Database Disk Space Test

To ensure that a database disk always has sufficient space to store the critical data, you will have to continuously track the space usage of the disk. This will provide you with early pointers to potential space contentions and help you swiftly provide more space by adding more disks. The Database Disk Space test enables you to achieve this end. This test closely monitors how the database disk uses the space available to it, points you to the disks that are running out of space, and thus holds a mirror to space contentions on a disk.

Target of the test : A SAP BTP Neo Environment

Agent deploying the test : An internal/remote agent

Outputs of the test : One set of results for each Database in the target SAP BTP Neo Environment.

Configurable parameters for the test
Parameter	Description
Test Period	How often should the test be executed
Host	Host name of the server for which the test is to be configured.
PortNo	Enter the port to which the specified host listens. By default, this is 10002.
Subaccount	In SAP Cloud Platform Cockpit, one user account will have multiple subaccounts. So you can mention any one of the subaccount name in the Subaccount text box. To know how to determine the Subaccount, refer to Identifying the API Endpoint URL and Subaccount topic in Pre-requisites for Monitoring SAP BTP Neo Environment.
Database names	Specify a comma-separated list of database names pattern that need to be included for monitoring, by default. To know how to determine the name of Databases, refer to Determining the Name of HANA/ASE Databases to be Monitored topic in Pre-requisites for Monitoring SAP BTP Neo Environment.
User	For collecting the metrics, specify the Username in the User text box. The Username here refers to the Client ID created in SAP Cloud Platform Cockpit. To know how to create such a user (Client ID) in SAP Cloud Platform Cockpit, refer to Registering the eG Agent as an API Client topic in Pre-requisites for Monitoring SAP BTP Neo Environment.
Password	Specify the password in the Password text box. The Password here refers to the Client Secret created in SAP Cloud Platform Cockpit. To know how to create Password (Client Secret) in SAP Cloud Platform Cockpit, refer to refer to Registering the eG Agent as an API Client topic in Pre-requisites for Monitoring SAP BTP Neo Environment.
Confirm Password	Confirm the password by retyping it here in the Confirm Password text box.

Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
Total free disk space	Indicates the amount of space in this disk that is currently free - i.e., available for use.	MB	Ideally, the value of this measure should be high. A consistent decrease in this value is a cause for concern.
Total free disk space percentage	Indicates the percentage of space in this disk that is currently unused.	Percent	A high value is typically desired for this measure. By comparing the value of this measure across disks, you can quickly isolate the disks that are running short of space. If the free space is alarmingly low for the disk, it indicates that the disk require more space. You can then consider making space by adding more disks.
Total usage disk space	Indicates the percentage of space in this disk that is currently used.	Percent	A low value is typically desired for this measure. By comparing the value of this measure across disks, you can quickly isolate the disks that are utilizing space excessively. If the used space is alarmingly high for the disk, it indicates that the disk is rapidly running out of space. You can then consider making space by adding more disks.
