This utility is designed to be called by the ARGx parameters of a Nagios configuration as follows:
|
|
|
|
\$\$(\$USER1\$/env -n <var> [-t <default>] [-f <field>] [-d <delim>]
|
|
|
|
Where:
|
|
|
|
var is the name of a NAGIOS_variable (see https://assets.nagios.com/downloads/nagioscore/docs/nagioscore/4/en/macrolist.html) (case insensitive)
|
|
default is a default value if \$NAGIOS_var\$ is blank (case sensitive)
|
|
word is an awk-compatible field number (potentially to use with <delim>)
|
|
delim is an awk-compatible field delimiter (defaults to space)
|
|
|
|
The value will always be trimmed of leading and/or trailing spaces/tabs.
|
|
|
|
If -f is used, then the result will be as if the request were:
|
|
|
|
eche \$NAGIOS_var\$ | awk -F <delim> '{print $<field>}'
|
|
|
|
Examples:
|
|
|
|
.../env -n servicedesc
|
|
Will return "Root Partition" (or whatever the service check is named)
|
|
.../env -n hostName
|
|
Will return "localhost" (or whatever the name of the host is that ran the check)
|
|
.../env -n SERVICESTATE -t 0
|
|
Will return the current state of the service (0, 1, 2) or 0 if the state is not defined
|
|
.../env -n servicedesc -d : -f 2
|
|
If the service name is "MySQL Check: myDatabase" then it will return "myDatabase" (trimmed)
