Observability 101: What you see is what you get

One of the most repeated pieces of advice for anyone getting started with microservices is to make sure you can see everything that’s going on inside your services. Leverage the power of observability. However, observability is a loaded term – so it’s valuable to understand what that terms mean, and what’s involved.

Observability at scale: SkyWalking it is!

SkyWalking, a top-level Apache project, is the open source APM and observability analysis platform that is solving the problems of 21st-century systems that are increasingly large, distributed, and heterogenous. It’s built for the struggles system admins face today: To identify and locate needles in a haystack of interdependent services, to get apples-to-apples metrics across polyglot apps, and to get a complete and meaningful view of performance. 

SkyWalking is a holistic platform that can observe microservices on or off a mesh, and can provide consistent monitoring with a lightweight payload.

Let’s take a look at how SkyWalking evolved to address the problem of observability at scale, and grew from a pure tracing system to a feature-rich observability platform that is now used to analyze deployments that collect tens of billions of traces per day.

Envoy's Postgres filter - Network observability

How to use Envoy’s Postgres filter for network observability

Starting with release 1.15.0 Envoy proxy supports decoding of Postgres messages for statistics purposes. This feature allows for an aggregated view of the types of Postgres transactions happening in the network. That aggregated view instantly provides a breakdown of types of Postgres operations and the number and severity of errors. Presented in a time series format allows for a clear overview of how the error rate of composition of queries changed over time.

What’s new in SkyWalking? MeterSystem and mesh monitoring in 8.0

Apache SkyWalking, the observability platform and open source application performance monitor (APM) project, today announced the general availability of its 8.0 release. Known for its powerful metrics, tracing and service mesh capabilities, SkyWalking extends its functionality with the new release by addressing user demand for metrics integration with other metrics collection systems, including Prometheus.

3X performance improvement in SkyWalking’s recent 6.1 release

Apache SkyWalking, the observability analysis and application performance monitoring (APM) tool, shattered its own performance record with its recent 6.1 release.

Designed especially for microservices, cloud native and container based architecture, SkyWalking provides distributed tracing, service mesh telemetry analysis, metric aggregation and workload visualization.

Following SkyWalking’s integration with Istio and Envoy-based Service Mesh at the end of 2018, our colleague, Hongtao Gao, set a performance baseline with his blog post SkyWalking performance in Service Mesh scenario.

Using an 8 CPU, 16GB VM test environment, SkyWalking was found to support 25K telemetry data per second, or 100K data per second in a 3-node cluster using elasticsearch as storage.

Apache SkyWalking: The New Stack features “the APM for the Heterogeneous New Stack”

Apache SkyWalking, the open source APM that Tetrate has embraced as the path to observability, was featured yestreday by the New Stack, the podcast and DevOps tech blog.

In “[SkyWalking: APM for the Heterogeneous New Stack] (https://thenewstack.io/skywalking-apm-for-the-heterogeneous-new-stack/),” Susan Hall describes SkyWalking founder Sheng Wu– who is now a Tetrate engineer– grew SkyWalking in just four years from a small project supported by a handful of volunteers into an Apache Top Level Project with hundreds of contributors, used in more than 70 companies. SkyWalking provides a “holistic platform for collection, aggregation and domain specific query system,” Wu told the New Stack. “It also is truly heterogeneous, in that it not only has agents for different systems, it also seamlessly blends service mesh in.”

Tetrate has endorsed SkyWalking as an essential tool for any company looking for a complete and meaningful map of their entire, distributed system. SkyWalking went service-mesh ready with its last, 6.0 release, and will soon support service mesh observability directly from Envoy.

New Stack highlighted the following SkyWalking features:

  • A polyglot agent-based instrumentation mechanism.
  • Tools that focus solely on distributed tracing usually don’t provide agents. Multiple language agents provided, especially with auto instrumentation supported, in Java, .NET and Nodejs.
  • Performance: Its impact CPU on the monitored application is less than 10%, even with a payload instance of just over 5k transactions per second/requests per second. This lightweight payload would support 100% trace sampling in production environments.
  • Observability for distributed systems based on traditional, agent-based and service mesh architectures, with consistent analysis and visualization.
  • Topology and dependency analysis without sampling.
  • Easy operation and maintenance achieved directly by our clusters, without reliance on big data technology

Check back soon for SkyWalking’s performance-boosting 6.1 release, expected at the end of May.
