Easy Monitoring of DFS Replication in Zabbix

Introduction With a sufficiently large and distributed infrastructure using DFS as a single point of access to data and DFSR for data replication between data centers and branch servers, the question of monitoring the status of this replication arises. It just so happened that almost immediately after starting to use DFSR, we began implementing Zabbix with the aim of replacing the existing zoo of various tools and streamlining monitoring […]

Integrating ELK and Exchange. Part 1
