# Examples: #
###########

# 1.) Check status of all Bro workers
# $ ./check_bro.sh -f /usr/local/bro-2.2/bin/broctl -T status

# 2.) Return average packet loss for the 3 named bro workers
# $ ./check_bro.sh -T loss -i "nids0,nids1,nids2"

# 3.) Check average packet loss of all bro workers against warning and critical thresholds i.e > 10% or 20% packet loss.
# $ ./check_bro.sh -T loss -i all -w 10 -c 20

# 4.) Check packet loss percentage for the last most recent interval from Bro's capture_loss.log above 10% loss.
# $ ./check_bro.sh -f /usr/local/bro-2.2/logs/current/capture_loss.log -T capture_loss -c 10

# 5.) Check average packet loss reported by Myricom's SnifferG driver for each Bro node.
# $ ./check_bro.sh -T myricom -i "192.168.1.254,192.168.1.253" -u bro
