Do you need JMX for Go?

<p><a href="https://en.wikipedia.org/wiki/Java_Management_Extensions" rel="nofollow">https://en.wikipedia.org/wiki/Java_Management_Extensions</a></p> <p>There is a less maintained lib, but it only provides read capability. <a href="https://github.com/davecheney/gmx" rel="nofollow">https://github.com/davecheney/gmx</a></p> <hr/>**评论：**<br/><br/>tv64738: <pre><p>Let&#39;s not call the concept of exporting metrics &#34;JMX&#34;.</p> <p>Also, might as well make it a Prometheus exporter.</p></pre>tex0: <pre><p>JMX is much more than metrics. But sure what OP is trying to say.</p></pre>wanghq: <pre><p>Exactly. I find that somehow I need two way communication, e.g. enable the detailed debugging on this host for a minute. AFAIK, Prometheus is not capable of &#34;Consulting and changing application configuration&#34; </p> <p><a href="https://docs.oracle.com/javase/8/docs/technotes/guides/jmx/index.html" rel="nofollow">https://docs.oracle.com/javase/8/docs/technotes/guides/jmx/index.html</a></p> <blockquote> <p>Typical uses of the JMX technology include: 1. Consulting and changing application configuration 2. Accumulating statistics about application behavior and making them available 3. Notifying of state changes and erroneous conditions.</p> </blockquote></pre>tv64738: <pre><p>Perhaps, but gmx ain&#39;t.</p></pre>titpetric: <pre><p>You can export pprof data to prometheus, so everything you need is already there, you just need to enable it. In fact Prometheus profiles itself with pprof, since it&#39;s written in Go.</p></pre>tex0: <pre><p>As far as I know the Prometheus Go client makes no use of pprof.</p></pre>Redundancy_: <pre><p>Have you looked at something like <a href="https://stackimpact.com/" rel="nofollow">https://stackimpact.com/</a> ?</p></pre>hollafi: <pre><p>Maybe check out expvar.</p></pre>hobbified: <pre><p>Do you need it for Java? Not as far as I can tell.</p></pre>wanghq: <pre><p>Sorry for the ambiguous description. I need a JMX like thing which works for Go so I can view and change my application stats.</p></pre>hobbified: <pre><p>Yes, and my point was that it&#39;s a lousy idea in Java, which makes it twice as lousy an idea in Go, because it doesn&#39;t even have the peer-pressure excuse. For viewing, you might want to use expvar, which is in the core and has integrations with some things. For changing configs... no, don&#39;t just casually do that. Don&#39;t even think about using a thing that makes it easy :)</p></pre>
