Overview The task of monitoring complex distributed systems can be a headache, from the configuration and updating point of view and from the performance point of view. The easiest way to avoid problems is to prevent them at the design stage. In this post, we describe how to implement monitoring of a complex distributed system by using Zabbix as the monitoring tool and Apache Ignite as the distributed system. Problems to avoid: Performance: When multiple metrics are processed from multiple nodes, the monitoring system might not be able to cope with the incoming metric stream. Impact on system performance: Metric collection might consume an unacceptable amount of system resources. Redundant complexity: You need a monitoring system that you can trust.The more complex the solution, the higher the probability of failure, especially when changes occur. Guidelines for building a monitoring system:
