    I'm having a problem when running pscheduler monitor on a testpoint. I 
keep
    getting the following error.

    [root@perfsonar4 ~]# pscheduler plot-schedule
    Not sending PNG output to a tty.  Consider redirecting.

The schedule plotter produces non-human-readable output and won't write it to 
a terminal.  As the message says, consider redirecting it to a file.

    [root@perfsonar4 ~]# pscheduler monitor
    Traceback (most recent call last):
      File "/usr/libexec/pscheduler/commands/monitor", line 431, in <module>
        curses.curs_set(0)
    _curses.error: curs_set() returned ERR

The terminal used to log into the system is probably lacking some of the 
features the monitor requires.  (What does 'echo $TERM' return?)

The program should fail gracefully under those circumstances; it's a case 
that was never tested.  I've opened an ticket on it 
(https://github.com/perfsonar/pscheduler/issues/1046) and will have it 
corrected in the next release.
