cacti does nor read interface list

dragec · Post by **dragec** » Fri Sep 23, 2005 3:53 am

on win xp i have cacti, latest, php .... standard instalation that works. I've managed to define som routers and everything is ok. But when I want to add one router with lots of interfaces, during phase of defining host, when cacti reads interface list, I have an empty screen and cacti is working and working and working .... and after some time if I connect to cacti I can see that it readed number of interfaces but list is broken, I do no see interfaces names or addresses or state. Did anyone have such an issue?

Thanks

Probably has something to do with PHP timing out or running out of memory. Try increasing both in your php.ini.

How can I debug this part of proccess, I mean reading of interfaces. Verbose query also does not produce any output to screen.

Does the interface query work on any other machine just fine or is broken for everything?

It is working ok for routers on LAN, and for routers accros WAN link with not so many interfaces, but with several routers with lots of interfaces and 4M link between him and cacti I have problem. Same thing is when I tried cacti on my pc. So there is a possibility that wan link causes this but I'd like to debug it

I am having the same issue... By any chance, are you using a VPN as part of your WAN?

..I'm wondering if it's a MTU issue with my VPN based WAN..

Did your changes help any? If so, can you elaborate on EXACTLY what you changed in your PHP.INI file...

Thanks!

Please walk the ifInterfaces MIB on the device in question. It is not unheard of to have agents that do not report the ifInterfaces in SNMP correctly. I have seen it on HP/UX as well as a few wireless devices. Post the output of that walk.

In addition, post the results of the "Verbose Query" in Cacti.

When I try to do a Verbose Query, it never returns, and remains at a blank screen... I've let it sit for over 30 minutes.

The device is a Catalyst 6500 switch, which I know responds correctly, as we have one that is not across a WAN site, and it responds perfectly. FYI, both of the CAT's have a large number of interfaces (>200 ports).

If you have any suggestions, I'd be interested in hearing them, as this is the one item that is still causing others to want to move away from Cacti...

Thank You for your help, and Cacti is an awesome product!

Luis,

We have all but the 6503 in production on our network in both IOS and CatOS varieties and do not have the same issues. However, where are your devices located from a latency perspective (aka MS latency)? Our largest latency is 150-300 ms for devices in Europe. Please let me know.
