What's New
New Metrics
• | Quota and Cluster quota metrics are now available through the STOFS dataset. |
• | These metrics were added to the STOSSW dataset to provide bandwidth information for Ethernet ports (in 7-mode and Cluster-mode): |
▪ | BYPORT_BANDWIDTH: it exposes the port bandwidth |
▪ | BYPORT_IN_UTIL: it exposes the port inbound utilization in percentage |
▪ | BYPORT_OUT_UTIL: it exposes the port outbound utilization in percentage |
• | The new metric ST_AGGREGATE_OVERCOMMITMENT_PCT was added to expose the percentage of capacity configured in aggregate exceeding the aggregate capacity. |
Logs
• | Log files can be downloaded from the BMC TrueSight Capacity Optimization console. |
Changes and Improvements
• | The computation method used to calculate the volumes capacity metrics has been standardized for both 7-mode and cluster-mode. It now includes the total data space and the snapshot reserve. Impacted metrics are: |
▪ | ST_CONFIG_SIZE and ST_CAPACITY: they expose the total data space and the snapshot reserve |
▪ | ST_AVAILABLE_CAPACITY: it exposes the available data space |
▪ | ST_AVAILABLE_CAPACITY_PCT: it exposes the ratio of the available data space to the capacity |
▪ | ST_CONSUMED_CAPACITY : it exposes the sum of used space plus snapshot reserve |
▪ | ST_CONSUMED_CAPACITY_PCT: it exposes the ratio of the consumed capacity (sum of used space plus snapshot reserve) compared to the capacity |
▪ | ST_VOLUME_SNAPSHOT_RESERVE_SIZE: it exposes the snapshot reserve space |
▪ | ST_VOLUME_SNAPSHOT_RESERVE_USED: it exposes the actual space used by snapshots |
• | The ST_FILER metric now exposes the controller name. |
• | Display names have been improved in 7-mode for vFilers IDs, vFilers instance names, and Volumes (Shares) IDs. Please note that history will be lost for these entities when upgrading to version 6.0.00. |
• | The Log message "Class xxx ignored in file" was improved to indicate why entities have been ignored. |
• | The discovery log is now available as a separate file. |
• | The descriptions for the ST_POOL_SUBSCRIBED_CAPACITY, ST_SIZE, and ST_SYSTEM_SUBSCRIBED_CAPACITY metrics have been reviewed. |
Fixed Issues
• | An exception occurred while collecting volume information. |
• | When some required metrics could not be obtained from the NetApp DATA ONTAP API, a NullPointerException error was triggered which prevented the ETL to properly discover NetApp filers. |
• | Exceptions occurred in cluster mode: |
• | when discovering disk instances and when no shelf information was available. |
• | when discovering volumes. |
• | Ethernet ports were missing when using Data ONTAP 8.2.1 in cluster mode. |
• | The value of the ST_FC_RATE metric was not correct. |
• | Negative values were sometimes reported in cluster mode for the BYPORT_OUT_BYTE_RATE, BYPORT_BYTE_RATE, and BYPORT_IN_BYTE_RATE metrics. |
• | Storage - Volume entities are not displayed under the Storage Area Network entity anymore in the Worskpace navigation tree. |
• | The vFiler ID and name have been changed to prevent conflicts when the UUID was not unique. The vFiler name now displays the controller host name. |
• | Log files were not properly deleted on log rotation. |
