Learn about the JBoss AS Integration.

JBoss AS (WildFly) Integration

JBoss Application Server (JBoss AS) is an open-source, cross-platform Java application server developed by JBoss, a division of Red Hat Inc. JBoss AS is an open-source implementation of Java 2 Enterprise Edition (J2EE) that is used for implementing Java applications and other Web-based applications and software.

In addition to setting up the metrics flow, this integration also sets up a dashboard. images/jboss-metrics.png

To see a list of the metrics for this integration, select the integration from https://github.com/influxdata/telegraf/tree/master/plugins/inputs.

JBoss AS (WildFly) Setup

Step 1. Install the Telegraf Agent

If you don’t have the Telegraph agent installed, follow the steps below. Otherwise, continue 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. Install the Jolokia Agent on Your JBoss AS Instance

  1. Download the latest version of the Jolokia WAR-Agent from: https://jolokia.org/download.html.
  2. Rename the jolokia-war-X.X.X.war file to jolokia.war.
  3. Deploy the jolokia.war file into the JBoss AS Instance.
  4. Add an ApplicationRealm user with jolokia role (mandatory for Jolokia 1.6 or later)
  5. Verify the Jolokia agent installation by accessing this URL: http://<address>:<port>/jolokia/version.

The result looks similar to this:

{"request":{"type":"version"},"value":{"agent":"1.3.7","protocol":"7.2","config":{"maxCollectionSize":"0","agentId":"10.152.24.99-29844-172f5788-servlet","debug":"false","agentType":"servlet","serializeException":"false","detectorOptions":"{}","dispatcherClasses":"org.jolokia.jsr160.Jsr160RequestDispatcher","maxDepth":"15","discoveryEnabled":"false","canonicalNaming":"true","historyMaxEntries":"10","includeStackTrace":"true","maxObjects":"0","debugMaxEntries":"100"},"info":{"product":"tomcat","vendor":"Apache","version":"8.5.23"}},"timestamp":1509955465,"status":200}

Step 3. Configure Telegraf Jolokia Input Plugin

First create a file called jboss.conf in /etc/telegraf/telegraf.d and enter the following snippet:

[[inputs.jolokia2_agent]]
urls = ["http://<jboss-host1-ip>:<port>/jolokia","http://<jboss-host2-ip>:<port>/jolokia"]
name_prefix = "jboss."

#username and password are mandatory for Jolokia 1.6 or later
#username = <jolokia role username>
#password = <jolokia role password>

### 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_"

### JBOSS

[[inputs.jolokia2_agent.metric]]
name     = "connectors.http"
mbean    = "jboss.as:https-listener=*,server=*,subsystem=undertow"
paths    = ["bytesReceived","bytesSent","errorCount","requestCount"]
tag_keys = ["server","https-listener"]

[[inputs.jolokia2_agent.metric]]
name     = "connectors.http"
mbean    = "jboss.as:http-listener=*,server=*,subsystem=undertow"
paths    = ["bytesReceived","bytesSent","errorCount","requestCount"]
tag_keys = ["server","http-listener"]

[[inputs.jolokia2_agent.metric]]
name     = "datasource.jdbc"
mbean    = "jboss.as:data-source=*,statistics=jdbc,subsystem=datasources"
paths    = ["PreparedStatementCacheAccessCount","PreparedStatementCacheHitCount","PreparedStatementCacheMissCount"]
tag_keys = ["data-source"]

[[inputs.jolokia2_agent.metric]]
name     = "datasource.pool"
mbean    = "jboss.as:data-source=*,statistics=pool,subsystem=datasources"
paths    = ["AvailableCount","ActiveCount","MaxUsedCount"]
tag_keys = ["data-source"]

Then replace the urls value with your JBoss server URL. Specify your servers with URL matching.

Format:

urls = ["http://<address>:<port>/<jolokia contex>"]

Example:

urls = ["http://10.152.24.99:8080/jolokia"]

To monitor multiple JBoss AS Instance, add additional urls entries:

urls = ["http://jboss.foo.com:8080/jolokia","http://webapp1.foo.com:8080/jolokia","http://wbapp2.foo.com:8080/jolokia"]

Step 4. Enable Statistics in JBoss

You need to enable statistics from the following subsystems to see metrics in Wavefront.

  • Data Sources
  • Web/HTTP - Undertow.

You can use the JBoss Management UI to enable these statistics.

Step 5. Restart Telegraf

Run sudo service telegraf restart to restart your Telegraf agent.
