Object Categories for Performance Counters

Supported Resources (Objects) Performance Category Description

/servers

DataCore Servers

Metrics related to initiator and target I/O operations, cache, the poller, and support bundles for the DataCore Servers.

/pools

Disk pools

Metrics related to I/O operations, disk pool performance and usage.

/hostgroups

Host groups

Metrics related to initiator operations for the group. The initiator commands that the hosts in the group issued tos across all SCSI ports.

/scsiports

Host SCSI ports

Metrics related to total I/O operations to and from the selected host ports.

/hosts

Hosts

Metrics related to initiator operations. The initiator commands that the specific host issued tos across all SCSI ports.

/logicaldisks

Pass-through virtual disk sources

Metrics related to total I/O operations on the storage sources of virtual disks created from pass-through disks. Mirror I/O does not contribute to these counters.

/physicaldisks

Physical disks

Metrics related to total I/O operations for the selected physical disks.

/poolmembers

Pool physical disks

Pool metrics related to the selected physical disks in a pool.

/poollogicaldisks

Pool virtual disk sources

Metrics related to total I/O operations on the storage sources of all virtual disk created from pools.*

Mirror I/O does not contribute to these counters.

*Does not include virtual disks created from pass-through disks.

/rollbackgroups

Rollback groups

Metrics related to total I/O operations, cache, and replications for the selected rollback groups.

/servergroups

Server groups

Metrics related to initiator and target I/O operations between storage servers in a server group.

/scsiports

Server SCSI ports

Metrics related to initiator and target I/O operations and pending commands for the selected server ports.

/sharedpools

Shared disk pools

Metrics related to total I/O operations and the amounts allocated, available, in reclamation, transferred, migrated and reserved for the selected shared disk pools.

/sharedphysicaldisks

Shared physical disks

Metrics related to total I/O operations and the amounts allocated, available, transferred, recovered, remaining to recover, and in reclamation for the selected shared physical disks.

/snapshotgroups

Snapshot groups

Metrics related to total I/O operations, cache, replications, and snapshots for the selected snapshot groups.

/snapshots

Snapshots

Metrics related to total snapshot I/O operations, data migration, and delta between virtual disk source and the snapshot destination for the selected snapshot virtual disks.

/virtualdiskgroups

Virtual disk groups

Metrics related to total I/O operation, cache, replications*, and the migration of virtual disk data. Mirror I/O does not contribute to the virtual disk counters.

*Replication performance counters generated for the "active" virtual disk can be viewed from the performance tool for the "standby" virtual disk.

/virtualdisks

Virtual disks

Metrics related to total I/O operations, cache, replications*, and the migration of virtual disk data. Mirror I/O does not contribute to the virtual disk counters.

*Replication performance counters generated for the "active" virtual disk can be viewed from the performance tool for the "standby" virtual disk.

/virtuallogicalunits

Virtual logical units

Metrics related to total I/O operations and data transfers using a specific path and logical unit number (LUN).

/targetdevices

Virtual target devices

Metrics related to total I/O operations on all paths to the particular target port. Directional.

/targetdomains

Virtual target domains

Metrics related to total I/O operations on all paths between two particular computers (hosts and servers).

Example

Requests the counter statistics for the specified object id, which is the pool named "Disk pool 1 on StorageSvr001". One object is returned.

Certain REST clients require that "unsafe" ASCII characters in the request be replaced with a "%" followed by two hexadecimal digits.

Request:
