Once a health data is converted to signals using any of the available collection KACs, they are available for use by analysis KACs. Analysis may involve such operations as filtering, aggregation, transformation, statistics analysis and conditional routing.

The following table provides an overview of related Kashef KACs:

KAC	Status	Function
Multiplexer	Available	Adds one or more signals to an existing carrier signal or as part of a new carrier signal. Carrier signals group multiple signals together so that they are transported together across analysis KACs or across KPACs.
DeMultiplexer	Available	Splits an incoming carrier signal into the signals which it's carrying.
Replicator	Available	Clones a given signal into one or more copies for propagation into parallel processing pathways.
Switch	Available	Routes a given signal into a positive or negative path depending on a conditional user defined expression
Filter	Available	Applies a signal filter against all the sub-signals of an input carrier signal. The result is a new carrier signal carrying only the sub-signals matching the user defined expression.
Statistics Analyzer	Available	Applies a running statistical analysis against an input signal or group of signals. A user defined time window determines the running sliding statistical intervals. Statistics include minimum, maximum, average, standard deviation and rate.
OLAP Analyzer	Planned	Provides streaming multi-dimensional analysis capabilities against input signal data.
Group	Available	Performs a specific grouping operation against an input signal hierarchy.
Finite State Machine	Available	Enables analysis scenarios that need to track changes to a given item's state and cause different actions depending on the state changes. For example, an email notification needs to be sent when a service is down and then again when it goes back up.
Transformer	Available	In a analysis context, allows for the creation of a new signal with values based on information from one or more input signals. Transformation rules follow user defined mappings rules represented as C# language expressions. Language Integration Query, which is a feature of C# language, is best used in this context for performing advanced signal processing rules.

Kashef signals whether raw collected signals or processed and transformed signals can be published for use by other systems. This provides a powerful integration facility for systems such as System Center Operations Manager (SCOM) to capture Kashef provided data for specialized reporting and historical storage.

Amongst the KACs supporting this function are:

KAC	Status	Function
Performance Counter Generator	Available	Publishes an incoming a signal into a windows performance counter.
File Logger	Available	Logs incoming signal data to a compact binary log file which can then be post-processed for crude historical trend analysis.
SNMP Generator	Planned	Converts signals to SNMP health data.

Visualization KACs convert data into graphical gauges which act as the building block of a monitoring dashboard.

The following gauges are available:

KAC	Status	Function
Label	Available	Used to display static text on a dashboard.
Picture	Planned	Used to display static background picture on a dashboard.
Health	Available	Provides a visual representation of a signal value along with color switching ability. Example usage would be to show green for healthy component and red for critical conditions. Can also be used to provide drill-down link capability to display other sub-dashboards.
Table	Available	Provides a tabular representation of group of input signals including all the signal metadata and data. Other features include color highlighting depending on input values along with conditional linking ability to other dashboards.
Chart	Available	Translates input signal data to a real-time health chart. Chart formats supported include Trend, Stacked, Column and Pie.

Notification to unattended operators can be accomplished through three KACs:

KAC	Status	Function
Mail Sender	Available	Sends an email through an SMTP gateway. Triggering condition and email content is based on input signals.
SMS Sender	Planned	Sends an sms through an SMSC gateway. Triggering condition and email content is based on input signals.
Transformer	Available	Through its ability to host any user defined C# script, any custom notification logic can be implemented with a Transformer.

Standard Kashef based implementations requires the collaboration of multiple KPacks hosted on different servers. This makes possible a highly scaleable monitoring infrastructure that can span continents in some instances. To make this possible, Kashef provides a variety of KACs to facility inter KPack communication.

These include the following:

KAC	Status	Function
Pipe Sender and Receiver	Available	Allows signals from a sender to be pushed to a receiver on the same machine or another using the Named Pipe Protocol.
HTTP Sender and Receiver	Available	Allows signals from a sender to be pushed to a receiver on the same machine or another using the HTTP Protocol. This communication path can travel through firewalls and http proxies.
TCP Sender and Receiver	Available	Allows signals from a sender to be pushed to a receiver on the same machine or another using the TCP Protocol. This is the most efficient protocol and is used for high the most demanding distributions.
TCP Distributor and Collector	Available	Similar to TCP Sender/Receiver but allows for connections to be established from a tcp client (Collector) to a single distributor who is listening for incoming connections and pushing signals to all connected clients. This mode of communication is ideal for communication with visualization workstations which can be added dynamically without any server reconfiguration.

A Kashef Component Pack is a collection of KACs grouped together to provide a common function. Examples include a SQL Server Collection and KPack, SQL Sever analysis KPack, and an IIS analysis KPack. KPacks are self contained and include all the resources and configuration needed to execute.

Making advanced and complex KPacks possible is the "Integrated Circuit" KAC which acts as a container for other KACs including Integrated Circuits.

Integrated Circuit KACs is a very flexible container which allows templating functionality and can be used to clone an existing module dynamically and increase KPack reusability.

Kashef Packs can be hosted inside a Windows Service or executed in the Kashef Studio. Typically the Studio is only used configuration, debugging and troubleshooting purposes. A windows service host ensures monitoring services are ran as a background process and automatically started if a Server is rebooted. The same tool is used for dashboard navigation.

An easy to use graphical environment provides one tool for defining, revising, testing and running Kashef Packs.

Features include:

• Fully graphically driven workbench for creation and configuration of KACs
• Validation and troubleshooting ability that can pinpoint errors in configuration or dynamic scripts
• Dynamic inspection of signal data as it flows across KACs
• Visualization of dashboards and related Gauges
