# logs Command - Medusa Cloud CLI Reference
Fetch runtime logs for a Cloud environment's backend or storefront.
### With Flags
```bash
mcloud logs --organization org_123 --project proj_123 --environment env_123
```
### Using mcloud use
```bash
# Run once: mcloud use --organization org_123 --project proj_123 --environment env_123
mcloud logs
```
By default, the command retrieves the last 500 log lines from the past 15
minutes and prints them to the terminal. You can narrow the output with
filters for time range, deployment, source, metadata, and search terms, or
stream new log lines continuously with `--follow`.
## Options

|\`--limit \\`|Maximum number of log lines to retrieve. Only used in non-follow mode.

## Process Logs in an Agentic Workflow
{/* TODO revisit once we have skills */}
Use `--json` to get machine-readable output that you can pass to `jq` or
other tools for filtering and analysis:
### With Flags
```bash
mcloud logs \
--project proj_123 \
--environment production \
--search "500" \
--json | jq '.[] | .message'
```
### Using mcloud use
```bash
# Run once: mcloud use --project proj_123 --environment production
mcloud logs --search "500" --json | jq '.[] | .message'
```
Set the active context once with [`mcloud use`](https://docs.medusajs.com/cli/commands/use) to avoid repeating project and environment flags across multiple commands:
```bash
mcloud use --project proj_123 --environment production
mcloud logs --search error --limit 500 --json
mcloud logs --follow
```
***
## Stream Live Logs
Use `--follow` to tail an environment's logs continuously. This is useful
when monitoring a deployment in progress or watching for errors in real time:
### With Flags
```bash
mcloud logs \
--organization org_123 \
--project proj_123 \
--environment env_123 \
--follow
```
### Using mcloud use
```bash
# Run once: mcloud use --organization org_123 --project proj_123 --environment env_123
mcloud logs --follow
```
The command polls for new lines until you stop it with `Ctrl+C`.
`--follow` is incompatible with `--json`. To process logs programmatically
in a script, use a bounded time-window fetch instead.
***
## Search for Errors
If you're looking for errors in the logs, use `--search` to filter log lines by a substring. This works the same
as the search bar in the Cloud dashboard logs view:
### With Flags
```bash
mcloud logs \
--organization org_123 \
--project proj_123 \
--environment env_123 \
--search error \
--limit 1000
```
### Using mcloud use
```bash
# Run once: mcloud use --organization org_123 --project proj_123 --environment env_123
mcloud logs --search error --limit 1000
```
Alternatively, if you're looking for HTTP calls that resulted in 500 or other error status codes, use the `--metadata` filter to find log lines with `status_code=500`:
### With Flags
```bash
mcloud logs \
--organization org_123 \
--project proj_123 \
--environment env_123 \
--metadata status=500 \
--limit 1000
```
### Using mcloud use
```bash
# Run once: mcloud use --organization org_123 --project proj_123 --environment env_123
mcloud logs --metadata status=500 --limit 1000
```
***
## Fetch Logs for a Specific Deployment
When a deployment fails, query the logs for that deployment directly using
its ID. Find the build or deployment ID from [`mcloud deployments list`](https://docs.medusajs.com/cli/commands/deployments#deployments-list) or the Cloud
dashboard. Pass a build ID and the CLI resolves it to that build's latest deployment automatically.
To fetch the build logs for a deployment instead of its runtime logs, use [`mcloud deployments build-logs`](https://docs.medusajs.com/cli/commands/deployments#deployments-build-logs).
### With Flags
```bash
mcloud logs \
--organization org_123 \
--project proj_123 \
--environment env_123 \
--deployment bld_01ABC123
```
### Using mcloud use
```bash
# Run once: mcloud use --organization org_123 --project proj_123 --environment env_123
mcloud logs --deployment bld_01ABC123
```
***
## Specify Logs Time Range
You can use the `--from` and `--to` flags to specify a time range for fetching logs instead of the default "last 15 minutes".
Both flags accept ISO 8601 timestamps. When either or both are passed, the command retrieves all log lines within the time range, up to the maximum specified by `--limit` (default 500).
### Example: Fetch Logs within a Time Range
For example, to fetch logs from April 22, 2026 between 10:00am and 11:00am UTC:
### With Flags
```bash title="Fetch logs within an hour time range"
mcloud logs \
--organization org_123 \
--project proj_123 \
--environment env_123 \
--to 2026-04-22T11:00:00Z
```
### Using mcloud use
```bash title="Fetch logs within an hour time range"
# Run once: mcloud use --organization org_123 --project proj_123 --environment env_123
mcloud logs --to 2026-04-22T11:00:00Z
```
To increase the limit to 1000 log lines in that time range:
### With Flags
```bash title="Fetch logs within an hour time range with a higher limit"
mcloud logs \
--organization org_123 \
--project proj_123 \
--environment env_123 \
--to 2026-04-22T11:00:00Z \
--limit 1000
```
### Using mcloud use
```bash title="Fetch logs within an hour time range with a higher limit"
# Run once: mcloud use --organization org_123 --project proj_123 --environment env_123
mcloud logs --to 2026-04-22T11:00:00Z --limit 1000
```
### Example: Fetch Logs Starting from a Time Until Now
To fetch logs starting from a specific time until now, pass `--from` without `--to`:
### With Flags
```bash title="Fetch logs starting from a specific time until now"
mcloud logs \
--organization org_123 \
--project proj_123 \
--environment env_123 \
--from 2026-04-22T10:00:00Z
```
### Using mcloud use
```bash title="Fetch logs starting from a specific time until now"
# Run once: mcloud use --organization org_123 --project proj_123 --environment env_123
mcloud logs --from 2026-04-22T10:00:00Z
```
### Example: Fetch Logs Until a Time in the Past
To fetch logs until a certain time, pass `--to`. If that time is more than 15 minutes ago, you must also pass `--from` to define a valid time window.
For example, to pass logs until 5 minutes ago, you don't need to specify `--from`:
### With Flags
```bash title="Fetch logs until a time that's within the last 15 minutes"
mcloud logs \
--organization org_123 \
--project proj_123 \
--environment env_123 \
--to 2026-04-22T10:55:00Z # assuming now is 2026-04-22T11:00:00Z
```
### Using mcloud use
```bash title="Fetch logs until a time that's within the last 15 minutes"
# Run once: mcloud use --organization org_123 --project proj_123 --environment env_123
mcloud logs --to 2026-04-22T10:55:00Z # assuming now is 2026-04-22T11:00:00Z
```
However, if you want to fetch logs until 20 minutes ago, you must also specify `--from` to define a valid time window:
### With Flags
```bash title="Fetch logs until a time that's more than 15 minutes ago, with a valid time window"
mcloud logs \
--organization org_123 \
--project proj_123 \
--environment env_123 \
--from 2026-04-22T10:00:00Z \
--to 2026-04-22T10:40:00Z # assuming now is 2026-04-22T11:00:00Z
```
### Using mcloud use
```bash title="Fetch logs until a time that's more than 15 minutes ago, with a valid time window"
# Run once: mcloud use --organization org_123 --project proj_123 --environment env_123
mcloud logs \
--from 2026-04-22T10:00:00Z \
--to 2026-04-22T10:40:00Z # assuming now is 2026-04-22T11:00:00Z
```
***
## Filter Storefront Logs
By default, `mcloud logs` fetches backend logs. To query storefront logs,
pass `--type storefront`:
### With Flags
```bash
mcloud logs \
--organization org_123 \
--project proj_123 \
--environment env_123 \
--type storefront
```
### Using mcloud use
```bash
# Run once: mcloud use --organization org_123 --project proj_123 --environment env_123
mcloud logs --type storefront
```
You can also specify any of the other filters and options with storefront logs, such as `--follow` or `--search`.
