The Solr Admin API lets you send commands to Solr through Fusion’s proxy service.
This allows you to protect your Solr instances from outside connections, and apply roles and user permissions from Fusion when running Solr commands.
Requests sent to this API are subject to access restrictions above the collection level.

*Note that because one searchCluster may host several collections, it is not recommended to use this with a collection-level command (such as a query, or document update).*

## Example

Here is an example to GET all CORE [MBeans](https://solr.apache.org/guide/solr/latest/deployment-guide/mbean-request-handler.html) for the 'default' searchCluster, formatted in JSON:

**REQUEST**

```sh wrap  theme={"dark"}
https://FUSION_HOST:8764/api/solrAdmin/default/admin/mbeans?cat=CORE&wt=json
```

**RESPONSE**

```json wrap  theme={"dark"}
{
    "responseHeader": {
        "status": 0,
        "QTime": 1
    },
    "solr-mbeans": [
        "CORE",
        {
            "searcher": {
                "class": "org.apache.solr.search.SolrIndexSearcher",
                "version": "1.0",
                "description": "index searcher",
                "src": null
            },
            "core": {
                "class": "collection1",
                "version": "1.0",

                "src": null
            },
            "Searcher@435cf502[collection1] main": {
