iRule Error

Hi All

I am busy implementing Cisco Tetration and required to deploy configuration on the F5.

I am following the GitHub article, https://github.com/f5devcentral/f5-tetration. I do however get a few errors when I run the scripts, thus not able to complete.

I then tried to deploy the settings manually and here I get an error when configuring the iRule. Can someone assist with what the following error refers to when deploying the iRule,

    01070151:3: Rule [/Common/irule_ipfix_tcp] error: /Common/irule_ipfix_tcp:11: error: [undefined procedure: IPFIX::destination][IPFIX::destination open -publisher /Common/ipfix-pub-1]
/Common/irule_ipfix_tcp:15: error: [undefined procedure: IPFIX::template][IPFIX::template create "flowStartMilliseconds \
sourceIPv4Address \
sourceIPv6Address \
destinationIPv4Address \
destinationIPv6Address \
sourceTransportPort \
destinationTransportPort \
protocolIdentifier \
octetTotalCount \
packetTotalCount

This is a portion of the iRule where the error appears to be when RULE_INIT { set static::http_rule1_dest "" set static::http_rule1_tmplt "" }

 CLIENT_ACCEPTED event to initiate IPFIX destination and template
when CLIENT_ACCEPTED {
  set start [clock clicks -milliseconds]
  if { $static::http_rule1_dest == ""} {
     open the logging destination if it has not been opened yet
    set static::http_rule1_dest [IPFIX::destination open -publisher /Common/ipfix-pub-1]
  }
  if { $static::http_rule1_tmplt == ""} {
     if the template has not been created yet, create the template
    set static::http_rule1_tmplt [IPFIX::template create "flowStartMilliseconds \

  }
}

Can someone assist with guiding as to where the issue might be.

Thanx
