Apache ActiveMQ Integration
Apache ActiveMQ is an open source message broker written in Java together with a full Java Message Service client.
In addition to setting up the metrics flow, this integration also sets up a dashboard.
To see a list of the metrics for this integration, select the integration from https://github.com/influxdata/telegraf/tree/master/plugins/inputs.
Apache ActiveMQ Setup
Step 1. Install the Telegraf Agent
This integration uses Jolokia to extract metrics from ActiveMQ, and the Jolokia input plugin for Telegraf. If you’ve already installed Telegraf on your server(s), you can skip to Step 2.
Log in to your product instance and follow the instructions on the Setup tab to install Telegraf and a Wavefront proxy in your environment. If a proxy is already running in your environment, you can select that proxy and the Telegraf install command connects with that proxy. Sign up for a free trial to check it out!
Step 2. Configure the Telegraf Jolokia Input Plugin
First, create a file called activemq.conf in /etc/telegraf/telegraf.d and enter the following snippet:
[[inputs.jolokia2_agent]]
urls = ["http://localhost:8161/api/jolokia"]
name_prefix = "activemq."
username = "admin"
password = "admin"
### JVM Generic
[[inputs.jolokia2_agent.metric]]
name = "OperatingSystem"
mbean = "java.lang:type=OperatingSystem"
paths = ["ProcessCpuLoad","SystemLoadAverage","SystemCpuLoad"]
[[inputs.jolokia2_agent.metric]]
name = "jvm_runtime"
mbean = "java.lang:type=Runtime"
paths = ["Uptime"]
[[inputs.jolokia2_agent.metric]]
name = "jvm_memory"
mbean = "java.lang:type=Memory"
paths = ["HeapMemoryUsage", "NonHeapMemoryUsage", "ObjectPendingFinalizationCount"]
[[inputs.jolokia2_agent.metric]]
name = "jvm_garbage_collector"
mbean = "java.lang:name=*,type=GarbageCollector"
paths = ["CollectionTime", "CollectionCount"]
tag_keys = ["name"]
[[inputs.jolokia2_agent.metric]]
name = "jvm_memory_pool"
mbean = "java.lang:name=*,type=MemoryPool"
paths = ["Usage", "PeakUsage", "CollectionUsage"]
tag_keys = ["name"]
tag_prefix = "pool_"
### ACTIVEMQ
[[inputs.jolokia2_agent.metric]]
name = "queue"
mbean = "org.apache.activemq:brokerName=*,destinationName=*,destinationType=Queue,type=Broker"
paths = ["QueueSize","EnqueueCount","ConsumerCount","DispatchCount","DequeueCount","ProducerCount","InFlightCount"]
tag_keys = ["brokerName","destinationName"]
[[inputs.jolokia2_agent.metric]]
name = "topic"
mbean = "org.apache.activemq:brokerName=*,destinationName=*,destinationType=Topic,type=Broker"
paths = ["ProducerCount","DequeueCount","ConsumerCount","QueueSize","EnqueueCount"]
tag_keys = ["brokerName","destinationName"]
[[inputs.jolokia2_agent.metric]]
name = "broker"
mbean = "org.apache.activemq:brokerName=*,type=Broker"
paths = ["TotalConsumerCount","TotalMessageCount","TotalEnqueueCount","TotalDequeueCount","MemoryLimit","MemoryPercentUsage","StoreLimit","StorePercentUsage","TempPercentUsage","TempLimit"]
tag_keys = ["brokerName"]
Then, replace the urls, username and password values with your ActiveMQ server values. Specify your servers with URL matching.
Format:
urls = ["http://<address>:<port>/api/jolokia"]
username = [username]
password = [password]
Example:
urls = ["http://localhost:8161/api/jolokia"]
username = "admin"
password = "admin"
Step 3. Restart Telegraf
Run sudo service telegraf restart to restart your Telegraf agent.
