  • Respond to issues at the first sign of a problem.
  • Automatically fix problems when they are detected.
  • Coordinate technical team responses.
  • Ensure your organization’s SLAs are being met.
  • Monitor your entire infrastructure and business processes.

  • review rating 4  It was good session, I left my training room with basic knowledge on all the tools. Tutors have great knowledge and experience on the tools. But three days is not enough time.

  • review rating 5  Excellent Training program. Training courses and trainers are very good. Trainer will explain you as many time you ask the question. Best thing is hands on based training. You learn by doing. Looking for more courses from here.

  • review rating 4  Both trainers (Ravi and Naresh) were excellent in their approach. Session was less of a theory and more of a practical. And even the theory part was quite interesting. A bit issue with the volume of information which I had received in just a span of 2-3 days - it seemed a bit over-loaded. But overall, it has given me a great platform to take it forward from here!
