Configured, Enabled Nodes not showing up under Minemeld > Nodes.

[nbilal]

After reboot, none of the configured nodes (all enabled) are showing up under "Nodes". Tried restarting services and VM. Further configuration commits without any errors, but still no nodes show up.

Minemeld logs attached. (/opt/minemeld/logs/*)

Any ideas where to start troubleshooting?

Hi Nasir,

you should install additional packages:

librabbitmq1
libsnappy1
libleveldb1

You can see the error in minemeld-engine.log, the engine is trying to load a missing shared library:

There's about 4000+ occurrences of this error in the Engine logs:

"ImportError: libleveldb.so.1: cannot open shared object file: No such file or directory" where is that file supposed to be and how can I get it? Perhaps some library didn't install properly?

Should I just do an apt-get install libleveldb-dev?

Beat me to it by 3 minutes! 🙂

Had to reboot my workstation...will try in a few and let you know.

Thanks!

You don't need the -dev packages as all the code is already compiled inside the MineMeld packages. Just the "production" packages I have listed in the previous message.

That was it. I will add these to the posted solution under the Proxy discussion for future reference. Thanks!
