Preliminary verification on Cassandra failures

1) for i in dc1 dc2; do for j in cass solr; do for k in 1 2 3 4; do l=pramod$j-$i-a${k}s; printf "%-20s " $l; nodetool -h $l -u cassandra -pw CassandraJMXPass  status | wc -l; done; done; done

2) nmap -P0 -p 7199 127.0.0.1

3) netstat -an|grep -i listen

4) ps -p PID -o etime

5) echo $(($(date +%s%N)/1000000))
