Example: Identifying the performance issues of an application using Arctera InfoScale Operations Manager

As an administrator, one of your responsibilities is to ensure the optimum performance of the applications that are running in your data center. Performance issues of your critical applications can have significant negative effect on overall business. For example, if you fail to address long I/O access times for the storage network supporting your e-commerce transaction system, the seasonal surge in transactions could cause significant slowness and have financial implications on the business.

With the Storage Insight Add-on for Arctera InfoScale Operations Manager, you can get visibility from the application down to the spindle. Arctera InfoScale Operations Manager empowers you to view the detailed storage information of an enclosure. With this added visibility, you can perform storage management operations with confidence.

For detailed information about the storage enclosures in your data center and on using Storage Insight Add-on, refer to the Arctera InfoScale Operations Manager Add-ons User Guide.

In Arctera InfoScale Operations Manager, you can view the performance for various objects such as host, volume, disk by using interactive graphs. You can select an object and view graphs for multiple performance parameters.

A complete list of objects and the types of performance graphs is provided.

See About metered resources.

This example explains how you can use the performance graphs on the storage objects in Arctera InfoScale Operations Manager and the ability to view the application to the spindle mapping, to analyze the following problem:

Problem: The Oracle database that is installed on the LUNs, which are part of IBM XIV enclosure, is slow.

In this example, we use the following names:

Table: Example names

Object	Name
Oracle database	ora_db
Host that you use to access ora_db	lnx_host This host runs on Linux platform.
Volume, which is associated with ora_db	vxvm_vol
File system, which is associated with ora_db	vxfs_fs This File System is a VxFS file system.
Disks that are associated with the IBM XIV enclosure on which ora_db is installed	xiv_disk1 xiv_disk2

Any of the following can result in the poor performance of ora_db:

The lnx_host that contains ora_db may have many other applications running simultaneously on it. These applications can result in more CPU load on the host or the usage of more memory. If the CPU load or the memory usage exceeds the optimum value, it can affect the performance of ora_db.
To view the performance graphs for lnx_host associated with ora_db
The available file system size on vxfs_fs that is associated with ora_db may not be enough for the proper functioning of ora_db. Or the delay in the I/O time on vxvm_vol that is associated with ora_db can affect the performance of ora_db.
To view the performance graphs for vxfs_fs and vxvm_vol associated with ora_db
The delay in the I/O time on xiv_disk1 or xiv_disk2 that is associated with ora_db can affect the performance of ora_db.
To view the performance graphs for xiv_disk1 or xiv_disk2 associated with ora_db

To view the performance graphs for lnx_host associated with ora_db

In the Home page on the Management Server console, go to Server perspective, and select Manage in the left pane.
Expand Organization or Uncategorized Hosts to locate lnx_host.
Click the Performance tab.

To view the performance graphs for vxfs_fs and vxvm_vol associated with ora_db

In the Home page on the Management Server console, go to Server perspective, and select Manage in the left pane.
Expand Applications and expand Databases to locate ora_db.
Click the Volumes tab.
In the volumes details list, right-click vxvm_vol, and select Performance.

To view the performance graphs for xiv_disk1 or xiv_disk2 associated with ora_db

In the Home page on the Management Server console, go to Server perspective, and select Manage in the left pane.
Expand Applications and expand Databases to locate ora_db.
Click the Disks tab.
In the disks details list, right-click xiv_disk1 or xiv_disk2 and select Performance.

Performance charts for xiv_disk1

Performance charts for xiv_disk2

From the performance graphs of xiv_disk1 and xiv_disk2, you notice an issue with the performance of xiv_disk1. The performance graph of xiv_disk1 displays that the average read latency is higher than the optimum value and the bytes read is lower than the optimum value.

From the performance graphs, you have identified the low disk I/O issue of xiv_disk1. This issue can adversely affect the performance of the ora_db. You must understand the specific problem that results in the low disk I/O on xiv_disk1. To understand the specific problem, you must analyze the details of xiv_disk1. Understanding the cause of the problem can help you make appropriate decisions on addressing the performance issue of the ora_db.

As xiv_disk1 and xiv_disk2 are part of IBM XIV enclosure, you can view the detailed information on them with the help of Storage Insight Add-on.

Note:

You must configure the deep discovery for IBM XIV storage enclosures to view the details of xiv_disk1 and xiv_disk2.
