Juniper GitHub's FlexViews not working on XMC 8.5.0.169

Alessandro_Maio — Thu, 17 Sep 2020 20:17:23 GMT

Dear collegues,

I have imported the right MIBs and I can see them working with the Extreme MIBs browser and the Java FlexView builder. I have tested SNMP communication between XMC server and the Juniper devices.

However the FlexViews give me only a blank screen without displaying any error. Below there is an example.

Have you got any suggestions?

Thank you

Hi Alessandro.

I guess one of the following:

the MIBs are not in the correct directory
The Option to use myMIBs is not enabled
There is some mib missing
Restart of the nsserver service was not performed

I did the test with 8.5.0.169 last week and FlexViews were working properly with JunOS

Good luck.

What directory to put MIBs to?
Enable use of myMIBs To enable the use of third party MIBs, go to OneView->Administration->Options->SNMP, the option 'use MyMIBS directory on the server' should be checked. Change of this value does need the service restart with:

you may check the server.log to see if there are any errors compiling those mibs. The compilation happens during the start of the nsserver.

Thank you Zdenek for giving me a check-list to challenge my configuration step by step. There must be something I think correct but it’s not actually:

the MIBs are both in the new and in the old locations (in case some script points to the other location). Googling I have found in some GTAC Knowledge article the two different location

/usr/local/Extreme_Networks/NetSight/appdata/VendorProfiles/Stage/MyVendorProfile/MIBs/

and

/usr/local/Extreme_Networks/NetSight/appdata/System/mibs/MyMibs/

The option to use MIBs is enabled as the one to use third party folders
I took the whole MIBs package from the Juniper website according to the version of our firmware 15.1R7.9 https://www.juniper.net/documentation/software/junos/junos151/juniper-mibs-15.1R7.8.zip
We restarted even the whole server, after that the nsserver service wasn’t enougth and there are errors indeed, this may be the point but I don’t understant them. They refers to all the imported DeviceVies and FlexViews with the same error. Here it is an example:

2020-09-22 13:59:44,530 ERROR [stderr] [Fatal Error] DeviceViewJuniperVLANPorts.xml:53:69: Attribute name "data-pjax-transient" associated with an element type "meta" must be followed by the ' = ' character.

Please check the DeviceViewJuniperVLANPorts.xml is XML format and not HTML format. Check the same with DeviceViewJuniperVLANPorts.xml

Thank you so much Zdenek!!!

Now it’s all working both the DeviceView and the FlexView!!!

Somehow all the files I downloaded from GitHub in these categories where HTML instead of XML.

We can close this question, best regards!

Thank you again!
