Jboss : Script de Monitoração via CLI -

Neste post será apresentado um script criado baseado no post de monitoração via cli , este script também pode ser utilizado para servidores monitoração conseguir coletar dados do Jboss.

Update 12/01/2018 – O script foi atualizado para coletar via JSON os nomes das instâncias.

Jboss Cli : Monitoração da JVM

O script abaixo é necessário passar via argumento o host e a instância.

./jboss-mon.sh <OPTION> <HOST> <INSTANCE>

./jboss-mon.sh HeapUsed HOST01 INSTANCE01

Opções de execução do script :

HeapUsed – Heap Utilizada
HeapMax – Heap Máxima da JVM
PermgenUsed – Permgen Utilizado
PermgenMax – Permgen Máximo da JVM
ThreadsCount – Contagem de threads utilizadas por instância
InstanceList – Lista as instâncias no servidor

InstanceDiscovery – Utilizado pelo Zabbix para montar o JSON .

Caso haja dúvidas de quais instâncias existem no servidor utilizamos o exemplo abaixo para listar :

root@server# ./jboss-mon.sh InstanceList HOST01;
INSTANCE01 INSTANCE02

#!/bin/bash

### VARIABLES ###
JCLI_HOME=”/opt/jboss/bin”
JUSER_ADMIN=juser
JUSER_PASS=jpass

# Utilize na variavel DOMAIN_HOST $3 para monitoração simples ou $(hostname) para monitoração via LLD.
DOMAIN_HOST=$3
MGMT_PORT=9990
INSTANCE=$2
