<h3>Core client logging and error output</h3>
|
||
|
|
<p>
|
||
|
|
The core client writes error messages to stderr.
|
||
|
|
This mechanism is reserved for serious problems,
|
||
|
|
i.e. those that reflect bugs in the core client program
|
||
|
|
or conditions that require user intervention.
|
||
|
|
|
||
|
|
<p>
|
||
|
|
In addition, the core client can write a variety of "logging"
|
||
|
|
information to stdout.
|
||
|
|
|
||
|
|
The logging options are read from a file <b>log_flags.xml</b>.
|
||
|
|
This file has the following format:
|
||
|
|
|
||
|
|
<pre>
|
||
|
|
<log_flags>
|
||
|
|
[ flags ]

||
|
|
</log_flags>

|
</pre>
|

<h3>Application error output</h3>
|
||
|
|
<p>
|
||
|
|
The stderr of applications is automatically directed to a file.
|
||
|
|
The contents of this file are returned to the scheduling server
|
||
|
|
and stored in the database.
