Available for: Linux, Windows
The logger driver can be used to log events to a file. Two formats of the log file is supported. Either standard log file with a standard text string for each event on each line or in XML file format which can be read by VSCP works and further analyzed there.
Driver Linux: vscpl2_loggerdrv.so Driver Windows: vscpl2_loggerdrv.dll
The configuration string have the following format
See the table below for a description. Variables fetched from the daemon is used if they are available even if the configuration string specify a value.
|_path||string||Path to the logfile.|
|_rewrite||bool||Set to “true” to rewrite the file each time the driver is started. Set to “false” to append to file.|
|_vscpworksfmt||bool||If “true” VSCP works XML format will be used for the log file. This means that the file will be possible to read and further analyzed by VSCP Works. If “false” a standard text based format will be used.|
|_filter||string||Standard VSCP filter in string from. 1,0x0000,0x0006,ff:ff:ff:ff:ff:ff:ff:01:00:00:00:00:00:00:00:00 as priority,class,type,GUID|
|_mask||string||Standard VSCP mask in string form. 1,0x0000,0x0006,ff:ff:ff:ff:ff:ff:ff:01:00:00:00:00:00:00:00:00 as priority,class,type,GUID|
The full variable name is built from the name you give the driver (prefix before _variablename) in vscpd.conf. So in the examples below the driver have the name log1 and the full variable name for the _path variable will therefore be
If you have another diver and name it log2 it will therefore instead request variable log1_path.
If your driver name contains spaces, for example "name of driver" it will get a prefix that is "name_of_driver". Leading and trailing spaces will be removed.
<driver enable="true" > <name>log1</name> <path>/usr/local/lib/vscpl2_loggerdrv.so</path> <config>/tmp/vscp_level2.log</config> <guid>00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00</guid> </driver>
