Unable to specify pool name when using "zpl" script

I have a pool named "tank" that I'd like to observe performance with the "zpl" script, but I can't seem to do that with the "-p" option:
```
$ sudo estat zpl -p tank
/usr/bin/estat: option -p not recognized
```
```
$ dpkg-query -W performance-diagnostics
performance-diagnostics 1.0.0-delphix-2020.07.11.03
```
