Network (LAN) Monitoring

F u n c t i o n s

The network (LAN) monitoring function reports an alert to record and NEC ESMPRO Manager of the detection

information to a syslog at time beyond the threshold that a destruction packet and the error packet that

occurred during a monitoring interval were set. After having detected abnormality, it does not have any

problem when it recover immediately, but disperse with the load of confirmation and the network of the

network environment that the hardware included when time and the abnormality that were not restored occur

frequently.

Because the network (LAN) monitoring function judges an error from a ratio for transmission and reception

number of packets caused during a monitoring interval, the network (LAN) monitoring function sometimes

detects it by temporary network load. Therefore default of the monitoring setting is invalid NEC ESMPRO

Agent Ver.4.3 or later because it cannot be said that certainty is high for the monitoring of the obstacle of LAN.

- When you validate network (LAN) monitoring, start with the setting change of ESMlan.

# /sbin/chkconfig --level 35 ESMlan on

# /etc/init.d/ESMlan start

- When you invalidate network (LAN) monitoring, stop with the setting change of ESMlan.

# /sbin/chkconfig ESMlan off

# /etc/init.d/ESMlan stop
