Capture output sent to System.err.
| directive | meaning | default |
|---|---|---|
| path | output path for the stream | either path-format or path is required |
| path-format | the name of a file to write the log to, date format escape sequences are replaced with the current date and time | either path or path-format is required |
| timestamp | a timestamp in date format to use at the beginning of each log line. | no timestamp |
| rollover-period | how often to rollover the log. Specify a period in days (15D), weeks (2W), months (1M), or hours (1h) | none |
| rollover-size | maximum size of the file before a rollover occurs. Specify a size in bytes (50000), kb (128kb), or megabytes (10mb) | 1mb |
| archive-format | the format for the archive filename when a rollover occurs | path + ".%Y%m%d" or path + ".%Y%m%d.%H" if rollover-period < 1 day |
[edit] Environments
stderr-log can appear in any environment (i.e. within a server, host, or web-app).
Usage of the stderr-log overrides a previous usage in a containing environment. For example, specifying stderr-log as a child of a web-app causes a redirection of System.err for that web application only, and will override the System.err location in the enclosing host.
[edit] Examples
resin.conf configuration to capture all System.err output to log/stderr.log:
<resin xmlns="http://caucho.com/ns/resin" xmlns:resin="http://caucho.com/ns/resin/core"> <stderr-log path='/var/log/foo/stderr.log' rollover-period='1W'/> ...
host configuration to capture all System.err output within a host to log/stderr.log. Unless a web-app overrides with it's own stderr-log, all web-apps in the host will write to the same output file.
...
<host id='foo.com'>
<stderr-log path='/var/log/foo/stderr.log'
rollover-period='1W'/>
...
</host>
...
