The SDN controller has a subsystem for tracking metric values over time. Metric values are help as a time series which becomes available to the user via JMX or may be persisted to disk. For metric values that are persisted to disk the time‐series values for each individual metric may be persisted at intervals of 1, 5, or 15 minutes; the component or application creating the metric may choose to use the default persistence. Each persisted value represents the value of the metric over the elapsed interval represented by the persisted value. Persisted metric values are retained on the controller disk for the period of time configured via the metric manager configuration, see “Metric manager component”. Persisted metric values may be extracted from the controller using a series of REST calls.
Persisted value
Consider the value of a counter that incremented from 100 to 145 during a 5 minute interval. By taking the value at the end of the interval (145), less the value at the start of the interval (100) the value persisted for the interval would be 45.
The amount of time during the interval over which the metric value was accrued is also persisted.
If the counter value was accrued over only the last 3 minutes of the 5 minute interval, then the normalized rate of accrual over the interval would be 15 counts per minute or 75 counts for the entire 5 minute interval.
The user can inspect the most recent value of the exposed metric using any JMX client (e.g. jconsole). The values exposed will show the absolute value of each such metric. Metric values that are retained only in memory and not exposed to the user via persistence and/or JMX may be used internally by a component or application.
The metric REST API consists of several distinct commands that may be used in combination to determine which metrics have persisted time‐series values resident on the controller, what each metric represents, and to retrieve time series values for specific metrics of interest. Note this API operates only on a single controller at a time; it is not team‐aware and does not return values that span a controller team. The metrics applications commands will display the application IDs – including the controller itself – that have persisted metrics to disk.
Displaying the application IDs
The metrics/apps command will display the application IDs for applications – including the controller itself – that have persisted metrics to disk. In this example, only the base controller itself has persisted metrics to disk.
All metrics available
The following command lists all of the metrics available for a specific application (the controller itself in this example); because of the number of metrics available the output is cut off.
NOTE: This output describes the metrics; it does not represent the time‐series values for them. | |

Result
For each metric listed, one can see the its type, its associated application ID, its name, its primary and secondary tags, whether it is persisted, whether it is exposed via JMX, and its summary interval. Also displayed for each metric is the unique ID (uid) assigned to the metric on the controller. Other metric REST API calls can be used to view specific subsets of this data.
Secondary tags associated with a specific application
The secondary tags associated with a specific application are listed using the following REST call.
Curl output for app_id=com.hp.sdn
{"secondaries":["nioDirectMemory","operatingSystem","threads","garbageCollection", "memoryNonHeap","memoryHeap","memoryTotal","nioMappedMemory"]}Result
Several secondary tags are associated with the primary tag “jvm” along with several subcategories of “jvm” metric: “memoryHeap” metrics and “threads” metrics among others.
Metric names associated with a specific application
Metric names associated with a specific application are displayed using the following call.
Curl output for app_id=com.hp.sdn
{"names":["averageBufferUsedBytes","countDeadlocked","bufferCapacityBytes","count", "countNew","bufferCount","countWaiting","fileDescriptorsOpen","uptimeMs","cou ntTerminated", "elapsedMs","countTimedWaiting","countDaemon","countBlocked","fileDescriptorsUsage", "averageBuff erCapacityBytes","cpuLoadSystem","countTotal","bufferUsedBytes","usedBytes", "usage","countNonDaemon","countRu nnable","cpuLoadJvm","committedBytes"]}
Primary and secondary tags
Curl output for app_id=com.hp.sdn
primary_tag=jvm&secondary_tag=memoryHeap): {"names":["usedBytes","usage","committedBytes"]}Result
Metric names are specific to JVM heap memory. The UID can be obtained once the specific metric of interest is identified via the earlier call. Optional query parameters to filter the output and list the metrics associated with an application ID may be employed.
Filter primary, secondary and metric name
Filter for a primary tag of “jvm”, a secondary tag of “memoryHeap”, and a metric name of “usedBytes”.

Time‐series data for a metric
The following example shows time‐series data for a metric. The time for which the actual metric value was accrued is shown in each 18 interval in number of milliseconds spanned. The “ast” value is the metric value for the indicated time, spanning the indicated number of milliseconds ending at that time.
