OneSight Administrator Guide

Global Metric Manager
checks the last entry whenever the log file changes. This returned
data can then be used within OneSight, both for alerting, using
threshold alerts, and reporting.
To check if the file exists, use the File/directory exists metric type
and leave this field blank.
String Mappings – Displays the String Mappings dialog box for
specifying string mappings.
String Mappings – OneSight collects numeric performance data. If
you are measuring a log file response that is a string, it can be
converted to a number for use in OneSight by using the String
Mappings field. Simply specify a semicolon delimited mapping
of Strings to Integers. For example, ―false=0;true=1‖; will
convert a ―false‖ reading to a 0 value in OneSight, and this will
be displayed in OneSight Status as ―false=0‖. If you only want to
display the string on the OneSight status page, use a colon, rather
than a semi-colon to delimit the values.
If you neglect to provide a mapping for a specific string,
OneSight will consider this a Sample Failure, and report the
String that was returned. String Mappings can also be used to
translate a number to a String for display in OneSight Status.
This is helpful when numbers represent an objects state.
Note that string matching is case-insensitive and data that has a
colon cannot be used in string mapping.
Sample Continuously – Select to sample continuously. This field is
only available when Metric Type is Perl Expression value.
Alert Collection Mode – Select how you want alerts to be processed.
Report Alerts as they Occur – If multiple alerts occur on the same
trigger they are all sent. Alerts with the same timestamp as a
previous alert will not be sent.
