Benchmark: Compute Checks
Thrifty Compute Benchmark
Thrifty developers eliminate their unused and under-utilized compute instances. This benchmark focuses on finding resources that have not been restarted recently, are using very large instance sizes, have old snapshots, have low utilization and have unused disks and IP addresses.
Variables
| Variable | Description | Default |
|---|---|---|
| compute_disk_max_size_gb | The maximum size (GB) allowed for disks. | 100 GB |
| compute_disk_avg_read_write_ops_low | The number of average read/write ops required for disks to be considered infrequently used. This value should be lower than compute_disk_avg_read_write_ops_high. | 100 |
| compute_disk_avg_read_write_ops_high | The number of average read/write ops required for disks to be considered frequently used. This value should be higher than compute_disk_avg_read_write_ops_low. | 500 |
| compute_instance_allowed_types | A list of allowed instance types. PostgreSQL wildcards are supported. | ["%-micro", "%-small", "%-medium", "%-2", "%-4", "%-8", "%-16", "%-30", "%-32", "%-1g", "%-2g"] |
| compute_running_instance_age_max_days | The maximum number of days instances are allowed to run. | 90 days |
| compute_instance_avg_cpu_utilization_low | The average CPU utilization required for instances to be considered infrequently used. This value should be lower than compute_instance_avg_cpu_utilization_high. | 20% |
| compute_instance_avg_cpu_utilization_high | The average CPU utilization required for instances to be considered frequently used. This value should be higher than compute_instance_avg_cpu_utilization_low. | 35% |
| compute_snapshot_age_max_days | The maximum number of days snapshots can be retained. | 90 days |
Usage
Install the mod:
mkdir dashboardscd dashboardspowerpipe mod initpowerpipe mod install github.com/turbot/steampipe-mod-gcp-thriftyStart the Powerpipe server:
steampipe service startpowerpipe serverOpen http://localhost:9033 in your browser and select Compute Checks.
Run this benchmark in your terminal:
powerpipe benchmark run gcp_thrifty.benchmark.computeSnapshot and share results via Turbot Pipes:
powerpipe benchmark run gcp_thrifty.benchmark.compute --shareControls
- Unused external IP addresses should be removed
- Disks attached to stopped instances should be reviewed
- Disks should be resized if too large
- Compute disks with low usage should be reviewed
- Unused disks should be removed
- Instances with more then 32 vCPU should be reviewed
- Long running instances should be reviewed
- Compute instances with low CPU utilization should be reviewed
- Old snapshots should be deleted if not required
