Cisco Asr 9K

Hello

We are facing an issue with Cisco ASR 9006 router. We are set up with a 1 minute poller and we are seeing drops and NMS telling us it cannot poll in time. We are also facing an issue were LIBRE will not show graphs for historical info. It will show them for about a week them when we login they are all gone like NMS is showing this as a new device. We do not have any issues with any other devices but this one. All our other devices are cisco type products and never an issue. Can anyone help with this?

See how long its taking to poll your 9006 and if its getting done in time.

Says it is only taking 6 seconds to poll the device.
