How can I see my IOPS burst credits?

Solution 1:

AWS recently added Burst Balance metric to monitor your balance, the metrics is 0-100% and says how far is your volume from 5.4 million.

The AWS Blog post about it

This is available for EC2 gp2 Volumes as well as RDS gp2 Volumes.

To view it for EC2 EBS Volumes, go to Cloudwatch -> Metrics -> EBS -> BurstBalance.

To view it for RDS Instances, go to Cloudwatch -> Metrics -> RDS -> BurstBalance.

Solution 2:

You can't. As in the link provided by AgDude:

From Nov 5, 2014:

Unfortunately there isn't a Cloudwatch Metric for the current IOPS Credit balance like there is with the CPU credits but I am definitely submitting a feature request through to our EBS/Cloudwatch teams for such a metric.

Up to now, Nov 2, 2015, this feature was not implemented yet.
