Network Switch Router Wizard not importing all interfaces

I'm using Nagios XI 5.6.6 on a Centos 7 64-bit VM.

I am trying to import a Zhone MXKF-1419 Chassis into monitoring. This is a GPON chassis that has roughly (5) 16 port line cards, (1) mgmt card, and (1) Fabric/Uplink card. The GPON chassis is built to allow 32 customer per port and maintains a large database of individual logical connections between the chassis and the customer regardless of customer presence. A single customer will have 5-6 logical connections for a single internet connection to their premise.

I am trying to monitor only the bare bones of each chassis which is roughly 50 OLT (physical) ports on the cards, and some standard device metrics (CPU/Temperature/Uptime etc). Nagios reads my gpon ports at 2.4GB even though they are 2.4GB down, and 1.2GB up. I run the import wizard, it sees all the 15000+ interfaces and then I go through and select all my physical ports to monitor and also tune the alarming so that my 50/80% thresholds are reflective of 50/80% utilization on the upload. When i go to submit the the wizard, it looks as if everything will work, but then when I look at my service states, it only shows the first card/group of ports.

The issue doesn't appear to be related to guts behind the Nagios platform as I can import ALL interfaces using the wizard if i don't try to manually deselect/tune any interfaces on the wizard. It seems almost like the wizard is timing out and missing all the data I'm trying to import for cards 2, 3, 4 etc.

I am NOT a server guy, I'm a network engineer that's learning Nagios. Please be gentle! :)

On a default system this can happen if you have not adjusted the max_input_vars php setting.

If this is a CentOS/RHEL system run the following

Code: Select all

echo "max_input_vars = 100000" >> /etc/php.ini
then restart httpd

Code: Select all

systemctl restart httpd
If it is not a CentOS/RHEL system let us know what OS/version and we can give you the commands.

Once this modification is made, if you re-run the wizard the rest of the interfaces should show up.
