MSSQL on Linux: Memory-Optimized Data Filegroup container free space (\%)

Microsoft.SQLServer.Linux.CollectionRule.Container.SpaceFreePercent (Rule)

Collects the amount of free space available in the Memory-Optimized Data Filegroup container, expressed as percentage of the sum of disk free space and the size of data stored in the Memory-Optimized Data Filegroup container.

Knowledge Base article:

Summary

The rule collects the amount of free space available in the Memory-Optimized Data Filegroup container, expressed as percentage of the sum of disk free space and the size of data stored in the Memory-Optimized Data Filegroup container.

The Memory-Optimized Data Filegroup Container folder typically grows over time as more data is added into Memory-Optimized Data tables.

When the available disk space on the drive where the database storage location is configured becomes too low, failures can occur, preventing successful processing of data, delaying user’s queries, or affecting other applications, which share the same allocation of disk space.

The resolution(s) for low available disk space depend upon the root causes, which must be investigated in each case when this issue occurs. The condition may be alleviated by any of many potential approaches:

Overridable Parameters

Name

Description

Default Value

Azure Maximum File Size (MB)

The maximum size of data file stored in Azure BLOB Storage. The workflow will consider this value as a maximum storage capacity for each file.

1048576

Enabled

Enables or disables the workflow.

Yes

Interval (seconds)

The recurring interval of time in seconds in which to run the workflow.

900

Synchronization Time

The synchronization time specified by using a 24-hour format. May be omitted.

 

Timeout (seconds)

Specifies the time the workflow is allowed to run before being closed and marked as failed.

300

Timeout for database connection (seconds)

The workflow will fail and register an event, if it cannot access the database during the specified period.
