Global Metric Manager
In this example, the perl expression checks each line of output and
extracts the following values:
498792 /
0 /proc
0 /sys
0 /dev/pts
0 /proc/bus/usb
The Virtual Agent then checks each line of the output and uses the
key index to identify a matching row and returns the appropriate
value.
Note: The Virtual Agent only uses the first two matches it finds. For
example, it uses the first two values in parenthesis, not including
the column delimiters such as (?:\S+\s+).
Configuration Example 2
Using the example above, what happens if the components are
defined as tmpfs and sysfs. the Metric Editor configuration would
be as follows:
Command: /bin/df –a
Perl Expression: /(\S+)\s+([0-9]+)\s+[0-9]+.*\S+\s+(\S+)/
Key Index: 0
The matching output would be:
tmpfs 498792
proc 0
sysfs 0
devpts 0
usbfs 0
Even if the final (\S+) remains in the pattern, it will not be included
in the matches that the Virtual Agent evaluates. In addition, the key
index had to be changed to match the newly defined components.
