Several standard Linux tools can be used to monitor the EDEX processes, and for the purposes of this document and the Unidata AWIPS Training Workshop, it is assumed that all are available and that the user has some knowledge of how they are used. Regardless, this document includes the full command syntax that can be copy and pasted from the document to the terminal.
-
ps - Display information about specific processes
ps aux | grep edex -
cat - Used to display a text file in a terminal
cat /awips2/ldm/etc/pqact.conf -
tail - Used to provide a dynamic picture of process logs
tail -f /awips2/ldm/logs/ldmd.conf -
grep - Used to filter content of process logs; used to filter output of other tools
grep edexBridge /awips2/ldm/etc/ldmd.conf -
