Nagios Support Forum

Looks like I got it working a bit better, but those sterr I am seeing is probably related to web inject not being installed on this new server. Is there an easy way to run the install for webinject?

I ran through the perl dependencies and installed them ... I see this error in the log a bunch now:

^G[1384286574] SERVICE ALERT: p021_node02;client1207;CRITICAL;SOFT;2;(No output on stdout) stderr: Can't locate Crypt/SSLeay.pm in @INC (@INC contains: /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/5.8.8 .) at /usr/lib/perl5/site_perl/5.8.8/Webinject.pm line 29.

Looks like you are missing the Crypt::SSLeay dependencies, please run:

okay, now I see:

ran: yum install perl-XML-Parser

now I see a lot of:

Can you show us the xml config for webinject and one of the failing webinject checks from the cli?

/nagios.xml might be referring to the test case file. Check your config.xml and look for this tag:

<testcasefile></testcasefile>

Mine for example is <testcasefile>testcase.xml</testcasefile>
testcase.xml is located in the same directory as the rest of the Nagios Plugins, to include check_webinject (/usr/local/nagios/libexec) I use Ubuntu.

From the command line I call a web service like so:

sudo ./check_webinject -s baseurl=http://url/ testcase.xml

all my nagios.xml file says is:

<globaltimeout>20</globaltimeout>
<reporttype>nagios</reporttype>

located in:

/usr/local/nagios/libexec/webinject

this is how it is on my old nagios as well, which is not throwing the error.

I ran a test:

./check_webinject -s baseurl=client1261.xxxxxxx.com webinject/401prod.xml

but get:

I wonder if the way to reference the bsae_url has changed in the new version?
