# smbclient collector
|
||||
The smbclient collector collects metrics from MS SmbClient hosts through perflib
|
||||
|||
|
||||
-|-
|
||||
Metric name prefix | `windows_smbclient`
|
||||
Classes | [Win32_PerfRawData_SMB](https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-smb/)<br/>
|
||||
Enabled by default? | No
|
||||
|
||||
## Flags
|
||||
|
||||
### `--collectors.smbclient.list`
|
||||
Lists the Perflib Objects that are queried for data along with the perlfib object id
|
||||
|
||||
### `--collectors.smbclient.enabled`
|
||||
Comma-separated list of collectors to use, for example: `--collectors.smbclient.enabled=ServerShares`. Matching is case-sensitive. Depending on the smb protocol version not all performance counters may be available. Use `--collectors.smbclient.list` to obtain a list of supported collectors.
|
||||
|
||||
## Metrics
|
||||
Name | Description | Type | Labels
|
||||
-----|-------------|------|-------
|
||||
`windows_smbclient_data_queue_seconds_total` | Seconds requests waited on queue on this share | counter | `server`, `share`|
|

|
||||
`windows_smbclient_requests_queued` | The point in time (current) number of requests outstanding on this share | counter | `server`, `share`|
|
||||
`windows_smbclient_data_bytes_total` | The bytes read or written on this share | counter | `server`, `share`|
|
||||

|
||||
`windows_smbclient_metadata_requests_total` | The metadata requests on this share | counter | `server`, `share`|

|
||||

|
||||
`windows_smbclient_turbo_io_reads_total` | The read requests that go through Turbo I/O | TBD | `server`, `share`|
|
||||
`windows_smbclient_turbo_io_writes_total` | The write requests that go through Turbo I/O | TBD | `server`, `share`|
|
||||
`windows_smbclient_write_bytes_via_smbdirect_total` | The written bytes to this share via RDMA direct placement | TBD | `server`, `share`|

||||
`windows_smbclient_write_bytes_total` | The bytes written on this share | counter | `server`, `share`|
|
||||
`windows_smbclient_write_requests_via_smbdirect_total` | The write requests to this share via RDMA direct placement | TBD | `server`, `share`|
|
||||
`windows_smbclient_write_requests_total` | The write requests on this share | counter | `server`, `share`|
|
||||
`windows_smbclient_read_seconds_total` | Seconds waiting for read requests on this share | counter | `server`, `share`|
|
||||
`windows_smbclient_write_seconds_total` | Seconds waiting for write requests on this share | counter | `server`, `share`|
|
||||
## Useful queries
|
||||
```
|
||||
# Average request queue length (includes read and write).
|
||||
irate(windows_smbclient_data_queue_seconds_total)
|
||||
# Request latency milliseconds (includes read and write).
|
||||
irate(windows_smbclient_request_seconds_total) / irate(windows_smbclient_requests_total) * 1000
|
||||
```
|
||||
## Alerting examples
|
||||
_This collector does not yet have alerting examples, we would appreciate your help adding them!_
