While Photoshop is well-known as a photo editor, most people probably don't realize that it also includes some powerful video editing features, as well.In this tutorial, we will show you how to use Photoshop's Timeline Panel to animate Type layers. is periodically getting data from program of files.If the program is not answering or if the file is empty, the value is unknown.This unknown value will be drawn as a zero in graphs.If, as in the upper example, the program reading the sensor is giving reliable values, it is advised to create a script writing the temperature result into a file and to configure RPi-Monitor to read this file.In this case, if the file is not updated, the previous value will be read and drawn in graphs. RPi-Monitor embedded web server is optimized to reduce the usage of the SDCard, reduce the resources used into the system.
You should find the command to execute or the file to read to get the missing value directly in the shell.Once the command is found you will need to update the configuration file.To do so, you should create one configuration file per node to monitor and use all of them in RPi-Monitor. You can use the main page to display some consolidate data in addition to one page per cluster.With system that supports fork (UNIX for example), mrtg can fork itself into multiple instances while it is acquiring data via snmp.
For situations with high latency or a great number of devices this will speed things up considerably.
It will not make things faster, though, if you query a single switch sitting next door.
