ASAP 3.2 Server Manual

HP NonStop ASAP Server Manual Page 66 of 381
When the ASAP Conversational Interface (CI) starts a remote ASAP Monitor process,
the Monitor starts various monitoring functions specified in the ASAPCONF file or from
interactive user commands. The ASAP Monitor is responsible for starting and
maintaining the proper monitoring software in its node. If any Monitor or Statistics
Gathering process (SGP) goes down for any reason, the ASAP Monitor in that node
coordinates an automatic restart of processes as needed. For example, if a CPU fails
and comes back online, the CPU SGP for that CPU is restarted. Or, if a remote ASAP
Monitor process fails, its backup process takes over since the ASAP Monitor process
is continuous.
The remote ASAP Monitor starts the CPU SGP in each CPU of the monitored node.
CPU SGPs are responsible for gathering CPU-level statistics, including CPU
performance metrics, Operational state, and information about the busiest processes
in their CPU. The CPU SGPs report CPU-level information to the ASAP Monitor
process. The Monitor bundles this information into a single message and forwards it to
the ASAP Collect process on the main Collection node. The Collect process parses
this information and stores it in the normalized ASAP database. The data can be
displayed with the ASAP CPU and PROCESSBUSY commands, or with various block-
mode or workstation programs.
ASAPNCP Object File
The ASAP Monitor starts the Node SGP on its node if the Node SGP is enabled. The
ASAP Statistics Gathering (ASAPNCP) Process collects statistics for the Expand end-
to-end node statistics. The statistics gathered are path information statistics and traffic
statistics between two Expand nodes. ASAPNCP communicates directly with the
Expand Manager process to obtain raw counters. For a complete list of node
availability counters, see the NODE Command.
The Node SGP does not support monitoring or Discrete Objectives Thresholds
(DOTs).
ASAPPRO Object File
The ASAP Monitor starts the Process SGP on its node if Process is enabled. The
ASAP Statistics Gathering (ASAPPRO) Process collects availability information for the
user-selected processes. The utilization counters gathered include process busy time,
process queue length, and process wait time. The Process SGP gets availability
information through the Guardian API. For a complete list of Process availability
counters, see the PROCESS Command.
ASAPRDF Object File
The ASAP Monitor starts the RDF SGP on its node if RDF is enabled. The ASAP
Statistics Gathering (ASAPRDF) process collects availability information for the RDF
updater or RDF extractor. The utilization counters gathered include relative time delay,
