# Telegraf plugin: Jolokia #### Configuration ```toml # Read JMX metrics through Jolokia [[inputs.jolokia]] ## This is the context root used to compose the jolokia url ## NOTE that Jolokia requires a trailing slash at the end of the context root context = "/jolokia/" ## This specifies the mode used # mode = "proxy" # ## When in proxy mode this section is used to specify further ## proxy address configurations. ## Remember to change host address to fit your environment. # [inputs.jolokia.proxy] # host = "127.0.0.1" # port = "8080" ## Optional http timeouts ## ## response_header_timeout, if non-zero, specifies the amount of time to wait ## for a server's response headers after fully writing the request. # response_header_timeout = "3s" ## ## client_timeout specifies a time limit for requests made by this client. ## Includes connection time, any redirects, and reading the response body. # client_timeout = "4s" ## List of servers exposing jolokia read service [[inputs.jolokia.servers]] name = "as-server-01" host = "127.0.0.1" port = "8080" # username = "myuser" # password = "mypassword" ## List of metrics collected on above servers ## Each metric consists in a name, a jmx path and either ## a pass or drop slice attribute. ## This collect all heap memory usage metrics. [[inputs.jolokia.metrics]] name = "heap_memory_usage" mbean = "java.lang:type=Memory" attribute = "HeapMemoryUsage" ## This collect thread counts metrics. [[inputs.jolokia.metrics]] name = "thread_count" mbean = "java.lang:type=Threading" attribute = "TotalStartedThreadCount,ThreadCount,DaemonThreadCount,PeakThreadCount" ## This collect number of class loaded/unloaded counts metrics. [[inputs.jolokia.metrics]] name = "class_count" mbean = "java.lang:type=ClassLoading" attribute = "LoadedClassCount,UnloadedClassCount,TotalLoadedClassCount" ``` #### Description The Jolokia plugin collects JVM metrics exposed as MBean's attributes through jolokia REST endpoint. All metrics are collected for each server configured. See: https://jolokia.org/ # Measurements: Jolokia plugin produces one measure for each metric configured, adding Server's `jolokia_name`, `jolokia_host` and `jolokia_port` as tags.
