Nagios Support Forum

Hello,

I just got my NagiosXI trial copy up and running (I'm on a stand alone system) and I'm
trying to monitor a switch. Here is the command and the error I got along with the
output as suggested in "Step 2" of the configuration wizard. Any help would be greatly
appreciated.

Thank you.

What's the output of snmpwalk -c public -v 3 192.168.17.112?

If that gives an obvious error, can you also provide the output of snmpwalk -c public -v 2c 192.168.17.112?

Thanks!

Please install the following Perl module via yum install perl-Crypt-Rijndael -y

Run through the configuration wizard again and report any errors. Thanks!

>>Please install the following Perl module via yum install perl-Crypt-Rijndael -y
I'm on a stand alone so can't use yum.
Couldn't find the rpm on the Rhel site, found the following on rpmfind.net:
perl-Crypto-Rijndael-1.09-2.el6.x86_64.rpm
When I do the install it says its already there, but it wasn't. I checked first.
When I re-ran ./fullinstall, from a fresh restore of the system, the only odd things
I noticed are:
This system is not registered...
chown: cannot access '/etc/openldap/cacerts': No such file or directory
/bin/chmod: <same>

The snmpwalk commands no change.
However, I tried the following and it works:
./check_snmp -H 192.168.17.112 -P 3 -U usrname -L authNoPriv -A myPasswrd -o ifOperStatus.10001 -r1
I get SNMP OK - up(1)

Thanks.

Also,
I just brought nagiosxi up and I get two Notices:
Update Check Failed. ( not internet )
System Status Degraded!
One or more critical components have been stopped, is disabled or malfunctioned...

Was this system one built using our offline installer, or is it a regular install you pulled the plug on?

Also, can you PM me your Profile? You can download it by going to Admin > System Config > System Profile and click the Download Profile button towards the top. If for whatever reason you *cannot* download the profile, please put the output of View System Info (5.3.4+, Show Profile if older) in the thread (that will at least get us some info).

After you PM the profile, please update this thread. Updating this thread is the only way for it to show back up on our dashboard.

UPDATE: Profile received and shared with techs.

I can't tell if you got my PM.

The offline install requires access to some repos. In that vein, what's the output of yum repolist?

Also, the version you are running has security vulnerabilities which have been fixed in http://repo.nagios.com/nagiosxi-offline ... _64.tar.gz

I'd suggest upgrading before you get too far into your trial. That said, with the offline install, you are already protected from certain types of attacks.

Ok, things are improving.
I have no idea how my switch node started working, but it did so I must have corrected something inadvertently.
I also discovered where to put custom .cfg's. I have a build with nagios core so I copied one of my client configs there and it seems to be working ok.

One thing that I haven't figured out yet is why some "hosts" show up in My Views >> Service Detail, and others don't. Any ideas?

Anyway, thanks for your response.
