have purged a Collector’s RESTART file. For this reason, you may want

to start HP Shadowbase with the pulse feature disabled (i.e.,i.e.,

PULSERATE 0) and then alter the Consumer to enable them after

successful startup.

When enabled (i.e.,i.e., PULSERATE is > 0), the first pulse is not sent until

the PULSERATE interval expires. If you want one to be sent before this

period expires, use the Consumer’s PULSE command to send a pulse on

demand.

The default is 0 which means pulses will not be generated for this

Consumer. The valid range is 0 through 1209600 (14 days in seconds).

When greater than zero, the specified value must be longer than the

amount of time that the pulse will be tracked (a pulse is tracked while the

AUDMON is waiting for the ACK to come back). In other words, only one

pulse is “tracked” at a time, and another one cannot be sent until that

pulse is no longer being “tracked”.

The maximum amount of time that the AUDMON will track the pulse and

wait for the ACK is defined by the PULSEWAIT and

PULSEWAITREPEATS parameters. The pulse ACK is tracked for a

maximum of (PULSEWAIT * (PULSEWAITREPEATS + 1)) seconds.

Another pulse cannot be sent until this time expires, or the ACK for the

pulse comes back. The pulse generation rate must be set greater than

this time (PULSERATE must be set greater than this number). Note that

any pulse ACKs that come back after this time expires are still processed

and stored in the pulse file.

The PULSEWAIT can be set to 0, which means that the pulse ACK will not

be timed (or alarmed). When PULSEWAIT is 0, the PULSERATE can be

set to any frequency desired.

HP Shadowbase includes an edit to make sure that you do not set the

pulse generation (PULSERATE) and ACK wait intervals (PULSEWAIT,

PULSEWAITREPEATS) “too short” to cause extra overhead or alarming.

This parameter can be altered at any time. To disable the pulse feature,

alter PULSERATE to 0.
