Oracle ZFS Pool Capacity Test

ZFS groups underlying storage devices into pools and file systems, and LUNs allocate from this storage as needed. Storage is configured in pools that are characterized by their underlying data redundancy and provide space that is shared across all file systems and LUNs. Each node can have any number of pools, and each pool can be assigned ownership independently in a cluster.

This test monitors the pools in the target storage system and for each pool, this test reports its status, used space, free space, and total space. This helps the administrator to analyze the requirement of space by either adding more space to the pool or by deleting unnecessary data from the pool.

Target of the test : Oracle ZFS Storage System

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each controller:storage pool in the Oracle ZFS Storage System being monitored.

Configurable parameters for the test

Parameter	Description
Test period	How often should the test be executed.
Host	The IP address of the target system that is being monitored.
Port	The port number through which Oracle ZFS Storage System communicates. The default port is 215.
User, Password and Confirm Password	By default, this test uses the REST API commands to pull out the required metrics. To execute the REST API commands, the eG agent requires the permission of a local administrator user who has been assigned with Basic role and a custom role with Analytics authorization and read permission. Specify the credentials of such a user in the USERNAME and PASSWORD text boxes and confirm the Password by retyping it in the CONFIRM PASSWORD text box. To create a new user with the required permissions, refer Creating a new user on Oracle ZFS Storage System.
Timeout	Specify the time duration for which this test should wait for a response from the storage system in the TIMEOUT text box. By default, this is 60 seconds.

Measurements made by the test

Measurement	Description	Measurement Unit	Interpretation
Pool status	Indicates the status of the storage pool.		The values reported by this measure and its numeric equivalents are mentioned in the table below: Measure Value Numeric Value Offline 0 Other 50 Exported 60 Unavailable 70 Faulted 80 Degraded 90 Available 100 Note: By default, this measure reports the Measure Values listed in the table above to indicate the status of the storage pool.
Used space	Indicates the space used by this pool including data and snapshots.	GB	Ideally, the value of this measure should be low. If this value grows close to that of the Total Space measure, then you may consider adding more storage to the pool, or free up the space in the pool by deleting unnecessary data.
Free space	Indicates the amount of physical disk space available.	GB
Total space	Indicates the total space provided to this pool.	GB
Space used	Indicates the space usage in percentage.	Percent	A value close to 100% indicates that the pool is currently running out of space.
Space free	Indicates the percentage of physical disk space	Percent
