Re: [U2] USERS command in Universe

See the documentation for the BASIC !GET.USERS and !GET.USER.COUNTS subroutines in the UV/BASIC reference manual.

Technically speaking, the internal UV daemons are not consuming UV licenses (mostly!), hence do not qualify as UV users...

As mentioned by Jon Card - you can also capture the output of uvlictool - which will need to be parsed first - before it can be 'consumed' by your application. It's a good tool - as it gives you want UV thinks is consuming the licenses versus what the other internal routines think are active OS processes that may or may not be present/active. 

At times, there can be two different numbers output from these toolsets. Especially, if processes have crashed, hung or are infinite loops consuming large amounts or CPU/memory, etc but doing nothing useful...or in some instances some processes can be transient in nature and not stay active for long (for whatever reason).

PORT.STATUS is useful too, but you should be aware that only one user can execute this at any given time and it should be used sparingly on large user and/or busy systems (as it attempts to query the state of each UV process as it identifies each). Many UNIX systems require administrative access in order to use it as well (unless you make tweaks for your platform to allow non-root users, etc.).

Subject: [U2] USERS command in Universe


The HELP USERS doesn't really say anything useful.

When I do a LISTU I count 87 sessions
USERS says there are "74 users logged on the system"

That's close to what I might say are the "unique" users, since some people have more than one session.
But I can't get it exact.

Does USERS count phantoms? console jobs? jobs like that uvdlock and uvcleanup and uvsmm?
How about jobs from Uniobjects making it's brief connections (uvcs), are those USERS for the purpose of this verb?

And if there's any better documentation about exactly what USERS is doing, can you point it at me?

Thanks.
