Corrupted data in BBALPHAMSG?
Has anyone noticed what appears to be corruption in BBALPHAMSG? I have only noticed this behavior (so far) on disk checks and it always follows the backslash between the Total Space and Available Space. It also seems to be consistent from host to host (ex. The host below will have the same corruption for each disk check other hosts may show slightly different characters but not all hosts exhibit errors).
Within my email script all I am doing is 'echo "$BBALPHAMSG" >tmpfile'.
Xymon Server: Ubuntu 10.04 Client (in this instance): W2k3 Server
The actual client data appears to be just as expected with no odd characters (this is pulled from the "Client data" link on the Xymon page):

John,
The "corrupted characters" you are seeing are the ASCII characters corresponding to the number after the \ character. e.g. \4 -> ^D, \44 -> $, etc. It looks like the string is being passed to something like a string formatting function (e.g. sprintf) without being properly quoted to escape '\' characters.
What version of Xymon are you using?

That is exactly what I was thinking.
Xymon version 4.3.0
In my script I get the results as follows:
Echo $BBALPHAMSG (everything is fine – except for formatting which is what I am trying to correct)Echo “$BBALPHAMSG” >file (message is written to file and formatting is as I would like but the “\*” characters are converted as described below)Echo $BBALPHAMSG >file (same as above but message is not formatted)
I have tried to pipe both of these through sed before sending to the file but that still isn’t working as the characters are converted prior to the pipe.
There has got to be a way that I can write these to a file but I am just missing something simple.
Thanks, John

John,

Xymon version 4.3.0
In my script I get the results as follows:
Echo $BBALPHAMSG (everything is fine – except forformatting which is what I am trying to correct)
Echo “$BBALPHAMSG” >file (message is written to file andformatting is as I would like but the “\*” characters are converted as described below)
Echo $BBALPHAMSG >file (same as above but message is notformatted)
So it's in a shell script you're writing? Just don't enclose $BBALPHAMSG in double quotes and you'll be fine. If it's a BASH script, then the behaviour above is as documented - see 'man bash' under QUOTING:
... Enclosing characters in double quotes preserves the literal value of all characters within the quotes, with the exception of $, ‘, \, and, when history expansion is enabled, !. The characters $ and ‘ retain their special meaning within double quotes. The backslash retains its special meaning only when fol- lowed by one of the following characters: $, ‘, ", \, or <newline>. A double quote may be quoted within double quotes by preceding it with a backslash. If enabled, history expansion will be performed unless an ! appearing in double quotes is escaped using a backslash. The backslash preceding the ! is not removed. ... Words of the form $'string' are treated specially. The word expands to string, with backslash-escaped characters replaced as specified by the ANSI C standard. Backslash escape sequences, if present, are decoded as follows: \a alert (bell) \b backspace \e an escape character \f form feed \n new line \r carriage return \t horizontal tab \v vertical tab \\ backslash \' single quote \nnn the eight-bit character whose value is the octal value nnn (one to three digits) \xHH the eight-bit character whose value is the hexadecimal value HH (one or two hex digits) \cx a control-x character ...
David.
I have tried to pipe both of these through sed before sending to the file but that still isn’t working as the characters are converted prior to the pipe.
There has got to be a way that I can write these to a file but I am just missing something simple.
