Configuring Fast SE Offline Detection
You can detect offline SEs more quickly if you enable the Fast Detection of Offline SEs feature.
If Fast Detection of Offline SEs is not enabled, the CDSM waits for at least two “getUpdate request”
polling periods before declaring the SE offline.
If Fast Detection of Offline SEs is enabled, the CDSM waits until the value displayed in the Maximum
Offline Detection Time field, located on the Configure Fast SE Offline Detection page, is exceeded.
Communication between the SE and CDSM using User Datagram Protocol (UDP) allows faster
detection of SEs that have gone offline. UDP heartbeat packets are sent at a specified interval from each
SE to the primary CDSM in a CDS network. The primary CDSM tracks the last time it received a UDP
heartbeat packet from each SE. If the CDSM has not received the specified number of UDP packets, it
displays the status of the nonresponsive SEs as offline. Because UDP heartbeats require less processing
than a getUpdate request, they can be transmitted more frequently, and the CDSM can detect offline SEs
much faster.
An SE is declared offline when it has failed to contact the CDSM for a getUpdate request (get
configuration poll) for at least two polling periods.
Note In CDS networks with heavy traffic, dropped UDP packets can cause the CDSM to incorrectly report the
status of SEs as offline. To avoid this problem, configure a higher value for dropped UDP heartbeat
packets.
System.monitoring.enable SE statistics monitoring (enable or disable).
System.monitoring.monthly
ConsolidationFrequency
Frequency (in days) with which the CDSM consolidates daily
monitoring records into monthly records.
System.monitoring.record
LimitDays
Maximum number of days of monitoring data to maintain in the system.
System.repstatus.update
Enabled
Replication status periodic calculations on an SE (enable or disable).
System.repstatus.updateRate Rate of replication status periodic updates calculated on an SE (in
minutes).
System.repstatus.updateRate
Sec
Rate of replication status periodic updates calculated on an SE (in
seconds). The default is 600 seconds. Setting this rate overrides the
update rate set in minutes.
System.repstatus.updateSync
Enabled
Sending summary replication status with requested detailed status
(enable or disable).
