Azure - PostgreSQL Server Opspack
Azure Database for PostgreSQL provides a managed database service for app development and deployment, allowing you to create a PostgreSQL database in minutes and scale right away. Designed for app developers, Azure PostgreSQL Server allows users to focus on application management and have assurance in its high availability and trustworthy cloud platform.
What You Can Monitor
Opsview Monitor's Azure PostgreSQL Opspack provides all the latest metrics to visualize and track by providing useful dashboards, reports and notifications. Common PostgreSQL issues such as I/O issues and connections are easy to identify with granular customizable thresholds.
|Percentage CPU||Current CPU usage of the database server.|
|Compute Limit||Number of CPU cores the database is limited to.|
|Compute Consumption Percent||The amount of the resource that has been consumed by the CPU.|
|Memory Percent||Current memory usage of the database.|
|IO Consumption Percent||The amount of I/O resources being consumed.|
|Storage Percent||The hard disk usage of the database.|
|Storage Used||The hard disk storage currently used.|
|Storage Limit||The limit of hard disk space the database has been allocated.|
|Active Connections||Number of active connections currently connected to the database.|
|Connections Failed||Number of failed connection attempts to the database.|
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 - Virtual Machines' Opspack to your Opsview Monitor system.
Step 1: Add the 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 to match the values retrieved earlier.
