NiFi Monitoring

Apache NiFi is an easy to use, powerful, and reliable system to process and distribute data. It supports powerful and scalable directed graphs of data routing, transformation, and system mediation logic. Moein monitoring system has the capability of monitoring NiFi. In this regard, it provides java virtual machine (JVM) performance indicators such as heap memory, garbage collectors, and threads metrics; as well as flow file, Content and provenance repositories, processors health metrics, and nodes status in cluster modes. The following is a list of performance indicators for Apache NiFi:
