IDO DB 中没有带有 Icinga2 Web2 的历史数据

No Historical Data in IDO DB with Icinga2 Web2

上下文

我正在使用 IDO PostgreSQLIDO MySQLCentOS 7 上使用 Ansible 配置 Icinga2 Web2

我的工作基于出色的 https://github.com/Icinga/icinga2-ansible 角色。我已将项目 (mickael-ange/icinga2-ansible) 分叉以添加更多自动化和支持,例如 IDO PostgreSQL。我正在使用 PostgreSQL 服务器 9.4.

好吧,我最终得到了 icinga2-ansible-web2-ui 角色的一个版本,它使用 IDO PostgreSQL 或 IDO MySQL 自动安装 Icinga2 Web2 无需向导.

我的问题

服务器似乎正常工作,但我无法弄清楚如何在 Icinga2 Web2 界面中获取数据,例如:

我可以创建 CommentsSchedule Downtimes,但它们没有在 UI 中列出。正确处理停机时间。

我可以发送 Notifications 但他们也没有在 UI 中列出。当 SELinux 处于宽容模式时发出通知。

我的问题是:是否有任何 IDO 或 Icinga2 Web2 配置可以让数据库填充评论、停机时间等?

我的/etc/icinga2/features-enabled/ido-pgsql.conf

library "db_ido_pgsql"

object IdoPgsqlConnection "ido-pgsql" {
  user = "icinga"
  password = "icinga"
  host = "localhost"
  database = "icinga"
  table_prefix = "icinga_"
  instance_name = "icinga2"
  instance_description = "icinga2 instance"

  cleanup = {
    downtimehistory_age = 48h
    logentries_age = 31d
  }

  categories = DbCatConfig | DbCatState
}

备注

注一

我已经在 Icinga2 项目和论坛的大部分文档中进行了搜索,但我找不到雪茄。我很惊讶 none 以前遇到过这个问题,所以这可能是我这边的问题。

注2

在 Icinga IRC 频道上聊天并做了更多测试后,我发现 我的问题只发生在 PostgreSQL 后端 上。它与 MySQL 后端一起按预期工作。

我收集了更多关于我的环境的 info/logs。

PostgreSQL 权限

我检查了我的 PostgreSQL icinga 用户权限:

我什至尝试将 postgres 配置为用户以访问后端(icinga_idoicingaweb_ido 资源),但我仍然没有在中列出任何 Comments UI(创建评论后)。

这里是 \dp 命令列出的 PosgreSQL 权限:

<truncated>

此外,我在 PostgreSQL 日志(例如 /var/lib/pgsql/9.4/data/pg_log/postgresql-Thu.log)中没有错误,当从 Icinga UI.

但是,我发现尝试使用 icinga 用户从 pgAdmin UI 浏览 SEQUENCE 时出现错误(postgres 用户没有错误):

< 2016-01-21 03:55:52.436 GMT >STATEMENT:  SELECT last_value, min_value, max_value, cache_value, is_cycled, increment_by, is_called
      FROM icinga_acknowledgements_acknowledgement_id_seq

但我不确定这是否有意义,因为 icinga 用户对 SEQUENCE 只有 USAGE 权限。

比较 PostgreSQL 和 MySQL 后端的调试日志

所以当我创建评论时,我最终比较了两边的 Icinga 调试日志(MySQL IDO 和 PostgreSQL IDO)。我可以看到只有 MySQL 后端才有我正在寻找的 SQL 语句,它们在 icinga_externalcommandsicinga_commentsicinga_commenthistory 表中插入数据。

我没有足够的声誉来提供超过 2 个链接(例如 pastebin)。所以这是日志。

如何重现此问题

对于那些有能力重现问题的人,您可以克隆 mickael-ange/icinga2-ansible Github 存储库(分支:Issue-No-Historical-Data-in-Icinga2-Web2-and-DB)并按照 icinga2-we2-vagrant.md 中的说明进行操作。如果还没有,则需要安装所需的工具。然后使用 librarian-ansible 安装角色依赖项。最后,我写了一个部分(#ido-no-historical-data-in-icinga2-web2-and-db)来重现问题。

提前感谢您抽空阅读到这里! 迈克尔

终于弄明白为什么历史数据没有插入到DB中了,所以我来回复一下自己。

documentation 中所述:

categories Optional. The types of information that should be written to the database.

因此,当我从 ido-pgsql.conf 配置中删除类别时。我重新启动 Icinga2,然后数据按预期写入数据库。 CommentsDowntimes,好吧,我想要的一切现在都在 UI 中列出了。

我还删除了 cleanup 部分,因为它可能也不是我想要的。

最后的ido-pgsql.conf配置:

library "db_ido_pgsql"

object IdoPgsqlConnection "ido-pgsql" {
  user = "icinga"
  password = "icinga"
  host = "localhost"
  database = "icinga"
  table_prefix = "icinga_"
  instance_name = "icinga2"
  instance_description = "icinga2 instance"
}
