WP-Memory-Usage is a lightweight but powerful WordPress plugin that monitors and displays memory usage directly in your WordPress admin area. 
This tool is essential for site administrators and developers who need to keep an eye on the memory consumption of their WordPress installation, helping to identify potential issues and optimize performance.
What the plugin shows:
In the admin footer (every admin page): 
* Current memory usage vs. WordPress limit (with percentage) 
* Current memory usage vs. PHP limit (with percentage) 
* Server IP address and server name 
* PHP version
In the Dashboard widget (“Memory Overview”): 
* PHP version, architecture (32/64 bit), max execution time 
* WordPress memory limit (WP_MEMORY_LIMIT), WordPress admin limit (WP_MAX_MEMORY_LIMIT), PHP memory limit 
* Current peak memory usage with a visual progress bar (colour-coded: green / orange / red) 
* Link to the Threshold Alerts settings page
Memory Alerts Tabs (since 2.0.0): 
Log events, set thresholds (Warning / Danger / Critical), monitor memory usage…
<h3>Why Use WP-Memory-Usage?</h3>
Excessive memory usage leads to slower sites, HTTP 500 errors, and failed background jobs (cron, imports, backups). WP-Memory-Usage gives you the information you need to act before users are affected — without overwhelming you with notifications.

Kyght

Tracks the distribution of your installable products. The plugin provides an ajax API to accept installation registrations & usage data. Also provides a mechanism for pushing product upgrades to clients. Custom build tags can also be used to track clients with customized products and push custom upgrades to these clients.
Plugin REST API 
 http://www.yoursite.com/wp-admin/admin-ajax.php
<pre><code>Actions:
 regupdate - Adds\Updates a registration record
 useapp - Updates product\version usage and registered client use
 upgrade - Checks for a product upgrade with a higher version number

Note: Product and Registration records are automatically added\updated via inbound API calls. Only Upgrades are added via the Admin console.

Example (.Net API call to register a client)

 **Registration**
 var response = HttpHelper.Post(URL, new NameValueCollection() {
 { "action", "regupdate" }, 
 { "sky", SecretKey }, //Secret ID must match ID in your WordPress|Settings|InstallTracker 
 { "product", Product },
 { "ver", Version },
 { "custom", Custom },

 { "trackid", RegID }, //TrackID from previous registration to allow updates, blank for new
 { "key", key }, //GUID generated by your installation (Format: 00000000-0000-0000-0000-000000000000 )
 { "name", name },
 { "email", email },
 { "phone", phone },
 { "contact", contact },
 { "addr", address },
 { "city", city },
 { "state", state },
 { "zipcode", zipcode}
 }); 

 var str = System.Text.Encoding.Default.GetString(response);
 if (str != null && str.Equals("0")) return false; //Secret key might not match
 var outObject = JsonConvert.DeserializeObject<Registration>(str);
 if (outObject.valid == "TRUE")
 {
 RegID = outObject.regID; //Returned Registration ID for future updates
 return true;
 } 

 **Usage**
 var pars = new NameValueCollection() {
 { "action", "useapp" }, 
 { "sky", SecretKey }, 
 { "product", Product },
 { "ver", Version },
 { "custom", Custom },

 { "trackid", RegID }, //TrackID from previous registration (optional)
 { "key", key } //GUID generated by your installation (optional)
 };


 **Upgrade**
 var pars = new NameValueCollection() {
 { "action", "upgrade" }, 
 { "sky", SecretKey }, 
 { "product", Product },
 { "ver", Version },
 { "custom", Custom },
 };
