EEM Script for reload

[Felixsson1]

Hi,

I've made a EEM applet for reloading a Cisco router after certain part of message appears in syslog.

No.   Class    Type    Event Type   Trap    Time    Registered                          Name
1      applet    user     syslog          Off      Mon     Dec 19 07:21:21 2022     RELOAD
pattern {Text ABC123}
maxrun 20.000
action 1.0 cli command "enable"
action 2.0 cli command "reload"

1.) Why is the text in pattern shown with {} instead with " as I typed?

2.) Trap says it's "off".

3.) In the output below the applet process status is abort so my router never reloads. What I'm missing in the configuration?

Router2#sh event manager history events
No. Job Id Proc Status Time of Event Event Type Name
1 41 Actv abort Mon Dec19 07:24:27 2022 syslog applet: RELOAD
2 42 Actv abort Mon Dec19 07:25:40 2022 syslog applet: RELOAD
3 43 Actv abort Mon Dec19 07:26:52 2022 syslog applet: RELOAD
4 44 Actv abort Mon Dec19 07:28:05 2022 syslog applet: RELOAD
5 45 Actv abort Mon Dec19 07:29:17 2022 syslog applet: RELOAD
6 46 Actv abort Mon Dec19 07:30:30 2022 syslog applet: RELOAD
7 47 Actv abort Mon Dec19 07:31:43 2022 syslog applet: RELOAD
8 48 Actv abort Mon Dec19 07:32:55 2022 syslog applet: RELOAD
9 49 Actv abort Mon Dec19 07:34:08 2022 syslog applet: RELOAD
10 50 Actv abort Mon Dec19 07:35:20 2022 syslog applet: RELOAD

EDIT:

This works:

event syslog pattern ".*Unknown modem on SKU type C881G-4G-GA-K9.*"
trigger delay 2000
action 1 cli command "ena"
action 2 cli command "reload" pattern "confirm"
action 3 cli command "y"

what is the device model and IOS code running, can you post EEM Script :

event manager applet reload-device
maxrun 20.000
event syslog pattern "my message"
action 1.0 cli command "enable"
action 2.0 cli command "reload"

[MHM Cisco World]

can I see your config I will run lab test it 

[Felixsson1]

event manager applet SKU_RELOAD
event syslog pattern "Unknown modem on SKU type C881G-4G-GA-K9"
action 1.0 cli command "enable"
action 2.0 cli command "reload"

Syslog generates this messages:

Dec 19 07:04:14.346: %CISCO800-2-MODEM_UP: Cellular0 modem is now UP
Dec 19 07:04:34.361: %CELLWAN-4-MODEM_COMM_FAIL: Communication between Modem and IOS failed: link recovery resets modem
Dec 19 07:05:05.956: %PLATFORM-4-CELLULAR_MODEM_SKU_MISMATCH: Mismatch detected between installed modem Unknown modem on SKU type C881G-4G-GA-K9. Expected modem for this SKU is MC7304

Hello,

post the output of:

debug event manager action cli

while you run the script.

[balaji.bandi]

that should work  as expected

event manager run SKU_RELOAD  - what is the outcome.

[Felixsson1]

Router#event manager run SKU_RELOAD
EEM policy SKU_RELOAD not registered with event none Event Detector

[Georg Pauwen]

Hello,

start the script by adding:

Router#send log Unknown modem on SKU type C881G-4G-GA-K9

This will put the matched syslog pattern in the log and trigger the EEM. Post the output of 'debug event manager action cli' then...

[Felixsson1]

It's C881G-4G-GA-K9 and the IOS is Version 15.5(3)M4a.

Friend I do LAB, and I success do reload 
BUT BUT BUT this lab and I did not finish it 

event manager applet SKU_RELOAD
event syslog pattern " .  * Unknown modem on SKU type C881G-4G-GA-K9 . * " <<- this meaning dont care about timestamp and other words appear in syslog only within ".* ---.*" is important 
action 1.0 cli reload   <<- you can direct add reload under action 

WHAT I concern here ?
with normal reload the R ask to save config if you reload without save the config then it will be lost.
so I need time to finish lab first we must save the config then do reload. 

Thanks 

[Felixsson1]

Thanks for the quick update! I think the problem might be with the syslog pattern since I didn't put .* at the beginning and at the end to ignore rest of the text, meaning that my script will work if only if there is a exact syslog mesagge "Unknown modem on SKU type C881G-4G-GA-K9" which in my case it's not.

[MHM Cisco World]

friend again you need to save the config or it will LOST every time even action done. 
good luck.

[Felixsson1]

This is the final configuration that finally works:

event syslog pattern ".*Unknown modem on SKU type C881G-4G-GA-K9.*"
trigger delay 2000
action 1 cli command "ena"
action 2 cli command "reload" pattern "confirm"
action 3 cli command "y"

[MHM Cisco World]

action 1 cli command "ena"
action 2 cli command "reload" pattern "confirm"
action 3 cli command "y"

instead of above 
action 1 cli reload <<- that only if your EEM ver support it 

and I glad the issue is solved. 
good luck friend 

[Felixsson1]

Thanks for the help!
