Customizing the Amazon Data Provider for SAP

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

The Amazon Data Provider for SAP creates a database by reading the configuration information from the available config.properties, files in this sequence:

  • The JAR (Java Archive) file of the data provider application.

  • The installation directory. This file is required only if you want to override or extend the current configuration. The default directories are as follows:

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

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

  • The Regional S3 bucket. Replace <region> with the Region code for the Region (for example, us-east-1).

    https://aws-sap-dataprovider-<region>.s3.<region>.amazonaws.com/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 Amazon 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 Amazon 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.
