Question: Where are the Alarm and Event Log files stored?
Answer: Alarm and Event tables, as well as Trend Historian tables,
are stored in the \etc\data directory under the FEPHOME directory,
as specified by the system environment settings (this is typically
C:\COMPASS\etc\data).
Question: How can I view Alarm and Event information from
other nodes with the Alarm & Event Viewer?
Answer: There are several ways to do this. You can invoke the
Alarm & Event Viewer with the host to which you want to connect as
a parameter, as in: fepaem -h remotehost (remotehost is the
name or IP address of the remote host for which you wish to monitor
alarms and events). This is a fairly costly method to network
resources.
If you wish to view only alarm data from the Alarm Viewer, you can
configure the remote machine as a remote host through Runtime
Config/System Configuration/Runtime Nodes on the Compass
Administrator. With the Node Filter in the Alarm Viewer you can
specifically query Alarms from any one configured remote host node,
the local node, or all nodes. This is significantly less costly on
network resources than the first option.
To view alarms and events in the Event Viewer from other nodes,
those nodes must be configured to send their data to the node to
which the Alarm & Event Viewer is connected. By default, the
viewer is connected to the local node. You can configure a node to
send alarm and event log records from Runtime Config/System
Configuration/Event Log Parameters/Supplemental Event Log
Locations. In systems with many nodes, it is common practice to
designate one node as a collector of alarm and event log information.
This is slightly less costly on network resources than the other
options, but the node that receives log records must have enough disk
space to hold a reasonable amount of log history to be useful. If
nodes are separated by slow links (intercontinental and satellite links
usually fall into this category), you must replicate the nodes to be
able to view alarm and event data across the network..
