 The Rollover option renames entity database files daily so you can archive
them for historic analysis at a later date.
Once started, ASAP needs no operator intervention. Even when CPUs become
unavailable, the ASAP database is automatically maintained.
Collection
The Database Collector is a process pair that collects application and system
availability information from system nodes throughout the network. Availability
information records from remote monitors and SGPs throughout the network are
received by the ASAP Collector process, which stores the data in the normalized
ASAP database.
User-defined partitions let multiple volumes share the I/O workload.
Node Monitors
Each monitored node in the network has a Monitor process pair running in it. The
Monitor starts individual SGPs based on user criteria for each SGP. If the SGP CPU
becomes unavailable after starting, the monitor restarts the SGP in an available CPU.
Statistics Gathering Processes
Each CPU on the monitored node has at least one Statistics Gathering Process (SGP)
executing in it provided that monitoring is turned on, or auto discovery was used. This
SGP process determines CPU availability and busiest Process information and then
sends these availability records to the Collector process. When at least one CPU on
the node is monitored, system availability information is collected. System availability is
the average availability statistics for all monitored CPUs on the node.
Application Statistics Gathering Process
The application SGP collects customer application service-level metrics from
application monitor processes for tracking productivity, performance, and availability of
the applications. These service-level metrics are automatically evaluated against
predefined objectives for establishing alert priorities, letting system operators and
administrators quickly identify service-level issues that are not meeting the defined
objectives for an application process. This SGP, the ASAPX Monitor processes, the
ASAPX CI, and the ASAPX Library are all part of the optional product ASAPX.
CIP Statistics Gathering Process
CIP SGPs collect availability information on Cluster I/O Module (CLIM) devices on
NonStop servers. The CIP SGP collects status and statistics information for CLIM
devices, CIP Monitor processes and CIP Provider processes. It uses several
