Adding/deleting monitor sinks
Every monitor must have at least one sink, and may have multiple sinks. There are two types of sink:
About this task
console - Sends output to metro node management server console.
file - Sends output to the specified file.
Adding a console sink
Use the monitor add-console-sink command to add a console sink to an existing monitor.

Console monitors display the selected statistics on the metro node Management Console, interrupting any other input/output
to/from the console. Refer to Enabling/disabling sinks for the command to disable a console sink.
The default format for console sinks is ‘table’.
To add a console sink with output formatted as table (the default output format):
VPlexcli:/> monitor add-console-sink --monitor Director-2-1-B_TestMonitorNavigate to the
monitor context and use the ll console command to display the sink:
VPlexcli:/> cd monitoring/directors/director-2-1-B/monitors/director-2-1-B_TestMonitor/
sinks
VPlexcli:/monitoring/directors/Director-2-1-B/monitors/Director-2-1-B_TestMonitor/sinks>
