This section provides an overview of tracing and information about the various trace levels
in Evweb. This section also describes administrative tasks such as
enabling, modifying, and disabling tracing.

Overview |
 |
Tracing is an error logging and reporting facility.
You can use this facility to log information about problems encountered
while using Evweb. All information about errors is logged in sfm.log. The default location of the sfm.log file is /var/opt/sfm/log/sfm.log. You
can send these log files to the HP support center whenever you encounter
a problem.
Following is a sample of the information logged
in sfm.log.
01/04/06 06:50:08 EVMAN_COMMANDS
ERROR 1069627450 1 Subscription with this name already exist, Please
choose different name and try again.
Table 5-4 describes
the various fields included in the sfm.log file.
Table 5-4 Entries in sfm.log
| Field | Description |
|---|
Date | Displays the date when the message was logged in
the sfm.log file. |
Time | Displays the time when the message was logged in
the sfm.log file. |
Module Name | Displays the name of the module or the providers
that logged the message in the sfm.log file,
for example, Evweb_CLI, FMDProviders. |
Severity | Displays the severity of the message logged in the sfm.log file. |
Process ID | Displays the 10-digit process ID. |
Thread ID | Displays the thread ID. |
Message | Displays the text message. |
To change the default location of the sfm.log file, you must configure the /var/opt/sfm/conf/FMLoggerConfig.xml file.
You can enable tracing for an Evweb session. A
session is the duration between a login and a logout. When you enable
tracing, make sure that you set a trace level.
Table 5-5 describes the trace levels in Evweb.
Table 5-5 Trace Levels in Evweb
| Trace Level | Description |
|---|
| 1-Critical | The system logs only those situations
in Evweb that cause major failures. Example: The database
server is not functioning properly or is down. |
| 2-Error | The system logs those situations
that cause an error. Example: There is more than one name.
Evweb accepts only one name. Critical situations are also
logged at the Error trace level. |
| 3-Warning | The system logs situations that
result in warning messages. Example: A warning is generated
when the default setting is modified. Both critical and
error situations are logged at the Warning trace level. |
| 4-Information | The system logs situations that
result in information messages. Example: An information
is generated when a non-administrator attempts to perform a task that
can be performed only by an administrator. Critical, error,
and warning situations are logged at the Information trace level. |
Evweb logs traces for a session for the set trace
level. At the end of a session, tracing is automatically disabled.
In an active session, the trace level remains valid until you modify
it.
The traces for a session are also logged in the samlog.log. The path to the samlog.log file is /var/sam/log/samlog.log. From the
GUI, you can access the samlog.log file from HP SMH home page -> Logs -> Samlog. The samlog.log file contains all the administrative commands executed on a system.
The errors generated during the execution of these administrative
commands are also stored in the samlog.log file.

However, non-administrators can view the trace files. |
