In vRealize Operations, you can access a series of pre-defined alerts that give you immediate insight into problems when they arise. Many companies also use custom alerts to meet their unique business processes. In this blog post, I will highlight how you can create your own alert definitions and create notifications for the custom alert, making it easy to generate an email for those specific notifications.
For the custom alert I’ll cover in today’s blog post, we’ll focus on a specific use case where a DBA wants to know when an Oracle tablespace exceeds 85% of its capacity. When this occurs, the DBA would like an email sent to her whenever it’s triggered so she can start to add space before it runs out completely.
In this case, we are not currently capturing the percent of usage on a tablespace, but have been capturing the total space in bytes and amount of free space in bytes. To compute the percent of space used, you will need to create a super metric within vRealize Operations.
Now that we’ve walked through how to create a custom alert, first by defining a symptom and then by creating the actual alert. In the second blog post in this series, I’ll provide insight into how to email the custom alert that we created.
