eem applet why always more output lines ?

[edomatic007cisco]

Hi guys,

I need some help here, i am troubled by the way my eem applet always seems to add 2 lines to the output of the following applet outcome:

R1(config)#event manager applet test
R1(config-applet)#event none
R1(config-applet)#action 0010 cli command "enable"
R1(config-applet)#action 0011 puts ""
R1(config-applet)#action 0012 cli command "sh int desc | i 2000"
R1(config-applet)#action 0013 puts "$_cli_result"
R1(config-applet)#exit
R1(config)#end

R1#event manager run test
sh run int desc | i 2000
Fa0/0 up up --- TO BOKO657 & BHKG6568 VTI 2000
R1#

R1#sh int desc | i 2000
Fa0/0 up up --- TO BOKO657 & BHKG6568 VTI 2000
R1#---without eem i am right back at the prompt so only one line is the output of the sh int desc command

but when the applet is ran, i see 2 extra lines, one is the 'empty' router prompt line R1# and then there is another blank line following it and i want to get only the match line containing "2000"...how do i do this??

Hello,

put the keyword 'nonewline' before the 'puts':

event manager applet test
event none
action 0010 cli command "enable"
action 0011 puts ""
action 0012 cli command "sh int desc | i 2000"
action 0013 puts nonewline "$_cli_result"

Hi Georg,

Thanks for replying, that got one line out but, the "R1# prompt line" still is there, strange..is there an "enter" or carriage return hidden or something? How can i avoid that extra 'blank line' that is left as to only get the description line only as the output

R1(config-applet)#action 0013 puts nonewline "$_cli_result"
R1(config-applet)#end

Hello,

when you run the applet, do you get the R1# prompt twice ?

R1#event manager run test
Fa0/0 up up --- VTI 2000
R1#
R1#here its stopped

I only get it once. Which IOS are you running, and on which device ?

Hi Georg,

note i removed hostname, this one still prints one extra line before returning to prompt

#conf t
Enter configuration commands, one per line. End with CNTL/Z.
(config)#event manager applet test
(config-applet)#event none
(config-applet)#action 0010 cli command "enable"
(config-applet)#action 0012 cli command "sh int desc | i 2000"
(config-applet)#action 0013 puts nonewline "$_cli_result"
(config-applet)#action 0014 exit
(config-applet)#end
event manager run test

Hello,

odd, since I don't get that when I run the applet. The only difference is that I do not have action:

action 0014 exit

Try to run the applet without that line:

event manager applet test
event none
action 0010 cli command "enable"
action 0012 cli command "sh int desc | i 2000"
action 0013 puts nonewline "$_cli_result"

Hi Georg,

look i tried it on another chassis (without the exit command this time) but same result, i still got an extra line there (the router prompt line) :

event manager applet test
event none
action 0010 cli command "enable"
action 0011 puts ""
action 0012 cli command "sh int desc | i DSL"
action 0013 puts nonewline "$_cli_result"
!
end

router#event manager run test

router#here the applet stopped
router#sh int desc | i DSL

router#here it stops when running the command without eem applet

Hello,

odd, as I don't get that extra line. I cannot test this on a real device right now, but try to add the 'end' action:

event manager applet test
event none
action 0010 cli command "enable"
action 0012 cli command "sh int desc | i 2000"
action 0013 puts nonewline "$_cli_result"
action 0014 end

Hi Georg,

When i do it like that the applet does not register due to:

*Nov 22 16:18:15.103: %HA_EM-6-FMPD_EEM_CONFIG: test: "end" action found outside of conditional block
