This utility is designed to be called by the ARGx parameters of a Nagios configuration as one of the following:
\$\$(\$USER1\$/env [-n <var>] [-t <default>] [-f <field>] [-d <delim>] [-s <val>] [-u|-l] [-H|-S|-C <suffix>] [-v]
\$\$(\$USER1\$/env -N [-H suffix]
\$\$(\$USER1\$/env [-n <var>] [-t <default>] [-f|-F <field>] [-d <delim>] [-s <val>] [-u|-l] [-H|-S|-C <suffix>] [-v]
\$\$(\$USER1\$/env -N [-NP] [-H suffix]
Where:
var the name of a case-insensitive NAGIOS_variable (defaults to "servicedesc")
default a default value if \$NAGIOS_var\$ is blank (case sensitive)
field an awk-compatible field number (potentially to use with <delim>)
field an awk-compatible field number (potentially to use with <delim>) (see below)
delim an awk-compatible field delimiter (defaults to space and colon)
-u Convert the output to uppercase
-l Convert the output to lowercase
-p Convert / to | (mainly for disk names in NCPA checks)
suffix Take var result and use the it to get NAGIOS__[HOST|SERVICE|CONTACT]<result><suffix>
-v Be verbose (only for debugging)
-s The result must match this value or else it will return blank
--num The result will have all non-numbers stripped from it
-NP Returns NAGIOS__HOSTNCPAPORT (implied default of 5693)
-N Look for NAGIOS__HOSTNCPA<suffix> (defaults to TOKEN)
Can do double lookup if -H is specified directly: -H TOKEN will find NAGIOS__HOSTNCPATOKEN=Level1 which then finds NAGIOS__HOSTLEVEL1TOKEN=Secret
Or -H PASS will find NAGIOS__HOSTNCPAPASS=Level2 which will then find NAGIOS__HOSTLEVEL2PASS=SuperSecret
@@ -44,8 +47,9 @@ Where:
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 as follows, unless the field starts with a negative, in which case it will read from the last word forward:
echo \$NAGIOS_var\$ | awk -F <delim> '{print $<field>}'
If -F is used, -d is forced to " " and the field number reflects is the first, second, or third of the last three fields
Ex: Disk check on / 80 90 With -F 1=/, -F 2=80, -F 3=90
