ASAP 3.2 Server Manual

ASAP availability information is stored in the ASAP database for historic reference, as
well as for shared access by multiple users and applications. The ASAP Server
collects data with a set of CPU Monitors, Statistic Gathering processes (SGPs), and
Collection processes in a network of systems. ASAP monitors operational information
of system and user-defined resources. The ASAP SGPs report on performance and
operational information of system and user application resources. This information is
collected at defined intervals and forwarded to a Collection process residing on the
same or another node in the network. The Collection process maintains this
information in the ASAP database.
You can configure ASAP to gather performance and state information from multiple
nodes throughout the network. You can independently configure these nodes so some
nodes monitor Disk availability while other nodes do not. You can centralize data
collection to a single node, to groups of regional nodes, or completely distribute it so
each node in a network has its own ASAP availability database.
ASAP lets you monitor individual objects, by defining such objects with the MONITOR
command.
For example, in a 10 processor node, all ASAP SGPs let you get availability
information from all 10 CPUs or just from a few of them. You can separately set
individual thresholds for each object, such as CPU 0 can report EMS events to alert an
operator when the CPU is 45% busy, and send an alert if CPU 0 is less than 25%
busy. Meanwhile, you can set other individual thresholds for CPU 1 and all remaining
CPUs on the node.
ASAP also maintains time synchronization of nodes. You can configure it to
synchronize time daily at a specific interval. Remote node times are synchronized with
the Collection node.
The Collection process automatically creates and maintains the ASAP database files.
You can configure database maintenance options to automatically release files, purge
data, maintain a moving window of data over time, or turn off collection for a selected
period of time.
The ASAP database is a real-time structured database, organized so that the most
current network availability information is immediately available. If you need direct
programmatic access to the ASAP database, see the record description of each ASAP
entity in Appendix B, Appendix B: ASAP Data Definitions.
Availability Overview
The ASAP Server collects state and performance information for System and
Application entities. ASAP entities that report on performance and state information
include:
 Application domain statistics (through the optional ASAPX and ASAPH products)
track the productivity, performance, and availability of customer-developed
