eem scripting for IP SLA

[Siddharth Tyagi]

I am trying to extract the numerical value from the followng using Embedded event manager(TCL Scripting)

i also have SLA probes running between 2 connected routers

sho ip sla statistics | sec SD Jitter

So i write the the following

conf ter

event manager applet STAT

event none  sync yes

action 1 cli command "enable"

action 2  cli command "sho ip sla stat | sec SD Jitter"

action 3 regexp  " [0-9]+ " $_cli_result result

action 4 puts "$result"

However it produces result

*Mar 27 16:42:08.806: %HA_EM-3-FMPD_UNKNOWN_ENV: fh_parse_var: could not find environment variable: result

*Mar 27 16:42:08.806: %HA_EM-3-FMPD_ERROR: Error executing applet STAT statement 4

pls clarify

hello - I have just moved your post to the Topic forums - you had posted your question in an obscure, non-visible, promotional community.  Hopefully our community users will see your question now

Does the "show ip sla stat | sec SD Jitter" show any output with numbers?   If not, then the result variable will not be populated.   Try adding line 2 below into your applet so if there is not a match it will not produce an error.

event manager applet STAT

event none  sync yes

action 1 cli command "enable"

action 2 set result "No match"

action 3  cli command "sho ip sla stat | sec SD Jitter"

action 4 regexp  " [0-9]+ " $_cli_result result

action 5 puts "$result"
