在运行procstat时，有人知道解决整个telegraf用户权限问题的方法吗？ （我的目标是为几个流程/服务获取打开的文件描述符）
当我运行它时，influx不会收集我正在寻找的文件描述符信息pgrep_serviceprocess_num_fds。
telegraf配置：
[[inputs.filestat]]
files = ["/var/run/*/*.pid","/var/run/*.pid"]
[[inputs.procstat]]
user = "root"
#pid_file = "/var/run/grafana/grafana-server.pid"
#systemd_unit = "sshd.service"
prefix = "pgrep_serviceprocess"
[[outputs.influxdb]]
url = "http://localhost:8086"
database = "file"
以telegraf用户身份运行时，它实际上无法收集任何数据：
[root@grafana ~]# sudo -u telegraf bash -c 'telegraf -test -config /etc/telegraf/telegraf.d/file.conf' | grep sshd | sed 's/,/\n/g'

以telegraf用户的身份运行root，我得到的pgrep_serviceprocess_num_fds指标还不错。但是，当然，当运行telegraf时，它将以telegraf用户身份运行。对于我来说，这很奇怪，因为procstat模块实际上对收集文件描述符数据毫无用处。除非您以root用户身份运行Telegraf（不好）或添加ACL magic。
