Availability Overview
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
applications. Service-level metrics are automatically evaluated against user-
defined objectives to establish alert priorities when application objectives are not
being met for an application process.
•
Communication line availability for AM3270, ATP6100, Envoy, EnvoyACP, Multilan,
Snax, and X.25 such as percent line busy, Input/Output bytes read and written
InputData/OutputData bytes read and received, and Retries, state of the line are
reported by the COMM SGP.
•
CPU availability, such as percent CPU busy, interrupt busy rates, send busy rates,
queue lengths, dispatches, disk I/O, cache hits, and memory swap rates. State
reporting of CPU up or CPU down is also supplied.
•
Disk availability, such as percent disk busy, percent write busy, percent read busy,
number of disk requests, capacity used, cache hits, queue lengths, and swap rates
are a few of the performance statistics reported by the Disk SGP. State reporting
about down paths to a Disk device, such as the Disk process, is also provided.
•
Expand line-handler availability information, such as packets sent, received, and
passed through; error rate statistics such as block check character errors (BCC),
no buffer failures, and negative acknowledgment rates. State reporting of whether
the Expand line-handler is up, down, or connecting is also provided.
•
Expand end-to-end node availability, such as packets sent/received statistics and
path information for number of hops from one Expand node to another.
•
File availability information including existence, security settings, size, and amount
of space remaining.
•
Process availability information including location, priority, and resource
consumption.
•
ProcessBusy availability information, such as busiest processes, CPU busy
percent per process, messages sent and received, receive queue length, and
average memory pages used, are a few of the performance statistics reported by
the ASAP Monitor.
•
Query monitoring for SQL/MX queries originated from ODBC monitors query start
and end time and various other statistics about the query.
•
User selected Files collects file availability information, such as percent full, EOF,
file code, and file format.
