EEM - Email the CLI output from router

This example shows how to quickly send the logs and configuration to TAC easily with EEM.

1. Configure the following required email related EEM environment variables:
event manager environment _email_server 1.2.3.4
event manager environment _email_from panda@pandaeatsbamboo.com
event manager environment _email_to attach@cisco.com

2. Configure the following EEM Applet named “sendtech”:
event manager applet sendtech
event none
action 1.1 cli command "enable"
action 1.2 cli command "del /force flash:show_tech"
action 1.3 cli command "show tech | append flash:show_tech"
action 1.4 cli command "show ip route | append flash:show_tech"
action 1.5 cli command "show ip interface brief | append flash:show_tech"
action 1.6 cli command "more flash:show_tech"
action 1.7 syslog msg "Sending show tech..."
action 1.8 mail server $_email_server to $_email_to from $_email_from subject " Show Tech Output (SR99999) " body "$_cli_result"
action 1.9 syslog msg "Show tech sent!"

Explanation of EEM Applet:
event manager applet sendtech ! registers applet with the name ‘sendtech’
event none  ! specifies the event which will trigger this applet – in this case, the applet will be triggered manually


3. Verify that the EEM applet has been registered and that the environment variables have been set correctly:

R3#show event manager policy registered
No. Class Type Event Type Trap Time Registered Name
1 applet user none Off Sat Mar 16 19:39:39 2002 sendtech
policyname {sendtech} sync {yes}
maxrun 20.000
action 1.1 cli command "enable"
action 1.2 cli command "del /force flash:show_tech"
action 1.3 cli command "show tech | append flash:show_tech"
action 1.4 cli command "show ip route | append flash:show_tech"
action 1.5 cli command "show ip interface brief | append flash:show_tech"
action 1.6 cli command "more flash:show_tech"
action 1.7 syslog msg "Sending show tech.."
action 1.8 mail server "$_email_server" to "$_email_to" from "$_email_from" subject "Show Tech Output (SR12345)" body "$_cli_result"
action 1.9 syslog msg "Show tech sent!"

R3#show event manager env all
No. Name Value
1 _email_server 1.2.3.4
2 _email_from panda@pandaeatsbamboo.com
3 _email_to attach@cisco.com

4. Manually trigger the script by issuing the command “event manager run sendtech”:

R3#event manager run sendtech
*May 19 20:16:46.440: %HA_EM-6-LOG: sendtech: Sending show tech...
*May 19 20:16:46.801: %HA_EM-6-LOG: sendtech: Show tech sent!
