Can XMCLI commands like 'show-reports' output be accessed via REST?
Found a the following command 'show-report report-id=9' that displays all the CPU utilization for all storage controllers. Currently creating a report via REST, but walking the tree of JSON for each storage controller to view this information takes a lot of requests accessing this output with 1 rest call would simplify the process. If this is possible what is the syntax of the JSON string (i.e. something like.. https://xmsserver/api/json/v2/types/???? The output of the command at cli looks close to a JSON format - wondering if its truly available via REST. Example of xmcli below:
xmcli (narn1)> show-report report-id=9
Name:
Index: 9

The equivalent interface to get "Reports" data from the REST API is the "performance" object.
Unlike the GUI/CLI where you create a report and then run it to get the data (like you've done above - although that's probably one of the pre-configured reports), from the REST API you just get raw access to whatever data you request - both real time and historic.
For example, if you want to get the CPU utilization (aka "XEnv" utilization in XtremIO-speak) for the past hour, in one minute granualarity, then you'd use :
https://xms.example.com/api/json/v2/types/performance?entity=XEnv&time-frame=last_hour&granularity=one_minute
This would give you 60 timepoints, each with one entry for each of the XEnv's (ie, 4 for a single brick, 8 for a dual brick, etc). Each of these will looks like :
[
1471297740000,
"43f43133972d4a30b7e26d9a70f047dc",
"X2-SC1-E2",
6,
25.5
],
which if you scroll to the bottom of the results you'll get the details of what each one is :
"members": [
"timestamp",
"guid",
"name",
"index",
"avg__cpu_usage"
],
timestamp is in "epoch" time in microseconds. guid is just an internal unique identifier for that X-Env. name is the friendly name of the XEnv. Index is an internal index number. avg__cpu_usage is the one you're interested in, which is the average utilization over the 1 minute period being reported on.
If you want to know the utilization "right now" then you can pass a "time-frame" option of "real-time", but be aware that you'll occasionally get back an empty result for this if you hit it right as it's updating the data - the better option if you absolutely need live data is to query each of the XEnv objects (/api/json/v2/types/xenvs/X), but as you've said that needs a number of calls to achieve it.
