Hi, Currently we are using NIFI 2.1, and one workflow is to running SQL from DBCPConnectionPool every 10 minutes to extract data, then do the following logic. Due to the source is the MySQL database in another data center, sometimes the network connection is broken due to network or firewall issues. We would like to have email notification when this kind of thing happens in NIFI. Right now, our first Executor SQL processor, when there is a network connection issue to the source MySQL DB, the only error coming out is in the bulletin or log, which hardly monitored by a human. I wonder if we can design something in the NIFI processor, or it is natively available in NIFI, will trigger Email notification when the DBCP connection pool is broken. Thanks ... View more
