Not detect VsZ

[jeremyit]

Hi, I've tried your plugin to check my ap status from my Virtual SmartZone, this is the return

RUCKUSVSZ UNKNOWN - Device is not a Ruckus SCG device - System description is SmartZone - No data available
unknown: Device is not a Ruckus SCG device - System description is SmartZone

Is not compatible ?

[cygnusb]

Which Version are you running? My guess is you are running a much newer version then we are and this has not been tested on current versions. (our version is 3.5) You can try and change:

if not str(self.snmpclient.sysdescr).startswith("SmartCell Gateway"):

to:

if not str(self.snmpclient.sysdescr).startswith("SmartZone"):

This should enable you to get over this sanity check. Please let me know if there are other issue afterwards. I hope the basic SNMP MIBs have not changed. So my guess is that it could work even with newer versions.

[jeremyit]

I am currently on 3.5 but soon on 5.1. Migration is planned. I've done replacement in code but same issue

./check_ruckus_vsz -H 192.168.X.X -C xx-vvv RUCKUSVSZ UNKNOWN - Device is not a Ruckus SCG device - System description is SmartZone - No data available unknown: Device is not a Ruckus SCG device - System description is SmartZone Probing Ruckus SCG device 192.168.x.X through SNMP Queried Ruckus SCG device 192.168.x.X through SNMP - device is reachable Found Sysname vsz01 and sysdescr SmartZone

[cygnusb]

Can you send me the first lines of a snmpwalk of the device (20 or so)? In addition you can simply remove the lines:

if not str(self.snmpclient.sysdescr).startswith("SmartCell Gateway"):
            raise nagiosplugin.CheckError("Device is not a Ruckus SCG device - System description is %s" % self.snmpclient.sysdescr)

and check again?

[jeremyit]

Same issue with 2 lines removed. snmpwalk.txt

[cygnusb]

Thanks. It seems that you have two versions on your system. The one installed and the one on the checkout. With the two lines removed the issue cannot happen, if you use the correct source.

Please make sure the two lines are remove and then reinstall using:

python setup.py install

This will make sure that the installed version has also the two lines removed

[cygnusb]

And one more question: Is your system a Smartzone 100 or 300? Like a phyiscally installed box or just a virtual machine?

[jeremyit]

ok, done. Now this is output RUCKUSVSZ UNKNOWN: MibNotFoundError: No module RUCKUS-SCG-SYSTEM-MIB loaded at <pysnmp.smi.builder.MibBuilder object at 0x7fcc68832050>caused by <type 'exceptions.ValueError'>: invalid literal for int() with base 10: 'RUCKUS-SCG-SYSTEM-MIB::ruckusSystemStatsWLANTotalRxPkts' It's only a VM so called VirtualSmartZone

[cygnusb]

Same as ours. Can you try calling it from the git checkout directly? ./check_ruckus_vsz .... and not from the installed version? The MibNotFoundError results from the script not able to find the mib. If you call it directly from the git checkout it should propably work

[cygnusb]

I think I found the issue. Need to add an option to the setup.py. Please stash your changes and pull from github. That should solve your issue on the installed version

[jeremyit]

done, now : RUCKUSVSZ UNKNOWN: RuntimeError: Cannot query oid %r if multiple varBinds keys are present

[cygnusb]

Strange. Same as #1 but you are running the same version we are running. Can you please pull again and execute with -vvv option. I added some more debug output to clarify why this happens

[jeremyit]

OK cygnusb. Thanks.

[cygnusb]

Ok. It seems that this fails on the first Ruckus specific MIB entry. So my guess is either there is a misconfiguration of SNMP communities?!? or your device is not providing all data. Can you please do a: snmpwalk -v2c -cCOMMUNITY HOSTNAME 1.3.6.1.4.1.25053

on the device and provide me with the details? You could add a

snmpwalk -v2c -cCOMMUNITY HOSTNAME 1.3.6.1.4.1.25053 | cut -d: -f1,2,3

this should cut out all sensitive data (please double check)

[cygnusb]

Found the snmp walk in centreon project. Will take a look

[cygnusb]

It seems your device is at least missing the total tx/rx statistics, which are present in oid 1.3.6.1.4.1.25053.1.3.1.1.1.15.5.0

I added some checks to ignore this and also make the code not fail completely in this case. Might not really be perfect. Please pull and let me know.

[jeremyit]

yeah! thanks! strange thing all values connected configured are 0

[cygnusb]

No its not really working. It seems now all data is missing except the basic system data. I reverted the change and handled this again.

Please check if that works and please provide full -vvvv output

[jeremyit]

out.log

[jeremyit]

Just tried vscg-5.1.2.0.302, but same issue. Basic system data reported, but impossible to control aps status

[cygnusb]

Can you please make snmpwalk on the ruckus controller. You need to copy all *.txt files from ruckus_vsz_snmp/ directory to ~/.snmp/mibs/ dir. And add mibs +ALL to ~./snmp/snmp.conf

When this is setup, you will be able to run: snmpwalk -v2c -cYOUR_COMMUNITY YOUR_RUCKUS_IP RUCKUS-SCG-WLAN-MIB::ruckusSCGAPMac

In addition you can try this with the corresponding mibs for 5.1.2.

I might not be able to properly fix this issue, since we do not plan to move to a newer version at the moment and have no way to test this.

[cygnusb]

Can you please retry this with the latest version? Should hopefully be resolved

[cygnusb]

Remaining issues should be fixed in #3

[jeremyit]

sorry for delay and thank you for the job. It's working with my 5.1.2 !

[cygnusb]

Great! Glad to hear it is also working with an newer ruckus release. Thanks for the feedback.
