EEM Script to supervise FXO analog lines.

Software Version: 15.0(1r)M6


Problem Details: I need some help developing a EEM script to supervise an FXO line. The command I'm using to see whether or not an FXO phone lines are operational is


test voice port 0/0/0 si-reg-read 29 1

test voice port 0/0/1 si-reg-read 29 1


I would like to run these command everyday and if the output is ever


Register 29 = 0x00


I would like it to email me.

------------------------------------

We need to know if the analog lines in the back of the router are active and have dialtone each day. We had an incident in the past where the site tried to use 911, and it failed because the PSTN line was disconnected at the service provider but we didn't know. I would like to use the


test voice port 0/0/0 si-reg-read 29 1


command to verify line voltage/dialtone on the line. Furthermore I would like to script this so that if the output of that test command = 0x00 ( no voltage) will send an email to us letting us know something has happened to that analog line. Here is an example of how far I was able to get with it. (this code doesn't work right , but you should get the gist.)


event manager environment _mail_smtp *****.****.org

event manager environment _mail_domain ******.org

event manager environment _mail_rcpt1 *****@******.org

event manager environment _mail_rcpt2 ******@*****.org

event manager applet test

event timer watchdog time 86400
action 1.0 cli command "enable"
action 2.0 cli command "test voice port 0/0/0 si-reg-read 29 1"
action 3.0 cli command "test voice port 0/0/1 si-reg-read 29 1"
action 4.0 regexp " 0x00 " $_cli_result result
action 5.0 if $_regexp_result eq 1

action 6.0 info type routername
action 7 .0 mail server "$_mail_smtp" to "$_mail_rcpt1" from "$_info_routername@$_mail_domain" subject "Analog line down on $_info_routername" body "$_cli_result"
action 8.0 mail server "$_mail_smtp" to "$_mail_rcpt2" from "$_info_routername@$_mail_domain" subject "Analog line down on $_info_routername" body "$_cli_result"
action 9.0 else
action 11.0 end

Any help you guys can give is greatly aprpeciated. TAC said they can't help me. But they said your the ones to ask.

Thanks.

EEM Script to supervise FXO analog lines.

This applet looks okay for the most part.  What you'll need to do, though, is store the value of $_cli_result after each test command and check each output.  For example:

action 2.1 set port_0_0_0 $_cli_result

action 3.1 set port_0_0_1 $_cli_result

action 3.2 set bad_line 0

action 4.0 regexp "0x00" $port_0_0_0

action 4.1 if $_regexp_result eq 1

action 4.2  append mail_result $port_0_0_0

action 4.3  set bad_line 1

action 4.4 end

action 4.5 regexp "0x00" $port_0_0_1

action 4.6 if $_regexp_result eq 1

action 4.7  append mail_result $port_0_0_1

action 4.8  set bad_line 1

action 4.9 end

action 5.0 if $bad_line eq 1

...

Then use $mail_result instead of $_cli_result in your email body.  And delete action 9.0.

EEM Script to supervise FXO analog lines.

Thanks for the advice. I took what you gave me there and added in the important bits. I also specified a port which would have a result of 0x00 for testing purposes however I see no output on the screen and I do not receive an email. This is what I have.I'm using event trigger none, and running it by "event manager run test" .. I think that should work?

event manager applet test

event none

action 1.0 cli command "enable"

action 2.0 cli command "test voice port 0/0/0 si-reg-read 29 1"

action 2.1 set port_0_0_0 "$_cli_result"

action 3.0 cli command "test voice port 0/0/2 si-reg-read 29 1"

action 3.1 set port_0_0_1 "$_cli_result"

action 3.2 set bad_line "0"

action 4.0 regexp "0x00" "$port_0_0_0"

action 4.1 if $_regexp_result eq 1

action 4.2  append mail_result "$port_0_0_0"

action 4.3  set bad_line "1"

action 4.4 end

action 4.5 regexp "0x00" "$port_0_0_1"

action 4.6 if $_regexp_result eq 1

action 4.7  append mail_result "$port_0_0_1"

action 4.8  set bad_line "1"

action 4.9 end

action 5.0 if $bad_line eq 1

action 7.0  mail server "$_mail_smtp" to "$_mail_rcpt2" from "$_info_routername@$_mail_domain" subject "Analog line down on $_info_routername" body "$mail_result"

!

end

Thanks again for your response!

You need to add:

action 8.0 end

You should also enable "debug event manager action cli" and "debug event manager action mail" to confirm that the CLI output is looking and what is going on during execution.

Thanks for catching that! I turned on the debugs and re-ran it. Im a little concerned that the "test voice" command is not reutrning results before the script ends and therefore nothing is being checked... There is about a second delay before the results from the test are displyaed in the CLI... any thoughs on that? Here is the output from the CLI.

If the commands aren't synchronous, then this applet approach will not work.  It looks like the results are sent via syslog.  If you register this applet, what do you see printed:

event manager applet test-test

event syslog pattern "Values read"

action 1.0 syslog msg "XXX: Result is '$_syslog_msg'"

This is the result when I try to run that applet.

GATEWAY-ROUTER#event manager run test-test

EEM policy test-test not registered with event none Event Detector

No, this policy is not run that can be run manually.  You'll need to run the test commands again so that they generate their result messages.  Then look at the results from this applet.

Ok so when I execute the test command this is what I see in the console.

Looks as if It sees part of it but not the value of the register..

Cisco Employee

Yeah, I don't have a good answer for you.  Is there any way to go back and use a show command to look at the results of the last test?

New Member

Best I can come up with is this, but it does not show the value were looking for.

I do appreciate the amount of time you've put in to help me try and figure it out. I wish there was a way to do this.

EEM Script to supervise FXO analog lines.

I was hoping for a voice-specific command that would show the value of the last test.  The command would need to map the port to the value in some way.  You might try seeing what you get with:

event manager applet test-test

event tag 1 syslog patterm "Values read"

event tag 2 syslog pattern "Register 29"

trigger occurs 1 period 1

  correlate event 1 and event 2

action 1.0 syslog msg "XXX: Value is '$_syslog_msg'"

The problem is, even if this works, there's no way to truly tie the two messages together.  You could wait for two seconds between test commands and that would almost ensure the correctness, but it wouldn't necessarily be 100% valid.

Could we cat the results of the output to a file then grep the file? and delete it afterwards?

Cisco Employee

No.  The command produces no output directly.  Instead, it runs the test, then prints the results via logging messages.
