This document describes changes and updates that have occurred since the release NetApp KM for PATROL v1.6.00.
What's New
Coverage
NetApp Filers KM for PATROL 1.6.02 has been enhanced to fully support the monitoring of the CIFS protocol (Common Internet File System). This protocol is the most commonly used by NetApp Filers for sharing files with Windows clients.
The following Applications Classes were added to the KM to report performance data on the CIFS protocol:
Parameters
| • | OperationRate: number of CIFS operations done by the filer |
| • | CallRate: total number of CIFS calls received. |
| • | BadCallRate: total number of received CIFS calls rejected |
| • | GetAttributeOperationRate: total number of CIFS operations to get the attributes on a file or directory |
| • | ReadOperationRate: total number of CIFS Read operations on file or directory |
| • | WriteOperationRate: number of CIFS file locking requests |
| • | FileOpenCallRate: number of calls, via CIFS, to open a file or directory |
| • | FileLockingRequestRate: number of CIFS file locking requests |
| • | DiectoryOperationRate: number of CIFS directory operations |
| • | OtherOperationRate: number of CIFS operations that do not fall into the categories for Get Attributes, Read, Write, Lock, Directory Open and Open |
| • | SuspectOperationPercent: smoothed average of the number of events per second of the type frequently seen during virus attacks |
SEN_NA_CIFS_UTILIZATIONS
| • | ConnectedUsers: current number of CIFS users on the filer |
| • | Trees: current number of CIFS trees on the filer |
| • | Sessions: current number of active CIFS sessions on the filer |
| • | OpenFiles: current number of open CIFS files and directories on the filer |
| • | OpenDirectories: current number of open CIFS directories on the filer |
| • | OplockBreakWaitingFiles: number of open files waiting for oplock break messages to be sent |
| • | OplockAckWaitingFiles: number of open files waiting for acknowledgements to oplock break messages |
| • | ConnectedUsersPercenMax: current number of CIFS connected users in percentage of the maximum allowed. |
| • | TreesPercentMax: current number of CIFS trees users in percentage of the maximum allowed |
| • | SharesPercentMax: current number of CIFS shares in percentage of the maximum allowed |
| • | OpenFilesPercentMax: current number of open CIFS files and directories in percentage of the maximum allowed |
Fixed Issues
| • | The KM command <Remove> did not always properly remove the selected object |
| • | When switching from one thresholds management mode to another in the Threshold Mechanism box, existing thresholds were not migrated from one mode to another |
| • | The discovery could not always complete its process. Consequently, some components (ex: NFS Cache, vFiler) were not always associated to their related filers |
| • | The polling interval was not reset to its default value when re-initializing the product |
