Monitoring Syndication Progress
After the syndication relationship was
setup, we monitored the progress of the data replication between
syndicators and subscribers for details such as whether syndication was
successful, when it occurred, and how many changes were included.
Monitor Syndicator/Subscriber Views
We started monitoring the syndication process by observing the Syndicator
and Subscriber views. The screenshots below illustrates the new status visible
in the Syndicator and Subscriber views.
Figure: Web Content Subscribers View – Status Active
Figure: Web Content Syndicators View – Status Active
The table below provides details about the various different status that are
possible and provides a brief description –
Status |
Description |
Idle |
The syndication process is idle. |
Pending |
The syndicator has received a request, but
it has yet to initiate it. |
Queued |
The syndicator has sent a request to the
syndication application, but syndication is not yet active. This state will not
occur if the subscriber has initiated syndication. The status remains as Idle
until syndication begins and the status then changes to Active. |
Active |
The syndication process is active. |
Disabled |
The syndication process is disabled. If
syndication was already in process prior to being disabled, the status can be a
combination of Disabled and Pending, Queued, or Active. |
Once the syndication process has completed, the Syndicator and Subscriber
views displayed the idle status as illustrated in the screenshots below.

Monitor the Synicator/Subscriber Status Report
We used the Last Update column entry links on the syndicator and subscriber
to review the Syndicator and Subscriber status reports as illustrated in the
screenshots provided below.

The following table describes the information available in the Syndicator
and Subscriber status reports.
Field Name |
Description |
Syndicator and subscriber ID, name, and URL
|
This information provides identifying
details about the syndicator and subscriber that are engaged in syndication.
|
Enabled |
This field indicates whether syndication is
enabled for the syndicator or subscriber. |
Type |
This field indicates whether partial or
full syndication occurred. With partial syndication, only those items that have
been updated since the last syndication are replicated. Full syndication
replicates all items, regardless of whether they have been updated since the
last syndication. |
Started and finished time stamps |
These fields provide the date and time when
syndication started and finished. |
Result |
This field indicates whether syndication
was successful. |
Detail |
This field provides detailed information
about the syndication result, including any errors that occurred during
syndication. |
Updates sent |
This field indicates the number of items
that have been updated. This includes new items that have been added and
existing items that have been updated. |
Removes sent |
This field indicates the number of items
that have been removed. |
Old state and new state for subscriber or
syndicator |
This field displays state information for a
syndicator or subscriber before and after syndication occurred. This
information is provided for the opposite member of the syndication
relationship, so for example if you are viewing syndication results for a
syndicator, the old and new states for the subscriber are displayed.
If successful, this field indicates the actual change of status. If
syndication has failed, this indicates what should have been the change of
status.
Note: The syndication state only displays a list of item gatherer
ids and the current state. It is designed to be used as a diagnostic tool when
troubleshooting syndication. |
Update summary |
This lists:
- the number of updates sent
- the number of successful updates
- the number of failed updated
Note: The number of updates listed here does not directly relate to
the number of items updated. For example, if you create a library and then
create a taxonomy item in the library, you have updated a single item. However
in the Update summary this will be displayed as three updates; one for the
library, one for the new taxonomy and one for its version. |
Update details |
This section provides additional
information to the Update summary section. It lists:
- the number of items that didn't require an update because they
have already been updated
- the number of new items created
- the number of items updated
- the number of failed updates
- the number of items that didn't require removal because they have
already been removed
- the number of items removed
- the number of failed removals
|
Monitor the Subscriber directory
Once Syndication has started, you can monitor its progress by looking at the
<WP_Profile>\PortalServer\wcm\ilwwcm\system\subscriber\<SUBSCRIBER-ICE-
ID> directory on the Subscriber server.
As items are being retrieved from the Syndicator, this directory will grow.
After all items are retrieved, they will start to be saved within the
Subscribers repository. As each item is saved in the repository, its
corresponding file entry will be removed from the above directory.
The screenshots provide below illustrates this.

Figure: Subscribers File System Directory after Syndication
Files can remain in the subscriber directory for any of the following
reasons:
- A failed attempt to save to the database due to a software error
- Syndication is interrupted or killed before it completes writing to the
database
- WCM is not handling the syndication changes properly
Monitor the logs
Once the syndication process is completed, we noticed the following entries
in the SystemOut.log for the Syndicator and the Subscriber
Syndicator logs
