Cisco LiveData is the next generation reporting product for
Cisco Unified Contact Center Enterprise (CCE).  Cisco
LiveData provides a horizontally scalable, highly available
architecture to support systems with large numbers of
reporting users.  LiveData enables fast refresh rates on
real-time data (3 seconds or less).  A LiveData node consumes
real-time data streams from one or more sources, processes
the data and publishes the resulting data to solution
consumers.  Consumers may be database management systems,
applications or reporting engines.
        
Cisco LiveData aggregates and publishes real-time data and
metrics pushed to it (e.g. from the CCE router and/or
peripheral gateway components) to a message bus; Cisco
Unified Intelligence Center (CUIC) and the CCE Administrator
Workstation (AW) subscribe to this message bus to receive
real-time data updates.  CUIC users then build reports using
this real-time data; other CCE clients may also query this
real-time data from the CCE AW database.
        
A LiveData cluster consists of one or more nodes; one is
designated as the master with additional worker nodes as
needed.  A LiveData cluster may have a remote peer cluster
that works cooperatively in a fault-tolerant model.  LiveData
cluster peers communicate with one another to negotiate who
is the 'active' cluster and who is on 'standby' (only one
cluster will be active at a time).  If the active cluster
fails, the standby cluster will transition to active and
begin consuming the data streams previously consumed by the
peer cluster.
        
In small deployments, a LiveData cluster will be collocated
with CUIC in the same server virtual machine; in larger
deployments, a LiveData cluster may include several nodes
that may or may not be collocated with CUIC.
        
A single node in a LiveData cluster will have multiple
services running in the guest virtual machine that are
critical to the successful function of that node.  Services
may be distributed across the nodes of a cluster to balance
the workload.  Each node will establish and maintain
connections to data sources in the solution.
        
CISCO-LIVEDATA-MIB defines instrumentation unique to the
LiveData servers (virtual machines). The instrumentation
includes objects of:
    1) a general nature - attributes of the device and
       application,
    2) cluster status* and identity,
    3) service status and identity and
    4) connection status and attributes (including metrics).
    5) events
        
* It is important to note that cluster status is shared
across all nodes of a cluster; cluster status is not
device-specific unless there is only one node in the cluster.
        
The MIB also defines a single notification type; all nodes in
all clusters may emit notifications.
        
Service and connection instrumentation is exposed as tables.
The number of entries within each table may change over time,
adapting to changes within the cluster.
