SwissMonitor on Linux - 2009/03/07 12:58Is it possible to have a Linux version of the SwissMonitor?
And just for my understanding, what's the difference of the actions taken by the SwissMonitor and a media refresh?

Re: SwissMonitor - 2009/03/07 13:17Is it possible to have a Linux version of the SwissMonitor? SwissMonitor is a Windows application developed in C#. It would need a Linux devloper to convert this and create binaries for Linux distros.
And just for my understanding, what's the difference of the actions taken by the SwissMonitor and a media refresh? SwissMonitor monitors media locations for new files being added and instantly adds them to the database, saving the need to open the SwissCenter config and performing a manual media search.Players : Netgear EVA700 | Popcorn A-100 (100516) | Popcorn A-200 (100208) Webserver : Simese v2.6.4 | Apache 2.2.16 | PHP v5.2.12 | MySQL v5.1.32 Server : Windows 7 Home Premium 64bit Spec : Intel C2Q Q6600 - 4GB RAM - 4TB HDD AV : Pioneer VSX-915 | Samsung LE40C650

So, is there any difference with an automatic media refresh?

Re: SwissMonitor on Linux - 2009/03/07 15:04Hi Klaas...
The only thing SwissMonitor adds is that it instantly adds and removes files. A media refresh does the same thing just not instantly.
We still have to run a scheduled scan because, for instance, it is necessary to update the RSS feeds.Showcenters 1000g/250HD/Popcorn Hour A-100 Netgear HDX101 Powerline Adapters Windows XP SP3 Simese 2.6.4 Beta SwissCenter latest SVN NAS Server Intel PD 2.66Ghz/2GB Mem/1.5TB Storage Hauppauge HVR 1600 GB-PVR

OK, capito, thanks for the explanation.
@all,

Re: SwissMonitor on Linux - 2009/03/14 19:55Since it's written in C# it theoretically might run under Mono but I've no idea if that supports all of the bits SwissMonitor uses like file monitors and services.
If someone wants to write a version for Linux though the calls into SwissCenter to notify it immediately are pretty simple, it's the monitoring bit that might be a little more complex but I'm happy to go through the behaviour of the SwissMonitor with someone if they fancy giving it a go.
Also the full refresh is needed to pick up changes that happened if the SwissMonitor isn't running when they happened and to sort out any consistency issues that can occur in a few rare cases."The mysterious garfoot"

Re: SwissMonitor on Linux - 2009/06/14 14:20To be frank, I think that both the scan and the monitor is the wrong approach for Linux. For one thing, you can't assume that all file systems are local -- there's NFS, which tends to make monitoring quite unreliable, even with a statd.daemon.
The bottlenecks are quite different on Linux -- what takes time is the PHP interpretation, not the file system scanning.
Example:
# time find /usr/storage/music -type f | wc -l 5683
real 0m0.040s user 0m0.008s sys 0m0.032s
That's 0.04 seconds in total to find and list all 5683 music files in a storage area. This is on a 2001 era PIII machine, and old PATA drives.
In Linux, one can take advantage of the much faster file system access. A diff of two complete finds would identify every new or deleted file, and a find with a "-newer /last/scanned" parameter would find all changed files.
A test I wrote in /bin/sh doing just this completed updating in about 1 second, unless there were massive changes. The reason why I didn't pursue it further was that it could cause conflicts if run at the same time as media_search.php or database accesses from Swisscenter (add locking!).
What WOULD be very useful would be a php that would take two parameters -- the repository and a file name. And then add/update/delete that file depending on whether it exists or not.

This is how SwissMonitor interfaces with SwissCenter.
SwissMonitor requests the URL /media_monitor.php specifying parameters that identify the file that has changed (and what type of change). SwissCenter then processes the file accordingly.
It would be simple to take the output from two file diffs and then use wget to "call" the media_monitor.php script with the correct parameters for all files added, updated or deleted.

Re: SwissMonitor on Linux - 2009/06/15 18:52Does this mean (in plain English) that we get a monitor for Linux on a short term ... ... would be great ...
