Telegraf & InfluxDB:如何将 PROCSTAT 的 pid 从字段转换为标签?
Telegraf & InfluxDB: how to convert PROCSTAT's pid from field to tag?
总结:我正在使用 telegraf 将 procstat 导入 InfluxDB。 我想将 pid 从整数字段转换为 TAG,以便我可以在 Influx 中对其进行分组。
详情:
经过大量搜索后,我在某个网站上发现了以下内容,但它似乎在做相反的事情(将标签转换为字段)。我不确定如何从中推导出相反的转换语法:
[processors]
[[processors.converter]]
namepass = [ "procstat",]
[processors.converter.tags]
string = [ "cmdline",]
我正在使用 Influx 1.7.9
将 pid 转换为标签的正确处理器配置如下。
[processors]
[[processors.converter]]
namepass = [ "procstat"]
[processors.converter.fields]
tag = [ "pid"]
请参考转换器处理器插件的文档
https://github.com/influxdata/telegraf/tree/master/plugins/processors/converter
在最新版本的 telegraf 中,pid 可以通过在输入插件配置中指定来存储为标签。这里不需要转换器处理器。
在配置中提及pid_tag = true
。但是,请注意当进程寿命很短时将 pid 作为标记对性能的影响。
P.S: 你应该尝试将你的 telegraf 版本升级到 1.14.5。此版本中对 procstat 插件进行了性能改进修复。
插件配置参考https://github.com/influxdata/telegraf/tree/master/plugins/inputs/procstat
示例配置。
# Monitor process cpu and memory usage
[[inputs.procstat]]
## PID file to monitor process
pid_file = "/var/run/nginx.pid"
## executable name (ie, pgrep <exe>)
# exe = "nginx"
## pattern as argument for pgrep (ie, pgrep -f <pattern>)
# pattern = "nginx"
## user as argument for pgrep (ie, pgrep -u <user>)
# user = "nginx"
## Systemd unit name
# systemd_unit = "nginx.service"
## CGroup name or path
# cgroup = "systemd/system.slice/nginx.service"
## Windows service name
# win_service = ""
## override for process_name
## This is optional; default is sourced from /proc/<pid>/status
# process_name = "bar"
## Field name prefix
# prefix = ""
## When true add the full cmdline as a tag.
# cmdline_tag = false
## Add the PID as a tag instead of as a field. When collecting multiple
## processes with otherwise matching tags this setting should be enabled to
## ensure each process has a unique identity.
##
## Enabling this option may result in a large number of series, especially
## when processes have a short lifetime.
# pid_tag = false
