Hi, I am trying to capture some custom information using a simple shell script. I am trying below but getting an error. Below is my parser, it works fine without the line that has custom_script_output. How do I get this to work? parser p_cr_syslog { # Convert the LEVEL field to uppercase. map-value-pairs(pair("jcnr.header.logLevel", "$(uppercase $LEVEL)")); map-value-pairs(pair("jc.header.custom_script_output", "$(script("/path/to/script.sh"))")); syslog-parser(flags(syslog-protocol) template("${MESSAGE}")); map-value-pairs( pair("jc.header.nodeName", "$HOST") pair("jc.header.eventDateTime", "$R_ISODATE") pair("jc.header.notificationType", "$MSGID") pair("jc.body", "$MSG") pair("jc.header.program", "$PROGRAM") ); # Log the output of the script. action { file { path "/var/log/syslog"; message "$jc.header.custom_script_output"; } } } Thanks in advance. -- Regards, Faisal
