+# DataNode Configuration Parameters
+
+We use the same configuration files for IoTDB DataNode and Standalone version, all under the `conf`.
+
+* `datanode-env.sh/bat`：Environment configurations, in which we could set the memory allocation of DataNode and Standalone.
+
+* `iotdb-system.properties`：IoTDB system configurations.
+
+## Hot Modification Configuration
+
+For the convenience of users, IoTDB provides users with hot modification function, that is, modifying some configuration parameters in `iotdb-system.properties` during the system operation and applying them to the system immediately. 
+In the parameters described below, these parameters whose way of `Effective` is `hot-load` support hot modification.
+
+Trigger way: The client sends the command(sql) `load configuration` or `set configuration` to the IoTDB server.
+
+## Environment Configuration File（datanode-env.sh/bat）
+
+The environment configuration file is mainly used to configure the Java environment related parameters when DataNode is running, such as JVM related configuration. This part of the configuration is passed to the JVM when the DataNode starts.
+
+The details of each parameter are as follows:
+
+* MEMORY\_SIZE
+
+|Name|MEMORY\_SIZE|
+|:---:|:---|
+|Description|The minimum heap memory size that IoTDB DataNode will use when startup |
+|Type|String|
+|Default| The default is a half of the memory.|
+|Effective|After restarting system|
+
+* ON\_HEAP\_MEMORY

+|Description|JMX listening address. Only take effect if JMX\_LOCAL=false. 0.0.0.0 is never allowed|
+|Type|String|
+|Default|127.0.0.1|
+|Effective|After restarting system|
+
+## JMX Authorization
+
+We **STRONGLY RECOMMENDED** you CHANGE the PASSWORD for the JMX remote connection.
+
+The user and passwords are in ${IOTDB\_CONF}/conf/jmx.password.
+
+The permission definitions are in ${IOTDB\_CONF}/conf/jmx.access.

+| Description | IoTDB's strategy for selecting directories for TsFile in tsfile_dir. You can use a simple class name or a full name of the class. The system provides the following three strategies: <br>1. SequenceStrategy: IoTDB selects the directory from tsfile\_dir in order, traverses all the directories in tsfile\_dir in turn, and keeps counting;<br>2. MaxDiskUsableSpaceFirstStrategy: IoTDB first selects the directory with the largest free disk space in tsfile\_dir;<br>You can complete a user-defined policy in the following ways:<br>1. Inherit the org.apache.iotdb.db.storageengine.rescon.disk.strategy.DirectoryStrategy class and implement its own Strategy method;<br>2. Fill in the configuration class with the full class name of the implemented class (package name plus class name, UserDfineStrategyPackage);<br>3. Add the jar file to the project. |

+### Metric Configuration
+
+## Enable GC log
+
+GC log is off by default.
+For performance tuning, you may want to collect the GC info. 
+
+To enable GC log, just add a parameter "printgc" when you start the DataNode.
+
+```bash
+nohup sbin/start-datanode.sh printgc >/dev/null 2>&1 &
+```
+Or
+```cmd
+sbin\start-datanode.bat printgc
+```
+
+GC log is stored at `IOTDB_HOME/logs/gc.log`.
+There will be at most 10 gc.log.* files and each one can reach to 10MB.

+# DataNode Configuration Parameters
+
+We use the same configuration files for IoTDB DataNode and Standalone version, all under the `conf`.
+
+* `datanode-env.sh/bat`：Environment configurations, in which we could set the memory allocation of DataNode and Standalone.
+
+* `iotdb-datanode.properties`：IoTDB DataNode system configurations.
+
+## Hot Modification Configuration
+
+For the convenience of users, IoTDB provides users with hot modification function, that is, modifying some configuration parameters in `iotdb-datanode.properties` and `iotdb-common.properties` during the system operation and applying them to the system immediately. 
+In the parameters described below, these parameters whose way of `Effective` is `hot-load` support hot modification.
+
+Trigger way: The client sends the command(sql) `load configuration` to the IoTDB server.
+
+## Environment Configuration File（datanode-env.sh/bat）
+
+The environment configuration file is mainly used to configure the Java environment related parameters when DataNode is running, such as JVM related configuration. This part of the configuration is passed to the JVM when the DataNode starts.
+
+The details of each parameter are as follows:
+
+* MAX\_HEAP\_SIZE
+
+|Name|MAX\_HEAP\_SIZE|
+|:---:|:---|
+|Description|The maximum heap memory size that IoTDB can use |

+| Description | IoTDB's strategy for selecting directories for TsFile in tsfile_dir. You can use a simple class name or a full name of the class. The system provides the following three strategies: <br>1. SequenceStrategy: IoTDB selects the directory from tsfile\_dir in order, traverses all the directories in tsfile\_dir in turn, and keeps counting;<br>2. MaxDiskUsableSpaceFirstStrategy: IoTDB first selects the directory with the largest free disk space in tsfile\_dir;<br>You can complete a user-defined policy in the following ways:<br>1. Inherit the org.apache.iotdb.db.storageengine.rescon.disk.strategy.DirectoryStrategy class and implement its own Strategy method;<br>2. Fill in the configuration class with the full class name of the implemented class (package name plus class name, UserDfineStrategyPackage);<br>3. Add the jar file to the project. |

+### Metric Configuration
+
+## Enable GC log
+
+GC log is off by default.
+For performance tuning, you may want to collect the GC info. 
+
+To enable GC log, just add a parameter "printgc" when you start the DataNode.
+
+```bash
+nohup sbin/start-datanode.sh printgc >/dev/null 2>&1 &
+```
+Or
+```cmd
+sbin\start-datanode.bat printgc
+```
+
+GC log is stored at `IOTDB_HOME/logs/gc.log`.
+There will be at most 10 gc.log.* files and each one can reach to 10MB.

+# DataNode Configuration Parameters
+
+We use the same configuration files for IoTDB DataNode and Standalone version, all under the `conf`.
+
+* `datanode-env.sh/bat`：Environment configurations, in which we could set the memory allocation of DataNode and Standalone.
+
+* `iotdb-datanode.properties`：IoTDB system configurations.
+
+## Hot Modification Configuration
+
+For the convenience of users, IoTDB provides users with hot modification function, that is, modifying some configuration parameters in `iotdb-datanode.properties` during the system operation and applying them to the system immediately. 
+In the parameters described below, these parameters whose way of `Effective` is `hot-load` support hot modification.
+
+Trigger way: The client sends the command(sql) `load configuration` or `set configuration` to the IoTDB server.
+
+## Environment Configuration File（datanode-env.sh/bat）
+
+The environment configuration file is mainly used to configure the Java environment related parameters when DataNode is running, such as JVM related configuration. This part of the configuration is passed to the JVM when the DataNode starts.
+
+The details of each parameter are as follows:
+
+* MEMORY\_SIZE
+
+|Name|MEMORY\_SIZE|
+|:---:|:---|
+|Description|The minimum heap memory size that IoTDB DataNode will use when startup |
+|Type|String|
+|Default| The default is a half of the memory.|
+|Effective|After restarting system|
+
+* ON\_HEAP\_MEMORY
+
+|Name|ON\_HEAP\_MEMORY|
+|:---:|:---|
+|Description|The heap memory size that IoTDB DataNode can use, Former Name: MAX\_HEAP\_SIZE |
+|Type|String|

+|Description|JMX monitoring mode, configured as yes to allow only local monitoring, no to allow remote monitoring|
+|Type|Enum String: "true", "false"|
+|Default|true|
+|Effective|After restarting system|
+
+* JMX\_PORT
+
+|Name|JMX\_PORT|
+|:---:|:---|
+|Description|JMX listening port. Please confirm that the port is not a system reserved port and is not occupied|
+|Type|Short Int: [0,65535]|
+|Default|31999|
+|Effective|After restarting system|
+
+* JMX\_IP
+
+|Name|JMX\_IP|
+|:---:|:---|
+|Description|JMX listening address. Only take effect if JMX\_LOCAL=false. 0.0.0.0 is never allowed|
+|Type|String|
+|Default|127.0.0.1|
+|Effective|After restarting system|
+
+## JMX Authorization
+
+We **STRONGLY RECOMMENDED** you CHANGE the PASSWORD for the JMX remote connection.
+
+The user and passwords are in ${IOTDB\_CONF}/conf/jmx.password.
+
+The permission definitions are in ${IOTDB\_CONF}/conf/jmx.access.

+| Description | IoTDB's strategy for selecting directories for TsFile in tsfile_dir. You can use a simple class name or a full name of the class. The system provides the following three strategies: <br>1. SequenceStrategy: IoTDB selects the directory from tsfile\_dir in order, traverses all the directories in tsfile\_dir in turn, and keeps counting;<br>2. MaxDiskUsableSpaceFirstStrategy: IoTDB first selects the directory with the largest free disk space in tsfile\_dir;<br>You can complete a user-defined policy in the following ways:<br>1. Inherit the org.apache.iotdb.db.storageengine.rescon.disk.strategy.DirectoryStrategy class and implement its own Strategy method;<br>2. Fill in the configuration class with the full class name of the implemented class (package name plus class name, UserDfineStrategyPackage);<br>3. Add the jar file to the project. |

+### Metric Configuration
+
+## Enable GC log
+
+GC log is off by default.
+For performance tuning, you may want to collect the GC info. 
+
+To enable GC log, just add a parameter "printgc" when you start the DataNode.
+
+```bash
+nohup sbin/start-datanode.sh printgc >/dev/null 2>&1 &
+```
+Or
+```cmd
+sbin\start-datanode.bat printgc
+```
+
+GC log is stored at `IOTDB_HOME/logs/gc.log`.
+There will be at most 10 gc.log.* files and each one can reach to 10MB.

+# DataNode Configuration Parameters
+
+We use the same configuration files for IoTDB DataNode and Standalone version, all under the `conf`.
+
+* `datanode-env.sh/bat`：Environment configurations, in which we could set the memory allocation of DataNode and Standalone.
+
+* `iotdb-system.properties`：IoTDB system configurations.
+
+## Hot Modification Configuration
+
+For the convenience of users, IoTDB provides users with hot modification function, that is, modifying some configuration parameters in `iotdb-system.properties` during the system operation and applying them to the system immediately. 
+In the parameters described below, these parameters whose way of `Effective` is `hot-load` support hot modification.
+
+Trigger way: The client sends the command(sql) `load configuration` or `set configuration` to the IoTDB server.
+
+## Environment Configuration File（datanode-env.sh/bat）
+
+The environment configuration file is mainly used to configure the Java environment related parameters when DataNode is running, such as JVM related configuration. This part of the configuration is passed to the JVM when the DataNode starts.
+
+The details of each parameter are as follows:
+
+* MEMORY\_SIZE
+
+|Name|MEMORY\_SIZE|
+|:---:|:---|
+|Description|The minimum heap memory size that IoTDB DataNode will use when startup |

+|Effective|After restarting system|
+
+## JMX Authorization
+
+We **STRONGLY RECOMMENDED** you CHANGE the PASSWORD for the JMX remote connection.
+
+The user and passwords are in ${IOTDB\_CONF}/conf/jmx.password.

+| Description | IoTDB's strategy for selecting directories for TsFile in tsfile_dir. You can use a simple class name or a full name of the class. The system provides the following three strategies: <br>1. SequenceStrategy: IoTDB selects the directory from tsfile\_dir in order, traverses all the directories in tsfile\_dir in turn, and keeps counting;<br>2. MaxDiskUsableSpaceFirstStrategy: IoTDB first selects the directory with the largest free disk space in tsfile\_dir;<br>You can complete a user-defined policy in the following ways:<br>1. Inherit the org.apache.iotdb.db.storageengine.rescon.disk.strategy.DirectoryStrategy class and implement its own Strategy method;<br>2. Fill in the configuration class with the full class name of the implemented class (package name plus class name, UserDfineStrategyPackage);<br>3. Add the jar file to the project. |

+### Metric Configuration
+
+## Enable GC log
+
+GC log is off by default.
+For performance tuning, you may want to collect the GC info. 
+
+To enable GC log, just add a parameter "printgc" when you start the DataNode.
+
+```bash
+nohup sbin/start-datanode.sh printgc >/dev/null 2>&1 &
+```
+Or
+```cmd
+sbin\start-datanode.bat printgc
+```
+
+GC log is stored at `IOTDB_HOME/logs/gc.log`.
+There will be at most 10 gc.log.* files and each one can reach to 10MB.

+# DataNode Configuration Parameters
+
+We use the same configuration files for IoTDB DataNode and Standalone version, all under the `conf`.
+
+* `datanode-env.sh/bat`：Environment configurations, in which we could set the memory allocation of DataNode and Standalone.
+
+* `iotdb-system.properties`：IoTDB system configurations.
+
+## Hot Modification Configuration
+
+For the convenience of users, IoTDB provides users with hot modification function, that is, modifying some configuration parameters in `iotdb-system.properties` during the system operation and applying them to the system immediately. 
+In the parameters described below, these parameters whose way of `Effective` is `hot-load` support hot modification.
+
+Trigger way: The client sends the command(sql) `load configuration` or `set configuration` to the IoTDB server.
+
+## Environment Configuration File（datanode-env.sh/bat）
+
+The environment configuration file is mainly used to configure the Java environment related parameters when DataNode is running, such as JVM related configuration. This part of the configuration is passed to the JVM when the DataNode starts.
+
+The details of each parameter are as follows:
+
+* MEMORY\_SIZE
+
+|Name|MEMORY\_SIZE|
+|:---:|:---|
+|Description|The minimum heap memory size that IoTDB DataNode will use when startup |

+|Effective|After restarting system|
+
+## JMX Authorization
+
+We **STRONGLY RECOMMENDED** you CHANGE the PASSWORD for the JMX remote connection.
+
+The user and passwords are in ${IOTDB\_CONF}/conf/jmx.password.

+| Description | IoTDB's strategy for selecting directories for TsFile in tsfile_dir. You can use a simple class name or a full name of the class. The system provides the following three strategies: <br>1. SequenceStrategy: IoTDB selects the directory from tsfile\_dir in order, traverses all the directories in tsfile\_dir in turn, and keeps counting;<br>2. MaxDiskUsableSpaceFirstStrategy: IoTDB first selects the directory with the largest free disk space in tsfile\_dir;<br>You can complete a user-defined policy in the following ways:<br>1. Inherit the org.apache.iotdb.db.storageengine.rescon.disk.strategy.DirectoryStrategy class and implement its own Strategy method;<br>2. Fill in the configuration class with the full class name of the implemented class (package name plus class name, UserDfineStrategyPackage);<br>3. Add the jar file to the project. |

+### Metric Configuration
+
+## Enable GC log
+
+GC log is off by default.
+For performance tuning, you may want to collect the GC info. 
+
+To enable GC log, just add a parameter "printgc" when you start the DataNode.
+
+```bash
+nohup sbin/start-datanode.sh printgc >/dev/null 2>&1 &
+```
+Or
+```cmd
+sbin\start-datanode.bat printgc
+```
+
+GC log is stored at `IOTDB_HOME/logs/gc.log`.
+There will be at most 10 gc.log.* files and each one can reach to 10MB.

+# DataNode 配置参数
+
+IoTDB DataNode 与 Standalone 模式共用一套配置文件，均位于 IoTDB 安装目录：`conf`文件夹下。
+
+* `datanode-env.sh/bat`：环境配置项的配置文件，可以配置 DataNode 的内存大小。
+
+* `iotdb-system.properties`：IoTDB 的配置文件。
+
+## 热修改配置项
+
+为方便用户使用，IoTDB 为用户提供了热修改功能，即在系统运行过程中修改 `iotdb-system.properties` 中部分配置参数并即时应用到系统中。下面介绍的参数中，改后 生效方式为`热加载`
+的均为支持热修改的配置参数。

+若要打开 GC 日志，则需要在启动 IoTDB Server 的时候加上"printgc"参数：
+
+```bash
+nohup sbin/start-datanode.sh printgc >/dev/null 2>&1 &
+```
+
+或者
+
+```bash
+sbin\start-datanode.bat printgc
+```
+
+GC 日志会被存储在`IOTDB_HOME/logs/gc.log`. 至多会存储 10 个 gc.log 文件，每个文件最多 10MB。

+### Metric 配置
+
+## 开启 GC 日志
+
+GC 日志默认是关闭的。为了性能调优，用户可能会需要收集 GC 信息。
+若要打开 GC 日志，则需要在启动 IoTDB Server 的时候加上"printgc"参数：
+
+```bash
+nohup sbin/start-datanode.sh printgc >/dev/null 2>&1 &
+```
+
+或者
+
+```bash
+sbin\start-datanode.bat printgc
+```
+
+GC 日志会被存储在`IOTDB_HOME/logs/gc.log`. 至多会存储 10 个 gc.log 文件，每个文件最多 10MB。

+### Metric 配置
+
+## 开启 GC 日志
+
+GC 日志默认是关闭的。为了性能调优，用户可能会需要收集 GC 信息。
+若要打开 GC 日志，则需要在启动 IoTDB Server 的时候加上"printgc"参数：
+
+```bash
+nohup sbin/start-datanode.sh printgc >/dev/null 2>&1 &
+```
+
+或者
+
+```bash
+sbin\start-datanode.bat printgc
+```
+
+GC 日志会被存储在`IOTDB_HOME/logs/gc.log`. 至多会存储 10 个 gc.log 文件，每个文件最多 10MB。

+### Metric 配置
+
+## 开启 GC 日志
+
+GC 日志默认是关闭的。为了性能调优，用户可能会需要收集 GC 信息。
+若要打开 GC 日志，则需要在启动 IoTDB Server 的时候加上"printgc"参数：
+
+```bash
+nohup sbin/start-datanode.sh printgc >/dev/null 2>&1 &
+```
+
+或者
+
+```bash
+sbin\start-datanode.bat printgc
+```
+
+GC 日志会被存储在`IOTDB_HOME/logs/gc.log`. 至多会存储 10 个 gc.log 文件，每个文件最多 10MB。

+### Metric 配置
+
+## 开启 GC 日志
+
+GC 日志默认是关闭的。为了性能调优，用户可能会需要收集 GC 信息。
+若要打开 GC 日志，则需要在启动 IoTDB Server 的时候加上"printgc"参数：
+
+```bash
+nohup sbin/start-datanode.sh printgc >/dev/null 2>&1 &
+```
+
+或者
+
+```bash
+sbin\start-datanode.bat printgc
+```
+
+GC 日志会被存储在`IOTDB_HOME/logs/gc.log`. 至多会存储 10 个 gc.log 文件，每个文件最多 10MB。
