# Photon Optimizer logs

> Filter Photon Optimizer request logs by domain, client IP, method, and cache status in hosting-panel.net.

**Photon Optimizer logs** shows requests served through Photon Optimizer. Go to **Logs** → **Photon Optimizer Logs**.

The panel looks back **7 days** at most, the same as [Access logs](/docs/grid-hosting/logs/access-logs). Photon only logs requests that go through your Photon hostname. If you have not pointed the site at Photon yet, see [Photon Optimizer](/docs/grid-hosting/photon-optimizer/photon-optimizer).

## Filters

You can filter on:

* **Domain** (Photon hostname, with the origin domain in parentheses)
* **Client IP** (for example `1.2.3.4`)
* **Method** (or **All methods**)
* **Cache status** (for example `HIT`)
* **Per page**

Cache status matches Varnish values such as `HIT`, `MISS`, and `PASS`. The filter accepts letters, `_`, and `-`.

Each row shows **Timestamp**, **Client IP**, **Method**, **Request**, **Status**, **Bytes**, **Cache**, **Savings**, and **POP** (the Photon point of presence that served the request). Savings is a percentage when Photon reduced the payload; otherwise the cell is `-`.
