LOGCHECK -- Checks log files for strings Alton Moore
which signify good or failed Fidonet 1:397/5264 (NEC)
net connections in batch. WWIVnet 1@1042
Version 1.0, 08/16/1992
---------------------------------------------------------------------------
INTRODUCTION:
-------------
This program is intended to determine whether a network transfer occurred
(say at least once per night) by scanning a network log file for a
specified string. The addition to the log of text containing this string
causes the program to exit with a certain error level, which you may use
in your batch files to determine whether the network transfer just
attempted was successful.
Although this program is not network-specific in any way, I will
generally give examples for a FrontDoor/WWIV setup.
THEORY OF OPERATION:
--------------------
The program will perform 2 functions: marking the current size of a given
log file and checking that file for the addition of text containing a
target string (say "connected"). These functions are meant to be used
before and after a network transfer attempt to determine whether the
attempt was successful. These functions, in conjunction with a flag
file, can be used to ensure that, for example, your system calls another
system at least once per night. The first step would be to create a flag
file (probably in batch) as soon as you want your system to start trying
to call the target system. You would create an event which created your
flag file:
.
.
echo This file's presence causes my FrontDoor batch file to do a WWIV callout!
>\bbs-util\wwiv1040.flg <--- continuation of previous line
.
.
Then, at some point in your batch file which is often traveled by your system,
for example just after every net connection or human caller, you might put:
.
.
if exist \bbs-util\wwiv1040.flg goto wwiv_callout
.
.
And then, the actual callout code:
:wwiv_callout
cd \wwiv
\wwiv\utility\logcheck -m \wwiv\gfiles\netdat0.log
\wwiv\utility\clout.exe 1040 1
\wwiv\utility\logcheck -p 5
\wwiv\utility\logcheck -s connected
if errorlevel 1 goto run_frontdoor
del \bbs-util\wwiv1040.flg
goto run_frontdoor
Note that above, in the first invocation of the program, -m is used as
the first argument to indicate storing the name of the file we're
referring to (supplied as the second argument) as the first line of the
holding file logcheck.dat and the current size as the second line.
The -p invocation prints out the addition to the log file to the screen,
pausing for 5 seconds to let you get a gander at the results!
The next invocation (scan, indicated by -s) scans the file stored as
the first line of logcheck.dat, starting at the byte indicated by the
second line of logcheck.dat. The second argument is the string to scan
for (use quotes to encapsulate strings with odd characters or spaces).
If the string is found, then error code 0 is returned; if not, then 1 is.
SYNTAX:
-------
Run the program with no arguments for the latest help information.
The functions supported by the program are:
-m [logfilespec] remembers the filespec of the log file
and the current size and stores them.
-s [stringtoscanfor] returns 0 if this string was found to be added to
the file since the last mark operation.
-p [delaytime] prints the new part of the log to the screen,
pausing for [delaytime] afterwards.
The error codes returned by the program are:
-m function: 0 = successful
2 = bad parameter (function or filename)
-s function: 0 = successful (string found in new part of log file),
1 = unsuccessful (log file same size or smaller or string
not found in new part of log file)
2 = bad parameter (function or filename)
-p function: Oh, just look at the source....
