Zabbix<\/a> is a fully featured open-source monitoring solution. I wanted to evaluate how easy it is to monitor an application server like WildFly.<\/p>\n\n\n\n

Server Installation<\/h2>\n\n\n\n

First component to install is the server which also requires a database (PostgreSQL in my case). As it was already explained by Daniel’s blog<\/a>, I will not go into too much details. For the server to be able to gather detailed information about WildFly, Zabbix requires a Java gateway<\/a>. When Zabbix software repository is already setup, installation is easy:<\/p>\n\n\n

\ndnf install zabbix-java-gateway\n<\/pre><\/div>\n\n\n
Java gateway will be a proxy to all JMX requests that Zabbix will send to JMX-enabled hosts.<\/p>\n\n\n\n
Configuration file path for Java gateway is \/etc\/zabbix\/zabbix_java_gateway.conf<\/code>. For my installation, I did not need to modify this one, but the main zabbix configuration file: \/etc\/zabbix\/zabbix_server.conf<\/code><\/p>\n\n\n\n
I modified as follow:<\/p>\n\n\n\n
    \n
  • Uncomment line 8 and put IP of Java Gateway server (hosted on same server as Zabbix server).<\/li>\n\n\n\n
  • Uncomment line 16 and put port of Java Gateway. 10052 is the default port.<\/li>\n\n\n\n
  • Uncomment line 24 and put 5.<\/li>\n<\/ul>\n\n\n\n
    File content look like this (extract):<\/p>\n\n\n
    \n[...]\n### Option: JavaGateway\n#       IP address (or hostname) of Zabbix Java gateway.\n#       Only required if Java pollers are started.\n#\n# Mandatory: no\n# Default:\nJavaGateway=&lt;***.***.***.***&gt;\n\n### Option: JavaGatewayPort\n#       Port that Zabbix Java gateway listens on.\n#\n# Mandatory: no\n# Range: 1024-32767\n# Default:\nJavaGatewayPort=10052\n\n### Option: StartJavaPollers\n#       Number of pre-forked instances of Java pollers.\n#\n# Mandatory: no\n# Range: 0-1000\n# Default:\nStartJavaPollers=5\n[...]\n<\/pre><\/div>\n\n\n
    For Java Gateway to connect to WildFly, it will require jboss-client.jar<\/code> library. It can be found under bin\/client<\/code> in WildFly home directory and it must be copied in \/usr\/share\/zabbix-java-gateway\/lib\/<\/code> on Zabbix server.<\/p>\n\n\n\n
    A zabbix-server<\/code> service restart is required for configuration changes to be taken into account and a restart of zabbix-java-gateway<\/code> service for new library.<\/p>\n\n\n\n
    Add JMX Host<\/h2>\n\n\n\n
    During my previous tests of Zabbix, I already added a host with a Zabbix agent into the configuration. Now, I want to add WildFly monitoring which will be done by a adding JMX interface. I need to go in hosts list and edit the host:<\/p>\n\n\n\n
    \"\"<\/figure>\n\n\n\n
    As you can see, I have added an extra template named WildFly Server by JMX<\/em> as well as a JMX interface<\/em> to my existing host. The port corresponds to WildFly management port.<\/p>\n\n\n\n
    Next, we need to define macros (ie. variables) for Java Gateway to connect to WildFly:<\/p>\n\n\n\n
      \n
    • {$WILDFLY.JMX.PROTOCOL}<\/li>\n\n\n\n
    • {$WILDFLY.PASSWORD}<\/li>\n\n\n\n
    • {$WILDFLY.USER}<\/li>\n<\/ul>\n\n\n\n
      \"\"<\/figure>\n\n\n\n
      Finally, I click update.<\/p>\n\n\n\n
      After few seconds and a refresh, I can see that JMX interface become green as well:<\/p>\n\n\n\n
      \"\"<\/figure>\n\n\n\n
      After one more minute, I see new problems raised concerning datasource: They did not have statistics enabled. For that, I just need to enable that in WildFly configuration:<\/p>\n\n\n\n
      \"\"<\/figure>\n\n\n\n
      Likewise for Web subsystem Undertow:<\/p>\n\n\n\n
      \"\"<\/figure>\n\n\n\n
      After that, I can plot a graph for Request per second:<\/p>\n\n\n\n
      \"\"<\/figure>\n\n\n\n
      Note that provided template will only get metrics for http and not https as per discovery rule definition: jboss.as:subsystem=undertow,server=,http-listener=*<\/code><\/p>\n\n\n\n
      This comes from selected template. We could either create our own template or modify existing template, but this is another topic.<\/p>\n","protected":false},"excerpt":{"rendered":"
