Our colleague Daniel, as one of the 13 IT specialists in the world so far, has received the Zabbix Certified Expert 4.0 certificate. This happened in the Polish city of Gdansk, where he successfully passed the certification exam. This included a wide range of demanding tasks in the field of monitoring IT infrastructures and case studies in the form of troubleshooting, which had to be solved within a specified time. Imagine that Daniel is an emergency doctor to whom a critically ill patient is brought. He shall make a quick medical history, diagnose, determine treatment, and finally stabilize and cure the patient. It is somewhat similar with IT monitoring. How to set up the system so that any critical information about the state of the environment is missed out or not taken into consideration? Just few people can pass this test and that is why we are really proud about Daniel's achievement.
