| # Cache Inspector Plugin |
| |
| The cache inspector plugin allows you to view the contents of the cache in a browser. Point your browser at `http://<yourcacheiporhostname:yourcacheport>/_cacheinspect` to get started. Access to this endpoint is limited to the IP ranges defined in the `stats` object of the global configuration. |
| |
| Example output: |
| |
| ``` |
| Jump to: disk my-disk-cache-two |
| |
| |

| * Number of elements in LRU: 54 |
| * Objects in cache sorted by Least Recently Used on top, showing only first 100 and last 100: |

| The following querystrings can be used: |
| |
| - `cache=<cachename>` |
| Only display the contents of the cache `<cachename>`. Use `cache=` (empty cachename) for the default memory cachename `""`. |
| - `head=<number>` |
| Number of items to list from the top of the top of the LRU. Default is 100. |
| - `key=<keystring>` |
| Show details page of the given key. |
| - `search=<searchstring>` |
| List only items that have `<searchstring>` in the key. This overrules `<head>` and `<tail>`, when search is used these are ignored. |
| - `tail=<number>` |
| Number of items to list from the bottom of the top of the LRU. Default is 100. |
