Azure - Redis Opspack

Azure Redis Cache is based on the popular open source Redis cache. It gives you access to a secure, dedicated Redis cache, managed by Microsoft and accessible from any application within Azure. Azure Redis Cache is available in a variety of tiers, (i.e. Basic, Standard, Premium), offering an expanded set of throughput and consistent low-latency data access to power fast, scalable Azure applications.

What You Can Monitor

Opsview Monitor's Azure Redis Opspack contains all of the latest service checks to monitor your Redis environment. Opsview helps keep track of performance metrics such as Cache Read, which shows the amount of data read from cache. Cache issues can directly affect server side network bandwidth limits used by this cache.

Prerequisites

The monitoring plugin for this Opspack has been tested with Python 2.7. In order for the Opspack to run, you will need to have some Python packages installed by running the pip python package tool.

If a cryptography error occurs when trying to install the Azure packages, you can run the commands which should fix the problem.

Debian and Ubuntu

sudo apt-get install build-essential libssl-dev libffi-dev python-dev python-pip

CentOS and RHEL

sudo yum install gcc libffi-devel python-devel openssl-devel python-pip

Common

When python-pip is installed, you can then run:

sudo pip install --upgrade pip==9.0.2
sudo pip install --upgrade setuptools
sudo pip install --upgrade requests
sudo pip install nagiosplugin
sudo pip install azure
sudo pip install azure-monitor

Setup Azure for Monitoring

To monitor you Azure environment, you need to configure it for monitoring

This requires Administrator access on Azure. You need to retrieve the following credentials:

  • Subscription ID
  • Tenant/Directory ID
  • Client/Application ID
  • Secret Key

Step 1: Find Subscription ID

The Subscription ID can be found in the Subscriptions section under the All services section from the Azure dashboard

Find Azure Subscription ID

Find Azure Subscription ID

Step 2 : Find the Tenant/Directory ID

The Tenant/Directory ID can be found in the Azure Active Directory under the Properties section from the Azure dashboard

Find Azure Tenant/Directory ID

Step 3: Find the Client/Application ID for your application

You need to create and register your application if you haven't already. Use the following documentation from Microsoft: Create an Azure Active Directory application

The Client/Application ID can be found in Azure Active Directory under the App registrations section from the Azure dashboard

Find Azure Client/Application ID

Step 4: Generate the Secret Key for your application

You will need to create a Secret Key for your application, once this has been created its value will be hidden so save the value during creation

To create the Secret Key, select your application from the list, select the Settings within your application and then select the Keys option

There you can create a new key by adding the description and expiration period and the value will be generated

Create Secret Key

Step 5: Provide access to the subscription you wish to monitor

Navigate to the Subscriptions section and select the Subscription you selected before

In the Subscription to be monitored, click Access Control (IAM)

Then click the Add button, select Reader and select the application

Add Subscription to Application

Add Subscription to Application

If you are running more than one subscription these steps will need to be done for each one you wish to monitor

Setup and Configuration

To configure and utilize this Opspack, you simply need to add the 'Cloud - Azure - Virtual Machines' Opspack to your Opsview Monitor system

Step 1: Add the host template

Add Host Template

Step 2: Add and configure variables required for this host

Add 'AZURE_CREDENTIALS' to the host and set the Resource Group as its variable value

Then override the Subscription ID, Client ID, Secret Key and Tenant ID

Add Variables

Step 3: Reload and the system will now be monitored
