Librenms - High CPU and memory usage issues

Hello Team,

I have configured Librenms with below server sizings.

  1. server 1: Main server- plus Web Gui(4CPU and 8GB RAM RHEL8.9)
  2. server 2: MariaDB (8CPU and 16GB RAM RHEL8.9)
  3. server 3 : RRD storage(8 CPU, 16GB RAM and Disk 120GB RHEL 8.9)
  4. server 4: Distributed poller (8 CPU and 16GB RAM RHEL 8.9) used Redis server for distributed poller configuration.

Onboarded 40 routers and 280 LAN switches.

We noticed high CPU load and Memory usage on Distributed poller(server4). Please help to suggest the steps to reduce CPU and memory usage issue. Increase performance for the Librenms server.

Kindly do the needful

Thank you
Best Regards
Prakash
