API integration to generate the hosts list with the monitoring data

[anivargi]

Tendrl API needs to provide the storage, cpu usage, memory and alert count per host in the hosts list API

@brainfunked @nthomas-redhat please review.

@anivargi @shtripat @nthomas-redhat @brainfunked @gnehapk Ideally 'key' of Object should be some "static name" in order to access the value of it . it should not be dynamic (in this case - node_id) as such in response format -

Example: {

"nodes":[
    {
        "3038c577-b233-4513-926d-a8a1ac63b0a3":  {

               "fqdn":"dhcp43-189.lab.eng.blr.redhat.com",
               "machine_id":"a2e4163a1a8e4b28afb1a17e6a1d9962",
               "node_id":"3038c577-b233-4513-926d-a8a1ac63b0a3"

        },
        "stats":{}
    }
]

}

Here , i am fine with "stats" key which is static name. and also we can access the value of it using dot operator . but for "3038c577-b233-4513-926d-a8a1ac63b0a3" , it can have any node-id which is dynamic (we don't know what it can have because it is not static name). and accessing this value in UI will be tricky and difficult . Can we have some static name instead of dynamic id?

Ideally it should be like this :

Example: {

"nodes":[
    {
        "detail":  {

               "fqdn":"dhcp43-189.lab.eng.blr.redhat.com",
               "machine_id":"a2e4163a1a8e4b28afb1a17e6a1d9962",
               "node_id":"3038c577-b233-4513-926d-a8a1ac63b0a3"

        },
        "stats":{}
    }
]

}

Here all keys ( object properties name ) is static name .. not dynamic key like node-id. Actually in UI , we should have well known key (property name) for any object to get that value . i don't know about back-end how to access this data . but in UI we should have well know key for object in order to access that data . But anyway we have work-around for this in javascript . but first i am thinking about if it is possible to show the data into UI directly without doing any logic on response data.

@anivargi I observed that 'percent-used' (property name) is coming for all stats data (storage, cpu, memory) But ideally property name of any object should not contain any special characters in JavaScript. Here i found that 'percent-used' which contain '-' hyphen , which is not acceptable by JavaScript object. Can we have underscore instead of this ?

[gnehapk]

@anivargi Can we have multiple pools associated with a ceph cluster? If yes then the "pools" attribute in the clusterList.json should be an array instead of object. Please correct me if I am wrong.

[gnehapk]

@anivargi We cant see any data for "RBD" in clusterList.json response. Can you please check whether it is there with some other name?

Please add https://github.com/Tendrl/usmqe-tests/issues/15 to reference of testing.

@anivargi @brainfunked @nthomas-redhat @shtripat i need API response format for GetNodeList which will contain info about cluster to be import.

[anivargi]

@gnehapk The RBD' details will be automatically available when its populated in etcd, I unfortunately don't know the attributes and the structure of how it will be represented in GetClustersList response.

@kamleshverma1 I am working on adding the details.
