Grafana

简介

Grafana 是一款开源的数据可视化工具，使用 Grafana 可以非常轻松的将数据转成图表(如下图)的展现形式来做到数据监控以及数据统计。

下载软件包

wget https://dl.grafana.com/enterprise/release/grafana-enterprise-9.1.6.linux-amd64.tar.gz

安装部署

解压

tar -xvzf grafana-enterprise-9.1.6.linux-arm64.tar.gz

mv grafana-9.1.6 /data/apps/
cd /data/apps/grafana-9.1.6/conf
cp sample.ini grafana.ini

修改配置文件

vim grafana.ini

[paths]
# Path to where grafana can store temp files, sessions, and the sqlite3 db (if that is used)
;data = /var/lib/grafana
data = /data/apps/grafana-9.1.6/data
logs = /data/apps/grafana-9.1.6/logs
plugins = /data/apps/grafana-9.1.6/plugins

[log]

mode = file
level = warn

创建用户

groupadd -g 9100 monitor
useradd -g 9100 -u 9100 -s /sbin/nologin -M monitor
mkdir data && mkdir logs && mkdir plugins

chown -R monitor:monitor grafana-9.1.6

创建Systemd服务

vim /usr/lib/systemd/system/grafana.service

[Unit]
Description=grafana service
After=network.target

[Service]
User=monitor
Group=monitor
KillMode=control-group
Restart=on-failure
RestartSec=60
ExecStart=/data/apps/grafana-9.1.6/bin/grafana-server -config /data/apps/grafana-9.1.6/conf/grafana.ini -pidfile /data/apps/grafana-9.1.6/grafana.pid -homepath /data/apps/grafana-9.1.6

[Install]
WantedBy=multi-user.target

启动 Grafana

systemctl daemon-reload
systemctl restart grafana.service
systemctl enable grafana.service
systemctl status grafana

Spark应用监控 Graphite_exporter

配置 mapping 文件

cd /usr/local/graphite_exporter
vim graphite_exporter_mapping

graphite_exportergraphite_exportengs:
- match: '*.*.executor.filesystem.*.*'
  name: spark_app_filesystem_usage
  labels:
    application: $1
    executor_id: $2
    fs_type: $3
    qty: $4

修改spark的metrics.properties配置文件，让其推送metrics到Graphite_exporter

*.sink.graphite.class=org.apache.spark.metrics.sink.GraphiteSink
*.sink.graphite.host=10.253.128.31
*.sink.graphite.port=9108
*.sink.graphite.period=10
*.sink.graphite.unit=seconds
#*.sink.graphite.prefix=<optional_value>
