Azure - Elastic Pool 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.
|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|
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
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.
