Traceroute output required to be saved on text file via Event Manager

[Netmart]

Hello,

I set up the following event script; its purpose is to run a ping and traceroute and save its output on text file, if a specific syslog message is triggered: "%TRACK-6-STATE: 16 ip sla 16 reachability Up -> Down"

 event manager applet Test

  event syslog pattern "%TRACK-6-STATE: 16 ip sla 16 reachability Up -> Down"

  action 1.0 cli command "enable"

  action 2.0 cli command "ping 8.8.8.8   source vlan 10 | append bootflash:/Test.txt"

  action 2.1 cli command "traceroute 8.8.8.8    | append bootflash:/test"

  action 2.2 cli command "exit"

Based on the syslog messages and event manager history, the event is triggered, but no textfile is stored on bootflash.

Model is WS-C4500X-3, Version 03.06.07.E

I would appreciate any advise on this issue.

Thanks,

Our implementation doesn't have the "/". Try removing that. Not sure if you want to separate files or if the capital T is a typo or non-capitalized t is.
Also you can try debugging event manager cli actions.

Hello Larry,

Thank you for your reply.

I followed you advise, but unfortunately without any progress.

I successfully ran another simply EEM script:

 event manager applet show-clock

  event timer watchdog name timer time 30

  action 0.25 cli command "enable"

  action 0.5  cli command "show clock | append bootflash:/clock.txt"

  action 1.0  cli command "exit"

 !

48490  -rw-         175  Dec 30 2018 17:18:50 -05:00  clock.txt

And it was working fine.

Apparently, there is an issue with the cli traceroute command in association with "append":

while the show commands seems to support the "append" option, it seems not to be the case with commands, such as traceroute or ping:

RTR#show clock | append ?
bootflash: Uniform Resource Locator
cat4000_flash: Uniform Resource Locator
ftp: Uniform Resource Locator
http: Uniform Resource Locator
:

RTR#traceroute 8.8.8.8 | ?
% Unrecognized command

Therefore, I was wondering on what type of  Cisco device/IOS your EEM scripts are running?

Thanks,

.

Hi,

We run ours on 4300/4400 series and ASR1000 series routers.  Example below.

event manager applet EMAIL-DOWN authorization bypass
 event track 11 state down
 trigger delay 10
 action 1.0 cli command "enable"
 action 2.0 cli command "terminal length 0"
 action 2.5 cli command "del /force flash:output.txt"
 action 3.0 cli command "sh ip sla stat 11 | redirect bootflash:output.txt"
 action 3.1 cli command "sh ip sla stat 991 | append bootflash:output.txt"
 action 4.0 cli command "sh ip route x.x.x.x | append bootflash:output.txt"
 action 4.1 cli command "sh ip route x.x.x.x | append bootflash:output.txt"
 action 5.0 cli command "more flash:output.txt"
 action 6.0 mail server "x.x.x.x" to "e-maill address" from "sending email address" subject "subject" body "$_cli_result" source-address x.x.x.x
 action 7.0 cli command "del /force flash:output.txt"
 action 8.0 cli command "conf t"
 action 9.0 cli command "no track 11 ip sla 11"

Thank you Larry.

Show commands seems to be supported in association with "pipe append" while commands like traceroute and ping seem not to be provided in Cisco IOS XE; please see debug below.

Hence, I assume that I have to create a TCL script in order to capture the traceroute output on text file.

I found a similar discussion about TCLscripts at  https://community.cisco.com/t5/network-management/tcl-script-for-traceroute/td-p/3002966.

Ahh, makes sense.

[Samuel T Mathai]

did you make this work ? 

If its working could you please share the script ?
