Monitis open API and available collection of open source monitoring and management scripts provide nice possibility for finding solutions for monitoring your systems. Still there are many cases when you need a specific monitor and do not have or don’t want to spend much time on coding. That is the reason of presenting the very simple and easy way of building custom monitors with Pentaho Data Integration suite.
Pentaho Data Integration (PDI) – Kettle is a free, open source ETL (Extraction, Transformation and Loading) tool. Along with powerful data extract, transform and load capabilities, Kettle provides intuitive and rich graphical design environment – Spoon. Spoon is a fast and easy way for building applications without writing a code. Drag and drop interface allows to graphically construct transformations and jobs.
In our article we want to present a very simple way of building custom monitor using Spoon. Moreover, our goal today will be monitoring of a business performance data opposite to usual system or application monitoring. Actually monitored data can be any information extracted from your database that needs to be shared and/or monitored. We’ll build a monitor that based on SQL query, will trace test table Orders, randomly populated with data, by order statuses. In this case number of orders grouped by current status (In Process, On Hold, Shipped and Cancelled) will act as metrics for our custom monitor.
To start, please, just have a look at Monitis API documentation. For creating custom monitor we need to implement the steps described below:
1. Authentication – using Monitis API key and secret key (keys are available from your Monitis account: Tools->API) we need to get authentication token that will be used further for creating monitor and posting data.
For that, the following transformation
was created, using transformation steps listed below:
|to provide API url, API key, secret key and other request parameters for API calls|
|HTTP request for Authentication token|
|Json input for parsing result of Authentication token request|
|and selection of needed parameter to be used later|
After testing, we will implement small changes for converting created transformation to sub-transformation by simply adding Input and Output Specification as a start and end steps and removing info about API and secret key from parameters. This information will be provided in main transformations as an input for Authentication sub-transformation. Actually, we have created building block for our next steps which can be used in other transformation without any changes.
Here Data Grid steps are used for providing necessary input information:
|API key and secret key in User data, as an input for Authentication sub-transformation|
|and metrics description|
User Defined Java Expression step and Group By step for constructing parameter list for create monitor API call:
All the parameters are grouped by the Join Rows “Add Monitor Param” step resulting as an input for Add Monitor HTTP Post request . Write to Log step is providing information on transformation execution results where Data field is the ID of created monitor and will be used in the next transformation.
As an input here along with the user data (API and secret keys) we have Custom Monitor ID – result of Create Monitor transformation and Table Input step, which will retrieve the necessary information from database.
HTTP Post step will execute API call for posting monitor data.
4. Creating a job
The only thing left is just creating a simple job to run the transformation for posting metric results.
After test you can use any scheduler to run the created job using Pentaho Kitchen, a standalone command line process that can be used to execute jobs.
And here we can see our custom monitor on Monitis dashboard.
Using these simple transformations as a basis, you can create monitors by just changing input parameters and SQL query in Table Input step for retrieving metric data. Moreover, instead of Table Input step any other transformation Input, Utility, Lookup or Scripting step can be used as a source for monitored data. That will allow you to access relational and NOSQL databases and log files or data input of any format (CSV, JSON, XML, YAML, Excel, plain text …); to base monitor on script execution, Java classes or shell/process output; HTTP, REST and WSDL requests; fetch data from Google analytics account – just feel free to explore rich collection of Spoon transformation steps.

The Industrial Internet revolution is now underway, enabled by connected machines and billions of devices that communicate and collaborate. The massive amounts of Big Data requiring real-time analysis is flooding legacy IT systems and giving way to cloud environments that can handle the unpredictable workloads. Yet many barriers remain until we can fully realize the opportunities and benefits from the convergence of machines and devices with Big Data and the cloud, including interoperability, data security and privacy.

Wearable devices have come of age. The primary applications of wearables so far have been "the Quantified Self" or the tracking of one's fitness and health status. We propose the evolution of wearables into social and emotional communication devices. Our BE(tm) sensor uses light to visualize the skin conductance response. Our sensors are very inexpensive and can be massively distributed to audiences or groups of any size, in order to gauge reactions to performances, video, or any kind of presentation. In her session at @ThingsExpo, Jocelyn Scheirer, CEO & Founder of Bionolux, will discuss ho...

The Internet of Things is a misnomer. That implies that everything is on the Internet, and that simply should not be - especially for things that are blurring the line between medical devices that stimulate like a pacemaker and quantified self-sensors like a pedometer or pulse tracker. The mesh of things that we manage must be segmented into zones of trust for sensing data, transmitting data, receiving command and control administrative changes, and peer-to-peer mesh messaging. In his session at @ThingsExpo, Ryan Bagnulo, Solution Architect / Software Engineer at SOA Software, focused on desi...

Enthusiasm for the Internet of Things has reached an all-time high. In 2013 alone, venture capitalists spent more than $1 billion dollars investing in the IoT space. With "smart" appliances and devices, IoT covers wearable smart devices, cloud services to hardware companies. Nest, a Google company, detects temperatures inside homes and automatically adjusts it by tracking its user's habit. These technologies are quickly developing and with it come challenges such as bridging infrastructure gaps, abiding by privacy concerns and making the concept a reality. These challenges can't be addressed w...

The Domain Name Service (DNS) is one of the most important components in networking infrastructure, enabling users and services to access applications by translating URLs (names) into IP addresses (numbers). Because every icon and URL and all embedded content on a website requires a DNS lookup loading complex sites necessitates hundreds of DNS queries. In addition, as more internet-enabled ‘Things' get connected, people will rely on DNS to name and find their fridges, toasters and toilets. According to a recent IDG Research Services Survey this rate of traffic will only grow. What's driving t...

The Internet of Things is tied together with a thin strand that is known as time. Coincidentally, at the core of nearly all data analytics is a timestamp. When working with time series data there are a few core principles that everyone should consider, especially across datasets where time is the common boundary. In his session at Internet of @ThingsExpo, Jim Scott, Director of Enterprise Strategy & Architecture at MapR Technologies, discussed single-value, geo-spatial, and log time series data. By focusing on enterprise applications and the data center, he will use OpenTSDB as an example t...
