Cannot get limits ({str(e)})

Error message

Cannot get limits ({str(e)})

What it means

Raised when getAllLimitsAsDict() fails on the limits endpoint, returned as HTTP 404. Limits describe care/warning/critical thresholds across plugins; failure means the limits model could not be composed. Underlying exception text is included.

Solutions

1. Inspect the server log for the wrapped exception to find the offending plugin
2. Validate the [limits] sections and plugin config keys in glances.conf
3. Disable suspect plugins and retry the endpoint

try:
    limits = httpx.get(f'{BASE}/api/4/all_limits').json()
except httpx.HTTPStatusError as e:
    if e.response.status_code == 404:
        limits = {}  # limits are optional metadata
    else:
        raise

When it happens

Trigger: GET /api/4/all_limits when aggregating per-plugin limits raises — e.g., a plugin with a malformed limits configuration (glances.conf) or a missing get_limits implementation.

Common situations: Custom configuration files with invalid section keys, or third-party/out-of-tree plugins that do not implement the limits API.
