Kafka学习之四_Grafana监控相关的学习
背景
想一并学习一下kafaka的监控.
又重新开始学习grafana了:
下载地址:
https://grafana.com/grafana/download
https://prometheus.io/download/
https://github.com/danielqsj/kafka_exporter
利用这三个网站下载较新的资源,然后进行测试与安装使用.
之前写过很多rpm还有docker的方式方法,想着这次使用一下二进制方式安装.
在某些机器上面可能更加方便一点
这次主要是想在 鲲鹏上面验证, 所以下载的文件如下:
alertmanager-0.25.0.linux-arm64.tar.gz
grafana-enterprise-10.0.1.linux-arm64.tar.gz
kafka_exporter-1.7.0.linux-arm64.tar.gz
prometheus-2.44.0.linux-arm64.tar.gz
安装-grafana
解压缩 grafana的压缩包
然后查看部分命令的帮助信息
./grafana server -h
NAME:
grafana server - run the grafana server
USAGE:
grafana server [command options] [arguments...]
OPTIONS:
--config value Path to config file
--homepath value Path to Grafana install/home path, defaults to working directory
--pidfile value Path to Grafana pid file
--packaging value describes the way Grafana was installed (default: "unknown")
--configOverrides value Configuration options to override defaults as a string. e.g. cfg:default.paths.log=/dev/null
--version, -v print the version
--vv prints current version, all dependencies and exits (default: false)
--profile Turn on pprof profiling (default: false)
--profile-addr value Define custom address for profiling (default: "localhost")
--profile-port value Define custom port for profiling (default: 6060)
--tracing Turn on tracing (default: false)
--tracing-file value Define tracing output file (default: "trace.out")
--help, -h show help
最简单的启动脚本为
cd /grafana-xx-xx/bin
nohup ./grafana server --config ../conf/defaults.ini 2>&1 >/devnull &
注意可以修改 ../conf/defaults.ini 内的文件制定很多配置.
默认密码是 admin/admin 第一次登录需要修改密码
安装kafka-exporter
启动脚本为:
nohup ./kafka_exporter --sasl.enabled --web.listen-address=":9308" --sasl.username="admin" --sasl.password="Test20131127" --sasl.mechanism="plain" --kafka.server=127.0.0.1:9093 2>&1 >/devnull &
解压缩先查看帮助然后根据帮助进行处理
Flags:
-h, --[no-]help Show context-sensitive help (also try --help-long and --help-man).
--web.listen-address=":9308"
Address to listen on for web interface and telemetry.
--web.telemetry-path="/metrics"
Path under which to expose metrics.
--topic.filter=".*" Regex that determines which topics to collect.
--topic.exclude="^$" Regex that determines which topics to exclude.
--group.filter=".*" Regex that determines which consumer groups to collect.
--group.exclude="^$" Regex that determines which consumer groups to exclude.
--[no-]log.enable-sarama Turn on Sarama logging, default is false.
--kafka.server=kafka:9092 ...
Address (host:port) of Kafka server.
--[no-]sasl.enabled Connect using SASL/PLAIN, default is false.
--[no-]sasl.handshake Only set this to false if using a non-Kafka SASL proxy, default is true.
--sasl.username="" SASL user name.
--sasl.password="" SASL user password.

Configure the Kerberos client to not use PA_FX_FAST, default is false.
--[no-]tls.enabled Connect to Kafka using TLS, default is false.
--tls.server-name="" Used to verify the hostname on the returned certificates unless tls.insecure-skip-tls-verify is given. The kafka server's name
should be given.
--tls.ca-file="" The optional certificate authority file for Kafka TLS client authentication.
--tls.cert-file="" The optional certificate file for Kafka client authentication.
--tls.key-file="" The optional key file for Kafka client authentication.
--[no-]server.tls.enabled Enable TLS for web server, default is false.
--[no-]server.tls.mutual-auth-enabled
Enable TLS client mutual authentication, default is false.
--server.tls.ca-file="" The certificate authority file for the web server.
--server.tls.cert-file="" The certificate file for the web server.
--server.tls.key-file="" The key file for the web server.
--[no-]tls.insecure-skip-tls-verify
If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure. Default is

--kafka.version="2.0.0" Kafka broker version
--[no-]use.consumelag.zookeeper
if you need to use a group from zookeeper, default is false
--zookeeper.server=localhost:2181 ...

--log.level=info Only log messages with the given severity or above. One of: [debug, info, warn, error]
--log.format=logfmt Output format of log messages. One of: [logfmt, json]
--[no-]version Show application version.
安装以及监控kafaka-prometheus
1. prometheus的日志留存时间和大小限制
--storage.tsdb.retention.time=15d
其实默认值就是 15天, 可以根据情况适当进行调整.
2. 存放目录
--storage.tsdb.path="/prometheusdata/"
3.大小
--storage.tsdb.retention.size=15GB
4. 修改端口
--web.listen-address="0.0.0.0:9095"
5. 设置监控kafka
scrape_configs:
# 监控业务kafka
- job_name: 'kafka'
static_configs:
- targets:
- 127.0.0.1:9308
整体命令为:
nohup ./prometheus --storage.tsdb.retention.time=15d --storage.tsdb.path="/prometheusdata/" --storage.tsdb.retention.size=15GB --web.listen-address="0.0.0.0:9095" 2>&1 >/dev/null &
增加数据源
增加prometheus的数据源
然后grafana导入: 7589 监控就可以了.
结果展示
