Hi,

and please see the below result for Nagios Root

[root@nms libexec]# ./check_em01.pl 10.x.x.x --type=temp --temp=65/75,60/80
Unable to read sensor

[rkennedy]

What version of the wizard are you running? I just checked on my system, and it created a file called check_em01.pl with the command definition as below -

Code: Select all

check_em01_light 	$USER1$/check_em01.pl --type=illum --illum=$ARG1$,$ARG2$ $HOSTADDRESS$

It looks like the file you were attempting was check_em08, so just trying to see if something is invalid. As for this, please try running it with --debug appended -

Code: Select all

./check_em01.pl 10.x.x.x --type=temp --temp=65/75,60/80 --debug

Then post back the result for us.

Hi,

please see the below result after applied the commands

[root@nms libexec]# ./check_em01.pl 10.x.x.x --type=temp --temp=65/75,60/80 --debug
connected to 10.x.x.x:80
timeout(alarm) during sensor read
Unable to read sensor

What version of the wizard are you running? how can do that ?

[lmiltchev]

Did you enable the plugin by running the following command from the command line:

Code: Select all

gcc /usr/local/nagiosxi/html/includes/configwizards/esensors-websensor/plugins/check_em08.c -o /usr/local/nagios/libexec/check_em08

as described in our documentation?

[bashar.abed]

Hi,

when I applied this command ,i saw this message
gcc /usr/local/nagiosxi/html/includes/configwizards/esensors-websensor/plugins/check_em08.c -o /usr/local/nagios/libexec/check_em08

[nagios@nms. ~]# /usr/local/nagios/libexec/check_em08 10.x.x.x H 15 80 10 90
Invalid data received.

[rkennedy]

Based on what the plugin is doing, it appears to be looking at index.html -

Code: Select all

       print $remote "GET /index.html?em345678 HTTP/1.1 \r\n";

Let's take a look at what's being seen. Please run the following -

Code: Select all

curl 10.x.x.x/idnex.html?em345678 -v

(replace 10.x.x.x with the proper IP)

Then post this back here for us to look at.

[bashar.abed]

Hi,

after applied this commands the result is

curl 10.x.x.x/idnex.html?em345678 -v

[root@nms ~]# curl 10.x.x.x/idnex.html?em345678 -v
* About to connect() to proxy 10.y.x.x port 8080 (#0)
* Trying 10.y.x.x... Connection timed out
* couldn't connect to host
* Closing connection #0
curl: (7) couldn't connect to host

the proxy IP is incorrect, how can change it to correct one

[rkennedy]

That's most likely the issue. Take a look at this article which should help to resolve the proxy - https://support.nagios.com/kb/article.php?id=147
