A significant difference in approach was the initial approach to expose the Local interfaces nearly completely.  In this second go there is a goal to provide a smaller set of Remote interfaces that remain robust yet are easier to use for the vast majority of integration use cases.  It will de-emphasize administration and focus on operational aspects of integration. This set of remopte interfaces must support the CLI, as well as support as many of our known use cases as possible.  A more general goal is to be able to build powerful applications, both automation and GUI oriented, on this set of services.  Although, it is not the goal to be able to implement the full JON GUI on this set of services.
These remote interfaces will be made available via JBoss Remoting for Java clients, and JAX-WS (JBossWS) for non-Java clients (although nothing prevents a Java WS client as well, it's just not obvious what the need would be given JBoss remoting).
Proposed Remote Interface:

  • Utilize the current SLSB impls while providing a more consistent, convenient, and cohesive remote interface. (the locals can be too specific to the RHQ GUI and show signs of organic growth)
  • Simmplify API by providing simple services for common requests complemented by rich, multi-purpose counterparts for complex needs (various, optional params)
  • Prefer paginated services with "Subject" parameter (noted where Subject was added)
  • Carefully consider the needs for Administration services
    • We'll have to carefully consider CRUD.  I expect that certain Add/Create services will be needed. Not sure of the use cases. Delete/Purge probably less so.

Use Cases

The use cases give a more detailed idea of what the API must offer. Based on the existing use cases following lists summarize the current requirements:

Goals Summary

  • Authenticated sessions
  • Authorized services
  • Export/Read-Only focus
  • Resource and Group Level services
  • Operational control (i.e. Operation execution)
  • Live/Current metric data
  • User management
  • Deployment

Non-Goals Summary

  • Most Administration
    • Content
    • HA
    • Template
    • Role
  • Group Definition/Creation
    • Dyna-Group Calculation
  • Configuration update
  • Inventory import/add/uninventory/delete

Applicable to all use cases:

  • login/logout will start/end all service interaction
  • resources includes resource groups where applicable

Use Case #1 - JBossAS Activation

  1. find a JBossAS resource of interest
  2. start/stop/restart the JBossAS resource

Use Case #2 - Export Alerts

  1. find resource(s) of interest
  2. get Alert History

Use Case #3 - Configuration Management

  1. find resources or plugins of interest
  2. get the current configuration
  3. Update the configuration

Use case #4 - Export current (live) Numeric or Trait metric data

  1. find resources of interest
  2. get the current metric data

Use Case #5 - Export Event data

  1. find resources of interest
  2. get event history

Use case #6 - Support the CLI

The CLI should be able to leverage the remote API as a remote client. Use cases of the CLI are therefore also candidates for use cases of the remote API.

Use case #7 - User management / LDAP Integration

Priority: High

  1. check user existence
  2. add user
  3. optionally, perform password mgmt
  4. assign to existing roles
    or
  5. delete user
    or update user

Use case #8 - Deployment

Source: M. Dickson

  1. Support CLI-based or direct deployments of ear/war/jar/scripts

Additional (Joe's)automate the import / ignore process

always want to import all jboss-as
always want to ignore certain other servers that may be running
come up with that forumla, then script it as each new box is added
also, be able to rename according to some internal conventions to make identification easier wrt infrastructure
need to expose connection properties as well as query for machine traits

sla reporting
figure out the percentage downtime across the enterprise / each box / each server

flexible alert notifications
today we don't implement "send me emails once / hr containing all alerts that have triggered"
integration with EmailManagerBean

system activity
query all BLAH created in the last X timeframe, groupby user (also support arbitrary timeframes)
BLAH := op defs / alert def / plugin configuration changes / visible groups created

dynagroup enhancements
dynagroups may not support expression to create groups properly (name contains substr1 or substr2)
so resource search and get the dynagroups grouping functionality via scripts
cron the script so as to mimic dynagroup recalculation intervals

ldap integration
new ldap users become new JON users and have roles/perms automatically setup for them
when user leaves ldap, then automatically disable corresponding JON account
how to provide ldap query funcs - ldap plugin, exposed slsb, tell them to use 3rd party api?

scheduled patch rollout
automatically add all resources in some group to a channel
patch a single instance or multiple instances
aggregate the statuses of "group patch" rollout

complex alert actions
execute operation (with arguments) on some arbitrary resource, as a result of an alert
pass some contextual information from the alert into the operation
can we make this simple for alerting on different levels - resource, group, template?

geographic affinity
query agents and group them into affinity based on location, name, subnet, etc
which agents are NOT connected to their primary?
might be indication of network health or unexpected failover events
also, are any agents not reporting back? last heard from time is greater than X

script chaining
instead of having to copy/paste functionality between scripts, allow decomposition
each script does some elemental work, can chain them together during a user session
login script, action script, logout script

dynamic favorites
add to / remove from resource / group / chart favorites based on rules
perhaps machines with ISSUES become favorites so they can easily be identified/worked on by ops
ISSUES := currently down, alerting often, problem metrics

reporting
recently added resources, anything imported in the last day - counts by resource category, resource type, agent, etc
system metrics / min - group by server, group by agent
report hardware summary for each machine, easy to see whether collection frequency is too high given physical limitations

hot-spot metric scheduling
if metric-based alert is triggered, automatically increase frequency of collection for that metric
after a restart, collect metrics quickly until box is proven stable, then decrease collection interval

alert escalation
instead of using notification policy, programmatically send alert email to some user
if "issue" not resolved in X time, send to next user in the list
question - is there a way to integrate this list into the core without too much work?
do escalation policies require us to implement alert ack'ing? (acknowledgements)

follow-the-sun alerting
similar to alert escalation, except that different users are notified depending on what time it is
if alert occurs at 18:00 UCT, notify the US support team, if 10:00 UTC notify the EU support team

maintenance windows
temporarily disable alerts across resource or group according to known maintenance windows
