This metric represents how far, in minutes, the destination trails behind the source.
The rest of the information in this section is only valid for this metric when it appears in either the Enterprise Manager Grid Control or the Enterprise Manager Database Control (if applicable).
The following table shows how often the metric's value is collected and compared against the default thresholds. The 'Consecutive Number of Occurrences Preceding Notification' column indicates the consecutive number of times the comparison against thresholds should hold TRUE before an alert is generated.

SnapMirror Time lag between Source:%SMSource% and Destination:%SMDestination% is %value% minutes ,crossed warning (%warning_threshold%) or critical (%critical_threshold%) threshold. |
For this metric you can set different warning and critical threshold values for each unique combination of "Index", "Source", and "Destination" objects.
If warning or critical threshold values are currently set for any unique combination of "Index", "Source", and "Destination" objects, those thresholds can be viewed on the Metric Detail page for this metric.
To specify or change warning or critical threshold values for each unique combination of "Index", "Source", and "Destination" objects, use the Edit Thresholds page. See Editing Thresholds for information on accessing the Edit Thresholds page.
Derived using SNMP MIB object snapmirrorLag (1.3.6.1.4.1.789.1.9.20.1.6)
The snapmirrorLag object gives the lag in 'hundredths of a second'. Smtimelag (in minutes) is derived using ( (snapmirrorLag / 100.0) / 60.0 )
