CPU utilisation data in bulk from API

How can I get server device CPU or Memory utilisation data from the API in bulk. I can get this from individual servers by specifying the device_id (i.e. /api/device/<device_id>/performance_data/838/...

    Hi Martin,

    This is the correct way to get the data, the RestAPI does not have a faster method. What I've seen before is that this use case to have the devices that you want to get the data from in a Device Group. There is a Device Group API (/api/device_group/guid) that provides the Device ID's, it lists out the first part of the URI:

    So your code can get that list and loop through them to get the /performance_data/838/data?duration=24h part.

Hi Eric,

Thanks for confirming. I'm looping through the devices to get the stats for each device now. I also have to specify different performance data id's for the same metric depending on the OS. i.e. Linux CPU utilisation =5548 and Windows CPU utilisation =4445.

I was hoping I could do something similar to when getting disk utilisation metrics: I.e. /api/data_performance_raw/device/filesystem?duration=24h&data_fields=d_used_percent.

Either way, It's good to know that I'm doing it the correct way.

Thanks!

Yes, I agree with you there. Unfortunately CPU is a "per vendor" type of metric whereas file system utilization is normalized across all vendor sources. That may change eventually, but for now you have it correct.
