What's New
| • | The ETL now provides support for WQL query in WBEM client based on SBLIM method. |
| • | The parameters collection can now be performed at different rates to maintain a suitable refresh rate of the parameters and scale large environments. The following specific polling cycles per devices have been implemented: |
| ▪ | Storage Systems, Controllers and Ports are collected at every run |
| ▪ | Storage Pools and Disks are collected once per hour |
| ▪ | Volumes (and Host information) parameters are collected once per day |
Changes and Improvements
| • | Code robustness has been improved. |
| • | Object discovery is performed once per day instead of once per hour to improve the monitoring performance on large environments. |
| • | The mechanism that handles the parsing of WBEM queries has been improved to reduce the consumption of CPU and memory resources. |
| • | The service activity trace in service log files (also displayed in the log screen of the ETL tasks section) has been improved. The service loading is now logged in a serviceLoading.log dedicated file. |
| • | The discovery or the collect of metrics is automatically interrupted when the time dedicated to these processes exceeds 3 times the configured service’s period. |
| • | Back End Fiber Ports (FC Ports) are no longer discovered: the collected information from the Back End Fiber Ports were not representative of the real data traffic of the disk array. |
| • | The SQLite store was replaced by a binary files store to avoid performance issues. |
| • | New computation methods for Symmetrix storage systems: |
| ▪ | The ST_AVAILABLE_FOR_STORAGE_POOLS metric exposes the available capacity for Storage Pools or for Traditional Volumes creation. |
| ▪ | The ST_AVAILABLE_IN_STORAGE_POOLS metric exposes the available capacity in Storage Pools. |
| ▪ | The ST_CAPACITY metric of the storage systems is now the sum of the ST_AVAILABLE_FOR_STORAGE_POOLS metric and the sum of Storage Pools and Traditional Volume capacities. |
| • | The error message displayed when querying an SMI-S provider that doesn't support the EMC namespace has been improved to be more explicit. |
Fixed Issues
| • | An error occurred when populating Run History on BCO 9.5.01 or higher. |
| • | The NullPointerException does not occur anymore when discovering Disk Groups. |
| • | Relations between Volumes and Storage Pools were missing in the BCO workspace. |
| • | The value of the ST_SYSTEM_IO_RATE metric is now null when the total number of operations per second performed by the system could not be computed. |
| • | The ST_POOL_SUBSCRIBED_CAPACITY metric for storage pools was not properly calculated when FAST policies were enabled in EMC Symmetrix/VMAX. |
