Description

Cookbook for Java Management and Monitoring (JMX, trusted certificates, SNMP, etc.)

Requirements

Platforms

• CentOS 6
• RedHat 6

Cookbooks

Required Opscode Cookbooks

• java

Attributes

These attributes are under the node['java-management'] namespace.

JMX Attributes

These attributes are under the node['java-management']['jmxremote'] namespace.

SNMP Attributes

These attributes are under the node['java-management']['snmp'] namespace.

Truststore Attributes

These attributes are under the node['java-management']['truststore'] namespace.

Data Bags

JMX/SNMP Management Encrypted Data Bag

java/management encrypted data bag:

• ['roles'] - required if you enable default JMX configuration
  • ['name'] - JMX role name
  • ['access'] - "readonly"/"readwrite"
  • ['password'] - password for role
• ['acls'] - required if you enable default SNMP configuration
  • ['communities'] - array of SNMP community names
  • ['access'] - "read-only"/"read-write"
  • ['managers'] - array of hostnames/CIDR addresses with access
• ['traps']
  • ['trap-community'] - SNMP trap community name
  • ['hosts'] - array of hostnames/CIDR addresses to send SNMP traps

Truststore Data Bag

node['java-management']['truststore']['data_bag'] data bag (defaults to java_truststore), with data bag items:
* ['id'] - Trusted certificate alias
* ['certificate'] - Trusted certificate contents
* Other options as accepted by truststore_certificate LWRP

Recipes

• recipe[java-management] Empty recipe for LWRPs
• recipe[java-management::management] Configures Java JMX and SNMP
• recipe[java-management::truststore] Configures Java truststore

LWRPs

java_management_truststore_certificate

Import trusted certificate into Java truststore

Example:

java_management_truststore_certificate "alias" do
  file "/path/to/certificate"
end

Usage

Add Trusted Certificates

If the certificate files are already on the filesystem:

• Add {certalias => options} to node['java-management']['truststore']['certificate_files']
  • options (as a String) certificate file location
  • options (as a Hash)
  • file required certificate file location
  • Other options accepted by truststore_certificate LWRP

If you'd like to use data bag items (data bag defined by node['java-management']['truststore']['data_bag']):

• knife data bag create java_truststore my_cert
• Create at least certificate attribute with certificate contents and save

If you'd like to use the LWRP directly:

java_management_truststore_certificate "alias" do
  file "/path/to/certificate"
end

Password secured remote JMX setup without SSL

• knife data bag create java
• knife data bag edit java management --secret-file=path/to/secret
• Set ['roles'] with at least one role in encrypted data bag
• Set node['java-management']['local_only'] attribute to false
• Set node['java-management']['port'] attribute
• Set node['java-management']['ssl'] attribute to false
• Add recipe[java-management::management] to run_list
• Configure JAVA_OPTS to include one of the following:
  • recommended -Dcom.sun.management.config.file (example: =$JAVA_HOME/jre/lib/management/management.properties)
  • -Dcom.sun.management.jmxremote.port
• Restart Java service and watch for configuration errors

ACL secured remote SNMP

• knife data bag create java
• knife data bag edit java management --secret-file=path/to/secret
• Set ['acls'] with at least one ACL in encrypted data bag
• Set node['java-management']['interface'] attribute to "0.0.0.0"
• Set node['java-management']['port'] attribute
• Add recipe[java-management::management] to run_list
• Configure JAVA_OPTS to include one of the following:
  • recommended -Dcom.sun.management.config.file (example: =$JAVA_HOME/jre/lib/management/management.properties)
  • -Dcom.sun.management.snmp.port
• Restart Java service and watch for configuration errors

Testing and Development of this Cookbook

Here's how you can quickly get testing or developing against the cookbook thanks to Vagrant and Berkshelf.

gem install bundler --no-ri --no-rdoc
git clone ssh://git@github.com:bflad/chef-java-management.git
cd java-management
bundle install
bundle exec vagrant up BOX # BOX being centos6 or ubuntu1204

You can then SSH into the running VM using the vagrant ssh command.
The VM can easily be stopped and deleted with the vagrant destroy
command. Please see the official Vagrant documentation
for a more in depth explanation of available commands.

Contributing

Please use standard Github pull requests and if possible, in combination with testing on the Vagrant boxes.
