# Monitor a VM

The **Monitoring** tab of a TIR Virtual Machine shows how much CPU, memory, disk, network, and
storage the VM is using, and on a GPU plan, how hard the GPUs are working. TIR collects the figures
for you, so there is nothing to install. Use the tab to catch a full disk or a busy processor before
it slows your work.

## Before you begin

You need a VM in the **Running** state, because the figures come from the running VM.
See [Stop, start, and restart a VM](/tir/tir-vm/how-to/stop-start-and-restart-a-vm/).

## Open the Monitoring tab

In **Manage VMs**, select the VM's name, then select the **Monitoring** tab.

**Disk Usage** at the top says how full the disk is, measured when you open the tab. To look
further back than the last five minutes, choose **1h**, **1d**, **7d**, or **30d**, for example **7d** to see whether a slowdown repeats at the same time
each day. The refresh button loads the latest figures.

## Read the figures

| Figure                                                               | What it tells you                                           |
| -------------------------------------------------------------------- | ----------------------------------------------------------- |
| **CPU Utilization**, **RAM Utilization**                             | Whether the plan has enough vCPUs and memory                |
| **Uptime**                                                           | How long the VM has run since it last booted                |
| **Network Bandwidth**, **Network Packet Rate**                       | How much traffic the VM sends and receives                  |
| **Storage IOPS**, **Storage Throughput**                             | How busy the disk is                                        |
| **GPU Utilization**, **GPU Memory Used**                             | On a GPU plan, how hard the GPUs work and how full they are |
| **GPU Temperature**, **GPU Power**                                   | On a GPU plan, the GPUs' heat and power draw                |
| **GPU Memory Bandwidth**, **Tensor Throughput**, **PCIe Throughput** | On a GPU plan, how fast data moves through the GPUs         |

**Max GPU Temperature** is included when the GPU reports a value.

When the disk is filling up, [resize the
disk](/tir/tir-vm/how-to/resize-the-disk-of-a-vm/). When CPU or memory stays near the top, [move the
VM to a larger plan](/tir/tir-vm/how-to/change-the-plan-of-a-vm/).

## Read a VM's logs

A VM keeps its logs inside its operating system, and you read them there. Sign in over SSH, as in
[Connect to a VM over SSH](/tir/tir-vm/how-to/connect-to-a-vm-over-ssh/), and use the tools of the
image, such as `journalctl`.

To get a warning when a figure crosses a limit, see [Set up alerts for a
VM](/tir/tir-vm/how-to/set-up-alerts-for-a-vm/). For help with a message on the tab, see
[Troubleshooting TIR Virtual
Machines](/tir/tir-vm/troubleshooting/tir-vm/#metrics-are-not-available-when-the-vm-is-offline).
