List Virtual servers that are offline for past 90 days

Alternatively, the stats are collected since the device was last booted or manually cleared if my memory is correct.  With that, we can look at the uptime to assume how long the system has been collecting statistics that are returned.

#returns Days and hours that the system has been available for traffic since last reboot
tmsh show sys failover
#Returns 5 columns, Virtual Server Name, Availability, Status, Destination, Clientside Bits In, Clientside Bits Out sorted by the Clientside Bits In
tmsh -q -c 'cd /; show sys failover; show ltm virtual recursive' | awk '/Ltm::Virtual/ {printf $3" "} /Destination/ {printf $3 " "} /Availability/ {printf $3 " "} /State/ {printf $3" "} /Bits In/ {printf $3 " "} /Bits Out/ {printf $3 "\n"}' | column -t |sort -k4
