This selection from the main Platform Administration view lets you “tune” the amount and content of the platform daemon output (View Daemon Output). You can do this by changing the log filter settings of the various daemon processes (Figure 58).
By default, all daemon processes have a “Message” log filter level, and include the following:
-
niagarad — Log for the platform daemon (niagarad) process, with “high level” entries like “
niagarad starting, “baja home = ...”, “niagarad stopping”. -
webserver — Log for HTTP server for incoming platform client connections. Entries are often generic, before the daemon hands off to the appropriate platform servlet.
-
stationregistry — Log for platform daemon management of stations, including startup, shutdown, and watchdog actions.
-
logfilter — Logs changes to daemon log states, meaning it tracks changes made in this dialog.
-
reboot — Log for the reboot servlet, one of the servlets the platform daemon manages.
-
updatedaemon — Log for handling Workbench requests for current platform daemon configuration, used mainly by Platform Administration view.
-
file — Logs requests made to the platform daemon’s file servlet, used in platform views like the File Transfer Client, Commissioning Wizard, Software Manager, Station Copier, and so on. Many different things can print on this log, like “
request for file xxx”, or “wrote file xxx”. -
qnxosupdate — Log for the OS upgrade servlet created by the platform daemon. Workbench uses this servlet to upgrade the QNX OS in the host JACE when using the Commissioning Wizard or Distribution File Installer. Entries here can reflect a problem when updating the QNX OS, such as “
os crc isn’t right”, or “waitpid when launching osupdate command failed”. -
appOut — Log for the thread managing buffers associated with station output, making that output visible in the Application Director view. Entries may reflect buffer size changes (available in Application Director interface), or if a problem occurs streaming the output to Workbench.
For any item, use the Filter Setting drop-down to select one of the following:
-
Trace
Returns all message activity (verbose). This includes all transactional messages, which may result in too many messages to be useful. Be careful using Trace!
-
Message
(Default) Returns informational “MESSAGE”s, plus all “ERROR” and “WARNING” types.
-
Warning
Returns only “ERROR” and “WARNING” type messages (no informational “MESSAGE”s).
-
Error
Returns only “ERROR” type messages (no “WARNING” or informational “MESSAGE”s).
