REST API and performance stats

The OneFS 8.0.0 API doc is

OneFS 8.0.0 API Reference

but it does not list all the specific sub-keys for the /platform/1/statistics call.

An easy way to explore what statistics are available is using the CLI:

# isi statistics list keys

and then interactively querying potentially interesting keys:

# isi statistics query current --nodes=all --keys=cluster.protostats.nfs3

[...]

To get to the API call, insert --debug

# isi --debug statistics query current --nodes=all --keys=cluster.protostats.nfs3

2017-04-24 18:27:04,246 DEBUG rest.py:56: >>>GET ['1', 'statistics', 'current']

2017-04-24 18:27:04,246 DEBUG rest.py:58:    args={'keys': ['cluster.protostats.nfs3'], '___noid': 'True', 'degraded': 'False', 'nodes': 'all', 'show_nodes': 'True'}

from which you can derive the API URL path:

/platform/1/statistics/current?keys=cluster.protostats.nfs3&___noid=True& ... etc ...

The debug output also includes the HTTP feedback from the server in JSON format,

so you can peek at what your code will need to deal with.

The above API document also shows some newer calls of the form

/platform/3/statistics/summary/...

which AFAIK have no CLI equivalents, but are worth a shot right by the API itself.

An nice overview of which API calls are used by the InsightIQ tool is here:

in combinattion with

Let me know when you have specific questions on statistics or other calls;

I've done quite some work with the Isilon API.
