Log via HSL total response time Only when there is a spesific value

I think something like this should work.

when RULE_INIT  {
    set static::bigip [info hostname]
    set static::facility <191>
    set static::hsl_prefix "$static::facility|host=$static::bigip"
}

when CLIENT_ACCEPTED {
    set hsl [HSL::open -proto UDP -pool pool-tng-graylog-HSL]
    set tcp_start_time [clock clicks -milliseconds]
}

when HTTP_REQUEST {
    set http_request_time [clock clicks -milliseconds]

    set log_request 0
    if { [HTTP::header exists "SOAPAction"] } {
        switch -glob [string tolower [HTTP::header "SOAPAction"]] {
            "*deposit* -
            "*withdrawal* {
                set log_request 1
            }
            default {
                set log_request 0
            }
        }
    }
}

when HTTP_REQUEST_SEND  {
    set http_request_send_time [clock clicks -milliseconds]
}

when LB_SELECTED  {
    set lb_selected_time [clock clicks -milliseconds]
    set hsl_prefix "${static::hsl_prefix}|Winweb=[LB::server addr]|F5_ClientIP=[client_addr]"
}

when SERVER_CONNECTED  {
    set connection_time [expr {[clock clicks -milliseconds] - $lb_selected_time}]
}

when HTTP_RESPONSE  {
    set upstream_time [expr {[clock clicks -milliseconds] - $http_request_send_time}]
}
when HTTP_RESPONSE_RELEASE {
    if { $log_request } {
        HSL::send $hsl "$hsl_prefix|event=X_REQUEST|total_time=[expr {[clock clicks -milliseconds] -    $http_request_time}]|upstream_time=$upstream_time|connection_time=$connection_time|vserver_name=[virtual name]\n"
    }
}
