但是，遇到很重要的tidb监控看板，如果删除了数据，很多东西都没有了，那么有没有一种好的方法呢？

starsnode（ps：打个包贼拉麻烦，ai帮忙写了贼多代码）简介源码[starsnode]是一个系统状态监控软件。展示的信息包括：cpu、内存、硬盘、网速、网卡等信息。

可以在某些动作前后增加处理，实现监控。

就类似于监控那种，谢谢！

硬件监控工具或传感器：一些特定的硬件，如笔记本电脑，主板可能会集成有电源管理芯片，并可通过诸如lm-sensors这样的工具读取温度、电压以及风扇转速等数据，但不是所有硬件都支持功耗监测。

-监控与优化：持续监控模型在实际环境中的表现，并根据反馈进行调整或再训练。

，比如获取所有歌曲，/song/getAll(这是我微服务的其中一个接口，得根据实际的接口来)，一段时间没有流量了，实时监控的数据也就会清空，但是簇点链路会存在的2、Sentinel的异常处理BlockException

由于较多的监控面板需要查看，为了便于巡检，需要使用nginx把grafan和prometheus的url代理出来。

前情提要在之前，我编写了一个系统状态监控软件:starsnode.但是，最近一段时间，qt客户端在win环境下通通失联掉线了。软件都是之前打包的，没有修改过任何依赖。

定期检查并维护索引，删除不再被使用的索引，监控重复和冗余索引。注意索引的选择性，即唯一值越多的列越适合做索引。避免全表扫描：避免在没有适当索引的情况下执行全表扫描，尤其是在大表上。

如下图所示：看着这图CPU资源也不是特别高啊，但是结合整体的资源监控来看，不仅仅是CPU飙升，还有内网带宽、公网带宽、磁盘读写、内存基本上是同时飙高，然后我就有点慌，是不是中了什么病毒。

缘起在界面跳转过程中，我们常常需要传递一些参数，例如埋点参数等可能需要一直向下传递的信息。然而，当界面跳转层级较深时，很容易出现中途忘记传递参数的情况。此时，如何高效排查参数传递问题就成为了一个关键需求。基于此，我想到可以开发一个工具类，实现界面跳转时参数的自动打印，以便于快速定位和解决参数传递过程中出现的问题。缘灭那么，如何具体实现这个工具类呢？熟悉Android开发的同学都知道，系统提供了Application.ActivityLifecycleCallbacks类，我们可以通过context.registerActivityLifecycleCallbacks()方法进行注册。借助该类的回调机制，能够监听到Activity的各个生命周期。我们的目标是在onActivityCreated回调中打印出上一个界面传递过来的参数，因为在这个回调中可以获取到Activity创建时的相关参数信息。以下是ActivityLifecycleCallbacks接口的定义publicinterfaceActivityLifecycleCallbacks{/***CalledasthefirststepoftheActivitybeingcreated.Thisisalwayscalledbefore*{@linkActivity#onCreate}.*/defaultvoidonActivityPreCreated(@NonNullActivityactivity,@NullableBundlesavedInstanceState){}/***CalledwhentheActivitycalls{@linkActivity#onCreatesuper.onCreate()}.*/voidonActivityCreated(@NonNullActivityactivity,@NullableBundlesavedInstanceState);/***CalledasthelaststepoftheActivitybeingcreated.Thisisalwayscalledafter*{@linkActivity#onCreate}.*/defaultvoidonActivityPostCreated(@NonNullActivityactivity,@NullableBundlesavedInstanceState){}/***CalledasthefirststepoftheActivitybeingstarted.Thisisalwayscalledbefore*{@linkActivity#onStart}.*/defaultvoidonActivityPreStarted(@NonNullActivityactivity){}/***CalledwhentheActivitycalls{@linkActivity#onStartsuper.onStart()}.*/voidonActivityStarted(@NonNullActivityactivity);/***CalledasthelaststepoftheActivitybeingstarted.Thisisalwayscalledafter*{@linkActivity#onStart}.*/defaultvoidonActivityPostStarted(@NonNullActivityactivity){}/***CalledasthefirststepoftheActivitybeingresumed.Thisisalwayscalledbefore*{@linkActivity#onResume}.*/defaultvoidonActivityPreResumed(@NonNullActivityactivity){}/***CalledwhentheActivitycalls{@linkActivity#onResumesuper.onResume()}.*/voidonActivityResumed(@NonNullActivityactivity);/***CalledasthelaststepoftheActivitybeingresumed.Thisisalwayscalledafter*{@linkActivity#onResume}and{@linkActivity#onPostResume}.*/defaultvoidonActivityPostResumed(@NonNullActivityactivity){}/***CalledasthefirststepoftheActivitybeingpaused.Thisisalwayscalledbefore*{@linkActivity#onPause}.*/defaultvoidonActivityPrePaused(@NonNullActivityactivity){}/***CalledwhentheActivitycalls{@linkActivity#onPausesuper.onPause()}.*/voidonActivityPaused(@NonNullActivityactivity);/***CalledasthelaststepoftheActivitybeingpaused.Thisisalwayscalledafter*{@linkActivity#onPause}.*/defaultvoidonActivityPostPaused(@NonNullActivityactivity){}/***CalledasthefirststepoftheActivitybeingstopped.Thisisalwayscalledbefore*{@linkActivity#onStop}.*/defaultvoidonActivityPreStopped(@NonNullActivityactivity){}/***CalledwhentheActivitycalls{@linkActivity#onStopsuper.onStop()}.*/voidonActivityStopped(@NonNullActivityactivity);/***CalledasthelaststepoftheActivitybeingstopped.Thisisalwayscalledafter*{@linkActivity#onStop}.*/defaultvoidonActivityPostStopped(@NonNullActivityactivity){}/***CalledasthefirststepoftheActivitysavingitsinstancestate.Thisisalways*calledbefore{@linkActivity#onSaveInstanceState}.*/defaultvoidonActivityPreSaveInstanceState(@NonNullActivityactivity,@NonNullBundleoutState){}/***CalledwhentheActivitycalls*{@linkActivity#onSaveInstanceStatesuper.onSaveInstanceState()}.*/voidonActivitySaveInstanceState(@NonNullActivityactivity,@NonNullBundleoutState);/***CalledasthelaststepoftheActivitysavingitsinstancestate.Thisisalways*calledafter{@linkActivity#onSaveInstanceState}.*/defaultvoidonActivityPostSaveInstanceState(@NonNullActivityactivity,@NonNullBundleoutState){}/***CalledasthefirststepoftheActivitybeingdestroyed.Thisisalwayscalledbefore*{@linkActivity#onDestroy}.*/defaultvoidonActivityPreDestroyed(@NonNullActivityactivity){}/***CalledwhentheActivitycalls{@linkActivity#onDestroysuper.onDestroy()}.*/voidonActivityDestroyed(@NonNullActivityactivity);/***CalledasthelaststepoftheActivitybeingdestroyed.Thisisalwayscalledafter*{@linkActivity#onDestroy}.*/defaultvoidonActivityPostDestroyed(@NonNullActivityactivity){}/***CalledwhentheActivityconfigurationwaschanged.*@hide*/defaultvoidonActivityConfigurationChanged(@NonNullActivityactivity){}}通过上述接口，我们可以在合适的生命周期回调中获取Activity的Bundle参数。由于Bundle内部维护了一个mMap参数，因此可以通过遍历的方式获取所有的key，并根据key获取对应的value进行打印。importandroid.app.Activityimportandroid.app.Applicationimportandroid.content.Intentimportandroid.os.Bundleimportcom.blankj.utilcode.util.LogUtilsimportorg.json.JSONExceptionimportorg.json.JSONObjectclassActivityLifecycleLogger:Application.ActivityLifecycleCallbacks{overridefunonActivityCreated(activity:Activity,savedInstanceState:Bundle?){LogUtils.d("onActivityCreated：===>exe...",activity,convertToJson(activity.intent))}privatefunconvertToJson(intent:Intent):String{returnintent.extras?.let{convertToJson(it)}?:JSONObject().toString()}privatefunconvertToJson(bundle:Bundle):String{valjsonObject=JSONObject()for(keyinbundle.keySet()){try{jsonObject.put(key,bundle[key])}catch(e:JSONException){e.printStackTrace()}}returnjsonObject.toString()}overridefunonActivityStarted(activity:Activity){}overridefunonActivityResumed(activity:Activity){}overridefunonActivityPaused(activity:Activity){}overridefunonAct
