python - Collectd 插件似乎没有启动

Question

问题是我在系统日志文件中没有看到预期的输出。我写了一个Python插件，位于“/home/my/collectd/pyPlugin.py”。 “/etc/collectd/collectd.conf”中的 Collectd 配置(Python 插件在全局变量 true 下启用)具有以下 block :

<Plugin python>
    ModulePath "/home/my/collectd/"
    LogTraces true
    Interactive false
    Import pyPlugin

    <Module pyPlugin>
        Test "arg1" "arg2"
    </Module>
</Plugin>

该插件非常简单:

import collectd

def configer(confObj):
    collectd.info('config called')

def init_fun():
    collectd.info('my py module init called')

def reader(input_data=None):
    collectd.info('my py read called')

def writer(input_data=None)
    collectd.info('my py write called')


collectd.register_config(configer)
collectd.register_init(init_fun)
collectd.register_read(reader)
collectd.register_write(writer)

当我查看“/var/log/syslog”时，我没有看到任何输出。

将其放在collectd.conf文件的顶部:LoadPlugin“syslog”

来自FAQ :

In order to get any output at all, you need to load a log plugin. The two main log plugins are the LogFile and SysLog plugins. We recommend that loading one of those plugins is the first thing you do in your config file, i.e. put the LoadPlugin line at the very top. If no log plugin is loaded, collectd will write to STDERR. After the daemon has forked to the background, you won't be able to see this output anymore, though.

系统日志插件默认显示info级别。另外，要确认 Collectd 正在运行，请查看进程列表或 /etc/init.d/collectd status。
