Chapter 7. Monitoring the router network

After the router network is created, you can use the following tools to monitor its status and performance:

  • Prometheus and Grafana
  • AMQ Interconnect web console

Prometheus is container-native software built for storing historical data and for monitoring large, scalable systems such as AMQ Interconnect. It gathers data over an extended time, rather than just for the currently running session.

You use Prometheus and Alertmanager to monitor and store AMQ Interconnect data so that you can use a graphical tool, such as Grafana, to visualize and run queries on the data.

7.1.1. Setting up Prometheus and Grafana

Before you can view AMQ Interconnect dashboards, you must deploy and configure Prometheus, Alertmanager, and Grafana in the OpenShift project in which AMQ Interconnect is deployed. All of the required configuration files are provided in a GitHub repository.

Procedure

  1. Clone the qdr-monitoring GitHub repository.

    This repository contains the configuration files needed to set up Prometheus and Grafana to monitor AMQ Interconnect. 

    $ git clone https://github.com/interconnectedcloud/qdr-monitoring

  2. Open the deploy-monitoring.sh script and set the NAMESPACE variable.

    Set NAMESPACE to be the name of the project into which you have deployed AMQ Interconnect. 

    #!/bin/bash

# Change the namespace to that of your project
NAMESPACE=myproject
...

  3. Run the deploy-monitoring.sh script.

    This script creates and configures the OpenShift resources needed to deploy Prometheus, Alertmanager, and Grafana in your OpenShift project. It also configures two dashboards that provide metrics for the router network. 

    $ ./deploy-monitoring.sh

  4. Create a Route for the prometheus, alertmanager, and grafana Services. 

    $ oc expose service prometheus

$ oc expose service alertmanager

$ oc expose service grafana

7.1.2. Viewing AMQ Interconnect dashboards in Grafana

After setting up Prometheus and Grafana, you can visualize the AMQ Interconnect data on the following Grafana dashboards:

Qpid Dispatch Router

Shows metrics for:

  • Deliveries ingress
  • Deliveries egress
  • Deliveries ingress route container
  • Deliveries egress route container
  • Deliveries redirected to fallback destination
  • Dropped presettled deliveries
  • Presettled deliveries
  • Auto links
  • Link routes
  • Address count
  • Connection count
  • Link count
Qpid Dispatch Router - Delayed Deliveries

Shows metrics for:

  • Cumulative delayed 10 seconds
  • Cumulative delayed 1 second
  • Rate of new delayed deliveries

Procedure

  1. In the OpenShift web console, switch to Networking Routes, and click the URL for the grafana Route.

    The Grafana Log In page appears.

  2. Enter your user name and password, and then click Log In.

    The default Grafana user name and password are both admin. After logging in for the first time, you can change the password.

  3. On the top header, click the dashboard drop-down menu, and then select the Qpid Dispatch Router or Qpid Dispatch Router - Delayed Deliveries dashboard.

You can use the AMQ Interconnect web console to monitor the status and performance of your router network. By default, when you create a router deployment, the AMQ Interconnect Operator generates the credentials to access the console and stores them in a Secret.

Procedure

  1. In OpenShift, switch to Networking Routes, and click the console Route.

    The web console opens in a new tab.

  2. Log in to the web console.

    To find the user name and password for accessing the web console, navigate to Workloads Secrets. The Secret containing the web console credentials is called <application-name>-users (for example, router-mesh-users).

    The syntax for the user name is <user>@<domain> (the domain is the OpenShift application name, which is the name of the Custom Resource that describes the router deployment). For example, guest@router-mesh.

  3. Use the web console tabs to monitor the router network.

    Overview

    Aggregated information about routers, addresses, links, connections, and logs.

    Entities

    Detailed information about each AMQP management entity for each router in the router network. Some of the attributes have charts that you can add to the Charts tab.

    Topology

    A graphical view of the router network, including routers, clients, and brokers. The topology shows how the routers are connected, and how messages are flowing through the network.

    Charts

    Graphs of the information selected on the Entities tab.

    Message Flow

    A chord diagram showing the real-time message flow by address.

    Schema

    The management schema that controls each of the routers in the router network.
