Passenger Input Plugin
此插件收集来自 Phusion Passenger 服务的指标。
根据您的环境，此插件可能会创建大量序列，从而对数据库造成高负载。请使用 度量过滤 来管理您的序列基数！
该插件使用 passenger-status 命令行工具。
此插件要求 passenger-status 二进制文件已安装在系统上，并且 Telegraf 可以执行它。
Introduced in: Telegraf v0.10.1 Tags: web OS support: all
全局配置选项
插件支持其他全局和插件配置设置，用于修改指标、标签和字段，创建别名以及配置插件顺序等任务。更多详情请参阅 CONFIGURATION.md。

# Read metrics of passenger using passenger-status
[[inputs.passenger]]
## Path of passenger-status.
##
## Plugin gather metric via parsing XML output of passenger-status
## More information about the tool:
## https://www.phusionpassenger.com/library/admin/apache/overall_status_report.html
##
## If no path is specified, then the plugin simply execute passenger-status
## hopefully it can be found in your PATH

Telegraf 必须有权限执行 passenger-status 命令。在大多数系统上，Telegraf 以 telegraf 用户身份运行。
Series Cardinality
Depending on your environment, this passenger_process measurement of this plugin can quickly create a high number of series which, when unchecked, can cause high load on your database. You can use the following techniques to manage your series cardinality
- Use the measurement filtering options to exclude unneeded tags. In some environments, you may wish to use
tagexcludeto remove thepidandprocess_group_idtags. - Write to a database with an appropriate retention policy.
- Consider using the Time Series Index.
- Monitor your databases series cardinality.
