Prometheus features and specs

  • Powerful Query Language
    Prometheus uses PromQL, a flexible and powerful query language that allows for complex and detailed queries.
  • Dimensional Data Model
    Prometheus employs a multidimensional data model with time series data identified by metric name and key-value pairs, offering great flexibility in data organization.
  • Auto-Discovery
    It supports service discovery mechanisms to automatically locate and scrape metrics from jobs, simplifying the monitoring process.
  • Alerting
    Prometheus includes built-in alerting capabilities that allow you to trigger alerts based on PromQL queries, which can be integrated with different alert management systems.
  • Scalability
    Its architecture, which uses independent single servers, scales well, allowing you to handle a large number of time series efficiently.
  • Open Source
    Prometheus is open-source and supported by a large community, offering transparency, regular updates, and numerous integrations.
  • Easy Integration
    Thanks to its compatibility with various data exporting standards and a myriad of existing exporters, integrating Prometheus into existing systems is streamlined.

Possible disadvantages of Prometheus

  • Single Points of Failure
    Prometheus instances operate independently, meaning that if a server goes down, the metrics it monitored will be unavailable unless replicated manually.
  • Storage Overhead
    Prometheus can consume significant storage, especially for high-resolution time series data, which might necessitate careful planning and management.
  • Limited Long-Term Storage
    By default, Prometheus is not designed for long-term storage of metrics and may require integration with other systems like Thanos or Cortex for this purpose.
  • Complexity for Beginners
    The sheer number of features and the complexities associated with PromQL can present a steep learning curve for newcomers.
  • Scaling Write Operations
    In high-scale environments, write operations might become a bottleneck due to the single-server nature of the Prometheus architecture.
  • Lack of Native High Availability
    While Prometheus supports running multiple instances, it does not provide built-in high availability features out-of-the-box, necessitating additional configurations.
  • No Built-in Authentication and Authorization
    Prometheus lacks native support for secure authentication and authorization, which means these features must be externally managed.

  • Show HN: Kubetail – Real-time log search for Kubernetes
    Look into https://logdy.dev . I've played around with it a little bit, but really putting some work into learning it and integrating it with OTEL traces is my next side project. Another alternative is https://openobserve.ai/ . It needs to run as a daemon to ingest logs (instead of opening a file), but it has a really nice UI. - Source: Hacker News / 13 days ago
