netbox-eosl

Show source-backed hardware end-of-service-life (EOSL) status on your NetBox Devices and Device Types, straight from EOSL.ai — where every date links to the vendor's own end-of-life bulletin.

A panel appears on the right side of each Device and Device Type page: end-of-sale date, end-of-service-life date, the EOSL Exposure Score, a link to the vendor bulletin, and a link to the full EOSL.ai model page. A manage.py eosl_check command audits your whole inventory.

Matching is exact part-number only — the plugin never fuzzy-matches, so it can't put a wrong end-of-life date on the wrong device. If a part number isn't in the database, it says so and offers a search link instead of guessing.

Requirements

NetBox	4.3 or later (uses the models template-extension API)
Python	3.10+
Network	outbound HTTPS to eosl.ai from the NetBox host

Install

# In your NetBox virtual environment
source /opt/netbox/venv/bin/activate
pip install netbox-eosl

Add it to NetBox's configuration.py:

PLUGINS = [
    "netbox_eosl",
]

(Optional) tune it:

PLUGINS_CONFIG = {
    "netbox_eosl": {
        "api_url": "https://eosl.ai",   # data source origin
        "cache_timeout": 86400,          # seconds to cache the lookup table (default 24h)
        "request_timeout": 5,            # network timeout in seconds
    },
}

Then restart NetBox and run migrations (none are added, but this reloads plugins):

python /opt/netbox/netbox/manage.py migrate
sudo systemctl restart netbox netbox-rq

Add netbox-eosl to your local_requirements.txt so upgrades keep it installed.

Use

In the UI — open any Device or Device Type that has a part number set. The "Hardware End-of-Life" card appears in the right column.

Inventory audit — from the NetBox host:

python /opt/netbox/netbox/manage.py eosl_check

EOSL.ai audit — 214 device types
  Past / action recommended:       57
  Ending soon (plan/watch):        18
  Tracked, supported:              44
  Active — no EOL announced:        9
  Not found in EOSL.ai:            79
  No part number set:               7

Past end-of-service-life:
  Cisco Catalyst 3850-48P (WS-C3850-48P-S) — EOSL 2025-10 — 12 in service — https://eosl.ai/system/cisco-catalyst-3850/
  ...

Use --past-only to print just the past-EOSL list (handy in a cron/report).

How matching works

The plugin downloads https://eosl.ai/data/lookup.json (the same part-number → status map that powers the eosl.ai bulk checker) and caches it. For each Device Type it resolves the part_number field (a Device inherits it from its Device Type) in three deterministic, conservative steps:

1. Exact match (case-insensitive).
2. Loose match — ignores spaces/dashes/case, so FortiGate 60E resolves FortiGate-60E.
3. Vendor-gated aliases — expands a manufacturer's short SKU form to the catalogued long form, but only when the NetBox manufacturer matches that vendor. E.g. a Fortinet FG-60E resolves FortiGate-60E, FS-148E → FortiSwitch-148E, FAP-221E → FortiAP-221E. The vendor gate means a non-Fortinet FG-… can never be mis-resolved onto a Fortinet record.

There is no fuzzy or substring matching. No part number, or no confident match → a neutral "not tracked" panel with a search link. Nothing is inferred.

The matching logic lives in netbox_eosl/matching.py (no Django imports) and is unit-tested in tests/ — run python tests/test_matching.py (or pytest).

Data & trust

• Dates come from EOSL.ai, sourced from each vendor's official end-of-life bulletin and linked for verification. Where a vendor publishes no per-model EOSL date, EOSL.ai computes it from the vendor's published support-life policy and labels it "computed".
• This plugin reads public data; it sends none of your inventory anywhere. The only outbound request is fetching the public lookup table.
• Confirm any critical date against the linked vendor bulletin before a purchase, renewal, or migration decision.
