disk_used_percent does not work with device name xvda1 in Amazon Linux AMI

[vumdao]

From the CwAgent namespace, the collected metrics do not contain information xvda1 device name but the mapping

[root@ip-10-0-196-70 bin]# ls -la /dev/xvda1
lrwxrwxrwx 1 root root 9 Apr 21 15:25 /dev/xvda1 -> nvme0n1p1

[root@ip-10-0-196-70 bin]# cat /etc/os-release

Hello, thanks for reporting this, it appears the default device name has changed. I have updated the default_alarms dictionary to reflect the new default device nvme0n1p1:
