> ### DiskBusyThresholdExceeded

> #### Message

> "Disk Busy Threshold Exceeded! Value: x, Threshold: y."

> #### Description

> Sent when a disk's configured threshold is exceeded.

> #### Type

> Polled

> #### Action

> Consider the following options to reduce the disk's load:

> - Spread databases across multiple disks which will increase the Progress Blocks in database buffers (-B parameter)
> - Add more disks
> - Request that your system administrator invest in faster disks.

> #### Notes

> These notes pertain to this alert:

> - Adding more disks to a system increases overall disk I/O because reads and writes can span across multiple disks. However, the performance results depend on how the multiple disks are grouped and how you structure your databases.
> - For information on how your Progress databases affect disk I/O, view the following Progress VSTs:
> - _ActBuffer._Buffer-OSRds
> Displays information about the number of database block reads from disk.

> - _ActBuffer._Buffer-OSWrts
> Displays information about the number of database block writes to disk.

> - _ActIOType
> Displays information about types of input/output activity, such as database reads and writes, BI and AI reads, total reads, BI and AI writes, and committed transactions.

> - _ActIOFile
> Displays information about input/output activity, including the number of reads, writes, and extends for each file.
