Thanks – clearing out some modules now..
With a stock Cisco 3850 switch – the CPU goes insane… that’s really a buggy box though – the IOS XE has been a bust… the old 3750X’s were so much more stable and reliable…
We are getting high cpu polling them

Joseph,
Thanks for the feedback! You can also accomplish something similar by disabling the poller modules that cause high CPU on a device.
1) Using the web-interface, click on the device with high CPU. 2) Click on the "Gear" icon on the right side to edit device settings. 3) Click on the "Modules" tab 4) Now you can disable the modules that you don't want Observium to attempt on this device
Note that you can also disable poller modules globally by editing the "config.php" file. Here are some of the options you can set:

We had some cisco switches dropping packets with 99% cpu being polled by Observium.
We had to create a view which hides some arp and routing table objects to bring the CPU back down to normal levels
