This testimonial relates to CentOS, Linux, Merlin, Nagios, PNP4Nagios, and Thruk:

"To both the Adam's thank you for your hard work, flexibility and attention to detail whilst building our Nagios distributed monitoring system. We are now able to monitor our entire IT estate with one application that surpasses the abilities of the previous eight software applications that were used. We would have no hesitation in recommending Transitiv for consultancy, development and support of Nagios Network Monitoring."

Selection Services were monitoring around 2,000 devices using a variety of monitoring platforms. The intention of this project was to replace those with Nagios within a deadline of 6 weeks. A test Nagios deployment was in place but was struggling with only 500 devices, so this project included the use of a number of distributed Nagios systems which communicate using Merlin.

Their work has been excellent, delivered on time and cost effective. As an organisation, they are extremely customer focussed and have been able to provide solutions to some IT problems that other companies have said were not possible. We would have no hesitation in recommending Transitiv."

I just wanted to put on my record my thanks to you and your team for the flexibility and responsiveness shown yesterday in joining a call so quickly. It is greatly appreciated.

Many thanks again for your support.
Kind regards

This testimonial relates to CentOS:

"The training that Transitiv provided was exactly what we were looking for. The training filled in a number of gaps for me, and has given me the confidence to do even bigger and greater things with Centos. Adam took the time to explain any features that we struggled to get to grips with, and I would not hesitate in recommending Transitiv Technologies to anybody thinking about a Centos training course." Regards Lee

"The 3 days spent with Chris offered us much insight. Chris demonstrated extensive knowledge and he was able to clearly articulate his findings and provide recommendations. I would like to thank Transitiv for their quick attention to our needs and I am sure we will make use of your services in the near future."

This testimonial relates to Linux and Ubuntu:

Again, thank you for your prompt assistance , it was a pleasurable experience working with Adam and I am sure this will not be the last!

― Marius Vanaswegen, Operations Director, The Test Factory Ltd

This testimonial relates to Postfix and Red Hat Enterprise Linux:

"My experience of Transitiv has been that they are competent, reliable, communicative, and cost-effective.
Competent because they obviously know their stuff, but also have the breadth of knowledge to pin down tricky problems where the cause may actually be outside of the application having the problem.
Reliable because they implement robust solutions which just look after themselves.
Communicative because they are responsive to emails, and run a generally professional operation.
Cost-effective because they achieve a lot in the time they are working, and manage to implement and maintain reliable open-source solutions which are way cheaper (and better) than the alternatives.
I run a large dating site which sends out a significant volume of transactional email every day, and Transitiv's expertise allows me to manage this in house, on my own mailserver. If I outsourced it, I would be paying at least ten times as much."

This testimonial relates to Apache Tomcat, Linux, and MySQL:

"Thank you for your prompt attention and the satisfactory conclusion to our MySQL issues."

― Ian.W, Group Infrastructure Manager, open gi

This testimonial relates to Debian, Merlin, Nagios, Ninja, and PNP4Nagios:

"As an ICT consultancy for public and private sector with customer sites spread across the UK, it's important for us to be alerted immediately when a problem occurs at a customer location. We contacted Transitiv to develop a monitoring system with remote monitoring stations on customer sites and a central management console so that we can see the status of all internal and customer ICT infrastructure from a single interface.

This system was developed by Transitiv and is now in active use by employees and customers alike. As a result we are alerted to the root cause without spending time diagnosing the issue, meaning we are able to respond immediately and resolve issues well within our agreed SLA's. The resource graphing allows us to see potential issues developing before they become problems, see which systems are under strain, plan for upgrades and generally become pro-active about support issues, fixing them before serious problems occur. As a consequence our customers have noticed that the number of support issues has reduced. We become aware of issues and fix them before our clients do and the reporting system allows us to present hard data to our customers with regards to system availability on request or as a scheduled report.

Throughout this project we have been particularly impressed with the level of analysis of our systems to ensure the best results from the monitoring system they developed and also with the technical recommendations which have been offered as a bi-product of this process. We are therefore more than happy to recommend Transitiv Technologies."

― Stephen Welch, Managing Director, Invictus Technology Ltd.

This testimonial relates to CentOS, KVM, and Xen:

"Thank you Adam. The Xen and KVM training you provided was both informative and fun. We now feel in a comfortable position to choose an Open Source virtualisation platform that will meet our requirements now and in the future. Also the tips, tricks, pitfalls and things to watch out for that can occur in a high profile environment was really useful. Thank you for taking the trouble to really understand our needs."
