TACL Monitoring Macros
TACL Monitoring Macros
TACL macros can be developed to run as object monitoring tools. Executed on a
scheduled basis, TACL macros can inform operators of potential problems such as a
stopped process, a disk or file becoming full, or a transaction running too long.
Refer to Section 6, Automating Operations and Recovery Procedures,” for an example
of a TACL macro that can be used to warm start a drained spooler.
Tandem Network Statistics Extended (NSX)
NSX is a NonStop operating system network performance monitor that collects and
displays processor, process, and Expand process statistics from other NonStop systems
operating in a Tandem network.
NSX monitors and reports high-level, real-time network statistics from multiple network
nodes to one or more locations within that network. In addition, NSX collects and
reports on the busiest processes in each processor in all monitored systems.
Process statistics are automatically gathered for the programs that are consuming the
most processor time, are sorted by processor usage, and are forwarded by NSX monitors
so that this information can be displayed in several different ways.
All NSX statistics are stored in the NSX database for historic reference, as well as for
shared access by multiple users and applications.
Network Statistics
NSX provides a high-level, network-wide view of major system component
performance. NSX measures the following performance entities:
Processor statistics, such as
Processor busy
Interrupt busy rates
Send busy rates
Queue lengths
Dispatches
Disk I/Os
Cache hits
Memory swap rates
Expand process statistics, such as
Packets sent, received, and passed through.
Error rate statistics, such as block-check character (BCC) errors, no-buffer
failures, and negative acknowledgment rates.
Note. TACL macros do not run in NonStop mode, so they might not be as reliable as OMF.
