Intent-related Metrics

1. Install the metrics app by using either

    a. Include "metrics" in the ONOS_APP configuration list for your ONOS cell BEFORE installing and starting the ONOS cluster:

export ONOS_APPS=drivers,openflow,metrics

    b. Activate the "metrics" app from the ONOS CLI while ONOS is running:

onos> app activate metrics

2. Perform the intent-related operation that should be measured. For example, install a single intent from the CLI to measure the intent installation latency:

onos> add-point-intent --ethSrc 11:11:11:11:11:11 --ethDst 11:11:11:22:22:22 of:0000000000000001/1 of:0000000000000002/1

3. Use the ONOS CLI to obtain the intent event metrics in human-readable format:

onos> intents-events-metrics
Intent Submitted Event Timestamp (ms from epoch)=1414607529207
Intent Submitted Events count=1 rate(events/sec) mean=0.000598 m1=0.000000 m5=0.000016 m15=0.000186
Intent Installed Event Timestamp (ms from epoch)=0
Intent Installed Events count=0 rate(events/sec) mean=0.000000 m1=0.000000 m5=0.000000 m15=0.000000
Intent Withdraw Requested Event Timestamp (ms from epoch)=0
Intent Withdraw Requested Events count=0 rate(events/sec) mean=0.000000 m1=0.000000 m5=0.000000 m15=0.000000
Intent Withdrawn Event Timestamp (ms from epoch)=0
Intent Withdrawn Events count=0 rate(events/sec) mean=0.000000 m1=0.000000 m5=0.000000 m15=0.000000
onos>

4. Use the ONOS CLI to obtain the intent event metrics in JSON format (NOTE: the output is formatted for readability):

onos> intents-events-metrics --json
Intent event metrics (JSON)
{
"intentInstalledRate": {
"count": 0,
"m15_rate": 0.0,
"m1_rate": 0.0,
"m5_rate": 0.0,
"mean_rate": 0.0,
"units": "events/second"
},
"intentInstalledTimestamp": {
"value": 0
},
"intentSubmittedRate": {
"count": 1,
"m15_rate": 0.00018520260981402803,
"m1_rate": 3.5506691362264177e-14,
"m5_rate": 1.543657444105269e-05,
"mean_rate": 0.0005956066011497849,
"units": "events/second"
},
"intentSubmittedTimestamp": {
"value": 1414607529207
},
"intentWithdrawRequestedRate": {
"count": 0,
"m15_rate": 0.0,
"m1_rate": 0.0,
"m5_rate": 0.0,
"mean_rate": 0.0,
"units": "events/second"
},
"intentWithdrawRequestedTimestamp": {
"value": 0
},
"intentWithdrawnRate": {
"count": 0,
"m15_rate": 0.0,
"m1_rate": 0.0,
"m5_rate": 0.0,
"mean_rate": 0.0,
"units": "events/second"
},
"intentWithdrawnTimestamp": {
"value": 0
}
}

Output description:

    a. For every intent-related event type we collect the event rate and the last event timestamp. In the above example, the intent events are:

  1. SUBMITTED: intent was submitted for installation
  2. INSTALLED: intent installation was completed
  3. WITHDRAW_REQUESTED: intent withdraw request was submitted - not supported yet
  4. WITNDRAWN: intent withdraw was completed

    b. The event rate is measured in number of events per second:

  1. "count": total number of events received so far
  2. "mean_rate": the mean rate of the events
  3. "m1_rate": the event rate for the last one minute
  4. "m5_rate": the event rate for the last five minutes
  5. "m15_rate": the event rate for the last fifteen minutes

    c. The last event timestamp is measured in system milliseconds since the epoch: 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970. See http://en.wikipedia.org/wiki/Unix_time+ for details.

5. Additional debug information. You can use the following ONOS CLI command to list the last 100 intent-related events:

onos> onos:intents-events
Event=IntentEvent{time=2014-10-29T11:32:09.205, type=SUBMITTED, subject=PointToPointIntent{id=0x1d285cdd, appId=DefaultApplicationId{id=3, name=org.onlab.onos.cli}, selector=DefaultTrafficSelector{criteria=[ETH_SRC{mac=11:11:11:11:11:11}, ETH_TYPE{ethType=800}, ETH_DST{mac=11:11:11:22:22:22}]}, treatment=DefaultTrafficTreatment{instructions=[]}, ingress=ConnectPoint{elementId=of:0000000000000001, portNumber=3}, egress=ConnectPoint{elementId=of:0000000000000002, portNumber=3}}}

Topology-related Metrics

1. Install the metrics app by using either

    a. Include "metrics" in the ONOS_APP configuration list for your ONOS cell BEFORE installing and starting the ONOS cluster:

export ONOS_APPS=drivers,openflow,metrics

    b. Activate the "metrics" app from the ONOS CLI while ONOS is running:

ONOS metrics feature
onos> app activate metrics

2. Perform the topology-related operation that should be measured. For example, disable a switch port with a link connecting that switch to another one.

3. Use the ONOS CLI to obtain the topology event metrics in human-readable format:

onos> topology-events-metrics
