ZED will log zevents summaries to the syslog, however the log entries tend to drop event details that can be useful for diagnosis. This is especially true for ereport events, like io, checksum, and delay. Update the all-syslog.sh script to log additional event information. Add an optional config option, ZED_SYSLOG_DISPLAY_GUIDS, to zed.rc for choosing GUIDs over names for pool and vdev. Change the default ZED_SYSLOG_SUBCLASS_EXCLUDE to exclude history_event events. These events tend to be frequent, convey no meaningful info, and are already logged in the zpool history.

README
Shell scripts are the recommended choice for ZEDLETs that mostly call other utilities and do relatively little data manipulation. Shell scripts MUST work on both bash and dash. Shell scripts MUST run cleanly through ShellCheck: http://www.shellcheck.net/ General functions reside in "zed-functions.sh". Use them where applicable. Additional references that may be of use: Google Shell Style Guide https://github.com/google/styleguide/blob/gh-pages/shell.xml Dash as /bin/sh https://wiki.ubuntu.com/DashAsBinSh Common shell script mistakes http://www.pixelbeat.org/programming/shell_script_mistakes.html Filenames and Pathnames in Shell: How to do it Correctly http://www.dwheeler.com/essays/filenames-in-shell.html Autoconf: Portable Shell Programming https://www.gnu.org/software/autoconf/manual/autoconf.html#Portable-Shell Please BE CONSISTENT with the existing style, check for errors, minimize dependencies where possible, try to be portable, and comment anything non-obvious.
