EEM Scripting

[mgordon26]

Trying to write an EEM script to daily report if any dial-peers are in a busyout state.  Nothing seems to work for me.  2921 router running IOS c2900-universalk9-mz.SPA.155-3.M4a.bin

I have built a dial-peer for testing which is always in a busyout state.

This is what i have so far.

event manager session cli username "xxxxxx"
event manager applet CheckSIP-busyout
event timer cron cron-entry "30 7 * * *"
action 1.1 cli command "enable"
action 2.0 cli command "sh dial-peer voice | in busyout"
action 2.1 regexp "busyout.*=([a-z]+)," "$_cli_result" result result1
action 3.0 if $result1 eq "busyout"
action 3.2 mail server "172.31.xxxxx" to "cn-phones@xxxx" from "r01MC@xxxx" subject " Michigan City gateway is not responding " body "$_cli_result"
action 3.4 end

What does the output of "sh dial-peer voice | in busyout" look like?

[mgordon26]

r01micMAIvg#sh dial-p v su | i busyout
3333 voip up up 654789 0 syst ipv4:10.10.10.10 busyout
r01micMAIvg#

What you want is:

regexp "ipv4:[0-9.]+ busyout" "$_cli_result"

if $_regexp_result eq 1

 mail server "172.31.xxxxx" to "cn-phones@xxxx" from "r01MC@xxxx" subject " Michigan City gateway is not responding " body "$_cli_result"

end

i updated the script as suggested but it is still not working.

event manager applet CheckSIP-Trunk
event timer cron cron-entry "* 13 * * *"
action 1.1 cli command "enable"
action 2.0 cli command "sh dial-peer voice su | in busyout"
action 2.1 regexp "ipv4:[0-9.]+ busyout" "$_cli_result"
action 3.0 if $_regexp_result eq "1"
action 3.2 mail server "172.31.xxx" to "cn-phones@ixxx" from "r01MC@ixxx" subject " Michigan City gateway busyout dial-peer " body "$_cli_result"
action 3.4 end

Script is running but no message sent.

r01micMAIvg#sh even manage his ev

10 133 Actv success Wed Jul11 13:20:00 2018 timer cron applet: CheckSIP-Trunk

dial-peer is still in busyout state

r01micMAIvg#sh dial-p v su | i busyout
3333 voip up up 654789 0 syst ipv4:10.10.10.10 busyout
r01micMAIvg#

what now?

[Joe Clarke]

Enable "debug event manager action cli" and post the output after running the applet.

It could be your SMTP server is rejecting the email.  you might try adding :

syslog msg "Found busyout!!!"

Just to see if it's matching.  My local tests show there is no logic issue.

[mgordon26]

i added it and nothing shows in log

i add it following the send message line and still nothing shows

action 2.0 cli command "sh dial-peer voice su | in busyout"
action 2.1 regexp "ipv4:[0-9.]+ busyout" "$_cli_result"
action 3.0 if $_regexp_result eq "1"
action 3.1 syslog msg "Found busyout #1"
action 3.2 mail server "172.31.xxx" to "cn-phones@xx from "r01MC@xx" subject " Michigan City gateway busyout dial-peer " body "$_cli_result"
action 3.3 syslog msg "Found busyout #2"
action 3.4 end

[mgordon26]

i moved the action 3.15 end statement to follow the first syslog msg "Found busyout

now i am getting an email message and the second syslog msg "Found busyout message is writing to the log.

action 2.0 cli command "sh dial-peer voice su | in busyout"
action 2.1 regexp "ipv4:[0-9.]+ busyout" "$_cli_result"
action 3.0 if $_regexp_result eq "1"
action 3.1 syslog msg "Found busyout #1"
action 3.15 end
action 3.2 mail server "172.31.235.70" to "cn-phones@ivytech.edu" from "r01MC@ivytech.edu" subject " Michigan City gateway busyout dial-peer " body "$_cli_result"
action 3.3 syslog msg "Found busyout #2"
!

i deleted the busyout dial-peer so now there are no busyout dial-peers yet the message is still being sent so it appear the IF test is not working.

[mgordon26]

still sending the message but the body only has

r01micMAIvg#

where before i deleted the busyout dial-peer the body contained

3333   voip  up   up             654789             0  syst ipv4:10.10.10.10              busyout  

r01micMAIvg#

Ah!  This helps.  There are more spaces.  Try this:

regexp "ipv4:[0-9]+ +busyout" "$_cli_result"

And your end needs to go at the end to make sure all of the conditional statements are only executed when the regexp matches.

[mgordon26]

that fixed it!

thank you much.

i see i had a typo, missing the summary part of the command. i correct that and it still fails.
