Okay, so you have the tables, which is good.

I'd like you to run this on the terminal, to see whether one of the previous commands worked:

Code: Select all

echo "select * from xi_cmp_trapdata_log;" | mysql -pnagiosxi nagiosxi

The SNMP Trap Interface in Nagios XI does expect net_snmp_perl to be enabled, so at least some functionality won't be there if it's not included. I was able to confirm that the One-Click Systems Test does fail at stage 4 if it's disabled. You do have net_snmp_perl installed, which is the correct package, but there's a chance that some other perl module is creating a conflict with it. I'd also like you to run

Code: Select all

find / -type f -name "SNMP.pm"

so that we can see what else exists with that name.

What we'll want to do is change the second and third of these so that perl doesn't try to read the module:

Code: Select all

mv /usr/share/perl5/vendor_perl/Net/SNMP.pm /usr/share/perl5/vendor_perl/Net/SNMP.pm.bak
mv /usr/local/lib64/perl5/SNMP.pm /usr/local/lib64/perl5/SNMP.pm.bak

Then try to restart snmptt again

[bosecorp]

same error from the GUI

[scottwilkerson]

I forgot to mention after doing this I'd like you to edit /etc/snmp/snmptt.ini

and set this back to 1

Code: Select all

net_snmp_perl_enable = 1

Then restart snmptt

[bosecorp]

the move command created thousands of alerts

(No output on stdout) stderr: Can't locate Net/SNMP.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/local/nagios/libexec/check_

I need to revert that. made the problem worse

[cdienger]

There are a couple modules that use the name net snmp which I think is causing some confusion here. I believe what you need to do to get the right one is:

yum cpan
perl -MCPAN -e shell
install Net::SNMP

[bosecorp]

Ok, some progress here

I did the move command again. Saw thousands of alerts again. but then ran the CPAN commands. that took care of the PERL alerts, but also fixed the issue with not being able to start snmptt with Perl enable.

but I still get that error from the GUI when I run the test

[tgriep]

That error when running the test should be fixed in the next release of XI only if the Nagios server is using Postgres for the nagiosxi database.
If you look in the /usr/local/nagiosxi/html/config.inc.php file

You should see this

Code: Select all

$cfg['db_info'] = array(
    "nagiosxi" => array(
        "dbtype" => 'pgsql',
        "dbserver" => '',
        "user" => 'nagiosxi',
        "pwd" => 'n@gweb',
        "db" => 'nagiosxi',
        "dbmaint" => array( // variables affecting maintenance of db
            "max_auditlog_age" => 30, // max time (in DAYS) to keep audit log entries
            "max_commands_age" => 480, // max time (minutes) to keep commands
            "max_events_age" => 480, // max time (minutes) to keep events
            "optimize_interval" => 60, // time (in minutes) between db optimization runs
            "repair_interval" => 0, // time (in minutes) between db repair runs
        ),

If your dbtype is pgsql like the example above, you will have to wait for the next XI release for the fix.
