Perf Threshold: Site server SINV auth inbox backlog monitor on primary site

Microsoft.SystemCenter2012.ConfigurationManager.Perf_Threshold_Site_server_SINV_auth_inbox_backlog_monitor (UnitMonitor)

This monitor checks the inbox\auth\sinv.box backlog on primary site server. It raises alert if the backlog exceeds the threshold

Knowledge Base article:

Summary

The total number of files in the \auth\sinv.box inbox of the Inventory Data Loader on the site server has exceeded the standard operational threshold.

This folder temporarily stores software inventory files collected from the Configuration Manager client computers.

If the file count keeps increasing beyond the threshold, software inventory information will not be reflected in the Configuration Manager site database in a timely manner.

Causes

The total number of software inventory files can exceed the threshold because:

The SMS_Executive service is stopped or is not responding on the site server.
The site server file processing rate is slower than the incoming rate of software inventory files.
The site server has insufficient resources such as CPU, memory, or disk space.
The Configuration Manager site database has no more space.
The software inventory setting collects data from too many files.
The site server might have lost connectivity to the Configuration Manager site database server.

Resolutions

To resolve this issue and to decrease the number of hardware inventory files:

Verify that the threshold for this alert is not too low and is more than the standard operating threshold for this specific Configuration Manager site.
Verify that the SMS_Executive service is running on the site server. If it is stopped or is not responding, restart the service.
Verify that the Configuration Manager site database is performing properly.
Determine whether the increased load is due to an infrequent influx of new software inventory records, or whether the file load remains relatively constant. If the load is constant, update the Configuration Manager infrastructure to achieve zero processing backlogs. If the load is due to a large number of newly inventoried computers or recent change of software inventory setting, the issue can resolve itself if there are sufficient resources to process pending files in addition to the standard file load.
Verify that the Configuration Manager site database has sufficient space. If the database is set to autogrow, verify that there is sufficient disk space for the database to expand.
Adjust the frequency of inventory collection to allow for a longer interval for files to be processed.
Plan carefully before modifying the software inventory setting. Conduct performance test to verify that the infrastructure can accommodate the extra load.
Verify that the site server has connectivity to the Configuration Manager site database server.
