File Repository Server Performance Test

An Input File Repository server that is sized right and is capable of processing I/O requests quickly can alone enable users to rapidly generate new reports using the published report and program objects stored in the server. Likewise, if the Output File Repository server does not have enough space or is incapable of processing I/O requests rapidly, it cannot hold or serve completed documents for users. This is why, it would be good practice to keep an eye on the disk space usage and I/O activity on the Input and Output File Repository servers. The File Repository Server Performance test helps administrators do just that. This test monitors I/O requests to Input and Output File Repository servers and measures how well these servers handle these requests. In the process, the test indicates whether/not the servers are experiencing any processing bottlenecks. Additionally, the test monitors the disk space usage of the servers and proactively alerts administrators to a potential space crunch (if any) on the servers.

Target of the test : A SAP BOBI Node

Agent deploying the test : An internal/remote agent

Outputs of the test : One set of results for the Input and Output File Repository servers in the node monitored.

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.
Port	Enter the port to which the specified host listens. This should be the port at which the web application server hosting SAP BOBI listens.
JMX Remote Port	Specify the RMI port number of the BOBI monitoring application.To know the RMI port number of the monitoring application, refer to Enabling the Monitoring Application of the SAP BOBI Platform.
JNDI Name	Specify the lookup name for connecting to the JMX connector of the BOBI monitoring application. To know the JNDI name, refer to Enabling the Monitoring Application of the SAP BOBI Platform.
JMX User and JMX Password	Enter the credentials of an enterprise authenticated BOBI user belonging to the default monitoring users group.
Confirm Password	Confirm the password by retyping it here.
Node Name	Specify the name of the BOBI node being monitored.

Measurements made by the test

Measurement	Description	Measurement Unit	Interpretation
Active connections	Indicates the number of active connections from clients to this server.	Number	This is a good indicator of the load on the server.
Open files	Indicates the number of files that are currently being accessed in this server.	Number
Data write rate	Indicates the rate at which data is written to this server.	MB/Sec	A consistent drop in the value of this measure could indicate a drop in load or a processing bottleneck.
Data read rate	Indicates the rate at which data is read from this server.	MB/Sec	A consistent drop in the value of this measure could indicate a drop in load or a processing bottleneck.
Free disk size	Indicates the free space on the disk containing the server’s executable file.	GB	A high value is desired for this measure.
Free disk	Indicates the percentage of free space on the disk containing the server’s executable file.	Percent	A steady decrease in the value of this measure indicates that disk space on the server is getting depleted. This is a cause for concern.
