 2 
 3 Syntax as a command:  intm {-control_args}
 4 
 5 
 6 Function:  prints out metering information for input/output multiplexer
 7 (IOM) channel interrupts.
 8 
 9 
10 Control arguments:
11 -channel N
12    prints out interrupt metering information only for IOM channel N.
13 -iom N
14    prints out interrupt metering information only for those channels on
15    IOM N.
16 -report_reset, -rr
17    generates a full report and then performs the reset operation.
18 
19 
20 -reset, -rs
21    resets the metering interval for the invoking process so that the
22    interval begins at the last call with -reset specified.  If -reset
23    has never been given in a process, it is equivalent to having been
24    specified at system initialization time.
25 -total, -tt
26    prints out only the total IOM and nonIOM interrupt metering
27    information.
28 
29 
30 Access required:  This command requires access to phcs_ or
31 metering_gate_.
32 
33 
34 Notes:  If the interrupt_meters command is given with no control
35 arguments, it prints a full report.

37 The following are brief descriptions of the metering information
38 printed out by interrupt_meters.
39 Int
40    is the number of interrupts which occurred.
41 Avg Time
42    is the average time (in milliseconds) needed to handle each
43    interrupt.
44 % CPU
45    is the percentage of total CPU time needed to handle the interrupts.
46 Name
47    is the name of the device on the channel.
48 
49 
50 The following are descriptions of the totals printed by
51 interrupt_meters.
52 Chan
53    is the total of all IOM channel interrupts.  The times printed are
54    based on the total time spent in the per-channel interrupt handlers.
55 Other
56    is the total of all IOM interrupts.  Each IOM interrupt may cause
57    the handling of several channel interrupts.  The times printed
58    include only that time in the common interrupt path and exclude time
59    spent in the per-channel handlers.
60 Total
61    is the total of all interrupts handled by the system.
