Overhead Evaluation

Install JVMTop

wget https://github.com/patric-r/jvmtop/releases/download/0.8.0/jvmtop-0.8.0.tar.gz
tar -xzvf jvmtop-0.8.0.tar.gz
cd jvmtop-0.8.0

Run target system

Run the target system, write down the pid number

You can get the pid value of zookeeper by running cat $zookeeper_data/zookeeper_server.pid, cassandra by running pgrep -u "$USER" -f cassandra. You need to get the pid value of hdfs and hbase manually using ps command.

Record the cpu and memory usage

  1. Modify the pid and out_file variable run.sh
  2. Run the workload. You can use the throughput workload.
  3. Run immediately after the workload starts.
./run.sh
  1. Kill run.sh by using CTRL+C immediately after the workload has finished
  2. Modify path_raw in raw.py using the same file as out_file in run.sh. Also modify the path variable in raw.py for the output. This python script will filter the output of the run.sh
python3 raw.py
  1. Modify path in logparser.py using the same value as path in raw.py. This script will calculate the average of the cpu and memory usage
python3 logparser.py
