How about this:

Code:

awk '
{
  for(i= 1; i< NF - 1; i+=3) {
    now=$i
    split($i, tm, ":")
    now=tm[1]*3600+tm[2]*60+tm[3]
    status=$(i+1)
    host=$(i+2)
    if(lastTime[host])
        totalTime[host] += now - lastTime[host]
    lastTime[host]=now
    if(status == "DN") Failure[host]++
    Reading[host]++
  }
}
END {
    for(host in lastTime)
       if (Failure[host])
           if (Failure[host] == Reading[host])
               print host " = 0"
           else
               print host " = " totalTime[host] / Failure[host]
       else
           print host " = No Failures"
}' infile

Infile:

Code:

08:51:36 DN 127.0.0.1 08:51:36 UN 127.0.0.2 08:51:36 UN 127.0.0.3 08:53:50 DN 127.0.0.1 08:53:50 DN 127.0.0.2 08:53:50 UN 127.0.0.3
08:58:36 DN 127.0.0.1 08:58:36 DN 127.0.0.2 08:58:36 UN 127.0.0.2

Result:

Code:

127.0.0.1 = 0
127.0.0.2 = 210
127.0.0.3 = No Failures
