Collector Command Descriptions

HP NonStop Shadowbase Command Reference Manual—785421-002

AUDITTRAIL PROCESSING SUMMARY – This section of the output

displays current audit trail position information for any audit trails being

read.

SEQ shows the Sequence number of the audit trail currently being

processed.

RBA shows the current position within the audit trail expressed as the

relative byte address.

EOF shows the number of times it encountered the end of the audit trail file.

WAIT shows the duration of time that the COLL is waiting for audit to show

up (sum of intervals over time from the time the Collector hit EOF on the

MAT audit trail until the next event shows up). This is influenced by the

delay parameters ADTSAMPLEDELAY or ADTEOFDELAY, as well as the

length of time that it takes for more audit to arrive and for arlib to

read/return it to the Collector. More specifically, when the Collector hits

eof on the audit trail, the timer duration starts and, based on the

ADTSAMPLEDELAY or ADTEOFDELAY parameters, the Collector will

then wait either that amount of time minimum before checking the audit

trail again (ADTEOFDELAY) or up to that amount of time

(ADTSAMPLEDELAY) before attempting to read audit again. The time

from when the timer starts until the next audit trail event arrives and is

returned to the Collector by arlib is the duration added to the “WAIT:”

statistic. If one does a STATS RESET and there is no audited I/O activity

on the system, then the WAIT duration should be close to the COLL’s

duration.

RESTART INFO (MAT POSITION) – This section of the output is to show

the RESTARTFILE checkpoint information (i.e.,i.e., the point in the TMF

audit trail where the Collector will start reading from if it has to restart).

SEQ shows the current audit trail Sequence number saved in the

RESTARTFILE.

RBA shows the restart position within the audit trail expressed as the

relative byte address.

TIME shows the restart point timestamp.

LAG (CUR) shows the difference between current time and the restart point

timestamp. When HP Shadowbase is caught up, and is not receiving any

audit (none getting generated) the restart point timestamp reflects the last

audit event read.

DIFF LTS shows the difference between the most recent audit trail event

read and the restart position timestamp. If the difference is greater than

100 hours, it will be displayed as “>100 HOURS”. (A “*” is displayed next

to the “DIFF LTS” field if the restart point is lagging behind the threshold

defined for the COLL CHKPTWARNDIFF parameter.)

BI-DIRECTIONAL RESTART INFO (MAT POSITION) – This section of

the output is to show the bi-directional RESTARTFILE checkpoint
