Customizing the AWS Data Provider for SAP

Some settings are hard coded in the AWS Data Provider for SAP. You can override existing settings or add new settings. For example, when AWS adds new instance types, you can add these to the AWS Data Provider for SAP configuration.

The AWS Data Provider for SAP creates a database by reading the configuration information from the following files, in this sequence:

• It reads the config.properties file from the JAR (Java Archive) file of the data provider application.

• It reads the file from the installation directory in which the proxy configuration file is located. This file is required only if a user wants to override or extend the current configuration. Default locations are:

  • On Linux: /usr/local/ec2/aws-dataprovider/config.properties

  • On Windows: C:\Program Files\Amazon\DataProvider\config.properties

• It reads the file from https://s3.amazonaws.com/aws-data-provider/config.properties.

Syntax Rules for Configuration Files

• The configuration files require a comma after the last value in every row.

• Spaces are not ignored in strings. The entire string between the commas, including any spaces, is accepted as the value.

• If there are multiple rows with the same instance type, the existing value for that type is overwritten.

• Capitalization in strings is case sensitive.

User-Configurable EC2 Instance Types

The AWS Data Provider for SAP maintains a database of all relevant Amazon EC2 instance types for SAP.

Entries for EC2 instance types must be in a comma-separated list, as follows:

ec2type,i-type,cpu,core,threads,t-ecu,ecu,hthread,l-map,w-map,speed,p-ecu,

For example:

 ec2type,r3.8xlarge,2,16,2,32,1,thread,eth0,lan2,10000,true,       
      

where the following applies:

Field name	Content	Example	Type	Description
keyword	ec2type	—	String	A token to identify a record with an EC2 instance description
i-type (instance-type)	See list	r3.8xlarge	String	Instance type, which must match the EC2 instance metadata string
cpu (CPUs)	1 | 2	2	Integer	Number of sockets
core (Cores)	integer	16	Integer	Total number of processor cores
threads (threads per core)	1 | 2	2	Integer	Threads per core
t-ecu (total ECU value)	integer	32	Double	ECU value for previous-generation instance types that have ECU ratings; number of cores for post-ECU instance types
ecu (ECU per core)	double	1	Double	1 for all post-ECU instance types; total ECU divided by cores for previous- generation instance types that have ECU ratings
hthread (hyperthreading)	thread | core	thread	String	thread for hyperthreaded instance types; core for non- hyperthreaded instance types
l-map (Linux NIC mapping)	eth0	eth0	String	Linux mapping of network interface
w-map (Windows NIC mapping)	eth0	lan2	String	Windows mapping of network interface
speed (network interface speed)	1000 | 2000 | 10000	100000	Integer	Maximum speed of network interface, in KB
p-ecu (post ECU)	true | false	true	Boolean	true for modern instances that don’t have ECU ratings

User-Configurable EBS Volume Types

The AWS Data Provider for SAP maintains a database of all relevant EBS volume types for SAP.

Entries for EBS volume types must be in a comma-separated list, as follows:

voltype,ebs-type,sample-time,

For example:

 voltype,io1,60,         
        

where the following applies:

Field name	Content	Example	Type	Description
keyword	voltype	—	String	A token to identify a record with an EBS volume description
ebs-type (EBS-type)	io1 | gp2 | sc1 | st1	Io1	String	EBS type, which must match the EBS volume metadata string
sample-time	60 | 300	60	Integer	CloudWatch sample time, in seconds

Important

The sample time is required to calibrate the EBS metrics to the SAP monitoring requirements. Changes in the sample time will lead to incorrect EBS metrics in the SAP monitoring system.
