Jolokia2 Input Plugins

The Jolokia agent and proxy input plugins collect JMX metrics from an HTTP endpoint using Jolokia's JSON-over-HTTP protocol.

Configuration:

Jolokia Agent Configuration

The jolokia2_agent input plugin reads JMX metrics from one or more Jolokia agent REST endpoints.

[[inputs.jolokia2_agent]]
  urls = ["http://agent:8080/jolokia"]

  [[inputs.jolokia2_agent.metric]]
    name  = "jvm_runtime"
    mbean = "java.lang:type=Runtime"
    paths = ["Uptime"]

Optionally, specify SSL options for communicating with agents:

[[inputs.jolokia2_agent]]
  urls = ["https://agent:8080/jolokia"]
  ssl_ca   = "/var/private/ca.pem"
  ssl_cert = "/var/private/client.pem"
  ssl_key  = "/var/private/client-key.pem"
  #insecure_skip_verify = false

  [[inputs.jolokia2_agent.metric]]
    name  = "jvm_runtime"
    mbean = "java.lang:type=Runtime"
    paths = ["Uptime"]

Jolokia Proxy Configuration

The jolokia2_proxy input plugin reads JMX metrics from one or more targets by interacting with a Jolokia proxy REST endpoint.

[[inputs.jolokia2_proxy]]
  url = "http://proxy:8080/jolokia"

  #default_target_username = ""
  #default_target_password = ""
  [[inputs.jolokia2_proxy.target]]
    url = "service:jmx:rmi:///jndi/rmi://targethost:9999/jmxrmi"
    # username = ""
    # password = ""

  [[inputs.jolokia2_proxy.metric]]
    name  = "jvm_runtime"
    mbean = "java.lang:type=Runtime"
    paths = ["Uptime"]

Optionally, specify SSL options for communicating with proxies:

[[inputs.jolokia2_proxy]]
  url = "https://proxy:8080/jolokia"

  ssl_ca   = "/var/private/ca.pem"
  ssl_cert = "/var/private/client.pem"
  ssl_key  = "/var/private/client-key.pem"
  #insecure_skip_verify = false

  #default_target_username = ""
  #default_target_password = ""
  [[inputs.jolokia2_proxy.target]]
    url = "service:jmx:rmi:///jndi/rmi://targethost:9999/jmxrmi"
    # username = ""
    # password = ""

  [[inputs.jolokia2_agent.metric]]
    name  = "jvm_runtime"
    mbean = "java.lang:type=Runtime"
    paths = ["Uptime"]

Jolokia Metric Configuration

Each metric declaration generates a Jolokia request to fetch telemetry from a JMX MBean.

Key Required Description
mbean yes The object name of a JMX MBean. MBean property-key values can contain a wildcard *, allowing you to fetch multiple MBeans with one declaration.
paths no A list of MBean attributes to read.
tag_keys no A list of MBean property-key names to convert into tags. The property-key name becomes the tag name, while the property-key value becomes the tag value.
tag_prefix no A string to prepend to the tag names produced by this metric declaration.
field_name no A string to set as the name of the field produced by this metric; can contain substitutions.
field_prefix no A string to prepend to the field names produced by this metric declaration; can contain substitutions.

Use paths to refine which fields to collect.

[[inputs.jolokia2_agent.metric]]
  name  = "jvm_memory"
  mbean = "java.lang:type=Memory"
  paths = ["HeapMemoryUsage", "NonHeapMemoryUsage", "ObjectPendingFinalizationCount"]

The preceeding jvm_memory metric declaration produces the following output:

jvm_memory HeapMemoryUsage.committed=4294967296,HeapMemoryUsage.init=4294967296,HeapMemoryUsage.max=4294967296,HeapMemoryUsage.used=1750658992,NonHeapMemoryUsage.committed=67350528,NonHeapMemoryUsage.init=2555904,NonHeapMemoryUsage.max=-1,NonHeapMemoryUsage.used=65821352,ObjectPendingFinalizationCount=0 1503762436000000000

Use * wildcards against mbean property-key values to create distinct series by capturing values into tag_keys.

[[inputs.jolokia2_agent.metric]]
  name     = "jvm_garbage_collector"
  mbean    = "java.lang:name=*,type=GarbageCollector"
  paths    = ["CollectionTime", "CollectionCount"]
  tag_keys = ["name"]

Since name=* matches both G1 Old Generation and G1 Young Generation, and name is used as a tag, the preceeding jvm_garbage_collector metric declaration produces two metrics.

jvm_garbage_collector,name=G1\ Old\ Generation CollectionCount=0,CollectionTime=0 1503762520000000000
jvm_garbage_collector,name=G1\ Young\ Generation CollectionTime=32,CollectionCount=2 1503762520000000000

Use tag_prefix along with tag_keys to add detail to tag names.

[[inputs.jolokia2_agent.metric]]
  name       = "jvm_memory_pool"
  mbean      = "java.lang:name=*,type=MemoryPool"
  paths      = ["Usage", "PeakUsage", "CollectionUsage"]
  tag_keys   = ["name"]
  tag_prefix = "pool_"

The preceeding jvm_memory_pool metric declaration produces six metrics, each with a distinct pool_name tag.

jvm_memory_pool,pool_name=Compressed\ Class\ Space PeakUsage.max=1073741824,PeakUsage.committed=3145728,PeakUsage.init=0,Usage.committed=3145728,Usage.init=0,PeakUsage.used=3017976,Usage.max=1073741824,Usage.used=3017976 1503764025000000000

jvm_memory_pool,pool_name=Metaspace PeakUsage.init=0,PeakUsage.used=21852224,PeakUsage.max=-1,Usage.max=-1,Usage.committed=22282240,Usage.init=0,Usage.used=21852224,PeakUsage.committed=22282240 1503764025000000000

Use substitutions to create fields and field prefixes with MBean property-keys captured by wildcards. In the following example, $1 represents the value of the property-key name, and $2 represents the value of the property-key topic.

[[inputs.jolokia2_agent.metric]]
  name         = "kafka_topic"
  mbean        = "kafka.server:name=*,topic=*,type=BrokerTopicMetrics"
  field_prefix = "$1"
  tag_keys     = ["topic"]

The preceeding kafka_topic metric declaration produces a metric per Kafka topic. The name Mbean property-key is used as a field prefix to aid in gathering fields together into the single metric.

kafka_topic,topic=my-topic BytesOutPerSec.MeanRate=0,FailedProduceRequestsPerSec.MeanRate=0,BytesOutPerSec.EventType="bytes",BytesRejectedPerSec.Count=0,FailedProduceRequestsPerSec.RateUnit="SECONDS",FailedProduceRequestsPerSec.EventType="requests",MessagesInPerSec.RateUnit="SECONDS",BytesInPerSec.EventType="bytes",BytesOutPerSec.RateUnit="SECONDS",BytesInPerSec.OneMinuteRate=0,FailedFetchRequestsPerSec.EventType="requests",TotalFetchRequestsPerSec.MeanRate=146.301533938701,BytesOutPerSec.FifteenMinuteRate=0,TotalProduceRequestsPerSec.MeanRate=0,BytesRejectedPerSec.FifteenMinuteRate=0,MessagesInPerSec.FiveMinuteRate=0,BytesInPerSec.Count=0,BytesRejectedPerSec.MeanRate=0,FailedFetchRequestsPerSec.MeanRate=0,FailedFetchRequestsPerSec.FiveMinuteRate=0,FailedFetchRequestsPerSec.FifteenMinuteRate=0,FailedProduceRequestsPerSec.Count=0,TotalFetchRequestsPerSec.FifteenMinuteRate=128.59314292334466,TotalFetchRequestsPerSec.OneMinuteRate=126.71551273850747,TotalFetchRequestsPerSec.Count=1353483,TotalProduceRequestsPerSec.FifteenMinuteRate=0,FailedFetchRequestsPerSec.OneMinuteRate=0,FailedFetchRequestsPerSec.Count=0,FailedProduceRequestsPerSec.FifteenMinuteRate=0,TotalFetchRequestsPerSec.FiveMinuteRate=130.8516148751592,TotalFetchRequestsPerSec.RateUnit="SECONDS",BytesRejectedPerSec.RateUnit="SECONDS",BytesInPerSec.MeanRate=0,FailedFetchRequestsPerSec.RateUnit="SECONDS",BytesRejectedPerSec.OneMinuteRate=0,BytesOutPerSec.Count=0,BytesOutPerSec.OneMinuteRate=0,MessagesInPerSec.FifteenMinuteRate=0,MessagesInPerSec.MeanRate=0,BytesInPerSec.FiveMinuteRate=0,TotalProduceRequestsPerSec.RateUnit="SECONDS",FailedProduceRequestsPerSec.OneMinuteRate=0,TotalProduceRequestsPerSec.EventType="requests",BytesRejectedPerSec.FiveMinuteRate=0,BytesRejectedPerSec.EventType="bytes",BytesOutPerSec.FiveMinuteRate=0,FailedProduceRequestsPerSec.FiveMinuteRate=0,MessagesInPerSec.Count=0,TotalProduceRequestsPerSec.FiveMinuteRate=0,TotalProduceRequestsPerSec.OneMinuteRate=0,MessagesInPerSec.EventType="messages",MessagesInPerSec.OneMinuteRate=0,TotalFetchRequestsPerSec.EventType="requests",BytesInPerSec.RateUnit="SECONDS",BytesInPerSec.FifteenMinuteRate=0,TotalProduceRequestsPerSec.Count=0 1503767532000000000
