+# smb collector
+
+The smb collector collects metrics from MS Smb hosts through perflib
+=======
+
+
+|||
+-|-
+Metric name prefix  | `smb`
+Classes 			| [Win32_PerfRawData_SMB](https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-smb/)<br/> 
+Enabled by default? | No
+
+## Flags
+
+### `--collectors.smb.list`
+Lists the Perflib Objects that are queried for data along with the perlfib object id
+
+### `--collectors.smb.enabled`
+Comma-separated list of collectors to use, for example: `--collectors.smb.enabled=ServerShares`. Matching is case-sensitive. Depending on the smb installation not all performance counters are available. Use `--collectors.smb.list` to obtain a list of supported collectors.
