BKVM - Visual Manager for Apache BookKeeper

Bookkeeper Visual Manager is an open source visual interface for Apache Bookkeeper.

Features:

• Connect to a BookKeeper cluster (4.7+)
• Discover bookies and bookie status
• Search ledgers, using ledger metadata
• Inspect ledger metadata

Usecases:

• Inspect your BookKeeper cluster
• Check health of Bookies
• See which applications are using more resources
• Validate configuration of each application (check replication)
• See Clusterwide configuration

Roadmap:

• Support multi user access, multitenancy and multiple clusters
• Manage Bookies
• Manage replication
• Verify consistency of cluster
• Add advanced query functions
• Add API

Overview

Log in

Use the default account (admin) and the default password (admin) to log in.

Bookies status

Bookies availability (AVAILABLE, DOWN, READONLY) and disk usage.

Ledgers monitoring

Search for specific ledgers and ledgers metadata. Monitor ledger disk usage and replication factor.

Bookies configuration

Quickstart

Requirements

In order to run BookKeeper Visual Manager you just need a Unix Machine and Java 8 runtime.

In order to develop BookKeeper Visual Manager you need Maven 3.6.x and Yarn.

Using the provided release packages

Download a release package from github releases page. Unzip the package

Configure the service by editing conf/server.properties By default we will connect to ZooKeeper at localhost, like when you are using BookKeeper standalone.

Start the service

bin/service server start

Open your browser at http://localhost:4500

Username and passwords are: admin/admin

Deploy the war application using Maven Jetty Plugin

git clone https://github.com/diennea/bookkeeper-visual-manager.git
cd bookkeeper-visual-manager
mvn clean install -DskipTests

To pass the Metadata Service URI connection string you have to set the system property bookkeeper.visual.manager.metadataServiceUri or run the provided script in bin folder.

BVM_PORT=8080
BVM_SERVICEURI=zk+null://localhost:2181/ledgers

./bin/run_dev.sh $BVM_SERVICEURI $BVM_PORT

Deploy the war application on container

You can also deploy the target/bookkeeper-visual-manager-XX.XX.war on your container passing the bookkeeper.visual.manager.metadataServiceUri location in a system property.

Deploy the war application using Maven Jetty Runner

Download the jetty-runner jar available at Maven Central.

BVM_PORT=8080
BVM_WAR_PATH=path/to/warfile

# Environment Variable configuration
BVM_CONF_PATH=/path/to/conf java -jar jetty-runner.jar $BVM_WAR_PATH --port $BVM_PORT

Advanced configuration

In order to use a more advanced configuration you need to provide to the application a key/value properties file. An example file is provided in the conf/ folder. The provided file can also be your Bookkeeper Server configuration.

Property	Value
metadataServiceUri	Location of the Bookkeeper Server.
zkConnectionTimeout	First connection timeout.
zkTimeout	Zookeeper session timeout.

You can provide this file to the application in three ways:

1. System Property: bookkeeper.visual.manager.config.path

   BVM_PORT=8080
   BVM_CONF_PATH=path/to/warfile
   
   mvn jetty:run \
       -Dbookkeeper.visual.manager.config.path=$BVM_CONF_PATH \
       -Djetty.http.port=$BVM_PORT
   

2. Environment Variable: BVM_CONF_PATH

   BVM_PORT=8080
   BVM_WAR_PATH=path/to/warfile
   
   BVM_CONF_PATH=path/to/conf java -jar jetty-runner.jar $BVM_WAR_PATH --port $BVM_PORT
   

3. Deployment Descriptor: bookkeeper.visual.manager.config.path in the web.xml

   <context-param>
       <param-name>bookkeeper.visual.manager.config.path</param-name>
       <param-value>path/to/file</param-value>
   </context-param>
