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

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 the libraries and Python packages listed below installed on Opsview Master.

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:

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

To allow programmatic access for monitoring, you need to create and register an application if you haven't already done so. Use the following documentation from Microsoft: Create an Azure Active Directory application When creating the Active Directory application, you can set the Sign-on URL to any dummy value, as this value is not used.

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

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: Import the Opspack

Download the cloud-azure-virtual-machines.opspack file from the Releases section of this repository. Navigate to Host Template Settings inside Opsview Monitor and select Import Opspack in the top left corner.

Add Variables

Then click Browse and select the cloud-azure-virtual-machines.opspack file. Click Upload and then click Import when the file is uploaded. You may see a 'CONFLICT' warning message after uploading - this is because all 'Cloud - Azure' Opspacks utilize the same variable (AZURE_CREDENTIALS) for authorizing access to your resources. Just click Overwrite and the Opspack should import successfully.

Add Variables

Step 2: Add the host template

Add the host template for Cloud - Azure - Virtual Machines. Set the Primary Hostname/IP field with the name of the host in Azure, and then open the Advanced section at the bottom and change the Host Check Command type to TCP Port 80 (HTTP). If the hostname or IP cannot be resolved, Opsview Monitor may report the host as Down by default, to fix this you may need to enable a local DNS permitting resolution of the hostname to an IP address, or add the hostname and the VM's IP to the /etc/hosts file on Opsview Master. Alternatively, if the resource has no hostname or public IP, then change Host Check Command to Always assumed to be UP.

Add Host Template

Step 3: 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 4: Reload and the system will now be monitored
