Collections and Metrics

The Foglight for DB2 LUW agents collect metrics and store them in the Foglight topology model as topology objects.

CF Locks Collection

Tracks how database members use DB2 pureScale cluster caching facility (CF) locks.


Metric	Description
DATABASE	The name of the monitored database.
MEMBER	The name of the member.
CF_RESPONSE_TIME	Average interconnect network time per CF call calculated over all CF calls.
CF_WAIT_TIME	Time (in milliseconds) spent communicating with the cluster caching facility. Both network time and processing time. This time does not include time spent on granting locks or performing page reclaims.
CF_WAITS	Number of times the database system waited while communicating with the cluster caching facility. This is approximately the number of CF calls.
LOCK_ESCALS	Number of times that locks were escalated from several row locks to a table lock.
LOCK_ESCALS_GLOBAL	Number of lock escalations on a global lock due to global lock memory usage reaching the limit specified in the cf_lock_sz database configuration parameter.
LOCK_TIMEOUTS	Total number of lock timeouts.
LOCK_TIMEOUTS_GLOBAL	Number of lock timeouts where the application holding the lock was on a remote member
LOCK_WAIT_TIME	Total time spent waiting for locks.
LOCK_WAIT_TIME_GLOBAL	Time spent waiting for global locks in milliseconds.
LOCK_WAITS	Total number of locks waits.
LOCK_WAITS_GLOBAL	Number of locks waits due to the application holding the lock on a remote member.
GLOBAL_ESCALS_PERCENTAGE	= LOCK_ESCALS_GLOBAL / LOCK_ESCALS
GLOBAL_LOCK_TIMEOUT_PERCENTAGE	= LOCK_TIMEOUTS_GLOBAL / LOCK_TIMEOUTS
GLOBAL_LOCK_WAIT_TIME_PERCENTAGE	= LOCK_WAIT_TIME_GLOBAL / LOCK_WAIT_TIME
GLOBAL_LOCKS_PERCENTAGE	= LOCK_WAITS_GLOBAL / LOCK_WAITS.

CF Memory Pools Collection

Tracks how hosts use DB2 pureScale cluster caching facility (CF) memory pools.


Metric	Description
HOST_NAME	The name of the monitored host.
HOSTID	The ID of the CF component.
CF_LOCK_MEM_UTILIZATION	CF Lock Pool Utilization
CF_MEM_UTILIZATION	CF Memory Utilization
CF_SCA_MEM_UTILIZATION	CF SCA Pool Utilization
CONFIGURED_CF_GBP_SIZE	Configured Global Buffer Pool Size
CONFIGURED_CF_LOCK_SIZE	Configured Lock Memory Size
CONFIGURED_CF_MEM_SIZE	Configured CF Memory Size
CONFIGURED_CF_SCA_SIZE	Configured SCA Memory Size
CURRENT_CF_GBP_SIZE	Current Global Buffer Pool Size
CURRENT_CF_LOCK_SIZE	Current Lock Memory Size
CURRENT_CF_MEM_SIZE	Current Total CF Memory Size
CURRENT_CF_NONALLOCATED_SIZE	Current amount of memory allocated for the CF but not used for the GBP, LOCK, or SCA pools.
CURRENT_CF_SCA_SIZE	Current SCA Memory Size
GBP_UTILIZATION	Global Buffer Pool Utilization

CF Resource Usage Collection

Tracks how instances use DB2 pureScale cluster caching facility (CF) resources.


Metric	Description
INSTANCE	The name of the monitored instance.
ID	The ID of the CF component.
HOST	The name of the machine that hosts the CF component.
CPU_USAGE_TOTAL	Percentage of overall CPU usage of the CF machine.
MEMORY_FREE	Amount of free physical memory (MB).
MEMORY_SWAP_FREE	Amount of free swap space (MB).
MEMORY_SWAP_TOTAL	Total amount of swap space (MB).
MEMORY_TOTAL	Total size of physical memory (MB).
MEMORY_UTILIZATION	The percentage of free memory out of the total memory assigned to the CF machine.
VIRTUAL_MEMORY_FREE	Amount of reserved virtual memory.
VIRTUAL_MEMORY_TOTAL	Total amount of virtual memory on the system (MB).
