我正在使用 JMX 从 Apache Kafka 收集指标并通过 collectd 发送到可视化和监控服务 Librato。问题是某些指标似乎报告错误。例如，在没有任何人使用 Kafka 集群的情况下，一些节点报告每分钟有大量传入消息（如 15,000 条），而其他节点报告为 0，正如预期的那样。
这是 collectd 中的一项指标配置：
<MBean "kafka-all-messages">
ObjectName "kafka.server:type=BrokerTopicMetrics,name=MessagesInPerSec"
InstancePrefix "all"
<Value>
InstancePrefix "kafka-messages-in"
Type "counter"
Table false
Attribute "MeanRate"
</Value>
</MBean>
这是 Librato 中的图表：
有谁知道出了什么问题？是我收集的配置，例如Type或类似的东西吗？
我有一台安装了 Apache Kafka 的 Ubuntu 16.04 机器。start_kafka.sh目前，我可以通过使用具有以下内容的脚本使其完美运行：
JMX_PORT=17264 KAFKA_HEAP_OPTS="-Xms1024M -Xmx3072M" /home/kafka/kafka_2.11-0.10.1.0/bin/kafka-server-start.sh -daemon /home/kafka/kafka_2.11-0.10.1.0/config/server.properties
现在，我想使用supervisor它来自动重启进程，如果它失败并在重启机器后立即启动。问题是我无法supervisor启动 Kafka。
我supervisor使用安装pip并将此配置文件放置在/etc/supervisord.conf：
; Supervisor config file.
;
; For more information on the config file, please see:
; http://supervisord.org/configuration.html
[unix_http_server]
file=/tmp/supervisor.sock ; (the path to the socket file)
[supervisord]
logfile=/tmp/supervisord.log ; (main log file;default $CWD/supervisord.log)
logfile_maxbytes=50MB ; (max main logfile bytes b4 rotation;default 50MB)

; the below section must remain in the config file for RPC
; (supervisorctl/web interface) to work, additional interfaces may be

[supervisorctl]

[program:kafka]
command=/home/kafka/kafka_2.11-0.10.1.0/start_kafka.sh ; the program (relative uses PATH, can take args)
;process_name=%(program_name)s ; process_name expr (default %(program_name)s)
startsecs=10 ; # of secs prog must stay up to be running (def. 1)
startretries=3 ; max # of serial start failures when starting (default 3)
;autorestart=unexpected ; when to restart if exited after running (def: unexpected)
;exitcodes=0,2 ; 'expected' exit codes used with autorestart (default 0,2)
stopsignal=TERM ; signal used to kill process (default TERM)
stopwaitsecs=180 ; max num secs to wait b4 SIGKILL (default 10)
stdout_logfile=NONE ; stdout log path, NONE for none; default AUTO
;environment=A="1",B="2" ; process environment additions (def no adds)
当我尝试启动 Kafka 时，出现以下错误：
# supervisorctl start kafka
kafka: ERROR (spawn error)
主管日志 (at /tmp/supervisord.log) 包含以下内容：
2017-01-23 22:10:24,532 INFO spawned: 'kafka' with pid 21311

2017-01-23 22:10:31,578 INFO gave up: kafka entered FATAL state, too many start retries too quickly
必须说我已经尝试删除-daemon标志start_kafka.sh以使用supervisor但没有成功。
有人知道发生了什么吗？
