Notification of alarms via email (EEM) of chassis temperature

[ErickArteaga234]

hi all

I have a question regarding the EEM feature, I have a catalyst 4500 switch with the version (cat4500e-universalk9.SPA.03.11.02.E.152-7.E2.bin ").

I have looked for documentation regarding the sending of temperature alarms and that these are sent via email, I have carried out a test through an interface and this is satisfactory.

when entering the command "show environment temperature "

throws me the following:

Module Sensor                                       Temperature Status

My question is, can temperature alarms be generated and these can be sent via mail, I can generate by means of EEM, the sending of the first temperature threshold of each module and sensor?

note: I share my script, based on one where cpu notifications were sent

event manager environment _email_to (xxxxxx)
event manager environment _email_server (xxxxxx)
event manager environment _dns_server (xxxxxxx)
event manager environment _email_from (xxxxxxx)
event manager environment _email_from_cc (xxxxxxx)

event manager applet environment
event syslog pattern "%ENVMON-:"
trigger
action 1.0 syslog priority notifications msg "envi error - mailC1 sent"
action 1.5 mail server "104.x.x.x" to "_email_to" from "_email_from" cc "_email_from_cc" subject "Environment" body "$_syslog_msg"
action 2.0 info type syslog history
action 2.5 syslog msg "$_syslog_msg"
action 3.0 cli command "show environment temperature"
action 4.0 set lines "0"
action 5.0 foreach line "$_cli_result" "\n"
action 6.0 if $lines gt "30"
action 7.0 break
action 8.0 append output "$line"
action 9.0 increment lines

regards!

For now you doing based on the syslog alert trigger sending email, this is working, just to clarity of requirement, you looking ""show environment temperature " command send email using EEM Script ? is this correct ?

action 1.0 cli command "show environment temperature | redirect flash:environ.txt"
action 2.0 cli command "more flash:environ.txt"
action 3.0 mail server "x.x.x.x" to "myname@bb.com" from "eemcisco@bb.com" subject "Environment report" body "$_cli_result"
action 4.0 cli command "del /force flash:environ.txt"

Hi ....Tanks for helping me !!

Not entirely, I was wrong to explain it, sorry. When entering the “show environment temperarure” command... and validating the temperature of the box, he observed that there is a temperature alarm threshold for each module and sensor... so I'm trying to automate an email (alert)... when a certain module or sensor .. exceeds that threshold.

Regards!!

Ok no issue, the way you configured CPU, you get an alert in event when the chassis temp go higher  ( you can also do with SNMP if you have any NMS in house)

based in the Logs you can generate email. (same way you do in EEM)  - for now all OK you wont be able to test (not you can simulate in production)

just for reference how the alerts generated when the chassis get higher temp.
