无法在Windows 10上为Cassandra运行prometheus

问题描述

我正在按照本教程在 Windows10 上运行 Prometheus .本教程适用于 linux .我想我唯一需要更改的命令是 powershell .但是，当我尝试访问指标时，应用程序无法连接.

I am following this tutorial to run Prometheus on Windows10. The tutorial is for linux. I suppose the only command I need to change is for powershell. However, when I try to access the metrics, the application doesn't connect.

代替 echo'JVM_OPTS =''$ JVM_OPTS -javaagent:'$ PWD/jmx_prometheus_javaagent-0.3.0.jar = 7070:$ PWD/cassandra.yml'''>>conf/cassandra-env.sh ，我在 cassandra-env.ps1

    # Default JMX setup, bound to local loopback address only
    $env:JVM_OPTS="$env:JVM_OPTS -Dcassandra.jmx.local.port=$JMX_PORT"
    $env:JVM_OPTS="$env:JVM_OPTS -javaagent:'$PWD/jmx_prometheus_javaagent-0.3.0.jar=7070:$PWD/cassandra.yml'"' <-- HERE

    $env:JVM_OPTS="$env:JVM_OPTS $env:JVM_EXTRA_OPTS"
}

但是 http://localhost:7070/metrics 不起作用

更新现在，我从 .sh 中删除了更改.和 ps1 并仅在 bin/cassanbra.bat 文件中添加 javaagent ，因为这似乎是Windows所需的

UPDATENow, I have removed the changes from .sh. and ps1 and add the javaagent only in bin/cassanbra.bat file as it seems that is what is required in Windows

但是现在我得到了错误

推荐答案

代替此:

$env:JVM_OPTS="$env:JVM_OPTS -javaagent:'$PWD/jmx_prometheus_javaagent-0.3.0.jar=7070:$PWD/cassandra.yml'"'

尝试一下:

$env:JVM_OPTS="$env:JVM_OPTS -javaagent:'$PWD/jmx_prometheus_javaagent-0.3.0.jar=7070:$PWD/cassandra.yml'"

我从行尾删除了一个引号.

I removed a single quote from the end of the line.
