PMQ

The statistics in this category summarize activity in persistent message queues.

Note: Starting with CIC 2017 R1, the "PMQ is persisted to disk" and the "oldest message on disk" statistics now report the actual number of PMQ files present in the filesystem. These statistics are updated every 60 seconds.

IP is connected to DB

Indicates whether or not Interaction Processor's PMQ object currently has a connection to the database.  Not having a connection only indicates an error if items are also being persisted to disk.

IP Server is connected to DB

Indicates whether or not IP Server's PMQ object currently has a connection to the database.  Not having a connection only indicates an error if items are also being persisted to disk.

Admin Server is connected to DB

Indicates whether or not Admin Server's PMQ object currently has a connection to the database.  Not having a connection only indicates an error if items are also being persisted to disk.

Stat Server is connected to DB

Indicates whether or not Stat Server's PMQ object currently has a connection to the database.  Not having a connection only indicates an error if items are also being persisted to disk.

Recorder server is connected to DB

Indicates whether or not Recorder Server's PMQ object currently has a connection to the database. Not having a connection only indicates an error if items are also being persisted to disk.

IP's PMQ is persisted to disk

Indicates that PMQ is currently buffering Interaction Processor messages to disk.  This is a common occurrence for Stat Server since it periodically sends large amounts of data to the database.  If the subsystem is connected to the database, and it has messages persisting to disk then you should examine the 'oldest message on disk' statistic to find out whether messages are flowing smoothly or are backed up.

IP Server's PMQ is persisted to disk

Indicates that PMQ is currently buffering IP Server messages to disk.  This is a common occurrence for Stat Server since it periodically sends large amounts of data to the database.  If the subsystem is connected to the database, and it has messages persisting to disk then you should examine the 'oldest message on disk' statistic to find out whether messages are flowing smoothly or are backed up.

Admin Server's PMQ is persisted to disk

Indicates that PMQ is currently buffering Admin Server messages to disk.  This is a common occurrence for Stat Server since it periodically sends large amounts of data to the database.  If the subsystem is connected to the database, and it has messages persisting to disk then you should examine the 'oldest message on disk' statistic to find out whether messages are flowing smoothly or are backed up.

Stat Server's PMQ is persisted to disk

Number of Stat Server PMQ objects that are currently persisted to disk.

Recorder Server's PMQ is persisted to disk

Number of Recorder Server PMQ objects that are currently persisted to disk.

IP's oldest message on disk

This statistic indicates the age of the oldest message that PMQ is currently storing to disk for Interaction Processor server.  This operation is common for Interaction Processor server, and should be a concern only if the time lag is larger than the default reporting period (30 minutes).

IP Server's oldest message on disk

Age of the oldest message that PMQ is currently storing to disk for Interaction Processor server.  This operation is common for Interaction Processor server, and should be a concern only if the time lag is larger than the default reporting period (30 minutes).

Admin Server's oldest message on disk

Age of the oldest message that PMQ is currently storing to disk for Admin Server.  This operation is common for Admin Server, and should be a concern only if the time lag is larger than the default reporting period (30 minutes).

Stat Server's oldest message on disk

Age of the oldest message that PMQ is currently storing to disk for Stat Server.  This operation is common for Stat Server, and should be a concern only if the time lag is larger than the default reporting period (30 minutes).

Recorder Server's oldest message on disk

Age of oldest message that PMQ is currently storing to disk for Recorder Server. This operation is common for Recorder Server, and should be a concern only if the time lag is larger than the default reporting period (30 minutes).

Recorder Server errors persisted to disk

Number of Recorder Server error objects that are currently persisted to disk.

Recorder Server's oldest error on disk

Age of the oldest error that Record Server is currently storing to disk.
