How libreNMS distribute poller works?

Hello,

Our DC is not big ~200 devices. We’re considering Distribute poller option to allow us to see what’s going on when problems in the network occur - when setup with single poller cannot reach the network node which is in other continent - all the data is lost.
As I understand in distributed poller setup the poller which would reside in other continent would be able to ‘grap’ the monitoring data and (when the connection would be available again) it would send the information from other continent ‘local’ poller to the 'main server. Do i’m correctly understand distributed poller principle ? Do the data saved in one (distant) poller could be resented when connection between two Pollers is up again ?

Thank you

Distribute poller was meant to help even out the load by separating the services. It was not meant to do remote polling. You can do it but if there is not enough bandwidth and a lot of latency you could run into issues.

You would still lose the data because if it is down, your distributed poller would not be able to reach your rrd or mysql server.

What you want maybe is multiple LibreNMS instances.
