Command-line based admin tools to make it easier

and faster to administer in production deployments.

Tomcat does not have one currently.




Enterprise-class Java

Application Servers




Issues in Administering

Tomcat• No command line administration tool for

Tomcat• Command line tools are good for resolving

incidents in realtime

• CLI utilities are easily automatable, GUIutilities not-so-much




Image

• Tomcat is perceived by many as a non-enterprisegrade platform, even though it is one (Walmart,Etrade, etc)

• Most of the major enterprise-class Java app serversinclude an automation utility (JBoss Fiddle, Oracle Weblogic WLST, IBM WebSphere)

Building your own tools

• Can be time consuming

• No best practices baked in

• Another thing to maintain

Simplicity and speed are key to managingproduction apps

• Command line tools improve usability

and increase adoption

• Easy to automate

• No time to dig (site or business processtanking)

• Can be integrated with other CM tools

like Puppet, CfengineThursday, November 4, 2010



JMX + Jython (soon to

be Groovy)

• JMX: Java Management Extensions

• Jython: Java implementation in Python

•Groovy (easier to build and deploy)




Current Capabilities

• Getting / setting / invoking Mbeans

• Invoking remote methods

• Simple Unix-like hierarchical interface (cd, ls,

help, invoke, get, set)

• Automation capabilities

•Base framework implemented, features will

come out of the community need

• It’s Fast

•Customizable




Demo




Future Roadmap• Ability to manage and monitor groups of

independent Tomcat servers and Clusters

• Auto-completion of syntax

• Security (SSL/Login)

• Detect Thread Starvation, Aggregate GC Times, Reset counters on a schedule, Servletload times across a group or cluster

• Tomcat 7

• Groovy PortThursday, November 4, 2010



We need your help

• We need feedback and contributors

• Can be used as a framework for more than

Tomcat (Geronimo, Cassandra, Commercial)

• Base framework created, needs rich featuresets next

• Help make Tomcat simpler to manage andautomate for production deployments (andincrease adoption)




Thank you!
