不支持Zabbix psql主动监视

Question

我有Zabbix代理处于活动模式且psql监控不起作用。它不受支持，我不知道这意味着什么......

#   For example, to retrieve the ID of user 'zabbix':
#   Alias=zabbix.userid:vfs.file.regexp[/etc/passwd,^zabbix:.:([0-9]+),,,,\1]

Answer 1

尝试增加代理日志级别，然后重新检查代理日志。可能是PSQL权限问题。我还建议您升级代理。然后，您可能会在Zabbix UI中看到错误消息，而不是ZBX_UNSUPPORTED。

Answer 2

您的代理看起来没有配置为具有这些项密钥所需的任何psql.*用户参数，除非您在某些包含的文件中有这些参数。

您应该从获得此模板的相同位置获取用户参数配置。看起来您已将模板与相关主机取消链接，但这可能不是一个好主意，最好保持模板链接。

考虑阅读官方手册中的Zabbix userparameters，应该更清楚地了解这是如何工作的。

有人建议libzbxpgsql loadable module应该提供这些项目键。如果是这样，将代理DebugLevel参数设置为4并检查更多有用的错误消息可能会有所帮助，但这可能是您已经提供的＆＃34;详细日志＆＃34;。如果是这样，请仔细检查Zabbix用户（或您的代理运行的任何用户）是否可以使用＆＃34; postgres＆＃34;连接到127.0.0.1:5432上的PostgreSQL。作用。

请注意，应该与该可加载模块一起使用的template具有完全不同的项目键 - 您的项目密钥以psql.开头，而模板名称则以pg.开头。最简单的可能是删除所有以前的配置并重新安装最新版本的模块和模板。
