Debugging options, Example | HP File System Extender (FSE) instruction

Debugging options

HSM_DEBUG_LEVEL

This variable represents the level of detail that FSE processes will track in their debug files. Note that each debugging level includes all debugging information from lower levels.

The following table represents the values the HSM_DEBUG_LEVEL variable can take, their corresponding levels, and their descriptions.

Option value	Debugging level	Description

L	1 — Low	Very little trace information will be
		logged in files, producing less debug
		overhead and small debug files.

N	2 — Normal	The usual level of detail in debug
		trace files.

A	3 — API	Trace third-party API calls (CORBA,
		Firebird…).

D	4 — Detail	Trace all process details, which can
		produce a lot of debug output.

Example
HSM_DEBUG_LEVEL=A

HSM_DEBUG_FILE

The following table represents the values the HSM_DEBUG_FILE variable can take and their descriptions.

Option value	Description

""	Debugs will be written to the standard output stdout.
(empty string or variable commented out;
default value)

.	Debugs will be written to files (one per FSE process) in a directory,
(dot)	depending on the platform:
(dot)
	Linux specific
	/var/opt/fse/log/debug
	Windows specific
	%InstallPath%\var\log\debug
	The value of %InstallPath% depends on the choice made in the FSE
	installation process. It defaults to
	C:\Program Files\Hewlett-Packard\FSE.

FileName	All FSE processes will print their trace data into the file named
	FileName.
	Linux specific
	The location of the file is /var/opt/fse/log/debug/FileName.
	Windows specific
	The location of the file is
	%InstallPath%\var\log\debug\FileName.

HP recommends to use the value . (dot), which results in each process producing its own trace file. The other two cases ("" and FileName) are for special purposes only and should not be used unless required by HP technical support personnel.

File System Extender (FSE) specifications

HP File System Extender (FSE) is a sophisticated solution designed to optimize data storage management for enterprises that deal with large volumes of unstructured data. This technology addresses the challenges of data growth and the need for effective data retention strategies, enabling organizations to store and manage their information more efficiently.

One of the main features of HP FSE is its ability to intelligently migrate data between primary and secondary storage. By utilizing policies that determine when to move infrequently accessed files to lower-cost storage environments, FSE helps reduce the strain on primary storage systems and saves on costs associated with high-performance storage solutions. This tiered approach to data management ensures that organizations can access the data they need quickly while still maintaining an efficient overall storage architecture.

Another notable characteristic of HP FSE is its seamless integration with existing storage infrastructures. The solution works with a variety of storage systems, allowing organizations to utilize their current investments without the need for significant changes to their infrastructure. This interoperability is powered by advanced technologies that facilitate data migration and retrieval, ensuring a smooth transition for organizations looking to optimize their storage strategies.

Additionally, HP FSE is equipped with robust reporting and analytics capabilities. This functionality provides organizations with insights into their storage usage, helping them understand data patterns and optimize their storage environments accordingly. By having visibility into which files are accessed most frequently and which are rarely used, organizations can make informed decisions on data retention policies and storage management.

Security is paramount in data management, and HP FSE addresses this concern by implementing advanced data protection features. This includes data encryption, secure access controls, and compliance with industry regulations, ensuring that sensitive information is safeguarded throughout its lifecycle.

Overall, HP File System Extender is a comprehensive data storage solution that combines intelligent data management, seamless integration, insightful analytics, and robust security features. By leveraging these capabilities, organizations can efficiently manage their unstructured data, lower costs, and enhance operational efficiency, making it an invaluable tool in today’s data-driven landscape.
