From Junos Space
Network Management Platform Release 16.1R1 onward, you can configure
log levels for JBoss and OpenNMS logs in Junos Space from the Administration
workspace in the Junos Space Platform UI. Junos
Space Platform enables you to configure log levels for the JBoss and
OpenNMS logs by using the Log Configuration page of the Space Troubleshooting
task group. When you configure a particular log level, log messages
for the selected severity and all higher severities are recorded.
You must be assigned the System Administrator role to configure
logs from the Log Configuration page.
To configure the JBoss and OpenNMS logs from the Junos
Space Platform UI:
- On the Junos Space Platform UI, select Administration > Space Troubleshooting > Log Configuration.
The Log Configuration page is displayed.
- Perform one of the following actions to configure the
JBoss or OpenNMS logs, respectively:
Click the JBoss Logs tab.
The log handlers configured in JBoss are listed on the page.
The corresponding log filenames and log levels are also displayed
in a tabular format. The Log Level column displays the existing log
level for each log.
Click the OpenNMS Logs tab.
The log handlers configured in OpenNMS are listed on the page.
The corresponding log filenames and log levels are also displayed
in a tabular format. The Log Level column displays the existing log
level for each log.
For more information about log files in Junos Space Platform,
see Junos Space Network Management Platform
Log Files Overview.
- Click the Log Level field of the log file for
which you want to configure the log level.
- Click the down arrow to select the log level from the
list.
When you select a particular log level, log messages for the
selected severity and all higher severities are recorded. For example,
if you select DEBUG as the log level, log messages for severity DEBUG, INFO, WARN, and FATAL are recorded in the log file for which you configured the log level.
If you select ALL, all log messages are recorded in the log file.
See Table 1 for more information
about the log levels that you can select.
- Click Update to save the change.
Repeat Step 2 through Step 5 to modify log levels for other
JBoss and OpenNMS logs listed on the page.
- (Optional) Select or clear the check box in the Enable/Disable column to enable or disable logging for the corresponding log file.
By default, logging for all JBoss and OpenNMS log files is enabled,
unless it is disabled from the Junos Space CLI, and the default log
level is WARN.
If you select the check box, logging is enabled and the log
level is set at the WARN level.
- Click Save to save all changes after you finish
specifying the log levels.
An audit log entry is added when you modify the log level of
any log file.
Table 1 lists the
various log levels that can be configured for JBoss and OpenNMS logs.
