systat. It’s common on BSD (FreeBSD, OpenBSD) and old Solaris. On Linux, installsysstator usetop/htopinstead — butsystat’s layout is unique.
This is where systat 132 hot shines. Under hot, each disk’s transfer rate (tps), kilobytes per second (kps), and queue length refresh instantly. You can literally watch a tar command appear as a green or white bar shooting across the disk column.
For a disk I/O spike, look for STATE = disk and high %CPU (waiting for I/O). Use iostat view to confirm. systat 132 hot
$ systat 132 hot
Your screen clears, and a dense table appears. You press : and then disk to focus on I/O. Suddenly, the da0 (disk) column jumps from 5% busy to 98% busy. The wait CPU column jumps to 40%.
You know instantly: It’s not the CPU. It’s the disk. Note: Not all Unix-like systems include systat
You kill the backup job, and within two refreshes (two seconds), the hot display drops back to idle.
If "132 hot" refers to a specific error code or a specific engineering dataset (e.g., "132 hot" being a temperature reading), please clarify, and I can provide a more targeted analysis. This is where systat 132 hot shines
Ignoring this alert is not an option. Here is what happens if you continue operation:
| Temperature Range | Consequence | | :--- | :--- | | 85°C - 95°C | Data drift. Analog input readings become non-linear. | | 95°C - 105°C | Solder joint embrittlement. Intermittent connection loss. | | 105°C+ | Permanent damage to the FPGA chip. Unit becomes bricked. |
