Hello, I've been looking into using collectd combined with zeromq for transport. This seems like a fairly good way to scale out monitoring infrastructure as each node being monitored can send out requests over zeromq to one or more locations with little overhead. I was wondering if anyone has any experience doing this, or can provide some guidance on what zeromq architecture would scale best.
With my limited zeromq knowledge, I'm thinking that each node being monitored would publish to one or more "collector" nodes, which could then reroute the information down to a single point where graphing and alerting thresholds could be handled. The "collector" nodes would likely be in each datacenter and running collectd to write to RRD files. These instances of collectd, could also be publishing or pushing data down to a single aggregation system. I guess my real question here, is what zeromq pattern would make most sense for a distributed collectd monitoring system. Any insight or suggestions are greatly appreciated. Thanks, Allan
