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.
This section addresses the following topics:
Tracing is a feature that enables you to log and report errors.
You can use tracing to log information about problems encountered
while using Evweb. In this document, this information is referred
to as trace records. The trace records are stored in the /var/opt/sfm/log/sfm.log file. You can send
the sfm.log file 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
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 and 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, modify, and disable tracing for an Evweb session.
A session is the duration between a login and a logout. At the end
of a session, tracing is automatically disabled. In an active session,
the trace level remains valid until you modify it.
Evweb provides the following trace levels in the descending
order of severity:
Table 5-5 describes the
trace levels in Evweb.
Table 5-5 Trace Levels
| 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 generate an error. Example: There is more than one
subscription name. Evweb accepts only one subscription 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
message 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. |
The default trace level is Warning. If you set tracing to a
particular severity level, all messages of that severity and above
are logged in the log file.
The administrative commands for creating, modifying, and deleting
subscriptions, and deleting events are stored in the /var/sam/log/samlog.log file. From
the GUI, you can access the samlog.log file from HP SMH home page -> Logs -> Samlog.
