JMX Tool

Java VisualVM is a tool that provides a visual interface for viewing detailed information about Java applications while they are running on a Java Virtual Machine (JVM), and for troubleshooting and profiling these applications.

Usage

Step1: Fetch IoTDB-sever.

Step2: Edit configuration.

• IoTDB is LOCAL
  View $IOTDB_HOME/conf/jmx.password, and use default user or add new users here.
  If new users are added, remember to edit $IOTDB_HOME/conf/jmx.access and add new users' access

• IoTDB is not LOCAL
  Edit $IOTDB_HOME/conf/iotdb-env.sh, and modify config below:

JMX_LOCAL="false"
JMX_IP="the_real_iotdb_server_ip"  # Write the actual IoTDB IP address

View $IOTDB_HOME/conf/jmx.password, and use default user or add new users here.
If new users are added, remember to edit $IOTDB_HOME/conf/jmx.access and add new users' access

Step 3: Start IoTDB-server.

Step 4: Use jvisualvm

1. Make sure jdk 8 is installed. For versions later than jdk 8, you need to download visualvm

2. Open jvisualvm

3. Right-click at the left navigation area -> Add JMX connection
   

4. Fill in information and log in as below. Remember to check "Do not require SSL connection".
   An example is:
   Connection：192.168.130.15:31999
   Username：iotdb
   Password：passw!d
