  • 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  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!

  • 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.
