Monitored items definitions

Triggered actions section of the configuration file

[action]

#action contains available actions to be taken in case a threshold is crossed.

#Two actions are predefined and will be used to send e-mails in case

#the threshold is crossed upwards (email_ge) or downwards (email_lt)

#free defined actions may follow here. Note that the action is called in

#a shell environment. The logfile will contain the output of the command.

#There are variable parameters being replaced at runtime :

#%%MOUNTPOINT%% will be replaced by the corresponding mountpoint

#%%HOST%% will be replaced by the HOST where the filesystem is located

#%%P-STATUS%% will be replaced by the partition status.

stopsystem-ge: fse --stop

umount-ge: mymount.sh %%MOUNTPOINT%% %%P-STATUS%%

mount-ge: mymount.sh %%MOUNTPOINT%% %%P-STATUS%%

clt-umount-ge: %%HOST%%:mymount.bat %%MOUNTPOINT%% %%P-STATUS%%

clt-mount-ge: %%HOST%%:mymount.bat %%MOUNTPOINT%% %%P-STATUS%%

NOTE: The actions definitions provided in the configuration file are given only as an example, they are not used by default. To use them, they have to be specified in the monitored items definitions section. For more information, see section ”Monitored items definitions” on page 190.

A monitored item definition section is marked by a string representing the item name

([MonitoredItem]). When specifying a monitored item name, pay attention to the following requirements and limitations:

•The name is case-sensitive.

•If used for an HSM file system, the monitored item name should match the name of the corresponding FSE partition as defined in the FSE partition configuration file.

•You cannot use the name action, system, or mail for a monitored item name.

Each monitored item definition section defines the following:

•the file system type of the monitored item

•mount point (on Linux systems) or full path (on Windows systems) of the monitored item

•critical and warning thresholds for the monitored item and the assigned actions — every threshold has exactly one action assigned

A threshold defines the percentage of the used capacity on the monitored file system or on the FSE media pool assigned to the monitored file system. Thus, the actions defined for any monitored file system are started if the threshold set is crossed either on the monitored file system or on the assigned FSE media pool.

IMPORTANT: For a file system, the physically available space and not the space provided to users is monitored. For example, on Linux platforms using Ext3 file systems, by default only 95% of the disk storage space can be used by users of the file system, the rest is reserved for Linux operating system purposes. If an HHM threshold is set to 90%, the defined action will start when there is only 5% of the space assigned by the operating system to users left.

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.
