Syntax
threshold dns-lookup-failure
default
Configures this command with the default threshold setting.
Default: 90 percent. It is the same for both high and low thresholds.
Default: 90 percent. It is the same for both high and low thresholds.
high_thresh
Default: 90 percent
Specifies the high threshold for percentage of total DNS lookup failures. When the percentage of total
failures meets or exceeds the high threshold at the end of the polling interval, an alert or alarm is generated.
Specifies the high threshold for percentage of total DNS lookup failures. When the percentage of total
failures meets or exceeds the high threshold at the end of the polling interval, an alert or alarm is generated.
high_thresh
is an integer value from 0 through 100. When configured to 0 the threshold is disabled.
clear low_thresh
Default: 90 percent
Specifies the low threshold for percentage of total DNS lookup failures. When the percentage of total failures
goes below the low threshold within the polling interval, a clear alarm is generated.
Specifies the low threshold for percentage of total DNS lookup failures. When the percentage of total failures
goes below the low threshold within the polling interval, a clear alarm is generated.
low_thresh
is an integer value from 0 through 100. When configured to 0 the threshold is disabled.
Important:
This value is ignored for the Alert model. In addition, if this value is not configured for the Alarm
model, the system assumes it is identical to the low threshold.
Usage
Use this command to configure thresholds for the percentage of total DNS lookup failures. Note that this
threshold applies to both IPv4 and IPv6 DNS entries.
Alerts or alarms are triggered based on the following rules:
threshold applies to both IPv4 and IPv6 DNS entries.
Alerts or alarms are triggered based on the following rules:
Enter condition: Actual percentage of total DNS lookup failures is greater than or equal to the
specified percentage of total DNS lookup failures.
