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?

David.
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):

But then when I use BBALPHAMSG within an email script there can be odd
corruption:
