FCM Activity Collection

The following table provides a list of the FCM Activity metrics that are collected, and a description for each.


Metric	Description
DB_NAME	The name of the monitored database.
DBPARTITIONNUM	The database partition from which the data was retrieved for this row.
CONNECTION_STATUS	This interface returns a text identifier, based on the definition in sqlmon.h, which is one of the following values: INACTIVE ACTIVE CONGESTED
CONNECTION_AVAILABILITY	The agent's connection FCM availability. Possible values are either 0 (INACTIVE or CONGESTED) or 100 (ACTIVE).
FCM_DBPARTITIONNUM	The database partition number to which data was sent or from which data was received (as per the TOTAL_BUFFERS_SENT and TOTAL_BUFFERS_RCVD columns).
TOTAL_BUFFERS_SENT	The total number of FCM buffers sent from the current node to the remote node. High values of this metric can indicate the need to redistribute the database or to move tables to reduce the inter-node traffic.
TOTAL_BUFFERS_RCVD	The total number of FCM buffers received by the node issuing the GET SNAPSHOT command, from the node identified by the NODE_NUMBER (see the db2nodes.cfg file). You can use this element to measure the level of traffic between the current node and the remote node. If the total number of FCM buffers received from this node is high, you may want to redistribute the database or move tables to reduce the inter-node traffic.
TOTAL_BUFFERS_SENT_RATE	The rate of the total number of FCM buffer pages sent from the current node to the remote node. This parameter can be used for measuring the level of traffic between the current and remote nodes. High inter-node traffic can be addressed by redistributing the database or moving tables to reduce the inter-node traffic.
TOTAL_BUFFERS_RCVD_RATE	The rate of the total number of FCM buffer pages received by the current node from the remote node. This parameter can be used for measuring the level of traffic between the current and remote nodes. High inter-node traffic can be addressed by redistributing the database or moving tables to reduce the inter-node traffic.

FS DB Storage Collection

The following table provides a list of the FS Database Storage metrics that are collected, and a description for each.


Metric	Description
DB_NAME	The name of the monitored database.
FS_ID	This element shows the unique identification number provided by the operating system for a file system pointed to by a storage path.
FS_TOTAL_SIZE	This element shows the capacity (MB) of a file system pointed to by a storage path.
FS_USED_SIZE	This element shows the amount of space (MB) already used on a file system pointed to by a storage path.
STO_PATH_FREE_SIZE	This element shows the amount of free space (MB) available on a file system pointed to by a storage path. If multiple storage paths point to the same file system, the free size is not divided among them.

FS DB Storage Summary Collection

The following table provides a list of the FS Database Storage Summary metrics that are collected, and a description for each.


Metric	Description
OVERALL_FS_TOTAL_SIZE	This element shows the capacity (MB) per database of a file system pointed to by a storage path.
OVERALL_FS_USED_SIZE	This element shows the amount of space (MB) per database already used on a file system pointed to by a storage path.
OVERALL_STO_PATH_FREE_SIZE	This element shows the amount of free space (MB) per database available on a file system pointed to by a storage path. If multiple storage paths point to the same file system, the free size is not divided among them.
OVERALL_DB_FS_UTILIZATION	This element shows the amount of used space (MB) per database available on a file system pointed to by a storage path.

FS Instance Storage Collection

The following table provides a list of the FS Instance Storage metrics that are collected, and a description for each.


Metric	Description
OVERALL_FS_TOTAL_SIZE	The overall total space size (MB) of file systems over which the DB2 instance is spread.
OVERALL_FS_USED_SIZE	The amount of space (MB) used on the file systems over which the DB2 instance is spread (not just what DB2 is using; this metric represents the overall usage).
OVERALL_INSTANCE_FS_UTILIZATION	The overall utilization (%) of the file systems over which the DB2 instance is spread.
OVERALL_FREE_SIZE	This element shows the amount of free space (MB) per instance on a file system.
