- medium.com: Monitoring Microservices - Part 1: Observability | Anderson Carvalho Achieving observability with probes, logs, metrics, and traces. The Observability Pyramid comprises Probes, Logs, Metrics, and Traces:
- Probes: Probes are often exposed as endpoints and used by external agents like load balancers, container orchestrators, application servers, and sysadmins before deciding what to do next. The most common probes are starting, ready, and live. The startup probe is on during the component bootstrap phase. The liveness probe is on from the time the component starts until it stops running. The readiness probe is on during the period where the component is ready/open to receive requests or process workload.
- Logs: Logs are messages produced during the component execution that capture a piece of relevant information. Usually, we classify log messages into all, debug, info, warn, error, and fatal. Logs can produce a huge amount of data and contain sensitive information. A good practice is to apply different log levels depending on the environment.
- Log Aggregation: Each component generates one or more log files. Since distributed systems are composed of multiples components, it’s a daunting and miserable task to dig into a bunch of log files during troubleshooting. Thus, log aggregation is highly recommended for Microservices.
- Metrics: Metrics give us the visibility of good and bad events that happen inside of an application. Metrics help us to distinguish between normal and abnormal application behavior. Usually, we collect, count, summarize and compare events related to rate, errors, duration, and saturation to produce metrics.
- Traces: Traces record the flow of data between different components and execution details of each one along the way. By tracing we can discover the relationships, dependencies between components, identify bottlenecks, comprehend the data flow, and the time span on each component.

Custom Grafana Dashboard for OpenShift 3.11
By default OpenShift 3.11 Grafana is a read-only instance. Many organizations may want to add new custom dashboards. This custom grafana will interact with existing Prometheus and will also add all out-of-the-box dashboards plus few more interesting dashboards which may require from day to day operation. Custom Grafana pod uses OpenShift oAuth to authenticate users and assigns “Admin” role to all users so that users can create their own dashboards for additional monitoring.
Getting Started with Custom Dashboarding on OpenShift using Grafana. This repository contains scaffolding and automation for developing a custom dashboarding strategy on OpenShift using the OpenShift Monitoring stac
Capacity Management Grafana Dashboard
This repo adds a capacity management Grafana dashboard. The intent of this dashboard is to answer a single question: Do I need a new node? . We believe this is the most important question when setting up a capacity management process. We are aware that this is not the only question a capacity management process may need to be able to answer. Thus, this should be considered as the starting point for organizations to build their capacity management process.
Software Delivery Metrics Grafana Dashboard
This repo contains tooling to help organizations measure Software Delivery and Value Stream metrics.
Prometheus for OpenShift 3.11
This repo contains example components for running either an operational Prometheus setup for your OpenShift cluster, or deploying a standalone secured Prometheus instance for configurating yourself.
OpenShift 4
OpenShift Container Platform includes a pre-configured, pre-installed, and self-updating monitoring stack that is based on the Prometheus open source project and its wider eco-system. It provides monitoring of cluster components and includes a set of alerts to immediately notify the cluster administrator about any occurring problems and a set of Grafana dashboards. The cluster monitoring stack is only supported for monitoring OpenShift Container Platform clusters.
OpenShift Cluster Monitoring components cannot be extended since they are read only.
Monitor your own services (technology preview): The existing monitoring stack can be extended so you can configure monitoring for your own Services.

medium: Which Elasticsearch Provider is Right For You? 🌟 In this post, we’ll explain the core differences between Elastic Cloud, AWS ESS, and self-hosted, so that you can make an informed decision.
AWS ESS Elastic Cloud Self-hosted Operational Burden Medium. Requires intimate knowledge of other AWS services to go beyond defaults. Low. Backups, version upgrades, etc. are automated. High. You need to provision, configure and maintain the cluster(s) yourself. Cost Medium. Over 50% premium on underlying infrastructure cost. High. Up to 3x the cost of underlying infrastructure. Low. Only pay for the underlying infrastructure. Optionally can purchase x-pack license for additional features and support. Configurability Low. No support for custom plugins. Several configuration parameters are not available. Medium. Does support custom plugins and all parameters are available. Lack of direct node ssh access. High. Full node-level acess. Monitoring Mediocre. Kibana monitoring is not available. Cloudwatch is often inadequate for Elasticsearch monitoring. Good. Kibana monitoring available and pre-installed. Depends. It is up to you to implement an adequate monitoring system, but you have access to kibana monitoring. Future-proof Medium. Oftern lags several minor versions behind the latest Elasticsearch version. Some features are not available at all. High. Same day Elasticsearch version parity. All features are available. High. Up to you to upgrade as needed, but in theory the same Elastic Cloud. -

- trstringer.com: Observability with OpenTelemetry Part 1 - Introduction
- medium.com/apache-apisix: End-to-end tracing with OpenTelemetry
- A major component of the OpenTelemetry specification is distributed tracing.
- Tracing is about analyzing, recording, and describing transactions.
- Distributed Tracing: Troubleshooting requests between interconnected cloud-based microservices can’t always be done with logs and metrics alone. This is where distributed tracing comes into play: It provides developers with a detailed view of individual requests as they “hop” through a system of microservices. With distributed tracing you can:
- Trace the path of a request as it travels across a complex system.
- Discover the latency of the components along that path.
- Know which component in the path is creating a bottleneck or failure.
- Performance: Latency is a very important metric in microservices. Latency problems in one service will impact the overall request latency when chaining calls to different microservices. Every call to a microservice should record a trace, which is basically a record of how much time it took to respond. It’s possible to add more details to the function level, including the action, the result, and the pass to the next service. The hard part is triaging all traces in a request from a client. Usually, a trace ID header has to be sent in every request. If there isn’t one, the logging library creates it and it will represent the first trace in a request. Adding traces with OpenCensus is simply a matter of including the libraries and registering an exporter.
- Monitoring in a Microservices/Kubernetes World: In distributed system architectures like microservices, having visibility from different perspectives will be critical at troubleshooting time. Many things could happen in a request when there are many parts constantly interacting at the same time. The most common method is to write logs to the stdout and stderr streams.
- For example, a latency problem in the system could exist because a microservice is not responding correctly. Maybe Kubernetes is restarting the pod too frequently, or perhaps the cluster is out of capacity and can’t schedule any more pods. But for this reason, tools like Istio exist; by injecting a container in every pod, you can get a pretty good baseline of telemetry. Additionally, when you add instrumentation with libraries like OpenCensus, you can deeply understand what’s happening with and within each service.
- All this information will need a storage location, and as a good practice, you might want to have it a centralized location to provide access to anyone in the team — not just for the operations team.

Red Hat AMQ Broker (ActiveMQ Artemis) | Prometheus plugin for AMQ Broker To monitor the health and performance of your broker instances, you can use the Prometheus plugin for AMQ Broker to monitor and store broker runtime metrics. Prometheus is software built for monitoring large, scalable systems and storing historical runtime data over an extended time period. The AMQ Broker Prometheus plugin exports the broker runtime metrics to Prometheus format, enabling you to use Prometheus itself to visualize and run queries on the data. You can also use a graphical tool, such as Grafana, to configure more advanced visualizations and dashboards for the metrics that the Prometheus plugin collects. The metrics that the plugin exports to Prometheus format are listed below. A description of each metric is exported along with the metric itself. |

Red Hat AMQ Streams (Kafka) | JMX, OpenTracing+Jaeger ZooKeeper, the Kafka broker, Kafka Connect, and the Kafka clients all expose management information using Java Management Extensions (JMX). Most management information is in the form of metrics that are useful for monitoring the condition and performance of your Kafka cluster. Like other Java applications, Kafka provides this management information through managed beans or MBeans. JMX works at the level of the JVM (Java Virtual Machine). To obtain management information, external tools can connect to the JVM that is running ZooKeeper, the Kafka broker, and so on. By default, only tools on the same machine and running as the same user as the JVM are able to connect. Distributed Tracing with Jaeger: - Kafka Producers, Kafka Consumers, and Kafka Streams applications (referred to as Kafka clients) - MirrorMaker and Kafka Connect - Kafka Bridge |

Red Hat AMQ Streams Operator | AMQ Streams Operator (Prometheus & Jaeger), strimzi, jmxtrans How to monitor AMQ Streams Kafka, Zookeeper and Kafka Connect clusters using Prometheus to provide monitoring data for example Grafana dashboards. Support for distributed tracing in AMQ Streams, using Jaeger: - You instrument Kafka Producer, Consumer, and Streams API applications for distributed tracing using an OpenTracing client library. This involves adding instrumentation code to these clients, which monitors the execution of individual transactions in order to generate trace data. - Distributed tracing support is built in to the Kafka Connect, MirrorMaker, and Kafka Bridge components of AMQ Streams. To configure these components for distributed tracing, you configure and update the relevant custom resources. |

Red Hat AMQ Broker Operator | Prometheus (recommended) or Jolokia REST to JMX To monitor runtime data for brokers in your deployment, use one of these approaches: - Section 9.1, “Monitoring broker runtime data using Prometheus” - Section 9.2, “Monitoring broker runtime data using JMX” In general, using Prometheus is the recommended approach. However, you might choose to use the Jolokia REST interface to JMX if a metric that you need to monitor is not exported by the Prometheus plugin. For more information about the broker runtime metrics that the Prometheus plugin exports, see Section 9.1.1, “Overview of Prometheus metrics” |

Distributed tracing is like IPv6. The entire premise reveals itself when critical usage is achieved. Hence, there are few organizations that has resources to do the hard work of retrofitting it into their existing systems. For “green field” companies, it’s different.

One of the biggest frictions of the container ecosystem to me is the fact that I still have to deal with the node. Either directly or indirectly, managed or unmanaged, visible to me or not. And it sucks.

We want a stack debuggable all the way down to the bare metal and we want a stack that encapsulates all the complexity. We don't know what we want and all compute ended up being leaky abstractions.
— Jaana Dogan ヤナ ドガン (@rakyll) September 9, 2021
As someone who is working on monitoring and performance, my job is about leaking into abstractions. Whatever abstraction layer I am targeting, I often engage with all to cover everything down to bare metal.

If your observability strategy only relies on your service mesh, you are in the early stages of putting together a strategy. And you must have a very reliable service mesh.
— Jaana Dogan ヤナ ドガン (@rakyll) September 30, 2021
This. I work with tens of companies & they sometimes want to hire me to "fix their observability". You can't throw some tools or a single person to this problem. Observability is like security, it's a vertical. You have to embed it to your eng culture. https://t.co/poFsLhsxq9
