CoreMonitor
Easily monitor your system's resource usage using our powerful replacement for the default Logitech G15/G19 resource monitor widget.
Features
Graphed CPU Usage
CoreMonitor keeps track of each of your processor's cores, logging their individual load at set intervals. It then generates up to the second graphs showing usage over the past few seconds - allowing you to keep track of what your CPU is really doing.
View Volume Level
Adjusting your system volume can be a pain, especially when you're not sure whether it's the current song or your volume level that's causing the problem. CoreMonitor displays a handy volume bar whenever you adjust your volume, allowing you the get the right volume first time, every time.
Tweak Options
Everybody likes their information a little different, whether you'd prefer to get slower updates but see more historical load information, or want the very latest processor load info - CoreMonitor allows you to choose.
Notification API
CoreMonitor allows applications without their own Logitech G19 integration to easily display notifications using either a basic HTTP API, or by sending structured XML.
API Documentation

GET /system/version
This returns the current CoreMonitor version running on the local system.

GET /notifications/show{?title,text,displayperiod}
This will show a notification on your G15/G19 display with the provided title and text for the given display period.
title- Specifies the title to be displayed on the notification. Should be less than 20 characters long to prevent clipping.text- Specifies the text to be displayed on the notification. Should be less than 200 characters long to prevent clipping.displayperiod- Specifies the amount of time in milliseconds for which the notification should be displayed. If the value0is used, then the notification will remain on the display until the user closes it by pressing the OK button.

tip
This will show a notification for 10 seconds, after which time the notification will disappear. If you would like to hide it prematurely, you can press either the Back or OK button.
NOTE: This requires CoreMonitor to be running on your machine to work
POST /notifications/show
This method allows you to show a notification with a custom icon. To trigger the notification you submit a POST request to the http://localhost:56302/notifications/show endpoint with an XML Message payload.
POST /notifications/show HTTP/1.1
Host: localhost:56302
Content-Type: text/xml
<?xml version="1.0" encoding="utf-8" ?>
<Message>
<type>Notification</type>
<title>Title</title>
<text>Text</text>
<image>Base64 Image</image>
<displayperiod>1000</displayperiod>
</Message>
<!--EOM-->
If you are providing a custom icon, you should serialize a JPG or PNG format image using Base64 encoding. The image itself should be 48x48 pixels in size for best results and using an image will reduce the amount of screen space available for text.
tip
The <!--EOM--> component is used to allow multiple notifications to be pushed through the same socket very quickly without the risk of malformed XML being received by the client. It is not strictly necessary, especially on newer versions of CoreMonitor, however it is recommended that you keep it to support legacy versions which may encounter problems otherwise.
Responses
CoreMonitor will respond with either success or failed depending on whether or not the given parameters were valid. If you attempt to access an unknown path (which would usually result in a 404 error) you will be shown an embedded webpage which details how to use the API.
