Good morning / afternoon!
I have one http check that I am trying to convert from Nagios over to Icinga2
but its kicking my butt. In a nutshell, the way this check works is the icinga
host uses nrpe to run a command on the destination host which, in turn, tries
to verify that that host can reach an outside host (ie icinga —> SERVERNAME —>
amazonaws.com).
The problem that I am coming across is that this check only runs when the nrpe
arguments are encapsulated within quotes, something Icinga can’t process. If I
escape the quotes in the check, the remote host doesn’t like it and returns the
following error:
Client request was invalid, bailing out...
Error: Request contained illegal metachars!
Here is how I have it currently configured...
object CheckCommand "check_http_remote" {
import "nrpe-common"
command = [ PluginDir + "/check_nrpe","-H", "$host.address$", "-t",
"30", "-c", "check_http_remote", "-a", "$ARG1$”]
apply Service "pingS3" {
import "generic-service"
display_name = "pingS3"
check_command = "check_http_remote"
vars += {
"ARG1" = "-H s3.amazonaws.com -u
https://s3.amazonaws.com/blahblahblah.txt";
}
assign where host.vars.servertype in [“remote_server"]
}
...and this is how it is configured in nagios
define command{
command_name check_http_remote
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c
check_http_remote -a "$ARG1$ $ARG2$ $ARG3$ $ARG4$ $ARG5$ $ARG6$ $ARG7$ $ARG8$
$ARG9$ $ARG10$ $ARG11$ $ARG12$ $ARG13$ $ARG14$ $ARG15$ $ARG16$ $ARG17$ $ARG18$
$ARG19$ $ARG20$"
define service {
use generic
service_description pingS3
check_command
check_http_remote!-H!s3.amazonaws.com!-u!https://s3.amazonaws.com/blahblahblah.txt!-t!30
Lastly, here are the results of a manual run from the icinga server, the first
without quotes and the second with.
/usr/lib64/nagios/plugins/check_nrpe -H SERVERNAME -c check_http_remote -t 30
-a -H s3.amazonaws.com -u https://s3.amazonaws.com/blahblahblah.txt
Name or service not known
HTTP CRITICAL - Unable to open TCP socket
/usr/lib64/nagios/plugins/check_nrpe -H SERVERNAME -c check_http_remote -t 30
-a "-H s3.amazonaws.com -u https://s3.amazonaws.com/blahblahblah.txt";
HTTP OK: HTTP/1.1 200 OK - 496 bytes in 0.050 second response time
|time=0.049625s;;;0.000000 size=496B;;;0
Any thoughts on how I can overcome this and still use the same check? I can
code my way out of this by running individual scripts on each server and
calling them from Icinga but that doesn’t seem like the right way of doing it._______________________________________________
