Open Telemetry features and specs

  • Standardization
    OpenTelemetry provides a standardized set of APIs, libraries, and agents for collecting traces, metrics, and logs, helping to ensure consistency across different platforms and tools.
  • Vendor-neutrality
    OpenTelemetry is vendor-agnostic, allowing you to integrate with various backends, reducing lock-in with any specific monitoring solution.
  • Extensibility
    Its modular architecture allows developers to extend its functionalities easily, with support for custom instrumentation and exporters.
  • Community Support
    Being part of the Cloud Native Computing Foundation (CNCF), OpenTelemetry benefits from a large, active community contributing to its development and providing support.
  • Ease of Integration
    Pre-built instrumentation libraries and SDKs for multiple languages simplify the process of integrating telemetry into your applications.

Possible disadvantages of Open Telemetry

  • Complexity
    The broad scope of OpenTelemetry, which includes tracing, metrics, and logging, can make it complex to understand and configure correctly.
  • Performance Overhead
    The process of collecting and exporting telemetry data can introduce performance overhead, which needs to be managed carefully.
  • Evolving Ecosystem
    As an emerging standard, aspects of OpenTelemetry are still under active development and can change, potentially leading to frequent updates and maintenance.
  • Learning Curve
    Engineers might face a steep learning curve when adopting OpenTelemetry due to its comprehensive nature and the need to understand various components and best practices.
  • Limited Maturity of Some Components
    Some of the libraries and features may not be fully mature yet, potentially leading to bugs or incomplete implementations in certain environments or languages.

  • 10 open-source MCPs that make your AI agents smarter than your team lead
    OpenTelemetry if you’re building at serious scale. - Source: dev.to / 1 day ago
  • Working with OpenTelemetry Metrics
    Then I stumbled upon OpenTelemetry. It is a project that aims to provide a unified way to collect, process and export telemetry data. From a hundred thousand feet, it looks like they know what they are doing: standardized data definitions and protocols, semantic conventions, etc. To me, it is like a rulebook for telemetry data --something I find reassuring to rely on. - Source: dev.to / 5 days ago
  • Pomerium’s OpenTelemetry Tracing Support: Deeper Observability, Made Easy
    OpenTelemetry is an open-source observability framework that standardizes how applications collect, process, and export telemetry data such as metrics, traces, and logs. It’s the successor to OpenCensus and OpenTracing, and is now the de facto industry standard for modern observability. - Source: dev.to / 9 days ago
  • Monitoring & Observability: New Tools to Watch in 2025
    OpenTelemetry has moved from being “the future” to “the foundation.” In 2025, a new generation of tools is being built on top of OpenTelemetry, providing automated correlation between metrics, traces, and logs. - Source: dev.to / 11 days ago
  • Kubernetes and Container Portability: Navigating Multi-Cloud Flexibility
    OpenTelemetry – a collection of tools for exporting telemetry data. - Source: dev.to / about 1 month ago

  • Top 10 Prometheus Alternatives in 2024 [Includes Open-Source]
    Cortex is a horizontally scalable, highly available, multi-tenant prometheus alternative. - Source: dev.to / 7 months ago
  • Scaling Prometheus with Thanos
    There are many Projects like Thanos, M3, Cortex, and Victoriametrics. But Thanos is the most popular among these. Thanos addresses these issues with Prometheus and is the ideal solution for scaling Prometheus in environments with extensive metrics or multiple clusters where we require a global view of historical metrics. In this blog, we will explore the components of Thanos and will try to simplify its... - Source: dev.to / 10 months ago
  • Self hosted log paraer
    Now if its more metric data you are using and want to do APM, prometheus is your man https://prometheus.io/, want to make prometheus your full time job? Deploy cortex https://cortexmetrics.io/, honorable mention in the metrics space, Zabbix, https://www.zabbix.com/ I've seen use cases of zabbix going way beyond its intended use its a fantastic tool. Source: almost 2 years ago
  • Is anyone frustrated with anything about Prometheus?
    Yes, but also no. The Prometheus ecosystem already has two FOSS time-series databases that are complementary to Prometheus itself. Thanos and Mimir. Not to mention M3db, developed at Uber, and Cortex, then ancestor of Mimir. There's a bunch of others I won't mention as it would take too long. Source: almost 2 years ago
  • Centralized solution for Prometheus?
    You can use the Remote write feature to send to a centralized location. It would have to be scalable like Cortex https://cortexmetrics.io/. Source: about 2 years ago
