# DEV Notes:
|
|
#
|
|
# Regarding the multiline regex:
|
|
#
|
|
# There can be a nunber of non-related lines between the first and second part
|
|
# of this regex maxlines of 10 is quite generious.
|
|
#
|
|
# Note the capture __connid, includes the connection ID, used in second part of regex.
|
|
#
|
|
# The first regex is commented out (but will match also), because it is better to use
|
|
# the host from "end connection" line (uncommented above):
|
|
# - it has the same prefix, searching begins directly with failure message
|
|
# (so faster, because ignores success connections at all)
|
|
# - it is not so vulnerable in case of possible race condition
|
|
#
|
|
# Log example:
|
|
# 2016-10-20T09:54:27.108+0200 [initandlisten] connection accepted from 127.0.0.1:53276 #1 (1 connection now open)
|
|
# 2016-10-20T09:54:27.109+0200 [conn1] authenticate db: test { authenticate: 1, nonce: "xxx", user: "root", key: "xxx" }
|
|
# 2016-10-20T09:54:27.110+0200 [conn1] Failed to authenticate root@test with mechanism MONGODB-CR: AuthenticationFailed UserNotFound Could not find user root@test
|
|
# 2016-11-09T09:54:27.894+0100 [conn1] end connection 127.0.0.1:53276 (0 connections now open)
