TCL value $arr_einfo(msg) empty

[peraocompany]

Hello i have some test tcl script for cisco router:

# script.tcl test
::cisco::eem::event_register_syslog tag 1 pattern ".*SYS-5-CONFIG_I: Configured from console.*" occurs 1


::cisco::eem::trigger {
::cisco::eem::correlate event 1
::cisco::eem::attribute tag 1 occurs 1
}

namespace import ::cisco::eem::*
namespace import ::cisco::lib::* 

set hostname [info hostname]
array set arr_einfo [event_reqinfo]
puts "Syslog message is $arr_einfo(msg)"

i call tcl script: event manager policy script.tcl

event manager directory user policy "flash:/"

in this case I have all time blank cli message: Syslog message is (without arr_einfo(msg))
Can someone help please? Thank you.

This variable should not be blank.  However, it may start with a newline, which could give the impression of being blank.  Change your last line to:

puts "Syslog message is **$arr_einfo(msg)**"

And you'll see the asterisks to let you know if the variable is truly empty.
