Web Management Console
The Web Management Console is a web application that enables users to quickly understand the state of a running data grid cluster and monitor the running components, such as the physical hosts, JVMs and deployed Processing Units.
This user interface complements the GigaSpaces Management Center and provides a lightweight alternative for monitoring a running cluster, without having to install the GigaSpaces runtime and run the standalone Java-based user interface.
The Web Management Console application is located under
<product>/tools/gs-webui. This directory contains the web application itself (in the form of a standard JEE .WAR file), and a launcher library and shell scripts used to start it in standalone mode (see below).
Starting the Web Management Console on a Local Machine
When you first start using GigaSpaces or GigaSpaces, you may prefer to run the Web Management Console on your local machine instead of on a web server. Simply click the
gs-webui.sh(bat) script to start a Jetty web container with the Web Management Console application running within it. After the user interface starts, there's no need to deploy or perform any additional steps.
In standalone mode, the web container listens by default on port 8099. To view the Web Management Console point your browser to
http://<standalone server host>:8099, where
<standalone server host> is the host on which you launched the
gs-webui script. In this mode, the default context path for the Web Management Console is the root context path ("/").
The Web Management Console (Web-UI) allows for a secured access when the security
enabled property is set. This property should be configured using
GS_OPTIONS_EXT in the
setenv script and is applied to all GigaSpacesGrid Components.
The Lookup groups and Locators are loaded from the
setenv/setenv-overrides script. They can be configured via the configuration files described in Configuring the Environment Variables.
Additionally, if the Web Management Console is secured, it automatically signs out the user if there is no activity for a defined period of time. The default timeout is 10 minutes, which can be changed using the
-Dcom.gs.web-ui.idle-session-timeout system property (the time unit is seconds).
Security Properties File
The security properties file is used to configure the
SecurityManager, which is responsible for the authentication and authorization process. The
security.properties file is common to all components and is usually located under
<product>/config/security/security.properties. To only affect the Web Management Console, use
The configuration file can be located anywhere in the classpath or in the classpath under
config/security. Alternatively, a system property can be set to indicate the location of the properties file:
-Dcom.gs.security.properties-file = my-security.properties
-Dcom.gs.security.properties-file the property file will be located as a direct path (e.g.
a resource (e.g. "my-security.properties") in the classpath or in the classpath under
An authentication mechanism might require a different set of actions to be taken on the provided credentials (username/password). A custom extension can be provided for this, as described in the Authentication page of the Security section.
This credentials provider is configured as arguments to the command line of the Web Management Console. Use
-user-details-provider for the provider class name. Use
-user-details-properties to provide additional properties. This argument is optional.
gs-webui script with these parameters:
gs-webui(.sh/bat) -user-details-provider com.demo.CustomCredentialsProvider -user-details-properties custom-security.server-address=myServer
In order to run the Web Management Console server with SSL ( using the HTTPS protocol instead of HTTP), the following parameters must be provided as arguments to the
ssl.keyManagerPassword- Password (if any) for the specific key within the key store.
ssl.keyStorePassword- Password for the key store.
ssl.keyStorePath- File or URL of the SSL Key store.
ssl.trustStorePath- File name or URL of the trust store location.
ssl.trustStorePassword- Password for the trust store.
#Specify SSL via a command line argument ./gs-webui.sh -ssl.keyManagerPassword <passw> -ssl.keyStorePassword <passw> -ssl.keyStorePath <key-store-path> -ssl.trustStorePath <trust-store-path> -ssl.trustStorePassword <passw>
#Specify SSL via a command line argument gs-webui.bat -ssl.keyManagerPassword <passw> -ssl.keyStorePassword <passw> -ssl.keyStorePath <key-store-path> -ssl.trustStorePath <trust-store-path> -ssl.trustStorePassword <passw>
You can also use the
WEBUI_JAVA_OPTIONS environment variable to set any JVM parameter, such as heap size (defaults to
-Xmx512m) and other JVM settings.
In order to disable anonymous login, use
com.gigaspaces.webui.username.mandatory system property. The following example shows how to do this:
#Specify user name field as mandatory export USER_NAME_MANDATORY=true ./gs-webui.sh
#Specify user name field as mandatory set USER_NAME_MANDATORY=true gs-webui.bat
Deploying the Web Application
When you reach the stage of a proper deployment, or are preparing to move to production, you can deploy the Web Management Console as described below.
GigaSpaces Runtime Environment
To deploy the Web Management Console to the GigaSpaces Runtime Environment, point your deployment tool of choice (CLI, Admin API or the GigaSpaces Management Center) to the
<product>/tools/gs-webui/gs-webui.war file and deploy it.
In this case, the Web Management Console actually monitors the runtime environment on which it runs.
The following example shows how to do this using the GigaSpaces CLI:
$GS_HOME/bin/gs.sh(bat} deploy -properties embed://web.port=80;web.context=/ $GS_HOME/tools/gs-webui/gs-webui.war
The above command deploys the Web Management Console to the GigaSpaces runtime environment, listening on port 80 with the root context path.
For more information about GigaSpaces's web application support, refer to the Web Application Support section in the Developer Guide.
Third-Party JEE Servlet Container
You can deploy the Web Management Console to a third-party servlet container, for example, Apache Tomcat (must be Tomcat 8 and above in order to support Java 8). Consult your web container documentation for deployment instructions.
When deploying to a third-party web container like Apache Tomcat, you must repackage the
xap-webui-[version-build].war file and add the following .JAR files to the
WEB-INF/lib directory of the
.jarfiles located under
By default, these are not part of the the
gs-webui.war file because they are automatically included in the classpath of both the standalone container and the GigaSpaces Runtime Environment.
After the web application starts, point your browser to the proper location. For example, if you start the web application using a standalone web container, the default URL is
http://<standalone server host>:8099.
You will see the following screen:
Supported Web Browsers
The Web Management Console supports the following web browsers:
- Moziila Firefox 11 or higher
- Google Chrome 18 or higher
- Microsoft Internet Explorer 10 or higher
Deployment Location of the Web Application
The web application communicates with the runtime components of the data grid cluster, and receives notification from the lookup service. Therefore, it is highly recommended to run the web application in the same network segment of the other cluster components. This does not affect the web browser client, which communicates with the web application using standard HTTP and can be located anywhere, provided that it has access to the web application.
Running via a Reverse Proxy
YOu can set up a reverse proxy for the Web Management Console. This may be preferable in certain scenarios, such as when access to the Web Management Console is done via a gateway. Reverse proxy setups are currently available and tested only on the Apache web server.
Configuring the Proxy
Enable the relevant modules, by uncommenting (or adding) the following lines inside
LoadModule proxy_module modules/mod_proxy.so LoadModule proxy_http_module modules/mod_proxy_http.so
Add your server's name, and define a virtual host for the configuration, where
gs.webui.com represents your server's DNS:
NameVirtualHost *:80 <VirtualHost *:80> ServerName gs.webui.com </VirtualHost>
Create mappings to channel proxy paths (
webui-endpoint being the proxied path obscuring the address of the Web Management Console):
<VirtualHost *:80> ... ProxyPass /webui-endpoint/ http://127.0.0.1:8099/ ProxyPassReverse /webui-endpoint/ http://127.0.0.1:8099/ ProxyPreserveHost on </VirtualHost>
Set a redirection rule for serving the login page:
<VirtualHost *:80> ... RedirectMatch /Gs_webui.html /webui-endpoint/Gs_webui.html </VirtualHost>
Debugging Your Proxy
You can dump logging information to custom files on the Apache server by adding the following rules:
<VirtualHost *:80> ... ErrorLog "logs/webui-error_log" CustomLog "logs/webui-access_log" common </VirtualHost>
For more information on Apache's reverse proxy configuration, refer to the corresponding entry on the Apache Tutor website.
Customizing the Configuration Options
The Web Management Console has an out-of-the-box default configuration that can be used with any standard environment. However, when preparing for deployment, you may want to customize certain configuration options to suit your specific organization needs.
Localizing the User Interface
In addition to the default English, the Web Management Console supports localization to Chinese. You can define the language in which the user interface is displayed by either creating a new configuration file, or modifying the existing configuration file.
Creating a New Configuration File
Create a new XML file with the following contents:
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <import resource="classpath:xap-webui-context.xml" /> <bean id="localeConf" class="com.gigaspaces.admin.webui.shared.beans.LocaleConf"> <property name="name" value="LOCALE"/> </bean> </beans>
LOCALEvalue with the required language code (
Save the file under $GS_HOME/config.
Pass this file as a system property to the Web Management Console launcher script, as follows:
# specify the locale context location export WEBUI_JAVA_OPTIONS=-Dcom.gs.webui.context=classpath:config/locale.xml # launch the web UI bin/gs-webui.sh
:: specify the locale context location set WEBUI_JAVA_OPTIONS=-Dcom.gs.webui.context=classpath:config/locale.xml :: launch the web UI bin\gs-webui.bat
Updating the Existing Configuration File
- Open the xap-webui-[version-build].war archive (located under
$GS_HOME/tools/gs-webui) for exploring and navigate to
Edit the web-context.xml file to add the
localeConfbean with the desired language (
zh_CNfor Chinese or
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <import resource="classpath:webui-context.xml" /> ... <bean id="localeConf" class="com.gigaspaces.admin.webui.shared.beans.LocaleConf"> <property name="name" value="zh_CN"/> </bean> </beans>
Specifying a Custom Port
To override the default port, you can either use the
org.openspaces.launcher.port system property (by defining WEBUI_PORT variable), or specify
-port <listen port> as an argument to the
gs-webui script. Here is an example on how it's done (starting to listen on port 80):
#Specify port via a command line argument ./gs-webui.sh -port 80 #Specify port with a system property export WEBUI_PORT=80 ./gs-webui.sh
#Specify port via a command line argument gs-webui.bat -port 80 #Specify port with a system property set WEBUI_PORT=80 gs-webui.bat
Binding to a Specific Host
To bind to specific host, you can either use the
org.openspaces.launcher.bind-address system property (by defining BIND_ADDRESS variable), or specify
-bind-address <myhost> as an argument to the
Default used bind address is 0.0.0.0 .
Here is an example on how it's done (starting on host 192.168.10.1):
#Specify bind address via a command line argument ./gs-webui.sh -bind-address 192.168.10.1 #Specify bind address with a system property export BIND_ADDRESS=192.168.10.1 ./gs-webui.sh
#Specify bind address via a command line argument gs-webui.bat -bind-address 192.168.10.1 #Specify bind address with a system property set BIND_ADDRESS=192.168.10.1 gs-webui.bat
Operational Statistics Configuration
The Web Management server uses the Administration API to collect the operational statistics that are displayed in the Web Management Console. By default the Admin instance collects only two kinds of statistics, Space and SpaceInstance. These are the only other statistics that can be viewed using the Web Management Console.
The statistics are sampled and aggregated for display in the throughput statistics timeline based on the
com.gs.space.history-size system property. The default value is 15 samples. Other statistics are not collected because there is no means of displaying the results.
To change the amount of samples that are aggregated, modify the system property as follows (only the
com.gs.space.history-size parameter is relevant):
For information about how to view the Space statistics in the Web Management Console, see the Viewing Space Statistics topic.
