MMBatch Management Server

The MMBatch Management Server functions as both an API server and a central point for metrics collection and global checkpoint configuration. Metrics from worker nodes are displayed in an interactive single-page application (SPA).

Reporting

The MMBatch Management Server provides reporting for visibility of the spot reclaim protections as well as estimated time savings.

An example below - Dashboard

The definitions of the metrics are -

  • Total Jobs - Total number of AWS Batch jobs submitted with MMBatch installed and enabled

  • Spot Protections - Total number of spot reclaim protection MMBatch provided

  • Total Job CPU Hours - Total number of CPU hours requested by all AWS Batch jobs submitted with MMBatch installed and enabled. It is based on CPU requested, not the actual CPU usage.

The CPU hours of an individual job is computed as follows:

CPU time (CPU-hours) = Job requested CPUs × Job runtime

The runtime of an individual job is computed as follows:

Job runtime = Job complete − Job start

  • Total EC2 Instance Cost: Estimated total cost for all jobs.

  • EC2 Spot Savings - Instance Cost Saved: Estimated cost savings when restoring a job from a preempted spot instance, assuming each spot instance runs only one job.

  • EC2 Spot Savings - Job CPU Hours Saved: Estimated Job CPU Hours savings when restoring a job from a preempted spot instance, assuming each spot instance runs only one job.

  • EC2 On-demand Savings - Instance Cost Saved: Estimated savings when replacing on-demand instances with spot instances.

User can also see the AWS queues from MMBatch Management Server, including the number of jobs submitted.
