of Prometheus Monitoring?

   - Introduced by SoundCloud in 2012 and presently under the stewardship of the Cloud Native Computing Foundation (CNCF), Prometheus stands as an open-source monitoring system, playing a pivotal role in supervising distributed systems.

   The architectural blueprint of the Prometheus monitoring system involves a collaborative ensemble of multiple components working seamlessly to collect and store time-series data. Operating on a pull model, Prometheus consistently fetches data from designated targets, ensuring a robust and effective monitoring process.

2. What are the Features of Prometheus?

   - Key Features:

   1. Robust Query Capability: Prometheus boasts a powerful query language, PromQL, making it easy to explore time-series data and craft comprehensive graphs and dashboards.

   2. Multi-dimensional Data Support: The system embraces multi-dimensional data using labels, providing flexibility in querying and aggregation. This feature enhances adaptability in data analysis.

   3. Automated Service Discovery: Simplifying the addition of new monitoring targets, Prometheus incorporates automated service discovery. This streamlines the overall monitoring setup process.

   4. Efficient Data Management: With time-series data retention and compaction, Prometheus ensures efficient storage and retrieval of historical data, optimizing resource utilization.

   5. Flexible Alerting System: The platform features a versatile alerting system equipped with advanced alerting rules and support for various notification channels. This flexibility enhances its adaptability in responding to diverse monitoring scenarios.

3. What are the Components of Prometheus?

   - Key Components:

   1. Prometheus Server: At the core of the architecture, the Prometheus server functions as the central hub for collecting, storing, and querying time-series data.

   2. Exporters: Acting as agents on monitored targets, exporters play a crucial role in gathering metrics data. Prometheus seamlessly integrates with a diverse array of exporters tailored for different systems and services.

   3. Alertmanager: Responsible for overseeing alerts generated by Prometheus, the Alertmanager takes charge of dispatching notifications across various channels, including email, Slack, or PagerDuty.

   4. Pushgateway: Facilitating the transmission of metrics data to Prometheus from batch jobs, scripts, or other non-service targets, the Pushgateway serves as a pivotal component, especially in scenarios involving data push mechanisms.

4. What database is used by Prometheus?

   - Prometheus utilizes a dedicated time-series database called TSDB (Time-Series Database). Tailored to handle significant write and query demands, TSDB is designed for efficient storage and retrieval of time-series data.

5. What is the default data retention period in Prometheus?

   - In Prometheus, the default data retention duration is configured to 15 days. However, users have the flexibility to tailor this timeframe according to their needs by adjusting the storage retention time within the Prometheus configuration file. When data exceeds the specified retention period, the Time-Series Database (TSDB) automatically removes it, ensuring efficient management of historical data.
