ISRs are interrupt service routines used within the unit for operational tasks. ISR Utilization provides
information concerning the amount of time spent completing these processes. ISR Utilization information
is only available for 3rd Gen systems and will always show 0 on 2nd Gen units.

Longest times (top 3) spent in an interrupt routine, in microseconds.
S YSTEM U TILITY > S YSTEM U TILIZATION > P ERFORMANCE > M AX ISR D URATION #1-3 (ID)
Process IDs of the interrupts with the longest processing times (top 3).
F ROM P OWER -U P Max CPU utilization since the last Total Access 600
Series restart.
L AST S ECOND Max CPU utilization in the last second. This is the
most current CPU utilization information.
F ROM L AST C LEAR Max CPU utilization since the last manual clear of
the performance statistics using the C
LEAR S TATS
command.
F ROM L AST C LEAR ISR utilization since the last manual clear of the
performance statistics using the C
LEAR S TATS
command.
ISR information provides useful statistics for ADTRAN’s Technical Support group but are
not intended for interpretation by the general audience.
