Checking Current Usage

​
Via Dashboard

  1. Go to moru.io/dashboard
  2. View Usage section
  3. See current sandboxes, templates, and resource usage

​
Via SDK

# Check sandbox metrics
metrics = sandbox.get_metrics()
for m in metrics:
    print(f"CPU: {m.cpu_used_pct:.1f}%")
    print(f"Memory: {m.mem_used / 1024 / 1024:.0f} MB / {m.mem_total / 1024 / 1024:.0f} MB")
    print(f"Disk: {m.disk_used / 1024 / 1024:.0f} MB / {m.disk_total / 1024 / 1024:.0f} MB")

​
Via CLI

# Check sandbox metrics
moru sandbox metrics sbx_abc123

# List all sandboxes
moru sandbox list

​
Handling Quota Errors

​
Concurrent Sandbox Limit

When you hit the concurrent sandbox limit: 
from moru.exceptions import SandboxException

try:
    sandbox = Sandbox.create()
except SandboxException as e:
    if "quota" in str(e).lower():
        # Kill old sandboxes
        for info in Sandbox.list():
            if should_cleanup(info):
                Sandbox.kill(info.sandbox_id)
        # Retry
        sandbox = Sandbox.create()

​
Disk Space Limit

from moru.exceptions import NotEnoughSpaceException

try:
    sandbox.files.write("/large_file", data)
except NotEnoughSpaceException:
    # Clean up old files
    sandbox.commands.run("rm -rf /tmp/*")
    sandbox.commands.run("rm -rf ~/.cache/*")
    # Retry
    sandbox.files.write("/large_file", data)

​
Need More Resources?

If you need higher limits (more concurrent sandboxes, longer duration, more vCPUs/RAM), contact us at hi@moru.io.

​
Resource Optimization Tips

​
Reuse Sandboxes

# Keep sandbox alive for multiple tasks
sandbox = Sandbox.create(timeout=3600)  # 1 hour

for task in tasks:
    sandbox.commands.run(task)
    sandbox.set_timeout(3600)  # Reset timeout

sandbox.kill()

​
Clean Up Promptly

# Use context manager for automatic cleanup
with Sandbox.create() as sandbox:
    result = sandbox.commands.run("task")
# Sandbox automatically killed

​
Use Templates

Pre-install dependencies in templates to reduce setup time and disk usage per sandbox.
