# ms\_isa2dlf(1)

convert Microsoft ISA server logs to DLF

## NAME

ms\_isa2dlf - convert Microsoft ISA server logs to DLF

## SYNOPSIS

**ms\_isa2dlf** **\[***file***\]**

## DESCRIPTION

**ms\_isa2dlf** converts Microsoft Internet Security and Acceleration Server log files in the W3C Extended Log Format to the proxy DLF.  The ISA log files are documented on the section on "Firewall and Web Proxy log fields" in the document "Microsoft Internet Security and Acceleration Server Enterprise Edition" at http://technet.microsoft.com/en-us/library/cc723430.aspx.

## DEBUGGING

As any Lire 2dlf program, this program needs adjusted LR\_DBDIR, LR\_DBFILE, LR\_ID and PATH variables.  These are set in .../etc/lire/defaults and .../etc/lire/profile\_lean.  After manually source-ing these files, one can run this program as a standalone application, by invoking it as e.g.

```
 zcat ms_isa.log.gz | LR_ID=`date +%Y%m%d.%H%M%S` ./ms_isa2dlf > /tmp/dlf
```

.

## EXAMPLES

To process a log as produced by the Microsoft ISA Server:

```
 $ ms_isa2dlf < ms_isa.log
```

ms\_isa2dlf will be rarely used on its own, but is more likely called by lr\_log2report:

```
 $ lr_log2report ms_isa < /var/log/ms_isa.log
```

## THANKS

Chainsaw on OPN irc, for supplying log files.
