TremSnaps is a web app that captures the state of the entire Tremulous network. The state of each server, and each player, is written to a snapshot that can then be viewed by visitors. One snapshot is about 150 KB.

Installation
Just unzip it into whatever directory you like. Make sure PHP has full read/write access to the entire directory, or weird things can happen.

Automatic Snapshots
TremSnaps doesn't take snapshots on its own. You'll have to set up a cron job or something equivalent.

Code: [Select]

0 * * * * tremsnaps/snapshot.php

This would generate a snapshot every hour.

Configuring
The configuration file is common/config.php.

One Megabyte? Can't you compress it or use another method for data storage?

Looks promising. I'll have a look at it later today.

David · « **Reply #2 on:** October 18, 2008, 09:29:31 pm »

What the hell are you storing?
qstat -R -P only comes out to 141k, 24k gzipped.

Syntac · « **Reply #3 on:** October 18, 2008, 09:50:59 pm »

Crap, I was way off. It's about 150 KB. Turns out Mac OS X uses screwy estimation and you have to look at the number of bytes in order to find the real size.

What does "server with stupid names" mean?

Syntac · « **Reply #5 on:** October 19, 2008, 12:51:18 am »

Heh, I was hoping someone would ask that. You know how some server owners put black "A"s in front of the title? Well, TremSnaps detects that.

It also removes boxes and deals with nonstandard color escapes.

Hello,
Excuse-me of my newbieness, but does it works on Linux/Windows ?

It's a php script - it works on almost any OS (well, at least on those where Tremulous runs on)

Syntac · « **Reply #8 on:** November 01, 2008, 01:33:54 am »

It works on all platforms that support the Apache (2?) web server and PHP 5.

Works!

Did you set up a cron job?

Nop, sorry. Actually, I'm on windows (I have Ubuntu too, but I need to fix some things before) and I don't know how to set up a

cron on it.
And it's not my own server, it's the one of Symphony/Haptism, a french (??), who hosts me.

Syntac · « **Reply #12 on:** November 01, 2008, 04:27:55 am »

Ohhh... Well, I'm just glad someone was able to get TremSnaps working.

EDIT : Btw, you should remove the stupid/not correct server's name system. Because some servers who have a correct name are not listed...

Syntac · « **Reply #15 on:** November 01, 2008, 04:41:53 pm »

Aargh, there's more wrong with Mac OS X's zip program than I thought! I'll repackage it as a ~~gzip~~ less defective archive.

Amanieu · « **Reply #16 on:** November 01, 2008, 04:46:59 pm »

Why is the Tremfusion Test Server not on the list

Syntac · « **Reply #17 on:** November 01, 2008, 04:48:43 pm »

Not sure. Could be due to packet loss.

Archangel · « **Reply #18 on:** November 01, 2008, 08:50:54 pm »

Yeah. there are a lot of servers that are fairly good that use boxes. I'd say just strip out the boxes, but still print the servers.

Syntac · « **Reply #19 on:** November 01, 2008, 08:59:41 pm »

It does. Boxes are stripped out when the list is retrieved.

Archangel · « **Reply #20 on:** November 01, 2008, 10:08:21 pm »

I see none of my servers, and they're all local to the machine.

Syntac · « **Reply #21 on:** November 01, 2008, 10:11:43 pm »

TremSnaps retrieves the list from the master server.

Archangel · « **Reply #22 on:** November 01, 2008, 10:50:25 pm »

I'm well aware. What I am saying is, none of my servers are showing up, and they can't possibly be timing out.

There could be packet loss that corrupts the list entry (and causes it to be removed), or something that prevents TremSnaps from connecting. Then there's the possibility of your servers not being public.

Archangel · « **Reply #25 on:** November 02, 2008, 01:54:21 am »

The fact that they're on a 100mbit line, with a 20ms ping to the master server, and they haven't gone down for over 70 days, leads me to believe there is a bug in your code.

Syntac · « **Reply #26 on:** November 02, 2008, 01:05:43 am »

There is very little possibility of there being a bug. This is all my code does:
• Fetches a list from the master server (stripping out corrupted entries).
• For each server on that list, connects to it and retrieves information.
• Writes the accumulated data to a collection of files.
If you tell me what your servers' names are, I'll be happy to troubleshoot this myself.

[EDIT] Double negative...

By the way, all the files in your current zip are gz'ed. Might want to fix that.

Dammit, I know I'm in trouble when someone makes a diff of my code...

All that aside, thanks Undeference. Will give it a try.

Syntac · « **Reply #29 on:** November 02, 2008, 01:38:58 am »

I will shortly be remaking TremSnaps into a command-line tool. Projected features include:
• Scope options
• Flat-file dumps
• Rcon console
• Dump readback
• And probably more...
