kubernetes-基于Prometheus和Grafana监控rabbitmq(rabbitmq-exporter)

1、安装和配置rabbitmq-exporter

1.1 使用helm安装rabbitmq-exporter

这里的rabbitmq-exporter通过helm在Kubernetes中进行安装,这里需要通过rabbitmq.url,rabbitmq.user和rabbitmq.password,设置正确的rabbitmq的url地址和用户/密码。

$ helm install prom-rabbit stable/prometheus-rabbitmq-exporter --set "rabbitmq.url=http://rabbit-service:15672" 
/ --set "rabbitmq.user=user" --s set "rabbitmq.password=bitnami" --namespace=kube-public

rabbitmq-exporter具体配置信息请参考下表:

Parameter Description Default
replicaCount desired number of prometheus-rabbitmq-exporter pods 1
image.repository prometheus-rabbitmq-exporter image repository kbudde/rabbitmq-exporter
image.tag prometheus-rabbitmq-exporter image tag v0.29.0
image.pullPolicy image pull policy IfNotPresent
service.type desired service type ClusterIP
service.internalport service listening port 9419
service.externalPort public service port 9419
resources cpu/memory resource requests/limits {}
loglevel exporter log level {}
rabbitmq.url rabbitmq management url http://myrabbit:15672
rabbitmq.user rabbitmq user login guest
rabbitmq.password rabbitmq password login guest
rabbitmq.existingPasswordSecret existing secret name containing password key ~
rabbitmq.capabilities comma-separated list of capabilities supported by the RabbitMQ server bert,no_sort
rabbitmq.include_queues regex queue filter. just matching names are exported .*
rabbitmq.skip_queues regex, matching queue names are not exported ^$
rabbitmq.include_vhost regex vhost filter. Only queues in matching vhosts are exported .*
rabbitmq.skip_vhost regex, matching vhost names are not exported. First performs include_vhost, then skip_vhost ^$
rabbitmq.skip_verify true/0 will ignore certificate errors of the management plugin false
rabbitmq.exporters List of enabled modules. Just “connections” is not enabled by default exchange,node,overview,queue
rabbitmq.output_format Log ouput format. TTY and JSON are suported TTY
rabbitmq.timeout timeout in seconds for retrieving data from management plugin 30
rabbitmq.max_queues max number of queues before we drop metrics (disabled if set to 0) 0
annotations pod annotations for easier discovery {}
prometheus.monitor.enabled Set this to true to create ServiceMonitor for Prometheus operator false
prometheus.monitor.additionalLabels Additional labels that can be used so ServiceMonitor will be discovered by Prometheus {}
prometheus.monitor.interval Interval at which Prometheus Operator scrapes exporter 15s
prometheus.monitor.namespace Selector to select which namespaces the Endpoints objects are discovered from. []

1.2 查看rabbitmq指标数据

在浏览器中访问rabbitmq-exporter,能够看到所要监控的指标。

 

2、Prometheus监控

2.1 配置Prometheus

在Prometheus的配置文件(Prometheus.yaml)中,添加红色字体部分的内容。

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’]

# 配置从redis-exporter中获取数据,目标地址为:10.0.32.148:9182

 – job_name: ‘rabbit’
static_configs:
– targets: [‘prom-rabbit-prometheus-rabbitmq-exporter:9419’]

2.2 配置验证

在浏览器的地址栏访问http://{prometheus}/targets,将会看到新配置的rabbitmq。

 

3 Grafana监控

3.1 配置Windows监控dashboard

下载rabbitmq-exporter的dashboard(rabbitmq-monitoring_rev4.json),下载地址:https://grafana.com/grafana/dashboards/4279

 

在grafana中导入dashboard:rabbitmq-monitoring_rev4.json。

 

导入后,通过此dashborad,管理员就可以监控rabbitmq的运行状态、内存、磁盘空间、消息队列和消息状态等指标。
