started appearing on Ebay at the under $100 price mark about a year

Nice tip, though I won't be buying one for each of my 26 spans. 
To the OP: if you're willing to open the box, there is usually a DB-9s
on the front of the smartjack you can plug your laptop into... it's
not actually "your" interface, but it will give you the numbers.
You also run the risk of screwing up the span, which I do not assume
hereby.

Hello,
In Asterisk you can type "zap show status" to at least show you some
basic error information:
CLI> zap show status
Description Alarms IRQ bpviol CRC4
wanpipe1 card 0 OK 0 0 0
wanpipe2 card 1 OK 0 0 0
wanpipe3 card 2 OK 0 0 0
wanpipe4 card 3 RED 0 0 0
I also just want to mention that on Sangoma T1/E1 cards you get
several tools for looking at the errors and statistics for each
circuit with the wanpipe drivers.
Here are some examples of the info you get:
----------------------------------------------
w3g1: AFT OPERATIONAL STATISTICS
----------------------------------------------
Number of frames transmitted: 17
Number of bytes transmitted: 136
Transmit Throughput: 0
Transmit frames discarded (length error): 0
Transmit frames realigned: 0
Number of frames received: 17
Number of bytes received: 136
Receive Throughput: 0
Received frames discarded (too short): 0
Received frames discarded (too long): 0
Received frames discarded (link inactive): 0
HDLC link active/inactive and loopback statistics
Times that the link went active: 17
Times that the link went inactive (modem failure): 16
Times that the link went inactive (keepalive failure): 0
link looped count: 0
And there is a lot more information in there that helps to debug and
monitor troubled circuits.

Using asterisk 1.4.19 and zaptel 1.4.10

Many moons ago I use to used a program called zttool. It allowed looking
at spans and the alarm state and bipolar errors and bit errors etc. You
could also see which channels were in use and look at signaling bits.
Anyhow this program sits in the zaptel directory. You may want to check
it out.

It compiles by default with Zaptel at this point, IIRC. Very handy tool |

Around here, the telco locks that cabinet and there is a user
id/password required to use that craft interface. (I have a key, but
then I worked for the telco for 23 years and have a few insider tools
laying around)

Not only that, but Jay's suggestion is going to give you the performance
monitoring data off the smartjack itself, not off of any portion of the
span beyond the smartjack.
So, if you are receiving errors on the part that runs to the CSU/DSU,
or, if you have an outboard CSU/DSU, also the DTE portion beyond it,
well, you won't see those.
You might get lucky and see errors in transmission (arrival at the
smartjack from the customer data side) since many error-causing
phenomena tend to apply symmetrically, but maybe not.

They are indeed barrel locked, but all on the same key, and some kind
soul left us one (and the recent special service guy didn't take it),
and he tells me, off the record, that Verizon doesn't appear to
password the interface in this market, so far as he knows.

This is an excellent point that I did indeed overlook. Our demarcs are
extended, and I might myself get bitten by this. Guess I'm gonna go
hit eBay.
These things are smart CSU's, right?
