Alert Management
Question Answer
Why is the Alert Log
for a managed system
empty when I receive
alerts and see them
displayed in the Alert
Logs view?
When IT Assistant receives an event with an IP address stored
in the event, IT Assistant resolves the event to a name
accordingly by using its database of discovered systems
(if instrumentation name resolution is preferred) or by using
DNS (if DNS resolution is preferred). SNMP traps and CIM
indications will always have an IP address to resolve from.
If the IP address is already resolved to a name, IT Assistant
does not attempt to resolve it again because this action could
lead to differences in the name stored in the event versus the
name under which IT Assistant discovered the system and sent
the event, if instrumentation name resolution is preferred in
IT Assistant. This issue may result in event actions not being
performed due to the selection of system names in the
Event Filters creation dialog that do not match the name
contained in the event.
In addition, all of the events received from that system may
not be displayed in that system's Alerts view in IT Assistant. To
avoid this behavior, it is recommended to choose DNS
resolution as the preferred resolution in IT Assistant if DNS or
WINS exist in the network environment in which IT Assistant
is performing discovery.
