JBossAS 7.1.1/ WildFly resource monitoring plugin for Nagios using HTTP-JSON based API written in Python

Nagios Plugin Wildfly

This project provides a Nagios plugin for Wildfly resource monitoring. The plugin uses HTTP-JSON based API (JBossAS REST Management API) to collect server statistics. The plugin supports standalone as well as domain mode.

Other plugins need additional SAR or WAR to be installed on the application server. Typically in Enterprise setups; it is sometimes not allowed to perform any additional installations on the target system. The main advantage of this plugin is it leverages the REST API of JBossAS. This allows us to monitor the application server without any additional configurations and installations.

Requirements:

• Nagios

• Python 3 onwards (with requests module used for digest authentication)

• JBossAS 7.1, JBoss EAP 6 or Wildfly 8 onwards

Usage:

The check script supports following options. Details about monitoring different resources is available in respective sub-sections.

server:nagios-plugin-jbossas7 Aparna$ python check_jbossas7.py --help
Usage: check_wildfly.py [options]

  -H HOST, --host=HOST  The hostname you want to connect to
  -P PORT, --port=PORT  The port JBoss management console is runnung on
  -u USER, --user=USER  The username you want to login as
  -m MODE, --mode=MODE  The mode the server is running (standalone or domain)
  -n NODE, --node=NODE  The node if the server is running in domain mode
  -i INSTANCE, --instance=INSTANCE
                        The instance if the server is running in domain mode
  -p PASSWD, --pass=PASSWD
                        The password you want to use for that user
  -W WARNING, --warning=WARNING
                        The warning threshold we want to set

  -A ACTION, --action=ACTION
                        The action you want to take
  -D, --perf-data       Enable output of Nagios performance data
  -m MEMORY_POOL, --memorypool=MEMORY_POOL

If running in domain mode, connect to the domain controller.

Currently the plugin supports monitoring of following resources and sub-systems.

Checks JBossAS status

JVM Memory Utilization

Checks Heap, Non Heap, Old Gen, Eden Space, Perm Gen, and Code cache utilization

Garbage Collection

Checks garbage collection rate

HornetQ Messaging

Checks message queue depths

DataSource Pool Usage

Checks datasource pool utilization

Threading

Checks JVM process thread utilization
