Azure Elastic Pool Monitoring

Azure - Elastic Pool Opspack

Deprecated in Opsview Cloud and Opsview Monitor 6.4
This Host template is now contained within the main Azure Opspack.

The Elastic database features of Azure SQL Database are designed to simplify data tier development and management, especially for Software as a Service (SaaS) developers, where large numbers of databases are used to support a dynamic end-customer base.

What You Can Monitor

Opsview Monitor's Azure Elastic Pool Opspack provides all the latest metrics to monitor your Elastic pools. Opsview Monitor contains important monitoring data such as eDTU Used, which can help provide useful date to further size your future elastic pools. Also, storage limits and percentages are identified to help manage your Elastic Pool environment.

Service Checks

Service Check	Description
cpu_percent	Percentage of CPU utilisation
physical_data_read_percent	Percentage of IO read utilisation
log_write_percent	Percentage of IO write utilisation
dtu_consumption_percent	Percentage of DTU utilisation
workers_percent	Percentage of maximum concurrent workers of the databases service tier limit
sessions_percent	Percentage of maximum concurrent sessions of the databases service tier limit
eDTU_limit	Elastic database throughput units limit
storage_limit	Storage limit in Bytes
eDTU_used	Number of allocated eDTUs
storage_used	Amount of storage utilisation in Bytes
xtp_storage_percent	Percentage of In-Memory OLTP Storage utilisation
storage_percent	Percentage of storage utilization

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

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

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

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

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 Monitoring Contributor and select the 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 - Elastic Pool' Opspack to your Opsview Monitor system

Step 1: Add the Host Template

Add the Cloud - Azure - Elastic Pool Host Template to your Opsview Monitor host.

For more information, refer to Opsview Knowledge Center - Adding Host Templates to Hosts.

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 to match the values retrieved earlier.

For more information, refer to Opsview Knowledge Center - Adding Variables to Hosts.
