Nagios Support Forum

Evening all. I've been asked to post the questions I have regarding the nagiosxi demo on here. I hope this is the correct place.

Im running the trial of nagiosxi and have a few questions about it but
am not sure who to ask.
1, When I point it at a cisco switch it brings back info on the ports
but names them port 1, port 2, port 1002 etc. How can I find out which port is
which. When I use MRTG it gives me the port description?

2, How often are the port stats run. With MRTG its every 5 mins. Im
wanting to do it every 1 min on some kit and it would be good if this can do it.

3, im running version 2009R1.1H as when I tried 2009R1.2C I could not
get the performance graphs to work even after doing all the things
mentioned on this forum.

4, How can I load my config from nagios core to see how it all works on XI?

Many thanks

Lee

#1. I'm going to have to defer this one to another support team members as I haven't worked with that particular plugin much.

#2. You can change the "check interval" for a service by logging into the Core Config Manager -> Services ->Modify icon->Check Settings. I believe the default it 5 minutes, which is pulled from a service template. You can override this setting by changing it for the desired service.

#3. You might try upgrading to 2009R1.2D, as version C had a known bug with both switches and windows monitoring. Otherwise, our best known solutions are listed on our FAQ wiki. http://support.nagios.com/wiki/index.ph ... _Displayed

#4. We have a couple of Docs that explain migrating from Nagios Core in our Administrator's manual. http://assets.nagios.com/downloads/nagi ... ngfromcore

Hope that helps!

Thanks for the info.
On point 2 I asked because i was not sure what nagiosxi uses for graphing as mrtg carnt do any less than 5 mins even if you config it for 1 min. will test it

When I click check for upgrade it just fails but I will look into this as may be a firewall issue. But as I said I tried the lastest version but found the performance graphs did not work even after going through the FAQ

I will go though the admin manual for the migration

Thanks

MRTG is used and status information is pulled from it's database. I'm not familure with the UI either, but it's likely that this would be simple to implement... You can download and re-upload a patched wizard.

Monitoring once a min is supported and the default increment of 60 seconds can be changed... though this has never been tested and the results are unknown.

Thanks for the help. I have now got it running 1.3 and all seems good. My problem is I imported all the hosts from our nagios core install and these are all running as expected watching them using ping and snmp for uptime. I now want to get it to monitor ports which is where im having issues. From my original post who is it that can help with the port name side of things when using the network switch monitoring wizard? Also I have all the devices now in nagiosxi but only want to add the port monitor but am unsure how.
Once I have this I will look at what you suggested about changing the poll times.

One other. Would is be possible to use smoke ping in nagiosxi?

Thanks

Lee

Please provide us with the output of cfgmaker from mtrg, find other recent topic describes how. I'm not familiar with exactly how this wizard works, but I am aware that it needs some improvement in this area.

It's possible to download the Wizard, patch it up and then re-upload it.

Thanks for the link. Im guessing that all I have to do is a normal install of smokeping then install this plugin. I will get the mrtg files on here next

Thanks

I've downloaded the network-switch wizard and had a look. I have noticed that its using the following for doing the cfgmaker:
$cmd=$cfgmaker_cmd." --noreversedns ".$snmpcommunity."@".$address." > ".$outfile." ; touch ".$donefile." > /dev/null &";

To me it looks like cfgmaker has been left to its defaults which is "--ifref=nr interface references by Interface Number (default)" My current MRTG setup that is not part of nagiosxi uses --ifref=descr ... by Interface Description which names each interface by name. I tried to modify the wizard but I dont know php so was only guessing and it did not work. I also have --no-down in my config so if you were to monitor a core switch/router it will watch all ports even if nothing is plugged in at that time. Saves you having to re run it when you do use the port.

If someone can let me know if this can be fixed/changed as i dont know php so would just be guessing.

Thanks

I've been testing the performance graphs update times to see if it can do 1 min checks. I pointed the switch wizard at a cisco switch that is not currently on nagiosxi. It found the ports etc and I changed the monitor host to every 1 minute. I left it for 30 mins and looked at the performance graphs. It looks like host performance ping and ping run every 1 min but the ports usage still only runs every 5 mins. Would be good to have the ports checked evey 1 min or so.


Thanks

Lee

Each service has it's own check time, typically set in a shared template.

I'll pass these suggestions to our config-wizard team.
