Table 8.6. Directory Server Console Replication Status
8.17.2. Monitoring Replication Status from Administration Express
Although the replication status report in the Directory Server Console shows many details, it does not
show the progress of the replication. Additionally, because one report is generated per agreement, this
lists all status reports for all different agreements.
The
repl-monitor.pl
script, which is explained in detail in the
Directory Server Configuration,
Command, and File Reference
, monitors replication status to a greater extent by providing these
functionalities:
• Lists for each supplier replica on each Directory Server discovered, server URL or alias, replica ID,
replica root, and maximum change sequence number (
maxcsn
).
• Lists corresponding to each supplier replica listed above and for each direct or indirect consumer
replicas discovered, server URL or alias, replica root, replica type, connection type of the replication
sessions, replication schedule, replication status, supplier
maxcsn
, and time lag between the
consumer
maxcsn
and the supplier
maxcsn
.
The time lag field uses different colors to indicate the degree of time lag. The threshold for each
color is configurable.
• Displays the change sequence number (CSN) in human-readable format (instead of hex strings) in
the
MM/DD/YYYY HH:MI Seq# SubSeq#
format, where
Seq#
and
SubSeq#
are omitted if they are
zero.
• Shows the output/result in the HTML format. The script writes the output to an HTML file, which can
be configured to refresh itself automatically; the refresh interval is also configurable.
The script is integrated into the Red Hat Administration Express, so the replication status can be
viewed in a web browser. The Administration Express is an HTML-based version of Red Hat Console
that provides quick access to servers running Administration Server.
To view in-progress status of replication in Administration Express, do the following:
1. Prepare a configuration file following the guidelines provided in the "repl-monitor.pl (Monitor
replication status)" section of the
Directory Server Configuration, Command, and File Reference
.
2. Open the Administration Server URL in a web browser.
