Use Case Warning Threshold
%PMON-SLOT2-5-WARNING_THRESHOLD_REACHED_DOWNWARD: Invalid Words has reached warning threshold
in the downward direction (port fc2/18 [0x1091000], value = 5).
In the first polling interval, the errors triggered for the counter (Invalid Words) are 10, and have
reached the warning threshold value. A syslog is generated, indicating that the error count is increasing
(moving in the upward direction).
In the next polling interval, the error count decreases (moves in the downward direction), and a syslog
is generated, indicating that the error count has decreased (moving in the downward direction).
This example displays the syslog that is generated when the error count crosses the rising threshold value:
Syslog Generated When the Error Count Crosses the Rising Threshold Value
%PMON-SLOT2-4-WARNING_THRESHOLD_REACHED_UPWARD: Invalid Words has reached warning threshold
in the upward direction (port fc2/18 [0x1091000], value = 30).
%PMON-SLOT2-3-RISING_THRESHOLD_REACHED: Invalid Words has reached the rising threshold
(port=fc2/18 [0x1091000], value=30).
%SNMPD-3-ERROR: PMON: Rising Alarm Req for Invalid Words counter for port fc2/18(1091000),
value is 30 [event id 1 threshold 30 sample 2 object 4 fcIfInvalidTxWords]
%PMON-SLOT2-5-WARNING_THRESHOLD_REACHED_DOWNWARD: Invalid Words has reached warning threshold
in the downward direction (port fc2/18 [0x1091000], value = 3).
%PMON-SLOT2-5-FALLING_THRESHOLD_REACHED: Invalid Words has reached the falling threshold
(port=fc2/18 [0x1091000], value=0).
%SNMPD-3-ERROR: PMON: Falling Alarm Req for Invalid Words counter for port fc2/18(1091000),
value is 0 [event id 2 threshold 0 sample 2 object 4 fcIfInvalidTxWords]
This example displays the syslog generated when the error count is more than the warning threshold value
and less than the rising threshold value:
Syslog Generated When the Error Count is More than the Warning Threshold Value and Less than
the Rising Threshold Value
%PMON-SLOT2-4-WARNING_THRESHOLD_REACHED_UPWARD: Invalid Words has reached warning threshold
in the upward direction (port fc2/18 [0x1091000], value = 15).
%PMON-SLOT2-5-WARNING_THRESHOLD_REACHED_DOWNWARD: Invalid Words has reached warning threshold
in the downward direction (port fc2/18 [0x1091000], value = 3).
The errors generated for the counter (Invalid Words) are 30 when the counter has crossed both the warning
and rising threshold values. A syslog is generated when no further errors are triggered.
As there are no further errors in this poll interval, the consecutive polling interval will have no errors, and the
error count decreases (moves in downward direction) and reaches the falling threshold value, which is zero.
A syslog is generated for the falling threshold.
