asterisk users - Jan 2015 - Best way to get dahdi status

I'm creating an app that needs to read the status of all dahdi spans and
channels, etc.  (whatever is needed to tell a user the state of their DAHDI
connections).


What is the best way to do that?  I see dahdi-tools available from the command
line, asterisk CLI commands, and AMI commands.  What is the best way to get the
status at a detail level?

For analog and raw span information (line mode (E1/T1), alarms,
current analog configuration, etc..), I think using either
dahdi_scan or the attributes in
/sys/bus/dahdi_devices/devices/<device>/span-<spanno> is your best
bet.

Maintenance counters on digital spans (timing slips, bit errors, etc..) is
returned via:

  $ dahdi_maint -s <spanno>

For information about whether your PRI is up, you have to ask
Asterisk since the drivers do not handle the PRI protocol. I don't
know if it is the *best* way, but I use:

  $ asterisk -rx 'pri show spans'
