OneSight Administrator Guide

Modifying System Definitions
Perl Expression – Enter a Perl expression if you want to further
qualify the results returned by the discovery request. Refer to
Using Regular Expressions for Pattern Matching in Chapter 5
for more information about regular expressions.
The following option is available on the SNMP tab for individual
components.
Search for string – This field is automatically filled in as a result
of discovery based on the Object ID and Perl expression that
were entered.
UNIX System Tab – The UNIX System tab is used when configuring
monitors to collect data on UNIX workstations. If the machine you
are configuring as a monitored system is not a UNIX machine, this
tab is unnecessary.
For help installing the UNIX Remote Agent, see Installing the UNIX
Remote Agent in Chapter 2.
Instance – When configuring a UNIX profile, enter the system
disk information using the module.machine.name format. This
information can be gathered using a UNIX kernel statistics utility
(for example, kstat). For example: sd.0.sd0
To configure multiple disk instances, highlight the Disk type and
click Add.
For more information about how to collect statistics using UNIX
system utilities, see the Knowledgebase section on the OneSight
Support web page.
Virtual Agent Tab – This tab is necessary when you are using a
virtual agent metric and you apply a profile that makes use of the
component.
Instance – Enter the component that you want to monitor.
