Performance monitoring using the CLI
The CLI supports current load monitoring, long term load monitoring, object base monitoring, and troubleshooting monitoring.
The CLI collects and displays performance statistics using:
monitors - Gather the specified statistic from the specified target at the specified interval.
monitor sinks - Direct the output to the desired destination. Monitor sinks include the console, a file, or a combination of the
two.
Use two pre-defined perpetual monitors for each director to collect information to diagnose common problems.
Use the CLI to create a toolbox of custom monitors to operate under varying conditions including debugging, capacity planning,
and workload characterization. For example:
The Dell EMC Administration Guide for metro node describes the procedure for monitoring metro node performance using the
CLI.
Notification
Events provide information about changes happening to the system, which also indicates that there is a problem with the
system. Alerts are events that require attention by the system administrator or user. Most alerts indicate that there is a problem
with the system that must be rectified to attain the best performance from the system.
The metro node notifications system displays live and historical alerts for platform, hardware (Both iDRAC and metro node
Monitor alerts) in the Notification pane that requires user attention and helps to monitor the state of the various components,
triage, and troubleshooting issues.
Notification features also allows to send alert notifications to a specified email or SMTP server. To configure SMTP server, see
System Configuration guide.
