# FILE: repl-monitor.pl
#
# SYNOPSIS:
# repl-monitor.pl [-f configuration-file] [-h host] [-p port] [-r]
# [-c connection] [-a alias] [-k color] [-u refresh-url]
# [-t refresh-interval] [-s] [-W]
#
# repl-monitor.pl -v
#
# DESCRIPTION:
# Given an LDAP replication "supplier" server, crawl over all the ldap
# servers via direct or indirect replication agreements.
# For each master replica discovered, display the maxcsn of the master
# and the replication status of all its lower level replicas.
# All output is in HTML.
#
# OPTIONS:
# -f configuration-file
# The configuration file contains the sections for the connection
# parameters, the server alias, and the thresholds for different colors
# when display the time lags between consumers and master.
# If the Admin Server is running on Windows, the configuration-file
# name may have format "D:/opt/replmon.conf".
#
# The connection parameter section consists of the section name
# followed by one of more connection parameter entries:
#
# [connection]
# host:port:binddn:bindpwd:bindcert
# host:port=shadowport:binddn:bindpwd:bindcert
# ...
#
# where host:port default (*:*) to that in a replication agreement,
# binddn default (*) to "cn=Directory Manager", and bindcert is the
# pathname of cert db if you want the script to connect to the server
# via SSL. If bindcert is omitted, the connection will be simple
# bind.
# "port=shadowport" means to use shadowport instead of port if port
# is specified in the replication agreement. This is useful when
# for example, ssl port is specified in a replication agreement,
# but you can't access the cert db from the machine where this
# script is running. So you could let the script to map the ssl
# port to a non-ssl port and use the simple bind.
#
# A server may have a dedicated or a share entry in the connection
# section. The script will find out the most matched entry for a given
# server. For example, if all the ldap servers except host1 share the
# same binddn and bindpassword, the connection section then just need
# two entries:
#
# [connection]
# *:*:binddn:bindpassword:
# host1:*:binddn:bindpassword:
#
# If a host:port is assigned an alias, then the alias instead of
# host:port will be displayed in The output file. Each host:port
# can have only one alias. But each alias may be used by more than
# one host:port.
#
# [alias]
# alias = host:port
# ...
#
# CSN time lags between masters and consumers might be displayed in
# different colors based on their range. The thresholds for different
# colors may be specified in color section:
#
# [color]
# lowmark (in minutes) = color
# ...
#
# If the color section or color entry is missing, the default color
# set is: green for [0-5) minutes lag, yellow [5-60), and red 60 and more.
#
# The following three options (-c, -a, -k) are used if not providing a
# configuration file:
#
# -c connection
# The connection value is the same as the configuration file value(see above):
# -c "host:port:binddn:bindpwd:bindcert"
#
# -a alias
# The alias value is the same as the configuration file value(see above):
# -a "alias=host:port"
#
# -k color
# The color value is written as "lowmark:color". Where the lowmark is in minutes.
# This option is ignored if printing a plain text report.
# -k "5=#ccffcc"
#
# -h host
# Initial replication supplier's host. Default to the current host.
#
# -p port
# Initial replication supplier's port. Default to 389.
#
# -r If specified, -r causes the routine to be entered without printing
# HTML header information. This is suitable when making multiple calls
# to this routine (e.g. when specifying multiple, different, "unrelated"
# supplier servers) and expecting a single HTML output.
#
# -t refresh-interval
# Specify the refresh interval in seconds. This option has to be
# jointly used with option -u.
#
# -u refresh-url
# The output HTML file may invoke a CGI program periodically. If
# this CGI program in turn calls this script, the effect is that
# the output HTML file would automatically refresh itself. This
# is useful for continuing monitoring. See also option -t.
#
# -s Print output in plain text, instead of HTML.
#
# -W Prompt for connection passwords.
#
# -?, --help
# Print usage.
#
# -v Print out the version of this script
#
# DIAGNOSTICS:
# There are several ways to invoke this script if you got error
# "Can't locate Mozilla/LDAP/Conn.pm in @INC", or
# "usage: Undefined variable":
#
# 0. Prerequisite: NSPR, NSS, Mozilla LDAP C SDK, PerLDAP
#
# 1. Run this perl script via repl-monitor, which sets up LD_LIBRARY_PATH
# $ repl-monitor
#
# 2. If 1 does not work, try invoking this script as follows.
# Assuming <MYPERLDIR> contains Mozilla/LDAP:
# perl -I <MYPERLDIR> repl-monitor.pl
#

# enable the use of our bundled perldap with our bundled ldapsdk libraries
# all of this nonsense can be omitted if the mozldapsdk and perldap are
# installed in the operating system locations (e.g. /usr/lib /usr/lib/perl5)
# this script is always invoked by repl-monitor-cgi.pl, which sets all of these
# If using this script standalone, be sure to set the shared lib path and
# the path to the perldap modules.
