How to register EEM Tcl script

Hello,
I've a EEM tcl script in bootflash. How to register EEM script. I did the following but it couldn't locate the script in bootflash.
switch2(config)#event manager policy bootflash:eem-stuckcpu.tcl type user
EEM configuration: policy file bootflash:eem-stuckcpu.tcl could not be found
switch2(config)#
switch2(config)#event manager policy eem-stuckcpu.tcl type user
EEM configuration: policy file eem-stuckcpu.tcl could not be found
Thanks,

You need to configure:
event manager directory user policy bootflash:
Then use:
event manager policy eem-stuckcpu.tcl

Stopping EEM/TCL script

How can I stop a pending EEM/TCL script? I have a Catalyst 4506 version 12.2(40)SG. The command 'event manager scheduler clear' isn't available. The output of 'show event manager policy pending' shows:
No. Time of Event             Event Type          Name
1    Wed Mar 3 09:39:31 2010 none                script: test_err.tcl
2    Wed Mar 3 10:56:42 2010 timer watchdog      script: free_mem.tcl
3    Wed Mar 3 11:43:19 2010 syslog              applet: Login-Fail
So the policies coming after the stuck policy won't run. I've tried to un-register/re-register the policy, but it didn't help.

If your device does not support "event manager scheduler clear" the only way to terminate a stuck, or long-running EEM policy is to reboot.

EEM TCL script configuration issue

Hi Experts,
I need help with an EEM TCL script for the CRS platform that generates a SYSLOG message after the CPU reaches a threshold value and then stays over the threshold value for 15 minutes, I've already tryied several thing and the last TCL script that I tested generated the SYSLOG message when the CPU reaches the threshold but I can't seem to find any way to make it wait the 15 min over the threshold and then generate the message.
My current script looks like this:
::cisco::eem::event_register_wdsysmon timewin 900 sub1 cpu_tot op ge val 70
namespace import ::cisco::eem::*
namespace import ::cisco::lib::*
array set event_details [event_reqinfo]
action_syslog msg "sub1 is $event_details(sub1)"
action_syslog msg "High CPU threshold value over 70%"
puts ok
I've tryied using the 'period' option for the 'cpu_tot' variable but the TCL script was'nt recognized and couldn't be registered, and I'm using the 'timewin' option here but it seems to be wrong as it says it's the time it has for multiple sub-events to ocurr in order for the script to execute.
timewin
(Optional) Time window within which all of the subevents have to occur in order for an event to be generated and is specified in SSSSSSSSSS[.MMM] format. SSSSSSSSSS format must be an integer representing seconds between 0 and 4294967295 inclusive. MMM format must be an integer representing milliseconds between 0 and 999).
Also, the 'period' option I believe wouldn't have worked because I understand that it referrs to the time period that the script will take to monitor the CPU:
•1. cpu_tot [op gt|ge|eq|ne|lt|le] [val ?] [period ?]
op
(Optional) Comparison operator that is used to compare the collected total system CPU usage sample percentage with the specified percentage value. If true, an event is raised.
val
(Optional) Percentage value in which the average CPU usage during the sample period is compared.
period
(Optional) Time period for averaging the collection of samples and is specified in SSSSSSSSSS[.MMM] format. SSSSSSSSSS format must be an integer representing seconds between 0 and 4294967295, inclusive. MMM format must be an integer representing milliseconds between 0 and 999. If this argument is not specified, the most recent sample is used.
As I said, I couldn't try this because the script send an error when I tried to register using the following line:
::cisco::eem::event_register_wdsysmon sub1 cpu_tot op ge val 70 period 900
This is the error message that appeared:
RP/0/RP0/CPU0:CRS(config)#event manager policy test.tcl username cisco
RP/0/RP0/CPU0:CRS(config)#commit
Thu Aug 29 12:35:43.569 CDT

event manager policy test.tcl username cisco persist-time 3600
!!% Embedded Event Manager configuration: failed to retrieve intermediate registration result for policy test.tcl
end
Anyway, to make this work I understand that I need nested TCL scripts that do the following:
•1. Monitor the CPU and when it reaches the threshold install another TCL policy that counts down 15 min.
•2. If the second TCL policy reaches zero then it should generate the SYSLOG message.
•3. Monitor the CPU while this is running and if it falls below the threshold it should stop the second TCL policy.
I don't know how I can acomplish this so if anyone can help me with this or show me another way to do this I would really appreciate it.
Thanks in advance for all your help!

Neither option is likely to do what you want. The timewin is for correlating multiple events, and period is the polling interval. What you want is to create a timer when the CPU is first detected as being high, countdown 15 minutes, then alert you. You can do this with a nested EEM policy. For example, you can add the following to your existing policy:
proc get_pol_dir { fd } {
    set res {}
    set output [cli_exec $fd "show event manager directory user policy"]
    set output [string trim $output]
    regsub -all "\r\n" $output "\n" result
    set lines [split $result "\n"]
    foreach line $lines {
        if { $line == "" } {
            continue
        if { ! [regexp {\s} $line] && ! [regexp {#$} $line] } {
            set res $line
            break
    if { $res == {} } {
        return -code error "The user policy directory has not been configured"
    return $res
if { [catch {cli_open} result] } {
    error $result $errorInfo
array set cli $result
set output [cli_exec $cli(fd) "show event manager policy registered | inc tm_alert_high_cpu.tcl"]
if { [regexp {tm_alert_high_cpu.tcl} $output] } {
    exit 0
set poldir [get_pol_dir $cli(fd)]
set polname "${poldir}/tm_alert_high_cpu.tcl"
set fd [open $polname "w"]
puts $fd "::cisco::eem::event_register_timer countdown time 900"
puts $fd "namespace import ::cisco::eem::*"
puts $fd "namespace import ::cisco::lib::*"
puts $fd "action_syslog msg \"CPU has been over 70% for 15 minutes\""
close $fd
cli_exec $cli(fd) "config t"
cli_exec $cli(fd) "event manager policy tm_lert_high_cpu.tcl username eem"
cli_exec $cli(fd) "commit"
cli_exec $cli(fd) "end"
catch {cli_close $cli(fd) $cli(tty_id)}
Additionally, you'll want another permanently configured policy that checks for a low CPU threshold. Something like:
::cisco::eem::event_register_wdsysmon sub1 cpu_tot op le val 10
namespace import ::cisco::eem::*
namespace import ::cisco::lib::*
if { [catch {cli_open} result] } {
    error $result $errorInfo
array set cli $result
cli_exec $cli(fd) "config t"
cli_exec $cli(fd) "no event manager policy tm_alert_high_cpu.tcl"
cli_exec $cli(fd) "commit"
cli_exec $cli(fd) "end"
catch {cli_close $cli(fd) $cli(tty_id)}

IP SLA EEM/Tcl Scripts

Hello Community,
I have been testing a EEM/Tcl scripts for IP SLA. However, after testing I realised that the script didn't go far enough in identifying the link(s) that has actually gone down.
I was wondering if someone knows any good EEM/Tcl scripts for IP SLA?
Cheers
Carlton

What about it doesn't work? Is the policy not triggering? Is the IPSLA operation not transitioning state?

EEM-TCL Script to switch config from interface X to interface Y

Hello Guys,
I’m trying to create a script which is controlled by an EEM-UPDOWN event of an interface. What I’m trying to do is, if interface X is down for some reason it should copy the interface configuration to interface Y.
So my problem is I’m very new to eem-tcl scripting and I have some basic problem hopefully u can help me =) I’m working on a ASR9K !
So what i have done so fare:
::cisco::eem::event_register_syslog occurs 1 pattern ".*CHANGED.*$_sat_1_link_1.*" maxrun 90
namespace import ::cisco::eem::*
namespace import ::cisco::lib::*
array set arr_einfo [event_reqinfo]
if {$_cerrno != 0} {
    set result [format "component=%s; subsys err=%s; posix err=%s;\n%s" \
      $_cerr_sub_num $_cerr_sub_err $_cerr_posix_err $_cerr_str]
    error $result
if [catch {cli_open} result] {
    error $result $errorInfo
} else {
    array set cli1 $result
action_syslog priority emergencies msg "start script testv1_1"
#puts "\nEXECUTE CLI COMAND :\n"
set out {cli_exec $cli1(fd) "show running-config formal interface $_sat_1_link_1"}
set xout [split $out \n]
#puts "DEBUG : $xout \n\n"
set anz [llength $xout]
#puts "DEBUG : count rows = $anz \n\n"
for {set ii "0"} {$ii < $anz } {incr ii} {
    set indexout [lindex $out $ii]
    regexp {([\w]+)[ ]([\w\d/]+)\s(.*)} $indexout a b c d
   #puts "\nDEBUG START"
    #puts "\nindex Nr $ii"
    #puts "Full Match: $a"
    #puts "Sub Match1: $b"
    #puts "Sub Match2: $c"
    #puts "Sub Match3: $d"
    #puts "DEBUG END\n"
   set intsrc {cli_exec $cli1(fd) "no $b $_sat_1_link_1 $d"}
   set intdest {cli_exec $cli1(fd) "$b $_sat_1_link_2 $d"}
if [catch {cli_exec $cli1(fd) "commit"} result] {
    error $result $errorInfo
if [catch {cli_exec $cli1(fd) "end"} result] {
    error $result $errorInfo
action_syslog priority emergencies msg "End script testv1_1"
ps. $_sat_1_link_1 and $_sat_1_link_2 are globaly set per cli in the event manager env.
Thanks for your help and hopefully u can help me with this script

Hey
after show running-config formal interface TenGigE 0/0/2/1 the cli output example is :
interface TenGigE0/0/2/1 description Test: 0-43
interface TenGigE0/0/2/1
interface TenGigE0/0/2/1 shutdown
and now i want to split the config with my regex
regexp {([\w]+)[ ]([\w\d/]+)\s(.*)} $indexout a b c d
As example line 1
set x= "TenGigE0/0/2/2"                  --> =dest_interface
a= interface TenGigE0/0/2/1 description Test: 0-43
b= interface
c= TenGigE0/0/2/1
d= description Test: 0-43
do this
cli_exec $cli1(fd) "no $b $c $d"      --->no interface TenGig E0/0/2/1 description Test: 0-43
cli_exec $cli1(fd) " $b $x $d"          ---> interface TenGigE0/0/2/2 description Test: 0-43
and from this point it shoud do this until there are no config lines =)
as a final result is should copy the whole config from interface X to interface Y if the trigger is active
but as i see, the main problem is to get the CLI output in a format like this
set xy = interface TenGigE0/0/2/1 description Test: 0-43\ninterface TenGigE0/0/2/1\ninterface TenGigE0/0/2/1 shutdown
or in an index like this:
Index | command
1         interface TenGigE0/0/2/1 description Test: 0-43
2         interface TenGigE0/0/2/1
3         interface TenGigE0/0/2/1 shutdown
Thx

EEM / Tcl Script Help Please

Hello Community,
I have been evaluating a Tcl Script posted here sometime ago, designed to help monitor track interfaces and routes, see attached.
I believe I have applied the configurations correctly, however when I test the script by shutting down interfaces nothing happens.
I'm sure its something very simple that I'm missing.
I wonder if someone could take a look at the configs and let me know what I'm doing wrong. I have also attached a diagram.

Joseph,
I did read again and I got it to work :-)

On a slightly different topic, is it possible to 'track' a static ip address?
For example, I have the following tracking configured:
track 1 ip route 0.0.0.0 0.0.0.0 reachability
track 2 interface FastEthernet0/0 ip routing
track 3 interface FastEthernet0/1 ip routing
track 4 ip route 180.80.8.4 255.255.255.255 reachability
track 5 ip route 170.70.7.4 255.255.255.255 reachability
R3#show track brie
Track   Object                         Parameter        Value
1       ip route 0.0.0.0/0            reachability     Up (static)
2       interface FastEthernet0/0      ip routing       Up
3       interface FastEthernet0/1      ip routing       Up
4       ip route 180.80.8.4/32        reachability     Down (no route)
5       ip route 170.70.7.4/32        reachability     Down (no route)
However, you will see that track 4 and 5 are down. This is because, although I can ping 180.80.8.4 and 170.70.7.4 the actual ip addresses don't appear in the routing table:
Gateway of last resort is 0.0.0.0 to network 0.0.0.0
     170.70.0.0/24 is subnetted, 1 subnets
C       170.70.7.0 is directly connected, FastEthernet0/0
     10.0.0.0/24 is subnetted, 1 subnets
C       10.1.1.0 is directly connected, FastEthernet1/0
     180.80.0.0/24 is subnetted, 1 subnets
C       180.80.8.0 is directly connected, FastEthernet0/1
     150.50.0.0/24 is subnetted, 1 subnets
C       150.50.5.0 is directly connected, Ethernet2/0
S*   0.0.0.0/0 is directly connected, FastEthernet1/0
R3#
Therefore, is there way of creating a track for /32 ip addresses?
I hope that makes sense.
Cheers

SNMP GET operation via EEM Tcl Scripting

Hi Experts,
I am writing to you because I was browsing through the archives and saw in one discussion the following command:
sys_reqinfo_snmp_set oid 1.3.6.1.2.1.2.2.1.7.2.3 int 2 community private ipaddr 1.1.1.1
I am trying to the get the "get" version of the above command. This means a command that gives you the ability to poll an external/remote SNMP Agent MIB. This is the reason I highlited the "ipaddr" keyword.
The following command gives you the option to locally poll an object, but it does not give you the option (as indicated in the available literature) to do it on an external device:
sys_reqinfo_snmp oid ? get_type exact|next
In applet configuration mode there is a way to achieve that but I have not found any indication on how to do it via Tcl, which supposedly supersedes what you can do via applet configuration.
Thanks in advance for you knowledge and help.

Assuming you have a new enough version of EEM, the command is:
sys_reqinfo_snmp oid OID get_type {exact|next} community COMMUNITY ipaddr IPADDR

Registering a Tcl Script

I have an easy problem that I'm obviously over looking. I imagine it's been asked before.
I've downloaded the multiple pipe support script, copied it to flash, used the event manager policy cl_multi_pipe.tcl command.
Then I get an error:

Signing byte-encoded TCL script for EEM

Good day,
I am trying to figure out how to sign a TCL script which is distributed in byte-encoded form.
The byte coding is performed with TCL pro (http://sourceforge.net/projects/tclpro/files/TclPro-1.4.1/)
Any pointers on how to do it will be much appreciated.
Regards,
Alexei

EEM 3.4 should support third party signing of Tcl policies. As to whether or not byte-code compiled policies will be supported is uncertain. However, you should be able to sign a byte-code compiled Tcl script (regular Tcl script, and not EEM policy) by putting the signature after the closing tbcload '}'. I assume the same thing will eventually be doable with EEM.

Using EEM and TCL scripts for voice

HI all,
I'd like to use eem to check Sip dial-peer status+interface BRI status, when sip dial-peer has no answer to invite and bri interface is down the LAN interface must be shutted down. Is it possible to avhieve it using eem? I didn't find anything for eem monitoring sip dial-peers...
thanks
Massimiliano

EEM doesn't have any ability to control the data plane currently. Therefore, there is no direct voice tie-in. There is a way to do Tcl scripting of some voice operations (e.g. IVR scripts), but those do not relate to EEM.
That said, if there are some show commands which provide you the data you need, you can create an EEM timer policy (i.e. one that runs periodically), parsers the show command output, and takes further action if the output contains certain patterns. Depending on the version of IOS, this may require an EEM Tcl script, or you may be able to do it within an EEM applet.
If you need further assistance, you will need to provide your IOS version, and the exact commands (and output) which would tell you if the SIP peer isn't getting an answer and the BRI interface is truly down (I'm imagining something like "show isdn status" for this one).
