The hwevents file contains state change actions that are to be performed by the
splogd logging daemon. The fields in this file are:
frame Specifies the frame number (1- n) or * (asterisk) for all
frames.
slot Specifies the following:
• A number from 0-17
•
One of
−
NODES_ONLY (addresses 1 through 16)
−
SWITCH (address 17)
−
FRAME (address 0)
−
* (asterisk, all addresses)
−
NODES_AND_SWITCH (addresses 1-17)
−
FRAME_AND_NODES (addresses 0-16)
−
FRAME_AND_SWITCH (addresses 0 and-17)
variable Specifies a hardware variable. For example, nodePower,
Temp, LED7SegA.
operator Specifies how to compare the value. Acceptable values
a r e : = , < , > a n d ! = .
value Specifies the value of the variable to match the operator
wildcard (*) or a partial match with the wildcard at the end
(23*).
time Specifies if the function should be called at startup or
when the state changes, or both times. Valid options are
startup, change or both.
function Specifies the program to call when the event occurs.
There two special keywords for function If function is
SP_ERROR_LOG, error logging is performed provided that
syslog is set up and AIX error logging is set up to perform
SP logging. Refer to the setup_logd.
If function is SP_STATE_LOG, these state changes that
meet the statement
′
s criteria are logged to the file
/ v a r / a d m / S P l o g s / s p m o n / s p l o g d . s t a t e _ c h a n g e s . < t i m e s t a m p > .
Note that you must send a SIGHUP signal to splogd to close the current
state_changes.<timestamp> and to open a new one. For example:
kill -HUP <splogd_PID>
User Exit Arguments
When a user exit is called by splogd, the following arguments are passed:
1. A c or s depending on whether this call is for a change of state or to
provide the startup values for the variables being monitored.
2. For each variable being reported, the following arguments are passed:
•
Frame number
•
Node number
•
Variable name
•
Value of the variable. (Boolean values are expressed as TRUE or FALSE,
integers as decimal strings, and floating-point values as floating-point
strings.)
