EEM Applet PUTS Action BUG?

baldy · ‎08-19-2018

I have made a very simple eem applet to monitor some IP SLA entries in near real time -

!
event manager applet AUTO_SLA
 event timer watchdog time 3
 action 1.0 cli command "en"
 action 2.0 cli command "term len 500"
 action 3.0 cli command "show ip sla sum | i icmp"
 action 4.0 puts "\n$_cli_result\n"
 exit
!

The output from this as seen on the console looks like this -

IOU1#
*Aug 19 14:13:09.081: %HA_EM-6-LOG: AUTO_SLA:
*1           icmp-echo   11.1.1.1          RTT=4       OK          2 seconds ago
*2           icmp-echo   12.1.1.1          RTT=1       OK          2 seconds ago
*3           icmp-echo   13.1.1.1          RTT=1       OK          2 seconds ago
*4           icmp-echo   14.1.1.1          RTT=1       OK          2 seconds ago
*5           icmp-echo   15.1.1.1          RTT=1       OK          2 seconds ago
*6           icmp-echo   16.1.1.1          RTT=5       OK          2 seconds ago
*7           icmp-echo   17.1.1.1          RTT=1       OK          2 seconds ago

IOU1#*8           icmp-echo   18.1.1.1          RTT=1       OK          2 seconds ago
IOU1#

i.e. the output has a prompt injected into the middle of it.

The output that appears in the log looks like this

IOU1#
*Aug 19 14:14:18.153: %HA_EM-6-LOG: AUTO_SLA:
*1           icmp-echo   11.1.1.1          RTT=5       OK          2 seconds ago
*2           icmp-echo   12.1.1.1          RTT=1       OK          2 seconds ago
*3           icmp-echo   13.1.1.1          RTT=1       OK          2 seconds ago
*4           icmp-echo   14.1.1.1          RTT=1       OK          2 seconds ago
*5           icmp-echo   15.1.1.1          RTT=1       OK          2 seconds ago
*6           icmp-echo   16.1.1.1          RTT=5       OK          2 seconds ago
*7           icmp-echo   17.1.1.1          RTT=1       OK          2 seconds ago
*8           icmp-echo   18.1.1.1          RTT=1       OK          2 seconds ago
IOU1#

I have tried this on IOS 15.0, 15.2 and 15.4 and on IOU 15, all produce the same error on the output.

Any ideas?

Hi, can you try

action 4.0 puts "\n$_cli_result"

or

action 4.0 puts "\n"

action 4.1 puts "$_cli_result"

action 4.2 puts "\n"

or

test \r option instead of \n

Let me know.

Regards.

I'm running this on IOU and I have exactly the same problem. Output from a single puts action is broken after line 8 by the system prompt, after approximately half a second the remaining output is completed.
