UG Advanced Information

If you double click on a torrent in the main display tab called "My Torrents" you will open a new tab named after that torrent. In that tab there are seven sub-displays giving advanced information about that torrent.

General tab

All the information about the torrent such as per-torrent transfer rate, detailed info about the torrent, tracker status etc. The meanings are explained below.

Graphical section

This unnamed section gives graphical information about the selected torrent. This has two blue horizontal bars at the top. The topmost should become solid blue while your download advances, indicating that you have 100% of the torrented resource in the end. The lower one is marked Availability. This is a graphic indicator of how "available" each of the pieces of the file is among the peers you are seeding to. If a stripe is dark blue, it means that section of the file has the highest availability among all pieces. If a stripe is white, it means that section of the file has the lowest availability among all pieces. Colors in between stand for varying levels of availability. If there are more pieces of the file than there are pixels in your progress bar, the availabilities of all the pieces covered by that pixel stripe are averaged together to get the color.

Transfer section

This section contains information about the the transfer of the selected torrent. Most of the entries in this section are self-explanatory. If you don't understand a word, have a look at This funny word. Don't be confused when the number of peers/seeds you are connected to is bigger than the number of peers/seeds in the swarm. This simply means that Azureus could find peers/swarms unknown to the tracker via the distributed hash table.

Info section

This section contains information about the selected torrent itself. Furthermore, this section provides information about the tracker status. You can check if the tracker is running ok or if you have problems connecting, temporarily (timeout) or probably permanently (connection refused). A scrape error is not critical at all (it just means the tracker will not tell you the total number of seeds and peers in the swarm). You can also manually initiate a tracker update by clicking the corresponding button.

Average Swarm Speed

Peers tab

This tab contains various information about the peers you are connection to for the selected torrent. You can find a detailed descrption below.

• IP of the peer you are connected to
• T Is "l" (local) if you established the connection, r (remote) if the peer did
• Pieces the peer has
• % Percent downloaded by the peer
• Down Speed your downloading speed from the peer
• Down Your overall download from the peer
• Up speed Your uploading speed to the peer
• Up Your overall upload to the peer
• Stat Up An estimated value of the upload speed of the peer
• Overall Down Speed The total download speed of the peer
• S A peer can be snubbed for not delivering data at a high enough rate. This snubbing can be set manually.
• Opt. Unchoke (Optimistic Unchoke) In the decision making of whom to unchoke, random has its place.
• Client Type of BT client the peer is using
• Discarded Amount of discarded data send by the peer.

The flags of the countries your peers are located in can be displayed thanks to the CountryLocator plugin. Install it, go to this details view, right-click and select the columns to display.

Swarm tab

In a nutshell, this tab graphically displays the swarm of the torrent. More details are provided below.

I call the swarm GUI (Graphical User Interface) the "Giant Eye" because when you have enough connections that is what is looks like! If you have more information about the interface then please edit this page.

If you are not sure what I am talking about, then double click on an active torrent in your main GUI...click on the "Swarm" tab...maximize your screen, sit back and be hypnotized.

Key to the secrets of the "Giant Eye"....(in Layman's terms...of course things are a little more complicated than this)

• The Grey circle indicates...that the computer you are connected to has been snubbed. This basically mean that it was so slow last time information was sent/received, that it isn't a good option for the next connection.

• The light blue lines indicate your upload connections. The box travelling along them is information travelling to another user. The speed the box is travelling at shows you how fast that connection is...

• The darker blue lines indicate your download connections. The box travelling along them is information travelling to you. The speed the box is travelling at shows you how fast that connection is...

• The pie chart in the middle of the "Giant Eye" is your copy of the file. It is a pie chart representation of your completed download, so a half full pie chart means half the file has been downloaded.

Pieces tab

Each torrent that you are downloading is divided into many small pieces to make transfer simpler. In addition, pieces are themselves split into a number of blocks of a fixed size. The pieces tab provides you with information about these items for the selected torrent.

This tab contains information about the pieces currently being downloaded.

• # The number of the piece
• Size is the size of the blocks for this piece
• # of blocks is the number of blocks in this piece
• Blocks shows which blocks in the piece have been transferred. They key is the following:
  • Requested The block is requested (i.e. not downloaded yet)
  • Written The block is downloaded and written on your hard drive
  • Downloaded, write pending The block is downloaded but not yet written on your hard drive
  • Data is in Cache The block is held in the cache
• Completed is the number of blocks that have been successfully transferred
• Availability shows how well the block is distributed. For further information check out the availability page.
• Type shows whether a piece is considerd slow or fast. Slow/fast is the categorisation of the peers that contribute to this piece. This was introduced in Azureus in order to limit the effect of "1 small block from a slow peer is blocking the piece completion". So all the slow peers contribute to "slow" pieces, and all the "fast" peers contribute to fast pieces. It helps keeping the number of concurrent pieces low, and so, the cache effect. The limit is at about 2kB/s, so it's really to avoid "blocking peers" from blocking pieces.

Files tab

This tab gives an overview of what files actually are in that torrent.

So if the torrent is in fact one file then this will not be very useful. If, however, the torrent is composed of many files then you can control priority and monitor progress on individual files within the torrent. This can be useful if a torrent contains many files of which in fact you only need a few, in this case you could mark some files as lower priority or even instruct Azureus to not download files you don't need from within the torrent.

Options tab

This tab allows you to adjust the per-torrent options.

Console tab

You can have a look at all the console/debug output done by Azureus in this tab.

You can only see the output if you have the logging enabled in the logging tab of the options. You also have a few possibilities to alter the way the logging occurs:

• Pause Logging pauses the logging as long as the checkbox is marked.
• Update in real time lets the output be displayed in real time. If this checkbox is unchecked, the output is cached and only written to the console from time to time.
• Auto-scroll turns on auto-scrolling for the output. This lets you see always the latest output without having to scroll manually.
• Filter In this block you can choose what information you want to see. This helps you to minimize the output to exactly the things you are interested in. If you don't filter the output, it's likely you'll never find what you're looking for.
