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

Kronometrix CloudView Managed Service

Kronometrix CloudView Managed Service 17280 11520 Kronometrix

Find out if your applications and services are properly configured and optimised for your business and customers

A lot of organizations are spending considerable time and energy, to detect and correct improper service configurations, which have a direct impact to the main operation and functionality, as poor performance or outages. These activities, many times, continue as a fire-fighting exercise, without a strategy and direction, exhausting everybody and getting very expensive.

Kronometrix CloudView brings all necessarily tools and utilities to build and define a direction, to simplify all these and get the job done.

For example, when we deployed Kronometrix CloudView for Nexetic, one of our customers, we have received several alarms from various parts of the applications and systems. Kronometrix uses a special algorithm, based on sampling the prescribed frequency and duration of trigger events, to eliminate the typical flood of unnecessarily repetitive alarms. Having a relatively high number of alarms was an indication for us, that certain things were not properly configured or correctly set to run.

Using the alarm list, we were able to navigate and detect the most important parts of the system and services which required immediate attention. Working with the devops team, we were able to take one issue at the time, perform changes to immediately improve the performance and ultimately the availability of the service.

How it works

To help you run your business smoothly in the cloud, we continuously monitor your applications, services, and operating system instances: no matter whether it be public, private or a hybrid cloud nor which vendor you have selected to provide the infrastructure. Moreover, when things go wrong or become inefficient, we let you know what the problem is and how best to fix it.Kronometrix Cloudview is an enterprise service, built on top of Kronometrix SaaS designed to track your cloud infrastructure usage and keep you aware of changes before they happen.

Avoid Certificate Expiration

Avoid Certificate Expiration 960 641 Kronometrix

Find out how Kronometrix can keep track of your security certificate settings and prevent a data breach

Are your services and applications properly configured and secure for your business and customers? When more and more companies and services are starting to automate the renewal process of the security certificates, using providers like, Let’s Encrypt it is more important than ever to ensure your X.509 security certificates are properly configured and installed.

The attackers pulled data out of the network in encrypted form undetected for months because Equifax had crucially failed to renew an encryption certificate on one of their internal security tools.

March 2017. Equifax data breach

“The attackers were able to gain access to multiple Equifax databases containing information on hundreds of millions of people. But how were they able to remove all that data without being noticed?

Like many cyberthieves, Equifax’s attackers encrypted the data they were moving in order to make it harder for admins to spot; like many large enterprises, Equifax had tools that decrypted, analyzed, and then re-encrypted internal network traffic, specifically to sniff out data exfiltration events like this. But in order to re-encrypt that traffic, these tools need a public-key certificate, which is purchased from third parties and must be annually renewed. Equifax had failed to renew one of their certificates nearly 10 months previously — which meant that encrypted traffic wasn’t being inspected.

The expired certificate wasn’t discovered and renewed until July 29, 2019, at which point Equifax administrators almost immediately began noticing all that previously obfuscated suspicious activity; this was when Equifax first knew about the breach.”  http://bit.ly/equifax-securitybreach

A simple example, how such large organization, like Equifax failed to notice  and maintain application basic security configuration – X.509 certificate expiration, something no one was really paying attention to, which allowed the attackers to penetrate even deeper in the infrastructure, without being noticed for months.

How Kronometrix helps

To help you run your business securely in the cloud or private network, Kronometrix continuously monitors the validity of X.509 security certificates of all your applications or services. When one of your security certificate approaches the expiration date, an alarm will be issued to notify your operation personnel.

Kronometrix checks several metrics for each X.509 security certificate to ensure the certificate is valid, that it is properly installed and that it is operational. Expired, missing or unavailable data from a X.509 security certificate will automatically raise an alarm. All information is displayed visually using a Kronometrix application, called CertCheck, which offers access to all your certificates, including the following information:

  • total number of X.509 certificates
  • certificates already expired
  • certificates which will expire in the next 30 days
  • valid number of certificates

In this way, Kronometrix will automatically keep track of your X.509 security certificates, across all your services and applications without supplementary manual labour work, additional software licenses or 3rd parties applications.

How it works

From data recording to visualization and reporting, Kronometrix provides a complete unified solution to ensure all your enterprise security certificates are never out of date. A data recorder, called certrec, which is part of Kronometrix Data Recording will collect from all your services and applications the X.509 certificate data. A transport utility will convert raw data, into Kronometrix data messages and will deliver the results to a backend system for analysis and alarms.

This is a standard feature of Kronometrix, available as a service or for on-premises installations. If you have any questions or need more information about this, please visit Kronometrix Distributed Data Fabric, or contact us.

  • present weather conditions
  • city air pollution
  • building indoor air quality

Ecological Revitalization

Pikanore Ltd. has selected Kronometrix Analytics to provide continuous weather and environment measurements from their workplaces.

Revitalizing properties for ecological purposes refers to the process of cleaning-up and returning contaminated land to a state that supports functioning and sustainable habitat. This is a very important mission to protect human health and the environment. 

Different technical activities, like excavation and earthmoving equipment can significantly disrupt existing habitat during cleanup. Measuring the impact of these activities is essential to ensure normal functioning of the clean-up process and alignment with current rules and environment regulations.

How does it help?

Kronometrix collects data from different weather equipments, reporting current weather conditions around different workplaces: wind speed and direction, air temperature, air pressure, humidity, precipitation accumulation and offers access to the original raw data to build different other weather reports, if required. Having access to original historical raw data, offers maximum flexibility to build and analyze any weather conditions using our own in house applications. Kronometrix helps us to consolidate and integrate different data from weather to air quality in a simple, and efficient way.

Such way, Kronometrix is helping Pikanore to ensure all their workplaces comply with the current environmental regulations and their clean-up operations do not harm the environment.

  • and all configurations

A MicroSD card, includes all software modules and packages, available from www.kronometrix.com. Running on top of Raspberry PI SBC, Kronometrix IoT Gateway (K1 Internal Technical Name) is very simple to use and run or embed to other different projects.

How does it work ?

You can connect Kronometrix IoT Gateway to your network and get access to its main features using a screen and a keyboard, or remotely using SSH2 protocol or a serial connection. You can select what data recorders you want to run, using the main configuration file kronometrix.json, from ICT enterprise to IoT:

  • measuring the performance and availability of several web sites or applications using HTTP/HTTPS protocol
  • fetching data from different Internet & enterprise services, like: IMAP, POP3, LDAP, SMTP, HTTP, MariaDB, Memcached, Redis, Isilion storage or any TCP based service
  • checking the performance and availability of different UDP services, like NTP, DHCP
  • measure indoor or city air pollution using different industrial MODBUS sensors and devices
  • fetch data from various weather equipment using USB or direct SERIAL connections

A future version will offer a simple web management interface to simplify even further the management and usage of Kronometrix IoT gateway.

Recorders

A central part of our IoT gateway are the data recorders. Recorders are not software agent(s), nor they should be confused with them. They are independent, light software probes designed as CLI to test and fetch certain minimal data points from different parts of a system(s), more or less same way how a sensor operates. The recorders share a common runtime engine, powered by Perl5. The recorders do not know nor have any knowledge of any transport layer. The output of each data recorder is a simple CSV based raw data file, stored locally on the gateway for a number of days. For more information you can read here. By default the sampling rate of a data recorder is 60 seconds, which is configurable.

Transport

The original raw data can be transported for further analysis and visualisation to Kronometrix SaaS, or any other Kronometrix installation or even to 3rd parties analytics or business intelligence platforms. The transport utility keeps tracks of any raw data changes and periodically sends the update to one or many backend destinations, using HTTP or HTTPS protocol. The transport utility uses a JSON based configuration file.

The data recorders and transport utilities are built together as a binary package for several operating systems. For systems or installations which do not require a complete IoT gateway there is always a possibility to manually install the data recording package.

Raw data

All recorded observations are stored as raw data. Raw data is produced by a recorder, which fetches data from a system, device or sensor, data which has not been modified, altered or changed in any way. All collected metrics are variable measured sequentially in time, called time series. All these observations collected over fixed sampling intervals create a historical time series. To easy the access to all this set of data we store the observations on commodity disk drives, compressed, in text format, like CSV format.

Time series let us understand what has happened in past and look in the future, using various statistical models.

What’s New ?

There are new features and improvements available on the latest version of Kronometrix IoT Gateway 1.4. Some of the very important features:

Tuning Java Virtual Machine

Tuning Java Virtual Machine 3000 2250 Kronometrix

Usually Java applications are deployed with default settings not suitable for production usage

JVMTune is a specialised performance analysis and observability service for Java based applications, focused to the Java Virtual Machine configuration: the heap memory usage, the garbage collection statistics and the overall system memory footprint.

In general Java based applications are deployed with default or ad-hoc settings without proper testing and not suitable for production usage. It is important to analyse all these aspects to make sure your applications is good throughput and response time.

The heap memory configuration will be checked, including: Young, Old and Permanent generation sizes. Each generation will be tuned based on the various synthetic load tests and we will ensure that the heap footprint is properly set and the application works properly without errors. A garbage collector will be selected in order to minimise the number of collection activities and ensure the application has a good throughput.


Improper memory settings can cause poor performance and affect overall availability of your application.

We will look for the following goals:

  • throughput – the total time not spent in garbage collection
  • pause time – the time during the application is paused when the collection takes place
  • frequency – how often the collection occurs

Every time your application is changing, you should consider running JVMTune service, in order to ensure the throughput and response time are correct. System developers, devops and architects are directly interested to know how the Java based applications are functioning and performing over time. Avoid outages, maximise application performance with JVMTune.

Turbo charge your Java applications. Get in touch with us for more information about JVMTune and how can you get started.
