From OpenNMS

Distrubuted Pollers ToDos

• Make a webstart app
• Put webstart app buliding in the build
• Pull the appropriate poller pieces apart from the whole of opennms
• figure out communications with the main part of opennms
• figure out how to pass a configuration to a remote poller

Distributed Monitor Use Case Ideas

Terminology/Model

✓Medical Center == Monitoring Area
✓Facility == Monitoring Location == Monitoring System == Remote Poller
Application == External App == Monitored App
check == test == 


Proposed:

<!--THIS IS GOOD -->
MonitoredApplication
   defined by a collection of monitoredServices

MonitoringLocationDefinition


LocationMonitor instanceof MonitoringLocationDefinition
LocationMonitor monitors 'a collection of monitoredServices'


LocationSpecificStatusChange
	LocationMonitor
	MonitoredService
         PollStatus

User View Use Cases

1. Summary of Monitored

Need to show a table of all LocationMonitors and the computed aggregated status of each MonitoredApplication
from the perspective of the LocationMonitor

Input: none

Output: 

Summary Table
For each LocationMonitor
- The 'Area' attribute of the MonitoredLocationDefinition for this LocationMonitor
- The 'Name' attribute of the MonitoredLocatoinDefinition for this LocationMonitor
- A cell containing for each MonitoredApplication that has the following attributes:
  -   The contents of the cell contains the number of intervals in the last 24 hours in
      which all monitoredServices for that Location monitor are UP diveded by the total
      number of intervals written as a percentage
  - The color of the cell is as follows:
       Green all monitorServices for the LocationMonitor are up
       Yellow at least one monitoredService for the LocationMonitor is in warning state but none are in failure state
       Red at least one monitoredService for the LocatoinMonitor is in failed state
       Blue the LocationMonitor has failed to report in / is unavailable

2. History

Show the response time history for the MonitorServices of a given MonitoredApplicatoin over a given time span from the perspective of a given LocationMonitor

Input:

A LocationMonitor id, an MonitoredApplicationId id, a timeframe, and a subset of the intersection between the set of monitoredServices belonging to the LocationMonitor and the set of monitoredServices belonging to the MonitoredApplication

Output:
A GraphPage that contains:
- The current LocationMonitor
- The current MonitoredApplication
- The current Timespan
- The list of requested MonitoredServices
- A list of Graphs each containing a url to a responseTime graph as described in 3.

3. Create a graph image for the responseTime from a given LocationMonitor

Input:
  LocationMonitor
  MonitoredService
  Constraint: The monitoredService must be a monitoredService for that LocationMonitor

Output:
   Graph Image of responseTime for that monitoredServices as reported by that LocationMonitor

4. CurrentStatus page

Show the current status of a given MonitoredApplication from the perspective of a given LocationMonitor including reponseTime

Input:
A LocationMonitor and a MonitoredApplication

Output:
A table of current results returned from the LocationMonitor for monitoredServices that belong to the MonitoredApplication



5. Define/Configure a new MonitoredApplication

Some way to define the set of monitored services associated with a MonitoredApplication

6. Define/Configure a new MonitoringLocationDefinition
Define/Configure the polling configuration associated with a MonitoredLocationDefinition

Set the 'Area' for a MonitoringLocationDefinition
set the 'Name' of the MonitoredLocationDefinition
Set up the details for what MonitoredServices should be associated with LocationMonitors for the MonitoredLocationDefinition
