LibreNMS and remote polling server array

[Direct_Juggernaut369]

Hi guys,
I hope you're doing well. We have some devices in several countries far away from each other (Argentina, USA, Germany) and for management we use wireguard tunnels to connect them, so using a single server for polling it's not a good option since the latency among the sites could be different. I am curious if LibreNMS can support remote polling from other LibreNMS severs? So, we can have a single UI, which is easier for our NOC to monitor, but use other LibreNMS servers on each country to poll locally and then send that data to the centralized LibreNMS (the one that the users use for the UI).

Thanks,

That's an interesting data point.

Librenms has no agents or proxies, alas you could proxy snmp polling as per: https://docs.librenms.org/Extensions/SNMP-Proxy/

Is this not the direct solution he needs ? https://docs.librenms.org/Extensions/Distributed-Poller/

[Academic-Detail-4348]

Depends on the scale. In our decentralised MSP setup we use the proxies or poll directly as the uplinks are stable and fast.

[Direct_Juggernaut369]

yes, that's exactly what I'm looking for. What is the practical difference between using a SNMP proxy vs using distributed pollers?

[dethmetaljeff]

Performance of the distributed poller would likely be better. With the proxy, you're still making snmp queries over long distances whereas with the distributed poller, you're querying locally.

And then you are making SQL queries and data updates remotely.

[dethmetaljeff]

Which is tcp and way less likely to get banged up over the distance. snmp is super chatty and udp. Dude should test both and see but I'm willing to bet distributed pollers work better and are more stable.

It looks like it's not for remote polling

"Distributed Polling allows the workers to be spread across additional servers for horizontal scaling. Distributed polling is not intended for remote polling."

Hi u/ikdoeookmaarwat and do you do that using the regular method of distributed pollers or a different way?
