File System Detail - Local (PD_FSL)
- Organization of this page
Function
The File System Detail - Local (PD_FSL) record stores the performance data showing the status of the local file system capacity at a given point in time. A record is created for each local file system. This is a multi-instance record.
- Notes:
-
-
In HP-UX, Solaris, and Linux, the file system area for a general user is defined as the sum of the file system area used and the file system area that is available. The file system area for a superuser also includes a reserved file system area. In AIX, because there is no reserved area, there is no difference between the file system area for a general user and that for a superuser.
-
In HP-UX, Solaris, and Linux, the number of i nodes is defined as the sum of the i nodes used and the i nodes that are available. The number of i nodes for a superuser also includes the number of reserved i nodes. In AIX, because there are no reserved i nodes, there is no difference between the number of reserved i nodes for a general user and that for a superuser.
-
In specialized file systems, it may not be possible to collect performance data. For example, a remote file system whose remote host name cannot be acquired as a virtual local file system may be treated as a local file system.
-
The basic block size (FFBS: Fundamental Filesystem Block Size) used in the field table of this record is the allocation unit used during file system creation. The number of blocks that corresponds to the basic block size is called the basic block count. The logical block size (PFBS: Preferred Filesystem Block Size) is the allocation unit used during input/output operations. The number of blocks that corresponds to the logical block size is called the logical block count.
-
In Solaris, /system/contract or /system/object is not collected.
-
In Solaris, do not use a colon (:) in a file system name. If a colon is used by mistake, the file name is treated as a remote file system and collected as the PD_FSR record.
-
When information is collected into the PD_FSL record, a system call is issued at the data collection interval. Because collecting information using the system call involves file system access, an attempt to execute the umount command to unmount the file system during information collection might fail. If execution of the command fails, re-execute the umount command at a time different from the collection interval.
-
If a special file system (such as a pseudo file system) exists in the system, the PD_FSL record behaves in either of the following ways:
• The PD_FSL record does not create instances of the record. (File systems such as /proc file systems perform this behavior.)
• The PD_FSL record outputs the values collected from the OS directly as record information. In this case, performance data that is output is indeterminate.
-
Depending on the system status, the number of instances in the PD_FSL record might be different from the result of the df command. If they are different, estimate the disk space requirements based on the actual collection results.

A value between 0 and 32,767 seconds can be specified (a value within the range specified for Collection Interval). Use this item to distribute the collection load, because executing data collection all at once results in concentration of the processing workload. Note that the data collection duration to be recorded is the same as the Collection Interval, regardless of the value specified for Collection Offset.
When changing the Collection Offset value, specify a value that takes into account the impact of the collection processing load.
