Sandbox metrics

The sandbox metrics allows you to get information about the sandbox’s CPU, memory and disk usage.

Getting sandbox metrics

Getting the metrics of a sandbox returns an array of timestamped metrics containing CPU, memory and disk usage information. The metrics are collected every 5 seconds.

Getting sandbox metrics using the SDKs

JavaScript & TypeScript

import { Sandbox } from 'e2b'

const sbx = await Sandbox.create()
console.log('Sandbox created', sbx.sandboxId)

// Wait for a few seconds to collect some metrics
await new Promise((resolve) => setTimeout(resolve, 10_000))

const metrics = await sbx.getMetrics()

// You can also get the metrics by sandbox ID:
// const metrics = await Sandbox.getMetrics(sbx.sandboxId)

console.log('Sandbox metrics:', metrics)

// Sandbox metrics:
// [
//   {
//     timestamp: 2025-07-28T08:04:05.000Z,
//     cpuUsedPct: 20.33,
//     cpuCount: 2,
//     memUsed: 32681984,  // in bytes
//     memTotal: 507592704,  // in bytes
//     diskUsed: 1514856448,  // in bytes
//     diskTotal: 2573185024  // in bytes
//   },
//   {
//     timestamp: 2025-07-28T08:04:10.000Z,
//     cpuUsedPct: 0.2,
//     cpuCount: 2,
//     memUsed: 33316864,  // in bytes
//     memTotal: 507592704, // in bytes
//     diskUsed: 1514856448,  // in bytes
//     diskTotal: 2573185024  // in bytes
//   }
// ]

Getting sandbox metrics using the CLI

Terminal

e2b sandbox metrics <sandbox_id> 

# Metrics for sandbox <sandbox_id>
# 
# [2025-07-25 14:05:55Z]  CPU:  8.27% /  2 Cores | Memory:    31 / 484   MiB | Disk:  1445 / 2453  MiB
# [2025-07-25 14:06:00Z]  CPU:   0.5% /  2 Cores | Memory:    32 / 484   MiB | Disk:  1445 / 2453  MiB
# [2025-07-25 14:06:05Z]  CPU:   0.1% /  2 Cores | Memory:    32 / 484   MiB | Disk:  1445 / 2453  MiB
# [2025-07-25 14:06:10Z]  CPU:   0.3% /  2 Cores | Memory:    32 / 484   MiB | Disk:  1445 / 2453  MiB

It may take a second or more to get the first metrics after the sandbox is created. Until the first metrics are collected from the sandbox, you will get an empty array.
