i have a librenms server under ubuntu, recent everything works perfectly. this server does everything by itself (poll-bdd-webui)
I would like to create new poller to increase redundancy.
but according to the doc, this implies configuring rrdcached, memcached, redis, rrdtool, NFS and rrdtune?
do you have a tutorial guide to configure all this or explain the main thing? because the docs are light on scaling librenms.
thank you very much.
I’ve been where you are, and I get it, it’s not easy when you’re starting out. My guess is that the Example Setups section is confusing or overwhelming you because it shows setups far more complex than your own, but pay attention to the Architecture section immediately aftewards:
How you set the distribution up is entirely up to you. You can choose to host the majority of the required services on a single virtual machine or server and then a poller to actually query the devices being monitored, all the way through to having a dedicated server for each of the individual roles.
Right now most of the services you need are already present on your one server. You probably just need to add the ones listed under Requirements for Distributed Polling.
Setting up the new poller itself isn’t too bad, see this section: Pollers
The configuration is mostly pointing different tools at whichever server they’re installed on, and creating a single poller group to start with.
Good luck!
