Configuring EPICenter to Generate Alarms for SNMP-Unreachable
Devices at Each Poll Interval
EPICenter periodically checks the SNMP reachability status of managed devices, using a default poll
interval of 5 minutes. If a managed device is unreachable through SNMP, an alarm is generated in
EPICenter (and e-mail notifications are sent, if this is part of the alarm definition).
The default behavior is for the alarm to be generated only once, when the device is first found to be
SNMP-unreachable. No further alarms are generated, although EPICenter keeps polling the device at
the configured SNMP poll interval.
Starting with this release, you can configure EPICenter to generate SNMP unreachable alarms at each
poll interval when a managed device is not SNMP reachable, instead of just once. For example, if the
SNMP poll interval is 5 minutes, EPICenter would generate a new alarm every 5 minutes as long as the
device is SNMP unreachable.
To configure EPICenter to generate alarms for SNMP unreachable devices at each poll interval, do the
following:
1 Using a text editor, open the
management.properties file, which resides in
<EPICenter_install_dir>/extreme.war on the EPICenter server.
2 Change the value of the
EmitSnmpUnreachableEventAlways property to TRUE. This causes an alarm
to be generated each time EPICenter polls the device and finds it to be SNMP unreachable.
The default value of
FALSE causes EPICenter to generate an SNMP unreachable alarm only once, when
the device is first found to be SNMP unreachable. (PD3-202315601)
Displaying Text In Telnet Windows
Starting in this release, the EPICenter Telnet window can display a maximum of 220 text characters on a
line. When the number of text characters displayed on a line exceeds the width of the Telnet window, a
scroll bar appears at the bottom of the window so you can display the additional text. The scroll bar
adjusts dynamically according to the number of characters being typed or displayed. (PD3-182606694)
Specifying the IP Address a Multi-homed Server Uses for
Configuration Uploads and Downloads
If the EPICenter server is a multi-homed machine, and configured with more than one IP address, by
default the server uses the IP address specified by the EPICENTER_SERVER_ADDRESS environment
variable to communicate with its managed devices.
Starting in this release, you can specify which of the multi-homed server’s IP addresses is used for
configuration uploads and downloads for specific devices or for a given network. This IP address does
not necessarily have to be the one specified by the EPICENTER_SERVER_ADDRESS environment
variable.
For example, if the multi-homed server has IP addresses of 192.168.254.1 and 136.159.39.1, with the
EPICENTER_SERVER_ADDRESS environment variable set to 192.168.254.1, you can specify that
EPICenter use address 136.159.39.1 for configuration uploads and downloads for devices in the
136.159.39.x network.
