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/downloadhttps://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.gzgrafana-enterprise-10.0.1.linux-arm64.tar.gzkafka_exporter-1.7.0.linux-arm64.tar.gzprometheus-2.44.0.linux-arm64.tar.gz
解压缩 grafana的压缩包然后查看部分命令的帮助信息./grafana server -hNAME: grafana server - run the grafana serverUSAGE: 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/binnohup ./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
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. --sasl.mechanism="" The SASL SCRAM SHA algorithm sha256 or sha512 or gssapi as mechanism --sasl.service-name="" Service name when using kerberos Auth --sasl.kerberos-config-path="" Kerberos config path --sasl.realm="" Kerberos realm --sasl.kerberos-auth-type="" Kerberos auth type. Either "keytabAuth" or "userAuth" --sasl.keytab-path="" Kerberos keytab file path --[no-]sasl.disable-PA-FX-FAST 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 false --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 ... Address (hosts) of zookeeper server. --kafka.labels="" Kafka cluster name --refresh.metadata="30s" Metadata refresh interval --[no-]offset.show-all Whether show the offset/lag for all consumer group, otherwise, only show connected consumer groups, default is true --[no-]concurrent.enable If true, all scrapes will trigger kafka operations otherwise, they will share results. WARN: This should be disabled on large clusters. Default is false --topic.workers=100 Number of topic workers --[no-]kafka.allow-auto-topic-creation If true, the broker may auto-create topics that we requested which do not already exist, default is false. --verbosity=0 Verbosity log level --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.
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=15GB4. 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prometheus的数据源然后grafana导入: 7589 监控就可以了.
