26 INTERPRETING SYSTEM LOGS
26.1 INTERPRETING MESSAGES IN THE EVENT LOG PAGE
Each line of the Event Log web page begins with a time and date stamp. However, some
of these lines wrap as a combined result of window width, browser preferences, and line
length.
26.1.1 Time and Date Stamp
The time and date stamp reflect either
◦ GPS time and date directly or indirectly received from the CMM.
◦ the running time and date that you have set in the Time & Date web page.

NOTE:
In the Time & Date web page, if you have left any time field or date field
unset and clicked the Set Time and Date button, then the time and date
default to 00:00:00 UT : 01/01/00.
A reboot causes the preset time to pause or, in some cases, to run in reverse.
Additionally, a power cycle resets the running time and date to the default
00:00:00 UT : 01/01/00. Thus, whenever either a reboot or a power cycle has occurred,
you should reset the time and date in the Time & Date web page of any module that is
not set to receive sync.
26.1.2 Event Log Data Collection
The collection of event data continues through reboots and power cycles. When the
buffer allowance for event log data is reached, the system adds new data into the log and
discards an identical amount of the oldest data.
Each line that contains the expression WatchDog
flags an event that was both
◦ considered by the system software to have been an exception
◦ recorded in the preceding line.
Conversely, a Fatal Error()
message flags an event that is recorded in the next line. Some
exceptions and fatal errors may be significant and require either operator action or
technical support.
An example portion of Event Log data is displayed in Figure 118. In this figure (unlike in
the Event Log web page)
◦ lines are alternately highlighted to show the varying length of wrapped lines.
◦ the types of event messages (which follow the time and date stamps and the file
and line references) are underscored as quoted in Table 60 and Table 61.
