# nfs.get_nfs4_clients

Read information about NFSv4 clients from /proc/fs/nfsd/clients Sample output: [{ “id”: “4”, “info”: { “clientid”: 6273260596088110000, “address”: “192.168.40.247:790”, “status”: “confirmed”, “seconds from last renew”: 45, “name”: “Linux NFSv4.2 debian12-hv”, “minor version”: 2, “Implementation domain”: “kernel.org”, “Implementation name”: “Linux 6.1.0-12-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.52-1 (2023-09-07) x86_64”, “Implementation time”: [0, 0], “callback state”: “UP”, “callback address”: “192.168.40.247:0” }, “states”: [ {

}] —- Description of the fields (all per NFS client) —- ‘clientid’: Hash generated for this client connection ‘address’: The client IP and port. e.g. 10.20.30.40:768

‘status’: The current client status: ‘confirmed’ An active connection. The status will convert to ‘courtesy’ in 90 seconds if not ‘confirmed’ by the client. ‘courtesy’ A stalled connection from an inactive client. The status will convert to ‘expirable’ in 24hr. ‘expirable’ Waiting to be cleaned up.

‘seconds from last renew’: The session timeout counter. See ‘status’ field. Gets reset by confirmation update from the client

‘name’: Supplied by the client. Linux clients might offer something like ‘Linux NFS4.2 clnt_name’. FreeBSD clients might supply a UUID like name

‘minor version’: The NFS4.x minor version. E.G. ‘2’ for NFSv4.2

‘Implementation domain’: NFSv4.1 info - e.g. ‘kernel.org’ or ‘freebsd.org’. ‘Implementation name’: NFSv4.1 info - e.g. equivalent to ‘uname -a’ on the client ‘Implementation time’: NFSv4.1 info - Timestamp (time nfstime4) of client version (maybe unused?)

‘callback state’: Current callback ‘service’ status for this client: ‘UP’, ‘DOWN’, ‘FAULT’ or ‘UNKNOWN’ Linux clients usually indicate ‘UP’ FreeBSD clients may indicate ‘DOWN’ but are still functional

##### Parameter 2: options

#### options

Type: object
Default:
{ "extra": {}, "order_by": [], "select": [], "count": false, "get": false, "offset": 0, "limit": 0, "force_sql_filters": false }

Query options including pagination, ordering, and additional parameters.

No Additional Properties

##

#### Extra

Type: object Default: {}

Extra options are defined on a per-endpoint basis and are described in the documentation for the associated query method.

##

#### Order By

Type: array of string Default: []

An array of field names describing the manner in which query results should be ordered. The field names may also have one of more of the following special prefixes: `-` (reverse sort direction), `nulls_first:` (place any null values at the head of the results list), `nulls_last:` (place any null values at the tail of the results list).

No Additional Items

##### Each item of this array must be:

Example:

    [
        "size",
        "-devname",
        "nulls_first:-expiretime"
    ]

##

#### Select

Type: array Default: []

An array of field names specifying the exact fields to include in the query return. The dot character `.` may be used to explicitly select only subkeys of the query result.

##

#### Count

Type: boolean Default: false

Return a numeric value representing the number of items that match the specified `query-filters`.

##

#### Get

Type: boolean Default: false

Return the JSON object of the first result matching the specified `query-filters`. The query fails if there specified `query-filters` return no results.

##

#### Offset

Type: integer Default: 0

This specifies the beginning offset of the results array. When combined with the `limit` query-option it may be used to implement pagination of large results arrays. WARNING: some query methods provide volatile results and the onus is on the developer to understand whether pagination is appropriate for a particular query API method.

##

#### Limit

Type: integer Default: 0

This specifies the maximum number of results matching the specified `query-filters` to return. When combined wtih the `offset` query-option it may be used to implement pagination of large results arrays.

WARNING: Some query methods provide volatile results and the onus is on the developer to understand whether pagination is appropriate for a particular query API method.

##

#### Force Sql Filters

Type: boolean Default: false

Force use of SQL for result filtering to reduce response time. May not work for all methods.
