documentation for statistics keys ?

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
