Workbench Deployment

The visualization console is one of the supporting tools for IoTDB (similar to Navicat for MySQL). It is an official application tool system used for database deployment implementation, operation and maintenance management, and application development stages, making the use, operation, and management of databases simpler and more efficient, truly achieving low-cost management and operation of databases. This document will assist you in installing Workbench.

Installation Steps

Step 1: IoTDB enables monitoring indicator collection

Open the monitoring configuration item. The configuration items related to monitoring in IoTDB are disabled by default. Before deploying the monitoring panel, you need to open the relevant configuration items (note that the service needs to be restarted after enabling monitoring configuration).

Configuration	Located in the configuration file	Description
cn_metric_reporter_list	conf/iotdb-system.properties	Please add this configuration item to the configuration file and set the value to PROMETHEUS
cn_metric_level		Please add this configuration item to the configuration file and set the value to IMPORTANT
cn_metric_prometheus_reporter_port		Please add this configuration item to the configuration file to maintain the default setting of 9091. If other ports are set, they will not conflict with each other
dn_metric_reporter_list	conf/iotdb-system.properties	Please add this configuration item to the configuration file and set the value to PROMETHEUS
dn_metric_level		Please add this configuration item to the configuration file and set the value to IMPORTANT
dn_metric_prometheus_reporter_port		Please add this configuration item to the configuration file and set it to 9092 by default. If other ports are set, they will not conflict with each other
dn_metric_internal_reporter_type		Please add this configuration item to the configuration file and set the value to IOTDB
enable_audit_log	conf/iotdb-system.properties	Please add this configuration item to the configuration file and set the value to true
audit_log_storage		Please add this configuration item in the configuration file, with values set to IOTDB and LOGGER
audit_log_operation		Please add this configuration item in the configuration file, with values set to DML,DDL,QUERY

Restart all nodes. After modifying the monitoring indicator configuration of three nodes, the confignode and datanode services of all nodes can be restarted:

./sbin/stop-standalone.sh      #Stop confignode and datanode first
./sbin/start-confignode.sh  -d #Start confignode
./sbin/start-datanode.sh  -d   #Start datanode

After restarting, confirm the running status of each node through the client. If the status is Running, it indicates successful configuration:

Step 2: Install and configure Prometheus

Download the Prometheus installation package, which requires installation of V2.30.3 and above. You can go to the Prometheus official website to download it (https://prometheus.io/docs/introduction/first_steps/)
Unzip the installation package and enter the unzipped folder:
```
tar xvfz prometheus-*.tar.gz
cd prometheus-*
```

Modify the configuration. Modify the configuration file prometheus.yml as follows

Add configNode task to collect monitoring data for ConfigNode
Add a datanode task to collect monitoring data for DataNodes

global:
scrape_interval: 15s 
evaluation_interval: 15s 
scrape_configs:
- job_name: "prometheus"
    static_configs:
    - targets: ["localhost:9090"]
- job_name: "confignode"
    static_configs:
    - targets: ["iotdb-1:9091","iotdb-2:9091","iotdb-3:9091"]
    honor_labels: true
- job_name: "datanode"
    static_configs:
    - targets: ["iotdb-1:9092","iotdb-2:9092","iotdb-3:9092"]
    honor_labels: true

Start Prometheus. The default expiration time for Prometheus monitoring data is 15 days. In production environments, it is recommended to adjust it to 180 days or more to track historical monitoring data for a longer period of time. The startup command is as follows:
```
./prometheus --config.file=prometheus.yml --storage.tsdb.retention.time=180d
```
Confirm successful startup. Enter in browser http://IP:port Go to Prometheus and click on the Target interface under Status. When you see that all States are Up, it indicates successful configuration and connectivity.

Step 3: Install Workbench

Enter the config directory of iotdb Workbench -<version>
Modify Workbench configuration file: Go to the config folder and modify the configuration file application-prod.properties. If you are installing it locally, there is no need to modify it. If you are deploying it on a server, you need to modify the IP address
Workbench can be deployed on a local or cloud server as long as it can connect to IoTDB
Configuration Before Modification After modification
pipe.callbackUrl pipe.callbackUrl=http://127.0.0.1 pipe.callbackUrl=http://<Workbench's IP address>
Startup program: Please execute the startup command in the sbin folder of IoTDB Workbench -<version> Windows:
```
# Start Workbench in the background
start.bat -d
```
Linux：
```
# Start Workbench in the background
./start.sh -d
```
You can use the jps command to check if the startup was successful, as shown in the figure:
Verification successful: Open "http://Server IP: Port in configuration file" in the browser to access, for example:"http://127.0.0.1:9190" When the login interface appears, it is considered successful

Configuration	Before Modification	After modification
pipe.callbackUrl	pipe.callbackUrl=`http://127.0.0.1`	pipe.callbackUrl=`http://<Workbench's IP address>`

Step 4: Configure Instance Information

Configure instance information: You only need to fill in the following information to connect to the instance

Field Name	Is It A Required Field	Field Meaning	Default Value
Connection Type	Yes	The content filled in for different connection types varies, and supports selecting "single machine, cluster, dual active"	-
Instance Name	Yes	You can distinguish different instances based on their names, with a maximum input of 50 characters	-
Instance	Yes	Fill in the database address (`dn_rpc_address` field in the `iotdb/conf/iotdb-system.properties` file) and port number (`dn_rpc_port` field). Note: For clusters and dual active devices, clicking the "+" button supports entering multiple instance information	-
Prometheus	No	Fill in `http://<Prometheus IP address>:<Prometheus port number>/app/v1/query` to view some monitoring information on the homepage. We recommend that you configure and use it	-
Username	Yes	Fill in the username for IoTDB, supporting input of 4 to 32 characters, including uppercase and lowercase letters, numbers, and special characters (! @ # $% ^&* () _+-=)	root
Enter Password	No	Fill in the password for IoTDB. To ensure the security of the database, we will not save the password. Please fill in the password yourself every time you connect to the instance or test	root

Test the accuracy of the information filled in: You can perform a connection test on the instance information by clicking the "Test" button
