Here’s how to get the EFS Burst Credits from CloudWatch via AWS CLI.
aws cloudwatch get-metric-statistics \ --namespace "AWS/EFS" \ --metric-name BurstCreditBalance \ --dimensions "Name=FileSystemId,Value=fs-xxxxxxx" \ --start-time 2019-12-31T00:00:00Z \ --end-time 2019-12-31T01:00:00Z \ --statistics Average \ --period 3600 \ --profile default |

Notice the start time, end time, period and statistics. Here’s the CLI doc.
To automatically mount a EFS volume after each reboot, you’ll need to add the following format to /etc/fstab.
You can use the DNS name given by AWS.
fs-12345678:/ /mnt/efs efs defaults,_netdev 0 0 |
fs-12345678:/ /mnt/efs efs defaults,_netdev 0 0
Or the IP address.
10.0.0.22:/ /mnt/efs efs defaults,_netdev 0 0 |
10.0.0.22:/ /mnt/efs efs defaults,_netdev 0 0
Mount all with fake and verbose.
mount -fav |
mount -fav
Here’s how to display mount targets of an EFS system via AWS CLI.
