This is a great plugin which will help you keep track and brag about the progress you make as you start losing weight or getting healthy. 
You get to decide which measurements you want to keep track of and you can change them at any point.

Health Progress

Health Progress will add a widget and shortcode to your site which will display your starting measurements and progress as you get healthy.

WP Server Health Stats plugin will give you the ability to monitor your WordPress site at its core level. With all-important server health stats like allocated PHP memory, memory usage, realtime RAM usage, CPU usage etc. you can always identify if something wrong is going on with your site.
Now you don’t have to contact your host every single time for minor things. You can easily see the server health stats in your WP admin dashboard and make critical decisions based on that, like if enabling some plugin is consuming a lot of memory or CPU etc.
Please Note: This plugin uses 3rd party systems <a href="http://ip-api.com/" rel="nofollow ugc">ip-api.com</a> to get the location details for the server IP. Please check their <a href="https://www.ip-api.com/docs/legal" rel="nofollow ugc">Privacy Policy and Terms</a>. By default the plugin uses the free version of IP-API service but if you have purchased a premium version then you can enter your API key inside the plugin settings page.

<h3>Q: After installing this plugin my server load has increased tremendously. How to fix this?</h3>
<blockquote>
This plugin uses Ajax to call the server after an interval of time to get the latest data about the server, giving you the real-time update. By default, this happens after every 200ms. But if you are using a low-end server with fewer resources, calling the server after each 200ms can increase your server load drastically. You can easily solve this too. On the left-hand side menu of WP Admin panel, you will see a settings panel for WP Server Stats under that you will find another sub-menu called General Settings. Within general settings, the first option is to change the interval time. Change it to how much higher your want like 2000ms (2 sec) or maybe 20000ms (20 sec) depending on your need. Once you save the settings the plugin will call the server only after the interval you have set, reducing your server load back to how it was without this plugin.
</blockquote>
But again, generally speaking, if you are in a decent to good hosting, you won’t face this problem at all, as this a very lightweight plugin.

READ BEFORE INSTALLING
This plugin uses PHP <code>shell_exec()</code> function which is by default enabled by all good hosting companies. But a small percentage of hosting company disable <code>shell_exec()</code> by default. So, please contact your hosting company to make sure <code>shell_exec()</code> is enabled in your account before installing this plugin. Otherwise, you will get an ERROR Code <code>EXEC096T</code> for every feature that uses <code>shell_exec()</code>.
<blockquote>
Now this plugin is also hosted in <a href="https://github.com/isaumya/wp-server-stats" rel="nofollow ugc">Github</a>. But the Github repo will be used for the development of the plugin. So, from now on you can also report the bugs in <a href="https://github.com/isaumya/wp-server-stats/issues" rel="nofollow ugc">Github Issue Tracker</a> if you want.

Very Important Note
This plugin has been developed and tested on Linux based servers only so there is a very high chance that it might NOT work for Windows-based servers. So, I highly recommend this plugin to be used by those users who use a Linux based server. 
I currently have no plan to add Windows Server support as a very tiny amount of people still use Windows Server in this Linux age. I may add Windows support in future.
ERROR Code List
EXEC096T – PHP <code>shell_exec()</code> function has not been enabled in your account, which this plugin needs to run properly. Contact your server host and ask them to enable PHP <code>shell_exec()</code> function for your account.
IP096T – Your server is not returning the IP properly. There is definitely some issue with your server configuration. Please contact your host and tell them that PHP <code>gethostbyname( gethostname() )</code> is unable to get the server IP, ask them to look into their server configuration and to fix the configuration issue. If you have a self-hosted VPS or dedicated server, the reason is still the same. If you are unable to find the configuration issue inside your server, I highly suggest you hire a knowledgeable server admin to look into your server. In most cases, you should never get this error message.
Languages
WP Server Stats is 100% compatible with translation and you can translate any text to whatever language you want. As this plugin doesn’t come with an inbuilt translation, I will suggest you to use a plugin like <a href="https://wordpress.org/plugins/say-what/" rel="ugc">Say What?</a> to change the text, you just have to use the text domain as <code>wp-server-stats</code> within the plugin to change the text.
Very Special Thanks
The list of people whom I especially want to thank without whom this plugin would have never been completed.

WP Server Health Stats

I think adding a chart to see usage over time would be a very useful addition to help diagnose events that happened in the past.

chart over time

Monitor your WP site the right way with most important stats like Database, PHP details, PHP Memory, RAM Usage, CPU load, Server Uptime & more.
