Fujitsu Host I/O Test
This test monitors the performance of each volume based on the interaction between the server/host requesting data to each volume. This helps the administrators identify the volume that is taking too long to service read and write requests.
Target of the test : Fujitsu Storage AF/DX
Agent deploying the test : A remote agent
Outputs of the test : One set of results for each volume in a Fujitsu Storage AF/DX that is currently launched.
Parameters | Description |
---|---|
Test Period |
How often should the test be executed. |
Host |
The nick name of the Fujitsu Storage AF/DX component for which this test is to be configured. |
Port |
Refers to the port at which the specified host listens to. By default, this is NULL. |
Timeout |
Specify the duration (in seconds) within which this test should time out in this text box. The default is 10 seconds. |
Use SUDO |
To run this test and report metrics, the eG agent install user should have permissions to run the rndc stats command and read from the statistics-file. If the eG agent install user possesses these privileges, then set the Use SUDO flag to No. If the eG agent install user does not have the required permissions, then do the following:
|
High Security |
This flag is applicable only when the target Linux host is monitored in the agentless manner. In highly secure environments, eG Enterprise could not perform agentless monitoring the Fujitsu Storage running on a Linux host using SSH. To enable monitoring of the Fujitsu Storage in such environments, set the HIGH SECURITY flag to Yes. It indicates that eG Enterprise will connect to the target Fujitsu Storage in a more secure way and collect performance metrics. By default, this flag is set to No. |
Measurement |
Description |
Measurement Unit |
Interpretation |
---|---|---|---|
Read IOPS |
Indicates the number of read operations performed on this volume per second. |

|
Write IOPS |
Indicates the number of write operations performed on this volume per second. |
Operations/sec |
|
Read throughput |
Indicates the rate at which this volume processes read requests. |
MB/Sec |
|
Write throughput |
Indicates the rate at which this volume processes write requests. |
MB/Sec |
|
Read response |
Indicates the average read response time taken by this volume. |
Milliseconds |
Compare the value of these measures across volumes to find out which volume is taking too long to respond to read/write requests. |
Write response |
Indicates the average write response time taken by this volume. |
Milliseconds |
|
Read cache |
Indicates the percentage of read cache hit ratio in this volume. |
Percent |
Ideally, a high value of this measure is desired. |
Write cache |
Indicates the percentage of write cache hit ratio in this volume. |
