What operating system are you using?
What shell are you using?
How do you expect to deduce a failure rate from a single point in time? Are you instead maybe looking for a percentage of network node failures at this point in time?
What output are you hoping to produce from the sample input you have provided?
What have you tried on your own to get the output you want?

Three days ago we received an expected notice from our long time data center that they were going dark on Sept 12th.
About one and a half hours ago, after three days of marathon work, I just cut over the unix.com to a new data center with a completely new OS and Ubuntu distribution. (22 Replies)

5. What is on Your Mind?
Dear All,
There was a problem in the data center data, which caused the server to be unreachable for about an hour.
Server logs show the server did not crash or go down.
Hence, I assume there was a networking issue at the data center.
Still waiting for final word on what happened.

6. What is on Your Mind?
There was a problem with our data center today, creating a site outage (server unreachable).
That problem has been resolved.
Basically, it seems to have been a socially engineered denial-of-service attack against UNIX.com; which I stopped as soon as I found out what the problem was.

crm_uuid
CRM_UUID(8) [FIXME: manual] CRM_UUID(8)
NAME
crm_uuid - get a node's UUID
SYNOPSIS
crm_uuid [-w|-r]
DESCRIPTION
UUIDs are used to identify cluster nodes to ensure that they can always be uniquely identified. The crm_uuid command displays and modifies
the UUID of the node on which it is run.
When Heartbeat is first started on a node, it creates a UUID (in binary form) in /var/lib/heartbeat/hb_uuid. This file can be read and
written by means of crm_uuid.
Note
There are very rare circumstances when crm_uuid should be used to modify the UUID file. The most common is when it is necessary to set
a node's UUID to a known value when creating a new cluster.
OPTIONS
--write, -w
Write a UUID value to the /var/lib/heartbeat/hb_uuid file.
Warning
Use the -w option with care, because it creates a new UUID value for the node on which it is run. Various scripts across the
cluster might still use the old value, causing the cluster to fail because the node is no longer associated with the old UUID
value. Do not change the UUID unless you changed all references to it as well.
--read, -r
Read the UUID value and print it to stdout.
