Network monitoring

[Digit]

This weekend I upgraded my Domotica application for the 1st time this year, primarily because of some new protocols I added lately and which I desperately needed to get usability to a higher level. As a side effect, some minor things (this one is not a really big project) I developed in the last 6 months are available now too; one of them being Network monitoring. From now on, all Ethernet enabled devices are being monitored, resulting in all kinds of new ideas to make it all work even better than it already did

Hi Robert,

You are very busy lately. I noticed this on your blog site

Or I can issue an alert on the User Interfaces when the printer is on for more than an hour, cause in daily practice only a few sheets are printed and someone forgets to switch the printer off afterwards.

I have made an event the starts a script every 2 minutes to check if there are any files in the printers spooler folder. If that's the case then the printer is turned On for 8 minutes. If the OS (Windows in my case) notice that the printer is online then the printer spooler process starts printing the documents, removes de printed files and the printer will be turned off after the time leaps

Won't this make the devices use more power if you keep waking them up with pings? Just wondering.

If i'm not mistaking, you don't wake up a device with a ping, maybe a magic packet or WOL depending on settings, but not just by pinging...
It might keep some devices from going into standby mode however...

I use the same DLL
did a check on my NAS Synology which takes 14.8w when not use.
If i perform the Ping it goes up to 15.1w, so it comes not out of powersave, but i can measure the ping.
You should check all your devices (agree) because if they go out of powersave its not efficient

I knew about that one, I have read about it before on this forum. Unfortunately my printer is being used directly (no shared spooler folder) from 4 PC's.

For the devices that aren't on 24/7 (and are switched 100% on or 100% off), a ping won't influence power consumption, but yes there are a few that can be: 2 Laptops, 2 PCs and my NAS. All the rest doesn't have a power save mode IIRC. I haven't had the time to check this yet but I will, thanks for the reminder.

your NAS (synology) consumes 0.3 watt more if you ping it
but it stays in sleep mode
