TimesTen支持SNMP，且在其安装目录下，有一个模拟网络管理的软件[$install_dir/demo/snmp/snmptrapd]，可以接收SNMP协议。下面是一个如何配置的例子：
- 配置snmp.ini，设置 –enable 为 1
$ vi $TIMESTEN/info/snmp.ini
$ cat snmp.ini
# snmp.ini - Resides in /var/TimesTen.
#
# An environment variable TT_SNMP_INI can be set to specify an alternate path for this file.
#
# Modify this file to set an alternate trap destination.
#
# disable snmp trap generation (remove the line or set to 1 to enable)
-enabled 1
# default community is "public"
-community "public"
# default trap destination is "localhost"
-trapdest "localhost"
# default trap port is 162, the default SNMP trap port
-trapport 162
- 切换到root用户，启动snmp后台监听。这个监听程序需要root权限启动。
$ su - root
# export MIBS=all
# /usr/sbin/snmptrapd -f -Lo -M /home/tt705/TimesTen/tt705/mibs/TimesTen-MIB.txt
2008-07-29 11:44:37 NET-SNMP version 5.1.2 Started.
- 另一个 shell 窗口中，登录一个DataStore
$ ttisql tt_test
- 再起一个shell 窗口中，强制停止TimesTen Daemon。模拟TimesTen的异常终止。
$ ttdaemonadmin -stop -force
- 回到snmp的监听终端，将看到捕捉到的信息
# /usr/sbin/snmptrapd -f -Lo -M /home/tt705/TimesTen/tt705/mibs/TimesTen-MIB.txt

- 再次启动TimesTen Daemon
$ ttdaemonadmin –start
- 回到snmp的监听终端，将看到捕捉到的信息

TimesTen预定义了一些可以被监控的信息，比如内存耗尽，Agent没起来等等。你还可以在MIB文件中定义需要监控的其它信息。
