Capture the right data with Kronometrix Data Recording

Capture the right data with Kronometrix Data Recording 2578 1906 KRONOMETRIX

Ready packages to capture the right performance metrics from your systems and applications

Kronometrix Data Recording is an automatic data collection package for IoT, enterprise ICT, web applications, weather and environmental devices. Available as an open source project, for many computer systems, the data recorders can be used to capture the right performance metrics from different data sources. Learn more about Kronometrix data recorders capabilities below.

To simplify how to get started we have created several packages, free of charge, which can be used to capture and transport data for analysis. These packages are offered without support or any other service level agreements.

Check out our free Kronometrix packages

Need support and SLA? Visit our business catalogue to get more packages.

How does it work?

There are different ready made packages for several computer systems or applications. Each package includes all necessarily modules to start and capture data:

  • binaries and data recorders
  • the transport utilities
  • main configurations
  • manual pages and documentation

Select your package, download and install it for your system. After installation, you need to configure it to get your data. Each package includes a short description how to get started.

There are different package, for different industries and applications.

Download you package based on your configuration and industry, from operating systems to industrial IoT installations. Note: we are currently working to improve some of these packages, soon to be available for download.


Check the prerequisites section, of each package to see what are the minimum settings to get started.


Follow the short installation notes how to install your package. For example this is how you will need to install the Raspberry Pi package:

# dpkg -i kdr-stable-raspbian-armv8.deb
The software is found under /opt/kronometrix directory. Current raw data is saved under log directory. The configuration files are found under etc directory. 

See your data

After installation, you have access to the data recording package, including the recorders and the captured raw data from your systems or applications. To visualize, analyze and consolidate all your data you can subscribe to Kronometrix SaaS or directly use the raw data with your own data analytics and visualization applications.

Prevent Silent Data Corruption

Prevent Silent Data Corruption 1584 1224 KRONOMETRIX

Storage capacities have increased substantially, but their error rates remain unchanged and high

Companies are storing and placing their data on different networks, like cloud storage providers or private, on-premises systems and devices totally unaware of the real danger of silent data corruption – “undetected data corruption, also known as silent data corruption, results in the most dangerous errors as there is no indication that the data is incorrect.”

In the past, using older storage technologies, the probability of data corruption was very small because of the volume of data stored. Today, we store massively more data, from audio, video, numerical data, to documents using private or public social networks, without any ideas how safe our data is.

There can be many error sources beyond the disk storage itself, from loose cables, unreliable power supplies to DMA parity errors, external vibrations or other soft errors. Silent data corruption is difficult to detect and report, usually resulting in “cascading failures, in which the system may run for a period of time with undetected initial error causing increasingly more problems until it is ultimately detected”.

Jeff Bonwick, the technical leader of ZFS stated that, “The fast database at Greenplum, which is a database software company specializing in large-scale data warehousing and analytics, faces silent corruption every 15 minutes. As another example, a real-life study performed by NetApp on more than 1.5 million HDDs over 41 months found more than nearly half a million silent data corruptions, out of which more than 30,000 were not detected by the hardware RAID controller. Another study, performed by CERN over six months and involving about 97 petabytes of data, found that about 128 megabytes of data became permanently corrupted.” (Wikipedia)

Kronometrix Data Integrity

Developed with data integrity in mind, Kronometrix is using OpenZFS technology to detect, correct and prevent silent data corruption errors, supporting:

  • long-term data storage: large datastore sizes with zero data loss
  • data integrity: using hierarchical checksum of all data and metadata
  • native data compression: supports archival years of raw data
Intelligent Fabric

Kronometrix connects to a wide variety of data sources: everything from IoT devices, ICT enterprise to weather and environment sensors. In addition to multifaceted data ingress, the distributed data fabric provides high-speed transport for data consolidation, analysis and visualization in real-time.

Built as a ready solution, Kronometrix contains all needed software components, from data collection, to analysis and visualization, on top of core computing capabilities:

  • multi-processor configurations
  • in-memory processing, supporting RAM or flash memory
  • integrated storage and network capabilities
