Health Check - ADIC Scalar 100 User Manual

heartbeat. However, it does attempt to notify a Client when a ADIC Gateway fails
to respond.
Heartbeat failures are assigned event codes and notifications are sent to the
Client where possible. Heartbeat events are not logged in the event log because
SNMP traps are not issued (traps can only come from a ADIC Gateway). The
Default Trap Thresholds column at Table 8-2 on page 161 shows the threshold
settings that apply to specific event codes.

Health Check

The Health Check function provides a method to periodically determine the
operational state of a ADIC Gateway and its attached interfaces and devices.
When the Health Check is disabled, the ADIC Gateway performs no periodic
checks beyond monitoring environmental status lines, which indicate power
supply and temperature conditions.
The Health Check function posts SNMP traps, when required, to convey status
information to the ADIC Management Console. The ADIC Gateway broadcasts
SNMP traps on the local IP network segment. In addition, specific addresses may
be configured to send directed SNMP traps to host systems located on other
subnets. Routing information must be set-up for traps to be directed to a different
subnet. The ADIC Management Console server automatically registers itself as a
trap recipient when it connects to a ADIC Gateway.
