Nagios core check: Is it possible to pipe sort -u in a check command? -


is possible |sort -u in check command?

#check_active_node define command{     command_name    check_active_node_list     command_line    /usr/lib/nagios/plugins/check_active_node.sh '$arg1$' '$arg2$'|sort -u

normally no. pipe character "|" not allowed part of line being executed nagios - there important security reasons this. there ways around it, i'd not recommend using of them. best solution modify plugin (create check_active_node_custom.sh , edit that), , add ever sorting need script itself. remember nagios system expects return codes , text plugin, , should still function expected after edits.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
