After entering a date range, click the icon to request historical Alarm data. When the query is complete, click the icon to resume displaying real time Alarms.


All fields associated with Alarms are available to be included as columns in the table, but you can customize both which columns are displayed as well as the text in the header.

While all Alarms are recorded on the OAS Server, the Alarm Component can be configured to filter or include particular Alarms. If an Alarm is filtered out, it will not be displayed in the table.

GroupsA comma-delimited list of Groups to include
Network NodesA comma-delimted list of network nodes to include. If left blank, only Alarms triggered on the current server will be included. Network Nodes can be OAS Server IP addresses or domain names mapped to an OAS Server. If external servers are included, you can explicitly add localhost to the list to also include the current server
Priority RangeA numeric low and high value for Alarm Priorities to include

Color Scheme

Table row coloring is configurable, allowing you to set the foreground or text, as well as the background color. The Default color scheme is used for any Alarms not matching any of the other available states.
