documentation for statistics keys ?

I know they must be somewhere, but cannot find them !.

Previously, https://www.dell.com/community/Isilon/How-to-read-quot-isi-statistics-quot-outputs/m-p/7127077#M9634

one could run 

isi statistics describe --stats

 

however this option seems absent in OneFS v8.1.2

 

So I am trying to find a document/link or man page to gather above info ?

    do isi statistics list first, then isi_classic statistics describe --stats=

    example:

    # isi_classic statistics describe --stats node.ifs.ops.out.rate
    Stat key => Description
    node.ifs.ops.out.rate => Operation output rate to /ifs on the node (ops/sec)

    Hi,

    The statistics interface is part of the OneFS API so a great deal of detail can be extracted using the API. We have an example web app that lets you get this detail at https://github.com/Isilon/isilon_stat_browser but you can also simply query the stats either locally of from a Linux box. Here is an example of querying for information on the statisitic you wanted. My cluster node is cse-sea-h500-1.west.isilon, and I have obscured the password:

    ubuntu-server:~$ curl -sk -u root:XXX 'https://cse-sea-h500-1.west.isilon.com:8080/platform/1/statistics/keys/node.ifs.ops.out.rate' | jq
    {
    "keys": [
    {
    "aggregation_type": "avg",
    "base_name": "node.ifs.ops.out",
    "default_cache_time": 0,
    "description": "Operation output rate to /ifs on the node (ops/sec)",
    "key": "node.ifs.ops.out.rate",
    "policies": [
    {
    "interval": 5,
    "persistent": false,
    "retention": 4200
    }
    ],
    "policy_cache_time": 7,
    "real_name": null,
    "scope": "node",
    "type": "double",
    "units": "operations per second"
    }
    ]
    }

    As you can see from the above this statistics is only available live. Some of the stats are also sampled at a lower rate and persisted to the historic stats database on-cluster for two weeks.

    HTH,

    Tim
