+### Script to parse cfddns.sh log file and display important information
+###
+### Levels:
+### Levels are defined in this script as 0-4, 5 & 5+
+### Levels 0-4 (same): Basic information reporting
+###    Reports only critical information such as errors, update successes and ###    failures.
+### Level 5: Recommended information reporting level
+###    Adds informational messages such as the hostnames being updated and the ###    IP address being used for that update.
+### Level 5+ (same): Verbose logging
+###    This will just reprint the entire log.  This should only be used when ###    checking the actual logfile is not possible or you prefer looking at it ###    via Logwatch for some reason.  Note: ANSI colouring is removed by this ###    script to faciliate Logwatch conversion to HTML.  Therefore, viewing
+###    that actual log file is highly recommended instead of via this level of
+###    reporting in Logwatch.
+
+
+### Create temporary file for assembling log entries
+cfddnsTmpFile=$(mktemp -p "${LOGWATCH_TEMP_DIR}")
+
+### Assemble the temp file according to desired Logwatch detail level
+if [ "$LOGWATCH_DETAIL_LEVEL" -lt 5 ]; then
+    # get error, success and status messages
+    { grep '\-- \[ERROR\]' ; grep '\-- \[SUCCESS\]' ; \
+        grep '\-- \[STATUS\]' ; } >> "$cfddnsTmpFile"    
+elif [ "$LOGWATCH_DETAIL_LEVEL" -eq 5 ]; then
+    # get error, success, status and info messages
+    { grep '\-- \[ERROR\]' ; grep '\-- \[SUCCESS\]' ; \
+        grep '\-- \[STATUS\]' ; grep '\-- \[INFO\]' ; } >> "$cfddnsTmpFile"    
+elif [ "$LOGWATCH_DETAIL_LEVEL" -gt 5 ]; then
+    cat
+fi
+
+### Strip ANSI escape codes and sort entries according to timestamps
+sed -e 's,\x1B\[[0-9;]*[a-zA-Z],,g' "${cfddnsTmpFile}" | sort -n
+
+### Clean-up and exit
+rm -f "${cfddnsTmpFile}" > /dev/null 2>&1
+exit 0
