LEDcontroller: control your LED's & HTPCmonitor: keep an eye on your PC (1 Viewer)

This should work yes, but only the events for MP Server, the other events are just for the computer on wich it is installed.

I've notice a couple of problems - maybe related. These were with COMswitch, so I updated to your LEDcontroller version and - at least the first issue still remains (not had time to see the second since)...

First, the resource use of COMswitch (and now LEDcontroller) seems very high, especially the CPU usage. See the attached Task Manager snapshot - in my case CPU continually hovers around 2-4% all the time! Is this because it's continually polling for state changes? If so, is it possible to maybe add a config value to extend the polling interval? I don't mind if the LED takes an extra 5 secs to turn on/off [As a side note, the memory usage seems high too, but not so important IMO]

Second, I get .NET error popups occasionally. From the details (see second snapshot), it looks like COMswitch was polling something and the net link was down. This tends to happen on wake from standby (maybe a race condition?), but I'm thinking a reduce poll might improve or cure this too. Note: this is ugly more than anything else, if I click "Continue" on the popup, most times everything seems to work fine.

Thanks!

The CPU usage is probably because it indeed checks every second, I will make an update so that it would be configurable, will also fix the error ASAP

Wich are the vents you are using?

I've fixe the bug and added your request.

The actual CPU usage isn't something I can reduce, but I have it running quite some time and never experienced nasty side affects so....

Wow! Thanks for the quick response!

I just tried the new version - unfortunately it made the CPU usage worse (ooops!). With this version CPU hovers between 6 and 8% - went back to the old version and the usage went back down to 2-4%

Changing the poll rate doesn't seem to affect the CPU either. I tried the default 1sec, also 5secs, and even 1/2 a sec. Cpu util stayed about the same in each case. It does depend on the event type though... for the "Power on" event (this is a single box system) CPU is 0%. But for *single* MediaPortal events (e.g. recording or timeshifting) its the 6-8% figure.

What's worse though, is that with multiple events the CPU rises even more. The snapshot below is with the latest version, polling set at 5 secs and three MP events: Grabbing EPG, Timeshift & Recording (I know these are all on one LED for example purposes, but it's the same if they are spread across three LEDs). As you can see the LEDcontroller CPU util is over 30%!! But also note that the TVServer is now also hovering in the 10-12% range as well! Thus nearly 50% CPU usage with *nothing* else going on - not even MP client is started. And this is on a Core2 Duo CPU. I think something else is going on here - it can't possibly need that much CPU to do three polls every 5 secs.

Sorry to harp on, this is a VERY useful tool! Thanks for the help.

I'll look into it, the added CPU usage is probably because the extra check that happens because of your bug when no network was avalable.


But with the time setting, if you set it to 5 sec, isn't the CPU usage high every 5 sec or still continiously?

Usage stays high continuously - hovering around 6-8% for one event. Similarly, for 3 events it stays around 31% (plus or minus ~2%) all the time. Key thing is that the usage of the TVserver also goes up and stays up in the same circumstances - leading me to think that the polling is actually much higher than the configured 5 secs.

One other datapoint (though I can't see that it's relevant) is that I also have For the Record installed.

<EDIT> I snapshot the process monitor graph for a period of time (attached). The first three horizontal graph-segments (about 5 secs each) are with 3 events configured, the next 6-7 are with just 2 events config'd, and the last 3 segments are with just 1 event. The left hand core history shows there's a pretty consistent usage within these diff configured periods (one vertical segment = 20% utilisation of a single core).

hi,


would love to use your plugin, but my only com port is used for my momolight.

so, is there a chance that you add the use of the lpt port? Just select the port you want in the config.

Look at first page, this should solve your problems

I have no plans in the immediate future to add this.

Man, you RULE! Yep, this has fixed it and it's now working great!

Attached is a graph of (just) one event at a poll rate of 3secs... CPU util is in the noise. THANK YOU!

 

[fmulders]

Yes,...

I had the same problems, but did not know it was related to Ledcontroller.
The last update fixed it indeed. (the same two problems as meq123)
Thanx a lot this is very usefull extension, appreciate the good work.

There is just one extra thing that I would like.
This version only can show there is a recording going on. (TvServer active)
But I have a dual tuner card installed so I would like to see if there are one or two tuners in use.

Can you add this extra functionallity?

(just saw the light after 4 year MCE/VMC use. Mediaportal is way better, but you all knew that offcourse)
