Controlling Oracle VM Server for SPARC Logging Operations

Use the ldm set-logctl command to specify the fine-grained logging characteristics that control the messages written to the log. Note that you cannot disable the logging of fatal or warning messages. See the ldm(8) man page.

Example 18-6 Controlling Event Logging Operations

The following examples show ways in which to use the ldm set-logctl command:

Enable logging for notice messages, which indicate that an event requires user attention.
```
primary# ldm set-logctl notice=on
```
Specify the number of messages that the ldm list-history command outputs.

The following command sets the number to 20.
```
primary# ldm set-logctl history=20
```
Reset logging properties to the default values.
```
primary# ldm set-logctl defaults
```

Example 18-7 Logging Output

Use the ldm set-logctl command to specify the logging characteristics for Oracle VM Server for SPARC events to be written to the log.

The following command logs ldm commands:
```
primary# ldm set-logctl cmd=on
```
When you configure command logging, the following types of information are logged:
- The following entry is logged for an ldm list command:
```
cmd: ldm list
cmd: OK
```
- The following entry is logged for a badly formed ldm list command:
```
cmd: ldm list -x
cmd: USAGE
```
- The following entry is logged for an ldm list command that specifies a non-existent domain:
```
cmd: ldm list non-existent-domain-name
cmd: ERROR:
cmd: LDom "non-existent-domain-name" was not found
```

The following command logs ldm commands and command responses:

primary# ldm set-logctl cmd=resp

For example, when you issue the ldm list command, the following command information is logged:

cmd: ldm list
cmd: OK:
cmd: NAME             STATE      FLAGS   CONS    VCPU  MEMORY   UTIL  NORM  UPTIME
cmd: primary          active     -n-cv-  SP      16    9248M    0.8%  118d 3h
cmd: ldg1             active     -t----  5000    16    4G       6.2     %  2d 22h 24m
