Tokyo SGI Server Performance Data This is Performance co-pilot (PCP) data for the Tokyo server at Silicon Graphics International (SGI). It characterizes the server performance as either `good` (1) or `bad` (0).
The instances are measurements generated by the PCP software every five seconds. See the PCP manual for further details.
Attribute Information
The attributes are interpreted as follows:
- runq: Average number of runnable processes in main memory (mem) and in swap memory (swp) during the interval.
- memory: The free column indicates average free memory during the interval, in Kilobytes. The page column is the average number of page out operations per second during the interval. I/O operations caused by these page-out operations are included in the write I/O rate.
- system: System call rate (scall), context switch rate (ctxsw) and interrupt rate (intr). Rates are expressed as average operations per second during the interval.
- disks: Aggregated physical read (rd) and write (wr) rates over all disks, expressed as physical I/O operations issued per second during the interval. These rates are independent of the I/O block size.
- cpu: Percentage of CPU time spent executing user code (usr), system and interrupt code (sys), idle loop (idl) and idle waiting for resources, typically disk I/O (wt).
