Remote monitoring
Introduction
Remote Monitoring (RMON) allows network devices to exchange network monitoring data.
RMON performs the following major functions:
• Gathers cumulative statistics for Ethernet interfaces
• Tracks a history of statistics for Ethernet interfaces
• Creates and triggers alarms for user-defined events
Overview
The RMON MIB provides an interface between the RMON agent on the HP ProLiant BL p-Class GbE2
Interconnect Switch and an RMON management application. The RMON MIB is described in RFC 1757.
The RMON standard defines objects that are suitable for the management of Ethernet networks. The RMON
agent continuously collects statistics and proactively monitors switch performance. RMON allows you to monitor
traffic flowing through the GbE2 Interconnect Switch.
The GbE2 Interconnect Switch supports the following RMON Groups, as described in RFC 1757:
• Group 1: Statistics
• Group 2: History
• Group 3: Alarms
• Group 9: Events
RMON group 1—statistics
The GbE2 supports collection of Ethernet statistics as outlined in the RMON statistics MIB, in reference to
etherStatsTable. You can enable RMON statistics on a per-port basis, and you can view them using the
/stat/port x/rmon command. RMON statistics are sampled every second, and new data overwrites any old
data on a given port.
NOTE: RMON port statistics must be enabled for the port before you can view RMON statistics.
Configuring RMON group 1 (CLI example)
1. Enable RMON on each port where you wish to collect RMON statistics.
>> /cfg/port 23/rmon (Select Port 23 RMON)
>> Port 23 RMON# ena (Enable RMON)
>> Port 23 RMON# apply (Make your changes active)
>> Port 23 RMON# save (Save for restore after
reboot)
