我有一个针对ElasticSearch的systemd配置的问题.

[Unit]
Description=platform-elasticsearch
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
User={{ app_user }}
Group={{ app_group }}
Environment=ES_PATH_CONF=/platform/opt/elasticsearch-{{ elasticsearch.version }}/config
Environment=JAVA_HOME=/platform/opt/jdk{{ jdk.major_version }}_{{ jdk.minor_version }}

ExecStart=/platform/opt/elasticsearch-{{ elasticsearch.version }}/bin/elasticsearch

# When a JVM receives a SIGTERM signal it exits with code 143
SuccessExitStatus=143 0

[Install]
WantedBy=multi-user.target

这似乎不允许我配置vm.max_map_count设置.

我有一个travis构建工作配置在:https: //travis-ci.org/caffeinated-expert/frisbee

我一直在推动提交,但travis不会接受它们.

如果我知道MBean的名称,我就能获得属性信息,但我试图监视的应用程序生成随机命名的MBean,因此需要能够在JMX中查询域中注册的MBean列表.

这是JConsole中视图的一个示例,以及我想要动态获取的内容.

下面是我编写的代码,它能够提取属性,已注册的域,但我似乎无法获取域中MBean的实际列表.

    import javax.management.remote.JMXConnector;
    import javax.management.remote.JMXConnectorFactory;
    import javax.management.remote.JMXServiceURL;
    import java.lang.management.ManagementFactory;

    import sys, cmd, socket, optparse
    from urlparse import urljoin
    from cmd import Cmd

    def get_connection(host, port):
        serviceURL = str()
        serviceURL = "service:jmx:rmi:///jndi/rmi://"
        serviceURL = serviceURL + host + ":" + str(port) + "/jmxrmi"

        url =  javax.management.remote.JMXServiceURL(serviceURL);
        connector = javax.management.remote.JMXConnectorFactory.connect(url);
        global remote
        remote = connector.getMBeanServerConnection();


    def get_domain_list():
        domainList = []
        get_connection('dt2apps2102', 8004)
        domainList = remote.getDomains()
        return domainList

    def print_domain_list():
        domainList = get_domain_list()
        for element in domainList:
            print element

    def get_domain_objects(domain): …
