Charts - Planet Networking & Communication WGSW-24010 User Manual

The page includes the following fields:
• Alarm Entry -- Indicates a specific alarm.
• Interface -- The interface for which RMON statistics are displayed.
• Counter Name -- The selected MIB variable.
• Counter Value -- B class=cBold origTag="Bold" cs="Bold"> The value of the selected MIB variable.
• Sample Type -- Specifies the sampling method for the selected variable and comparing the value against the
thresholds. The possible field values are:
• Delta -- Subtracts the last sampled value from the current value. The difference in the values is compared to the
threshold.
• Absolute -- Compares the values directly with the thresholds at the end of the sampling interval.
• Rising Threshold -- The rising counter value that triggers the rising threshold alarm. The rising threshold is
presented on top of the graph bars. Each monitored variable is designated a color.
• Rising /Falling Event -- The mechanism in which the alarms are reported -- LOG, TRAP, or a combination of
both. When LOG is selected, there is no saving mechanism either in the device or in the management system.
However, if the device is not being reset, it remains in the device LOG table. If TRAP is selected, an SNMP trap
is generated and reported via the trap □ general mechanism. The TRAP can be saved using the same
mechanism.
• Falling Threshold -- The falling counter value that triggers the falling threshold alarm. The falling threshold is
graphically presented on the bottom of the graph bars. Each monitored variable is designated a color.
• Startup Alarm -- The trigger that activates the alarm generation. Rising is defined by crossing the threshold
from a low-value threshold to a higher-value threshold.
• Interval (sec) -- Alarm interval time.
• Owner -- Device or user that defined the alarm.
• Remove -- When selected, removes an RMON Alarm.
