System Info
Linux Distribution and version?
*Linux version 2.6.18-348.16.1.el5PAE #1 SMP Wed Aug 21 04:49:45 EDT 2013 i686 i686 i386 GNU/Linux
CentOS release 5.7 (Final)
32 or 64bit?
32 bit
VMware Image or Manual Install of XI?
VMware Image
Are there specials configurations on your system, ie; is Gnome installed? Are you using a proxy? Are you using SSL?
Forced SSL on NagiosXi login web screen
Nagios Xi version: Nagios XI 2012R2.4
Issue:
I followed the instructions on Passive Monitoring with NRDS found in
but we are not able to get passed this point:
1. cd /tmp
2. wget -O test_server.tar.gz "https://<nagiosxi_server>/nrdp/?cmd=nrdsgetclient&token=<token>&configname=<test_server>"
this only returns a file of 18k (which is the 18 characters of "NO REQUEST HANDLER" when I place that URL https://<nagiosxi_server>/nrdp/?cmd=nrdsgetclient&token=<token>&configname=<test_server> into a web browser)
3. gunzip -c test_server.tar.gz | tar xf -
gzip: test_server.tar.gz: not in gzip format
tar: This does not look like a tar archive
tar: Exiting with failure status due to previous errors
I remove the "-" from the end of the command and I receive the following:
tar: Old option `f' requires an argument.
Try `tar --help' or `tar --usage' for more information.
Our goal is to create a passive check were a command will run every 5 minutes on a remote server which will send the necessary info to NagiosXi

I ran the tail, but don't seem to get any data pertaining to the url call:

Are we looking at the same document? Those commands do not show up in the one you linked. Also, are you making sure to replace the <nagiosxi_server> string with the server's IP address, along with all other such replacements?

Those instructions are from the NRDS Config Manager:
nrds config manager.jpeg
nrds config manager.jpeg
And yes, I am making sure the IP address is correct on the url, I just added those fields in < > to not show sensitive data on this forum.

ecarrasq,
can you confirm the config exists, and the client install files exist, and what are the file permissions are on the NagiosXI machine.
Code: Select all
ll /usr/local/nrdp/configs/
ll /usr/local/nrdp/clients

If I had to guess, it looks like your client doesn't know how to reach the NRDP address you have specified.
Can you run the following from the client replacing <nagiosxi_server> with the exact line you have in the screenshot above and display the output.
Code: Select all
curl https://<nagiosxi_server>/nrdp/

Did you create your config under the NRDS Config Manager prior to switching to SSL or after that? Can you access:
URL, enter your token and submit a command?

I had to do curl with the --insecure as we have a self sign cert. Below is the output:
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>301 Moved Permanently</title>
</head><body>
<h1>Moved Permanently</h1>
<p>The document has moved <a href="https://<nagiosxi_server>/nrdp/">here</a>.</p>
<hr>
<address>Apache/2.2.3 (CentOS) Server at <nagiosxi_server> Port 443</address>
</body></html>
<nagiosxi_server> = I replaced this text with the actual Nagios Xi server's IP address
