将指标从Telegraf发送到Prometheus [英] Sending metrics from telegraf to prometheus
问题描述
我在同一主机上运行prometheus和telegraf.
I'm running prometheus and telegraf on the same host.
我正在使用一些输入插件:
I'm using a few inputs plugins:
- inputs.cpu
- inputs.ntpq
我已经配置了prometheus_client输出插件以将数据发送到prometheus
I've configured to the prometheus_client output plugin to send data to prometheus
这是我的配置:
[[outputs.prometheus_client]]
## Address to listen on.
listen = ":9126"
## Use HTTP Basic Authentication.
# basic_username = "Foo"
# basic_password = "Bar"
## If set, the IP Ranges which are allowed to access metrics.
## ex: ip_range = ["192.168.0.0/24", "192.168.1.0/30"]
# ip_range = []
## Path to publish the metrics on.
path = "/metrics"
## Expiration interval for each metric. 0 == no expiration
#expiration_interval = "0s"
## Collectors to enable, valid entries are "gocollector" and "process".
## If unset, both are enabled.
# collectors_exclude = ["gocollector", "process"]
## Send string metrics as Prometheus labels.
## Unless set to false all string metrics will be sent as labels.
# string_as_label = true
## If set, enable TLS with the given certificate.
# tls_cert = "/etc/ssl/telegraf.crt"
# tls_key = "/etc/ssl/telegraf.key"
## Export metric collection time.
#export_timestamp = true
Here's my prometheus config
# my global config
global:
scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
# scrape_timeout is set to the global default (10s).
# Alertmanager configuration
alerting:
alertmanagers:
- static_configs:
- targets:
# - alertmanager:9093
# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
# - "first_rules.yml"
# - "second_rules.yml"
# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
# The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
- job_name: 'prometheus'
# metrics_path defaults to '/metrics'
# scheme defaults to 'http'.
static_configs:
- targets: ['localhost:9090']
# - job_name: 'node_exporter'
# scrape_interval: 5s
# static_configs:
# - targets: ['localhost:9100']
- job_name: 'telegraf'
scrape_interval: 5s
static_configs:
- targets: ['localhost:9126']
如果我要去http://localhost:9090/metrics，我看不到来自telegraf的任何指标.
If i'm going to http://localhost:9090/metrics i don't see any metrics which are coming from telegraf.
我也从telegraf捕获了一些日志
I've captured some logs from telegraf as well
/opt telegraf --config /etc/telegraf/telegraf.conf --input-filter filestat --test

我在日志中没有看到问题.
I don't see an issue in the logs.
推荐答案
Prometheus服务器的/metrics端点将导出有关服务器本身的指标，而不是从诸如telgraf导出程序之类的目标中刮取的指标.
The /metrics endpoint of your Prometheus server exports metrics about the server itself, not metrics that it scraped from targets like the telgraf exporter.
转到http://localhost:9090/targets，您应该看到Prometheus服务器正在抓取的目标列表.如果配置正确，则Telegraf导出程序应该是其中之一.
Go to http://localhost:9090/targets, you should see a list of targets that your Prometheus server is scraping. If configured correctly, the telegraf exporter should be one of them.
要查询Prometheus以获取Telegraf Exporter生成的指标，请在浏览器中导航到http://localhost:9090/graph，然后输入例如在查询字段中输入cpu_time_user.如果启用了CPU插件，则应该具有该指标和更多指标.
To query Prometheus for telegraf exporter generated metrics, navigate your browser to http://localhost:9090/graph and enter e.g. cpu_time_user in the query field. If the CPU plugin is enabled it should have that and more metrics.
