Automating vSAN Policy Application: Building the Dashboard 4 of 5

Series

1, 2, 3, 4, 5

Problem

• Difficulty in quickly visualizing the current state of vSAN policies across VMs
• Lack of a centralized view for identifying VMs requiring policy updates
• Challenges in presenting complex vSAN policy data in an easily digestible format
• Need for a real-time monitoring solution for vSAN policy compliance

Troubleshooting

When attempting to monitor and manage vSAN policies across an environment, several challenges arise:

1. Manual checking of individual VM policies is time-consuming and error-prone
2. Correlating policy data with VM performance metrics can be complex
3. Ensuring all relevant stakeholders have access to up-to-date policy information
4. Integrating custom metrics and groups into a cohesive visualization

Solution

Create a comprehensive dashboard in vSphere to visualize vSAN policy states and identify VMs requiring updates:

1. Dashboard Setup

# Download the pre-configured dashboard
$dashboardURL = "https://www.kablog.nl/wp-content/uploads/2024/02/Dashboard.zip
Invoke-WebRequest -Uri $dashboardURL -OutFile "vsan-policy-dashboard.zip"

Import the dashboard in Aria Operations.

2. View Configuration

The dashboard utilizes two views:

1. Custom view (needs manual creation)
2. Out-of-the-box view

Both views can be downloaded from: [view1] and [view2]

3. Dashboard Customization

After importing the dashboard, make the following adjustments:

Configuration File Renaming:

If you’ve renamed the configuration files, as explained in the initial blog of this series, ensure to re-point them in the dashboard. This is crucial for seamless integration.

Custom Group Adjustment:

Likewise, if you’ve made changes to custom groups, especially those containing “RAID” in their name, remember to re-point all relevant widgets in the dashboard.

Data Visibility:

Once everything is configured correctly, every widget on the dashboard should showcase the desired data. Note that data visibility might take up to 20 minutes in some cases.

Implementation Steps

1. Download the pre-configured dashboard and views
2. Import the dashboard and views into vSphere
3. Adjust configuration file references if you’ve renamed them
4. Update custom group references if you’ve modified the RAID groups
5. Allow up to 20 minutes for data to populate in all widgets

Integration with Automation

• The dashboard provides a visual representation of the vSAN policy states
• Use this dashboard to identify VMs requiring policy updates
• Integrate dashboard alerts or reports with your automation script to trigger policy updates

Benefits

• Provides a centralized, real-time view of vSAN policy compliance
• Enables quick identification of VMs with mismatched or suboptimal policies
• Enhances decision-making with visual correlation of policy and performance data
• Facilitates easier communication of vSAN policy states to stakeholders

In the final part of this series, we’ll recap the entire automation process and discuss best practices for maintaining your vSAN policy management system.
