ConfigMgr 2007 Perf Threshold: Site Server Inbox schedule.box\requests Backlog > 10,000 over 3 hours

Summary

The total number of files that are in the Scheduler's schedule.box\requests inbox on the site server has exceeded the standard operational threshold.

This folder temporarily stores the initial send request files (.srq) before the Scheduler transfers the files to a sender. This folder also stores send request files that are returned when the sender cannot connect to the target site.

This condition increases unless it is resolved. If the file count continues beyond the threshold, sending jobs to parent and child sites is delayed, resulting in replicated information not being reflected in the Configuration Manager site databases of those sites in a timely manner. Configuration Manager objects and reports might not accurately represent the state of the parent or child sites.

Causes

The total number of files can exceed the threshold because:

• The Configuration Manager Scheduler component is stopped or not responding.

• The Configuration Manager Scheduler could be processing other outbound jobs.

• The site server has insufficient resources, such as CPU, memory, or disk space.

• An event has occurred that requires the replication of a large amount of data.

• The site server might have lost connectivity to the Configuration Manager site database server.

• The Scheduler is experiencing problems creating the package to send, or the package is corrupted.

• The sender selected by Scheduler cannot connect to the target site.

• The sender selected by Scheduler is experiencing sending errors to the target site.

Additional

If this alert is generating too many false positives, you can modify the threshold tab of the rule properties to designate values that are more appropriate for your environment.

To view a graph that plots the backlog trend for this inbox on site servers:

• In the Operations Manager Monitoring console, navigate to Monitoring > Microsoft System Center Configuration Manager 2007 > Performance > Backlogs > Site Servers.

• Click Inbox schedule.box/requests Backlog in the last 48 hours.

Backlog trending does not appear on the graph unless the corresponding performance measure is enabled first. To enable the performance measure for schedule.box\requests backlog:

• In the Operations Manager Authoring console, navigate to Authoring > Management Pack Objects > Rules.

• In the Rules pane, search for ConfigMgr 2007 Perf Measure: Site Server Inbox schedule.box\requests Backlog.

• Right-click the rule and navigate Overides > Override the Rule and then click For all objects of type: Microsoft ConfigMgr 2007 Site Servers.

• Select the Enabled checkbox and then set the Override Setting to True. Click OK.

Related Events:

You can also look for alerts that relate to the Scheduler component not responding or to the site server having insufficient resources, such as CPU or memory. These alerts are the potential cause of Scheduler problems. Depending on the cause, it is likely that other types of backlogs (hardware inventory, software inventory, software metering) on the site server are also increasing and corresponding alerts are occurring.

This alert is best handled by Configuration Manager administrators.
