Viewing health notifications with the xscmd utility

[Version 8.6 and later] You can view current event notifications, show event notification history, and set notification filters from the message center with the xscmd utility.

Before you begin

Configure your health notification hubs on your catalog servers. For more information, see Configuring the message center.
Start the xscmd utility and connect it to the catalog service domain. For more information, see Administering with the xscmd utility.

Procedure

Display the event notification history with the xscmd utility.
The output displays in a tabular format.
```
xscmd -c showNotificationHistory -cep hostname:port(,hostname:port)
```
Listen for new notifications.
```
xscmd -c listenForNotifications -cep hostname:port(,hostname:port) 
```
The output is in raw format and runs until you stop the command. You can write additional scripts to parse the output.
Enable filtering on all future log entries, including INFO, WARNING, and SEVERE log entries. By default, the message center & commands only show WARNING errors, SEVERE errors, and events. You can set the filter for all servers in the environment or a single server. This setting affects future results only.
```
xscmd -c setNotificationFilter -fs <regular expression>  [-server <servername>] 
```
Display the current notification filters for all the servers in your environment or a single server.
```
xscmd -c getNotificationFilter [-s servername]
```
