solely on the show slave status provided by MySQL itself. Pt-heartbeat is a good choice for master-slave replication latency monitoring. This article describes the latency monitoring in the case of master-slave replication and provides corresponding examples. Pt-heartbeat is one of the percona-toolkit. Therefore, you need to install percona-toolkit before use. For details, see percona-toolkit installation

Using pt-heartbeat to monitor the replication latency of MySQL, pt-heartbeatmysql Pt-heartbeat During database master-slave replication, whether the replication status and data delay are normal is a critical indicator. How can we monitor it? Pt-heartbeat is a centralized too
