Influxdb 没有显示由 collectd exec 插件推送的测量名称

Question

正在使用 collectd 收集系统指标并将其推送到 influx db。

为了监控正在运行的过程，我编写了一个脚本，利用 collectd exec 插件将我的自定义指标推送到 influx db...我的 exec 插件脚本是

#!/bin/bash
tmpfile=$(mktemp)
HOSTNAME="${COLLECTD_HOSTNAME:-slave1-collectd}"
INTERVAL="${COLLECTD_INTERVAL:-6}"
while sleep "$INTERVAL"; do
sudo systemctl list-units --type service --all | grep running | awk -v OFS='\t' '{ print $1, $2, $4 }' > "$tmpfile"
done

我的 collectd conf 文件

<Plugin exec>
        Exec developer "/home/developer/process.sh"
<Plugin>

如果我在 influxdb 中运行命令 show measure，它显示的是其他插件的测量值而不是执行插件：

cpu_value
df_value
disk_io_time
disk_read
disk_value
disk_weighted_io_time
disk_write
interface_rx
interface_tx
load_longterm
load_midterm
load_shortterm
memory_value
processes_majflt
processes_minflt
processes_processes
processes_read
processes_rx
processes_syst
processes_threads
processes_tx
processes_user
processes_value
processes_write
table_value
uptime_value
users_value

谁能帮帮我吗！

我的最终目标是监控所有正在运行的服务，如下所示

[developer@slave1-collectd ~]$ systemctl list-units --type service --state=running
UNIT                       LOAD   ACTIVE SUB     DESCRIPTION

tuned.service              loaded active running Dynamic System Tuning Daemon

我想推送所有正在运行的进程及其单元名称和状态，例如 sshd、kafka、tsdb、collectd、grafana（我想在 Grafana 仪表板上监控所有这些 systemctl 服务）

#!/bin/bash

HOSTNAME="${COLLECTD_HOSTNAME:-`hostname -f`}"
INTERVAL="${COLLECTD_INTERVAL:-10}"
PORT=6379

while sleep "$INTERVAL"
do
b=$(systemctl list-units --type service --all | awk 'BEGIN{print "Service State Status"};$4 ~ /^running$/{print $1,$2,$4}' | column -t )

echo "PUTVAL $HOSTNAME/vs_processes/if_octets  interval=$INTERVAL N:$b"
done

当我启动 collectd 时出现错误：parse_value：无法将字符串解析为派生词：“服务”。
