# Analog 6.0: Configuring the output

So far we have mainly discussed commands which control how analog reads the logfiles. We now get on to commands for configuring the output.

First, you can change the style of the output using the `OUTPUT` command. There are seven possible output styles, called `XHTML`, `HTML`, `PLAIN`, `ASCII`, `XML`, `LATEX` and `COMPUTER`.

`XHTML` is the default. It produces web pages in XHTML 1.0. `HTML` produces web pages in HTML 2.0.

`PLAIN` produces plain text files, and `ASCII` is the same as `PLAIN` except that it uses all ASCII characters (no accents etc.) if possible. (This is because some applications don't understand accented characters).

`LATEX` produces LaTeX code which can be turned into PDF if you have the `pdflatex` command installed. (If you want to use the ordinary `latex` command, specify `PDFLATEX OFF`.) It's only available with certain European languages (US-ASCII, ISO-8859-1 and ISO-8859-2 character sets). Yes, I know it gives overfull hboxes sometimes.

`COMPUTER` is a special format suitable for reading by a computer (useful for reading into a spreadsheet, or post-processing with a graphics package, for example). There is a separate section about this format later.

`XML` produces an XML output which is an alternative format for post-processing. The DTD for the XML output is distributed with the program. You can find more information about the XML style, and an example of a post-processing program, at http://timian.jessen.ch/.

As well as a command like

    OUTPUT PLAIN

you can also select `PLAIN` style with the command line argument `+a`, and `XHTML` with the command line argument `-a`.

You can also specify `OUTPUT NONE` for no output, if you are producing a cache file.

Next, you can change the language of the output. There are two ways to do this. The usual way is to use the `LANGUAGE` command. For example, the command

    LANGUAGE FRENCH

will give you the output in French. The available languages at the moment are `ARMENIAN`, `BASQUE`, `BULGARIAN` (Windows-1251), `BULGARIAN-MIK` (MIK-16), `CATALAN`, `SIMP-CHINESE` (GB2312), `TRAD-CHINESE` (Big5), `CZECH` (ISO Latin 2), `CZECH-1250` (Windows-1250), `DANISH`, `DUTCH`, `ENGLISH`, `US-ENGLISH`, `FINNISH`, `FRENCH`, `GERMAN`, `HUNGARIAN`, `INDONESIAN`, `ITALIAN`, `JAPANESE-EUC` (EUC-JP), `JAPANESE-JIS` (ISO-2022-JP), `JAPANESE-SJIS` (SJIS), `JAPANESE-UTF` (UTF-8), `KOREAN`, `LATVIAN`, `NORWEGIAN` (Bokmål), `NYNORSK`, `POLISH`, `PORTUGUESE`, `BR-PORTUGUESE`, `RUSSIAN` (KOI8-R), `RUSSIAN-1251` (Windows-1251), `SERBIAN`, `SLOVAK` (ISO Latin 2), `SLOVAK-1250` (Windows-1250), `SLOVENE` (ISO Latin 2), `SLOVENE-1250` (Windows-1250), `SPANISH`, `SWEDISH`, `SWEDISH-ALT` (alternative translation avoiding Anglicisms), `TURKISH` and `UKRAINIAN`.

The following languages were available for previous versions of analog, but have not yet been translated for version 5: `BOSNIAN`, `CROATIAN`, `GREEK`, `ICELANDIC`, `LITHUANIAN` and `ROMANIAN`. As and when they are translated, they will be added to the analog home page. If you want to translate any of them (or any other language), I would be delighted! See below.

The other way to specify a language is to use the `LANGFILE` command. This is useful if you want to download a new language from the analog home page, or if you want to translate one yourself, or even if you want to change some words or phrases or the way the dates and times are formatted in the output. The `LANGFILE` command tells analog in which file to find the various words and phrases for a new language. For example, the command

    LANGFILE guarani.lng   # or
    LANGFILE /usr/etc/httpd/analog/lang/guarani.lng

would read from that file. If the name of the file doesn't include a directory, it will be looked for wherever analog normally expects to find its language files.

Some languages also have domains files or report descriptions files available. These are normally selected automatically by the `LANGUAGE` command. But you can tell analog to use different ones with the `DOMAINSFILE` and `DESCFILE` commands. Also, some languages have translations of the form interface or configuration file.

If you want to translate another language, I would be delighted! Do contact me first to make sure that no-one else is already translating the same language. The file `README.txt` in the language directory, and the English language file, contain some brief instructions for translating new languages.

Equally, if you find any mistakes in the output in different languages, please do let me know because I'm not able to check them all myself!

You can change which file the output goes to with a command like

    OUTFILE stats.htm

or with a command line argument like `+Ostats.htm`. If you use the filename `-` or `stdout`, the output will go to standard output, which is normally the screen, but Unix users might like to redirect it to another file or even into a pipe. You can also use an absolute path name, like

    OUTFILE /usr/bin/httpd/htdocs/stats.html  # Unix
    OUTFILE "Hard Disk:Server Apps:WebSTAR:Analog:Report.html" # Mac

If the name of the `OUTFILE` doesn't include a directory, it will be put wherever analog expects to put its output files. (This location is built in when the program is compiled.) For example, on Windows it would be in the same folder as the analog executable. But if you use the `+O` command line argument, the file is within the current directory.

You can include date codes in the `OUTFILE` in exactly the same way as for the `LOGFILE`. So for example,

    OUTFILE stats%y%M%D.html

will produce filenames like `stats990501.html`. As with the `LOGFILE`, the date used is the `TO` date if one was specified, and otherwise the time of the start of the program.

Next, you need to know how to turn the different reports on and off. There are 44 different reports which analog can produce, if your web server has been configured to record the necessary data in the logfiles. Each one has a short name, and a code letter or number, as follows. (Note that the code letters are case sensitive: `Z` is quite different from `z`, for example).

    x  GENERAL         General Summary

    c  STATUS          Status Code Report

For details on what the various reports mean, and a summary of the commands which control them, see the section on Analog's reports.

You can turn each report on or off with configuration commands like

    FIVEREP OFF
    REFSITE ON

or by using command line arguments like `-5` and `+s`. You can also turn all reports except the General Summary on or off with the commands `ALL ON` and `ALL OFF`, or with the command line arguments `+A` and `-A`.

You can turn the descriptions of each report off with the command

    DESCRIPTIONS OFF

Even if `DESCRIPTIONS` is `ON`, the descriptions will only appear if analog can find a report descriptions file in your language, or if you specify one using the `DESCFILE` command: for example,

    DESCFILE descriptions.txt

If the name of the descriptions file doesn't include a directory, it will be looked for wherever analog normally expects to find its language files.

You can turn the "Go To" lines in the output off with the command

    GOTOS OFF

`GOTOS ON` turns them on again, and `GOTOS FEW` puts the "Go To" lines just at the top and bottom. `GOTOS OFF` can be abbreviated with the `-X` command line argument, and `GOTOS ON` with `+X`.

You can turn off the "Program started at" line at the top of the output, and the "Running Time" line at the bottom, with the command

    RUNTIME OFF

and turn them on again with `RUNTIME ON`.

The figures in parentheses in the General Summary are for the last seven days: either the seven days before the `TO` time, or if no `TO` time is given, the seven days before the time of the program start. The figures for the last seven days are normally included if some, but not all, of the requests fall in those seven days; but you can turn them off by means of the command

    LASTSEVEN OFF

Of course `LASTSEVEN ON` turns them on again.

You can change the order of the reports by means of the `REPORTORDER` command. You should list the code letters for all possible reports in the order you want them. Non-alphanumeric characters are ignored and so can be used as separators. For example,

    REPORTORDER x-1QmdDhHw4567W-cPz-ritEIYy-SlLZo-sNnfKk-ujJ-vMR-bBp

You can turn the lines in General Summary on and off individually using the `GENSUMLINES` command. The default is

    GENSUMLINES ALL

meaning all available lines. (You always only get the ones relevant to your logfile though.) You can turn lines off using a command like

    GENSUMLINES -KL

(to turn off lines `K` & `L`) and turn them on again with a command like

    GENSUMLINES +K

You can specify the exact set of lines to include with a command like

    GENSUMLINES CDFGHM

You now just need to know which lines have which code letters, which is given in the following table.

``
  Successful requests (always listed)
`B`
  Average successful requests per day
`C`
  Logfile lines without status code
`D`
  Successful requests for pages
`E`
  Average successful requests for pages per day
`F`
  Failed requests
`G`
  Redirected requests
`H`
  Requests with informational status code
`I`
  Distinct files requested
`J`
  Distinct hosts served
`K`
  Corrupt logfile lines
`L`
  Unwanted logfile entries
`M`
  Data transferred
`N`
  Average data transferred per day

There is a command called `IMAGEDIR` which tells analog where the various images used to make the output page should live. It should be a URL, not the actual location on your disk, and it should include the final slash. For example, you could have

    IMAGEDIR img/   # relative URL: within the same directory as the output
    IMAGEDIR /img/  # off the root directory of your server
    IMAGEDIR http://www.myother.server.com/img/  # on another server

Some people are confused about the `IMAGEDIR`. It's just put in the <img> tags in the output. You can see its effect if you look at the HTML source of the output page.

You can use gif images instead of png's for the bar charts by specifying

    PNGIMAGES OFF

`PNGIMAGES` doesn't affect the pie charts, which are always png's: but see the `JPEGCHARTS` command for something similar.

There are four commands which affect the top line of the output. First, the `LOGO` and `LOGOURL` commands allow you to replace the analog logo with another image (for example, your organisation's logo). You can say

    LOGO picture.gif  # for this file
    LOGO /images/picture2.gif  # a different file
    LOGO none         # for no logo

The logo is assumed to be inside the `IMAGEDIR` unless it starts with a slash, or contains `://`

The `LOGOURL` command specifies a URL to link the logo to. If you change the `LOGO`, you probably want to change the `LOGOURL` as well. For example,

    LOGOURL http://www.mycompany.com/
    LOGOURL none   # for no link

The `LOGOURL` command only works with the XHTML output style, not HTML 2.0.

There are commands `HOSTNAME` and `HOSTURL` which affect the name and link at the end of the title line. For example, I might specify

    HOSTNAME "Stephen Turner"
    HOSTURL  http://homepage.ntlworld.com/adelie/stephen/

to generate the title "Web Server Statistics for Stephen Turner". Again, you can use `none` as the `HOSTURL` to specify no link. Analog will normally translate characters in the hostname to HTML if necessary. So to include literal HTML, such as accented characters, in the output you need to precede them by a backslash, like this:

    HOSTNAME "M\&uuml;ller & S\&ouml;hne"

There are commands called `HEADERFILE` and `FOOTERFILE`. These let you specify files to be inserted near the top and bottom of your output. You can also specify

    HEADERFILE none

to cancel a previously-specified header file. Again, if the name of the `HEADERFILE` or `FOOTERFILE` doesn't include a directory, analog will assume a directory, specified when the program was compiled.

There is a command called `STYLESHEET` to specify the URL of a style sheet for the output. This allows you to change the colours etc. (See http://www.w3.org/Style/css/ for how to write a style sheet.) For example,

    STYLESHEET /housestyle.css
    STYLESHEET none   # to cancel it

In the XHTML output style, if you specify a style sheet, it will replace the default one, so you might prefer to use the default one as a base -- you can find it in the directory `examples/css`, along with some other style sheets contributed by users.

There is a command `CSSPREFIX` to add a prefix to all the CSS class names used in the XHTML output style. This is useful to avoid clashes with other style sheets: the disadvantage is that it will make your output longer. For example,

    CSSPREFIX anlg
    CSSPREFIX none    # to cancel it

Of course, if you use your own style sheet, you will have to add the `CSSPREFIX` to all the class names in the style sheet.

There are three related commands called `SEPCHAR`, `REPSEPCHAR` and `DECPOINT`. These specify single characters to be used as the thousands separator in numbers, the thousands separator within the columns in the reports, and the decimal point. Normally, these will be set automatically for the language you choose, but you can change them if you want. For example, a French user might choose

    SEPCHAR " "
    REPSEPCHAR none
    DECPOINT ,

to make "three thousand and a quarter" look like "3 000,25" in text and "3000,25" in the reports.

There is a command called `RAWBYTES`. Specify `RAWBYTES ON` if you want the exact number of bytes to be listed, or `RAWBYTES OFF` if you want the number of kilobytes or Megabytes as appropriate to be listed instead.

If `RAWBYTES` is `OFF` (which is the default), then you can use the `BYTESDP` command to specify how many decimal places you want the bytes rounded to. The default is 2, which will display numbers like "91.26 kilobytes".

There are commands called `HTMLPAGEWIDTH`, `PLAINPAGEWIDTH` and `LATEXPLAINWIDTH` which specify the width of the page. Which one is used depends on whethere the output style is `HTML`/`XHTML`, `PLAIN`/`ASCII`, or `LATEX`. The output is not guaranteed to fit in this width, but analog will take notice of it when choosing the width of the time graphs, when sorting the Host Report alphabetically, when drawing horizontal rules, and when writing some bits of text.

There is a command called `NOROBOTS` which stops robots which obey the robots META tag from indexing your output page or following its links. Normally this is set to `ON` but you can specify `NOROBOTS OFF` if you don't mind robots finding your other pages this way. Note that you will stop far more robots if you also put your stats page in your `robots.txt` file; on the other hand, this file has to be kept up to date by the server administrator.

Sometimes your server is not in the same timezone as you, or at least records the times in its logfiles in a different timezone (for example GMT). So that you can get your statistics in your local time, there is a command called `LOGTIMEOFFSET` to change the time by a certain number of minutes. As with the `LOGFORMAT` command, this only affects logfiles which come later in the same configuration file.

You have to be careful using this command. Because of daylight savings time in operation in different parts of the world at different times, analog cannot attempt to convert between different timezones. So it's your responsibility to set the right offset for different times of year. For example, if you were in Chicago, but your server was recording time in GMT, you would need to specify two different time offsets, one of minus five hours for summer and one of minus six hours for winter. You would need to split your logfiles in the right places and then run commands like

    LOGTIMEOFFSET -300
    LOGFILE summer*.log
    LOGTIMEOFFSET -360
    LOGFILE winter*.log

There is also a related command called `TIMEOFFSET`. This tells analog how much to offset the time of the computer on which it is running (rather than the computer running the server), to get your local time.

In the following sections we shall look at some commands for configuring the output of particular reports, under the following headings: Time reports, Other reports and Hierarchical reports.
