Monitoring dual core (Supervisor Engine 7-E) through EEM Script.

Hi,

I have a Cisco Catalyst 4500E Supervisor Engine 7-E and configured an EEM Script to monitor the dual core CPU Utilization through PRTG Network Monitor.

event manager applet dualcore authorization bypass

event timer cron cron-entry "* * * * 0-6"

!

action 100 cli command "en"

action 120 cli command "show process cpu | include five"

!

action 220 regexp "Core 0: CPU utilization for five seconds: ([^%]+)%; one minute: ([^%]+)%; five minutes: ([^%]+)%.*" $_cli_result result c0cpu5sec c0cpu1min c0cpu5min

action 240 if $_regexp_result eq 1

action 260 end

!

action 320 regexp "Core 1: CPU utilization for five seconds: ([^%]+)%; one minute: ([^%]+)%; five minutes: ([^%]+)%.*" $_cli_result result c1cpu5sec c1cpu1min c1cpu5min

action 340 if $_regexp_result eq 1

action 360 end

!

action 440 cli command "config t"

action 441 cli command "snmp mib expression owner cisco name c0cpu5sec"

action 442 cli command "expression $c0cpu5sec"

action 443 cli command "snmp mib expression owner cisco name c0cpu1min"

action 444 cli command "expression $c0cpu1min"

action 445 cli command "snmp mib expression owner cisco name c0cpu5min"

action 446 cli command "expression $c0cpu5min"

!

action 550 cli command "config t"

action 551 cli command "snmp mib expression owner cisco name c1cpu5sec"

action 552 cli command "expression $c1cpu5sec"

action 553 cli command "snmp mib expression owner cisco name c1cpu1min"

action 554 cli command "expression $c1cpu1min"

action 555 cli command "snmp mib expression owner cisco name c1cpu5min"

action 556 cli command "expression $c1cpu5min"

!

action 600 cli command "end"

!

end

It works fine but on the logging buffer there are a lot of %SYS-5-CONFIG_I: Configured from console by  on vty0 (EEM:moncores) messages   -one per minute-   here an example:

Oct 29 17:54:01: %SYS-5-CONFIG_I: Configured from console by  on vty0 (EEM:dualcore)

Oct 29 17:55:01: %SYS-5-CONFIG_I: Configured from console by  on vty0 (EEM:dualcore)

Oct 29 17:56:01: %SYS-5-CONFIG_I: Configured from console by  on vty0 (EEM:dualcore)

Oct 29 17:57:01: %SYS-5-CONFIG_I: Configured from console by  on vty0 (EEM:dualcore)

I considered to use the logging suppress duplicates command to prevent the consecutive logging of more than one copy of the same system logging (syslog) message but it is only available to the Cisco IOS XR.

Someone could help me to determine if it is possible to avoid this messages through Embedded Syslog Manager, I tried to do that but

I was not successful.

Regards,

~Sergio

Could you help me to avoid this or it is not possible to do it...?!

You found a bug in the converter.  Edit your script and remove the "set-type" token.  That should not have been in the converted Tcl code.

This is working for me.  Are you sure "tester" is a valid SNMP read-write community string?
