これHTMLのひな形にデータを入れている
buf = []
for num, item in enumerate (start_session_logs):
st = item
tm = item["terminate log"]
text = "[ '{0}', '{1}'".format (1+num, st["User"])
text = text + ", new Date({0})".format (st["DateTime"].strftime ('%Y, %m, %d, %H, %M, %S'))
if tm:
text = text + ", new Date({0})".format (tm["DateTime"].strftime ('%Y, %m, %d, %H, %M, %S'))
text = text + "],"
buf.append (text)

日時フィールドが変だから，後ろの有効な値をとる
def toDateTime (log_datetime):
date = (log_datetime.split(' '))[3:]
return datetime.datetime.strptime (' '.join (date), "%b %d %H:%M:%S %Z")

ログのメッセージフィールドから必要な値をとる
def extract_start_session_from_log(line):
sep = line.rstrip().split (': ')
result = {}
result["terminate log"] = None
result["line"] = line
#
result["Message"] = sep[2]
result["Class"] = sep[1]
result["DateTime"] = toDateTime (sep[0])

標準入力から来た行から開始ログ，終了ログを見つけて，それぞれ覚えておく
start_session_logs = []
terminate_session_logs = []
for line in sys.stdin:
if re.search (r'%ASA-[^:]+?-113039:', line):
start_session_logs.append (
extract_start_session_from_log (line))
#
if re.search (r'%ASA-[^:]+?-113019:', line):
terminate_session_logs.append (

覚えておいた開始ログ，終了ログの対応関係を調べる
for start in start_session_logs:
term = next(itertools.ifilter(lambda it:it["DateTime"] >= start["DateTime"] and it["IP"] == start["IP"], terminate_session_logs), None)
if term:
start["terminate log"] = term
term["start log"] = start

対応の評価は開始ログの時間より終了ログが後であることとIPアドレスが一致すること
term = next(itertools.ifilter(lambda it:it["DateTime"] >= start["DateTime"] and it["IP"] == start["IP"], terminate_session_logs), None)

パイプを用意して，出力パイプをファイルディスクリプタ３番にする（もし'3>'の指定が無ければエラーになる）
pipR, pipW = os.pipe ()
os.close (pipR)
os.dup2 (3, pipW)
unterminated_file = os.fdopen (pipW, "w")

対応する終了ログがない開始ログは，次回実行時に処理するためにその行をファイルディスクリプタ３番に送る
for item in itertools.ifilter(lambda it:it["terminate log"] == None, start_session_logs):
print >> unterminated_file, item["line"]

対応する開始ログがない終了ログは，標準エラー出力に送る
for item in itertools.ifilter(lambda it:it["start log"] == None, terminate_session_logs):
print >> sys.stderr, "This record,"
print >> sys.stderr, item["line"] ,
print >> sys.stderr, " has no relationship!"
