vROPS Alert Management: Preventing Duplicate Alert Notifications

In vRealize Operations (vROPs), Skyline alerts are an essential feature that helps administrators stay on top of their virtual infrastructure’s performance and health. However, there is a known issue where Skyline alerts are automatically canceled and recreated during the next adapter run, leading to duplicated alert notifications. In this blog post, we will explore the cause of this issue and provide a solution to prevent duplicate alert notifications in vROPs.

Cause of Duplicate Alert Notifications

The reason behind duplicate alert notifications is that the Skyline adapter automatically cancels existing alerts when it runs and recreates them. This behavior is intended to ensure that only the most recent alerts are displayed in the vROPs dashboard. However, this feature can cause issues when an administrator has set up custom alerts or has enabled alerts for specific events.

When an alert is canceled and recreated, it can lead to duplicated alert notifications, which can be confusing and misleading for administrators. This issue can be especially problematic in environments where multiple vROPs nodes are used, as each node may generate its own set of alerts, leading to a large number of duplicate alerts.

Solution to Prevent Duplicate Alert Notifications

To prevent duplicate alert notifications in vROPs, administrators can adjust the configuration of the Skyline adapter. By changing a specific value on each vROPs node using SSH, administrators can ensure that alerts are not automatically canceled and recreated during the next adapter run.

Here are the steps to follow:

1. Log in to each vROPs node using SSH.

2. Locate the following line in the Skyline adapter configuration file (usually located at /etc/vROps/skyline/skyline.conf):

Skyline

VROPS

CANCEL_OLDEST

3. Change the value of the cancellation-policy parameter from CANCEL_OLDEST to KEEP_ALL.

4. Restart the Skyline adapter service on each node to apply the new configuration.

After applying this configuration, the Skyline adapter will no longer automatically cancel and recreate alerts, preventing duplicate alert notifications. This solution ensures that all alerts are kept and displayed in the vROPs dashboard, allowing administrators to monitor their virtual infrastructure more effectively.

Conclusion

In conclusion, duplicate alert notifications in vROPs can be a frustrating issue for administrators. However, by adjusting the configuration of the Skyline adapter, this issue can be easily resolved. By following the steps outlined above, administrators can ensure that all alerts are kept and displayed in the vROPs dashboard, providing a more accurate picture of their virtual infrastructure’s performance and health.
