安裝過程記錄
解壓縮包重命名目錄
mkdir /opt/software
tar xf kafka-eagle-bin-1.3.8.tar.gz -C /opt/software/
cd /opt/software/kafka-eagle-bin-1.3.8
tar xf kafka-eagle-web-1.3.8-bin.tar.gz
mv kafka-eagle-web-1.3.8 kafka-eagle
配置環(huán)境變量
- 設(shè)置Kafka-Eagle目錄
vim /etc/profile
export KE_HOME= /opt/software/kafka-eagle
PATH=$PATH:$KE_HOME/bin
- 設(shè)置java目錄
vim /etc/profile
export JAVA_HOME= /usr/local/java/
更新環(huán)境變量
source /etc/profile
修改Kafka-Eagle配置文件
cd kafka-eagle/conf
vim system-config.properties

啟動kafka-eagle
cd ../bin/
chmod +x ke.sh
./ke.sh start
啟動成功打印日志如下;

監(jiān)控趨勢圖
Kafka系統(tǒng)默認是沒有開啟JMX端口的考廉，所以Kafka Eagle的監(jiān)控趨勢圖默認采用不啟用的方式，即kafka.eagle.metrics.charts=false携御。如果需要查看監(jiān)控趨勢圖昌粤，需要開啟Kafka系統(tǒng)的JMX端口，設(shè)置該端口在$KAFKA_HOME/bin/kafka-server-start.sh腳本中啄刹，設(shè)置內(nèi)容如下：
vim /opt/software/kafka-eagle/conf/system-config.properties
######################################
# enable kafka metrics
######################################
kafka.eagle.metrics.charts=true
kafka.eagle.sql.fix.error=true
vi /opt/software/kafka/bin/kafka-server-start.sh
if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then
export KAFKA_HEAP_OPTS="-server -Xms2G -Xmx2G -XX:PermSize=128m -XX:+UseG1GC -XX:MaxGCPauseMillis=200 -XX:ParallelGCThreads=8 -XX:ConcGCThreads=5 -XX:InitiatingHeapOccupancyPercent=70"
# 這里的端口不一定非要設(shè)置成9999涮坐，端口只要可用，均可誓军。
export JMX_PORT="9999"
#export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G"
fi
Kafka Eagle系統(tǒng)會自動獲取這個JMX端口袱讹，采集結(jié)果如下：
