Overview

RealOpInsight allows to monitor, measure and observe end-user applications availability atop of Kubernetes®, Zabbix®, Nagios®. It features application-specific knowledges to aggregate and handle the status of low-level probes in a way that is meaningful for any targeted end-user application.

Key Features

Fully open source (GPL v3 Licence), RealOpinsight features include:

  • Monitor business values, Define & track SLA/SLO targets: Focus on the applications that underlie your business, set up application-aware notifications, measure, observe and analyze applications availability over time.
  • Federated & unified applications monitoring: RealOpInsight enables to set up unified applications monitoring views on top of applications and corporate environments that rely on many monitoring systems. Thereby breaking monitoring silos, it boosts the productivity of operations staffs while helping them solving incident with relevant priorities.
  • Relationship mapping & event correlation: Map relationships among each application components, set up application-specific policies to calculate and propagate the severity of incidents so as to meet your particular incident management needs.
  • Simple and secured integration through API: Don't waste time on complex or boring configuration tasks, RealOpInsight only requires a read-only access to the API of the monitoring data collection backends (i.e. Kubernetes API, Zabbix API...). It's released as Docker images along with Kubernetes Helm3 manifests to ease its deployment.
  • Tactical Operations Dashboards: Whether you're an operations staff or executive, RealOpInsight allows to build user-specific tactical dashboards that allow you to have a quick insight on how your applications are operating while be able to have more details in one click.

Quick Start

RealOpInsight is released as Docker images along with Kubernetes Helm3 manifests to ease its deployment.

The below sections show how to set an instance of RealOpInsight in a couple of seconds on Kubernetes or on an OCI-compliant container engine (Docker, Podman, CRI-O, etc).

Deployment on Kubernetes

Assuming you have a Linux terminal with Helm3 installed and able to access a KUBECONFIG file to deploy resources on Kubernetes, the following command shall install an instance in the monitoring namespace. The namespace must exist, it can be changed to another value.

helm upgrade \
  --namespace monitoring \
  --install realopinsight \
  helm/realopinsight/

By default the Helm manifests also deploy a ClusterIP service named realopinsiht to expose the UI on port 80 and Prometheus metrics on port 4584. The associated in-cluster URLs are the following:

  • UI: http://realopinsight.monitoring/ui.
  • Prometheus metrics: http://realopinsight.monitoring:4583/metrics.

Remote access to the UI

To get a remote access to the UI, use one of the following options:

  • Change the service type to LoadBalancer (see Helm value files);
  • Enable an Ingress access (see Helm value files);
  • Enable port-forwarding from your local machine as follows (change the namespace if different).
    kubectl port-forward \
      --namespace monitoring \
      service/realopinsight-ui 4583:80
    
    Then point your browser at the following address: http://localhost:4583/ui/.

Deployment on Docker

The following command shall pull the image and start an instance of RealOpInsight in background. The -d option can be removed to start the instance in foreground. With this command the data of the instance will be stored locally on the Docker machine at the specified path (value of option --volume, can be changed if needed).

$ docker run -d \
  --name realopinsight \
  --network host \
  --volume $HOME/.realopinsight:/opt/realopinsight \
  rchakode/realopinsight

Once the container started, it shall enable the following endpoints:

  • UI: http://localhost:4583/ui.
  • Prometheus metrics: http://localhost:4584/metrics.

Default admin credentials

The default username and password for the UI are admin and password.

For a production setup, you must change this default password as quick as possible.

Configuration and next steps

Consider the following resources to start integrating RealOpInsight with your target monitoring environment.

Contributions

Contributions in any form (feedback, code, documentation...) are welcome.

For code contributions it's required to have skills in writing code in C+11 or later.

The software also includes Qt and Wt at it core. Having fundamentals to develop software using this frameworks may be helpful, but not required.
