[LDM #YYI-187309]: Removal of Syslog dependency

Hi Carissa,

> Here at NCEP we run LDM in a virtualized environment with a central syslog
> server that all LDM use. There has been occasion when the syslog system has
> gone done, and with it taken all of the LDM systems. From what it looks
> like, LDM 6.13 and greater removes all dependencies on syslog?  Is this true
> that all logging is now just done locally to the home/log path?

It's true. Beginning with LDM 6.13.0 the default logging mechanism no longer 
uses the system logging daemon for the reasons you saw. It's possible to build 
the LDM so that it uses the system logging daemon, however, by specifying the 
"--with-ulog" to the configure(1) script.

> My concern
> here now is performance, we also run most LDMs with verbose logging on.
> Have you seen any system capacity issues with verbose on writing to disk?

None whatsoever. Writing a log message to an open file is much, much faster 
than performing a pqact(1) "FILE" action with the "-close" option.

Having said that, please let me know immediately if you do encounter a 
performance issue.

Steve Emmerson
