configure debug-trace health-check
ExtremeWare 7.7 Command Reference Guide 1189
Default
The default level is 0.
Usage Guidelines
The
debug level
range is 0 to 5. Higher levels record more verbose messages. Higher levels also
record the messages recorded at lower levels.
Health-check debug messages apply to all resources tracked by health-check. The messages recorded
are in addition to messages you have configured for other features.
You can define a filter to limit the debug messages logged. Before you define a filter, you must
configure the debug level. To define a filter, you must do the following:
1 Specify a real or virtual IP address. You can specify both a real and virtual IP address in the same
command line. An IP address of 0.0.0.0 will match any IP address. Messages without associated IP
addresses are logged regardless of the filters you define.
2 Specify a port or service. A service of
wildcard
or a port of 0 will match any service or port number.
The filter limits the recorded messages to those concerning the IP addresses and services you specify. If
you do not configure a filter,
debug-trace
records messages at the debug level you specify for every
service on every IP address.
When you save your configuration, you also save your configured filter values.
Example
The following command enables level 2 debug-tracing:
configure debug-trace health-check 2
The following command then configures a filter for a specific server and service:
configure debug-trace health-check filter real 1.2.3.4 : http
This configuration logs health-check debug messages at levels 0, 1, and 2 for the following:
• Generic health-check messages
• ping-check for IP address 1.2.3.4
• tcp-port-check for IP 1.2.3.4 port 80 (HTTP)
• service-check for IP 1.2.3.4 port 80 (including any virtual servers that use SLB pool member 1.2.3.4
port 80)
Alternate Example
The following command enables level 2 debug-tracing:
configure debug-trace health-check 2
The following command configures a filter that provides all of the information in the preceding
example, and also logs service-checks specifically for the SLB virtual server (5.6.7.8 port 80) that
references SLB pool member 1.2.3.4 port 80:
configure debug-trace health-check filter real 1.2.3.4 : http virtual 5.6.7.8 : http
