Performance Metrics

URL: /rest/status/performancemetric

GET - lists performance metrics with values and uoms
PUT, POST, DELETE - unimplemented

Filtering URL parameters:

hostgroupid - includes this host group in list. Can be repeated.
hostgroupname - includes this host group in list. If the name is associated with more than one host group, all will be included in the response. Can be repeated.
hostname - filter hosts by this host name. Can specify wildcards with %25. Can be repeated.
hostid - filter hosts by this host id number. Can be repeated.
servicename - filter services by this service check name. Can specify wildcards. Can be repeated.
serviceid - filter services by this service id number. Can be repeated.
metricname - filter metrics by this metric name. Can be repeated.
hs - filter based on this host service. Of the form hostname::servicename. Can be repeated.
hsm - filter based on this host service metric. Of the form hostname::servicename::metricname. Can be repeated.
convertuom - if set, will convert performance data into base units. Eg, if value=1500 and uom=MB, with this flag set, will return value=1500000000 uom=bytes.

Other URL parameters:

rows - limit results by this many rows. Note: if ordering by value, Opsview needs to check for all services before sorting, so we recommend you filter the list of performance metrics to have a smaller set first.
order - you can suffix with _desc to sort descending. If not specified, the order is indeterminate. You can specify multiple values to have secondary sorting (except when sorting by value):
- host
- service
- metric
- value - If this is set, will order by value, then hostname, servicename. Values of empty strings will be sorted to the bottom of the list, regardless of ascending or descending.

Example output:

        "hostname": "opcollector",
        "metricname": "age",
        "servicename": "Opsview Housekeep Age",

        "uom": "",
        "value": "5"
    }, {

It is possible for the value to be the empty string - this means the value is not available (for instance, if the service has a response without any performance dat
