Modify the Statistics Metadata File

The statistics metadata file is the same as the stat.util2.json file shown in Add Resources to the Class Metadata except that you need to add an element for the activity statistic that will be used to partition and reads and writes statistics. Modify the stat.util2.json file to have the following content:

[
    {
        "$schema": "//:stat",
        "description": "reads",
        "id": "//:class.app/util2//:stat.reads",
        "stability": "stable",
        "type": "counter",
        "units": "operations"
    },
    {
        "$schema": "//:stat",
        "description": "writes",
        "id": "//:class.app/util2//:stat.writes",
        "stability": "stable",
        "type": "counter",
        "units": "operations"
    },
    {
        "$schema": "//:stat",
        "description": "errors",
        "id": "//:class.app/util2//:stat.errors",
        "stability": "stable",
        "type": "counter",
        "units": "errors"
},
{
"$schema": "//:stat",
"description": "reads or writes",
"id": "//:class.app/util2//:stat.activity",
"stability": "stable",
"type": "counter",
"units": "operations"
    }
]
