graphs and Traffic last 30 minutes not showing

Post by jswope »

In an air-gapped classified environment. I am not seeing the "Traffic last 30 minutes" on the dashboard nor the "Bandwidth graph" for any of my sources. The sflow data is reaching the system as I can see the top talkers for all 8 of my sources. I have confirmed that the directories under /usr/local/nagiosna are correctly owned by nna:nnacmd and permissions are set correctly.

I believe it may be caused by all of the security settings we have to enforce that is blocking something that needs to operate. I have disabled SELinux.

On a possibly related note, while creating the sources, I had to create the directories for each source under /usr/local/nagiosna/var in order to start the sources. I even created a bandwidth.rrd file just to see if that was an issue.

This is all on a clean RHEL8.10 VM. Manual install. Latest release of NNA.

Hey @jswope

It does sound like a security/permissions issue from what you posted. I am curious what is causing the need to manually create the source files in /usr/local/nagiosna/var/ makes me think its a permissions issue. However you mentioned that you already checked the permissions to be correct. When you initially created this directories manually, was SELinux still on, and if so after disabling it did you still need to manually make these file changes when making a new source?

Initially SELinux was on and I had to create the directory structure. I disabled SELinux during the last 4 and I still had to create the directory structure.

I should of asked this prior but was SELinux enabled during the installation as well? If it was enabled on installations it can cause issues with packages installing and the permissions set. SELinux can create issues with the permissions and the issues you are running into sounds like a permissions issue.

Looking into the code it looks like rrdtool package might be having an issue since the tool should create the bandwidth.rrd file. If you are so inclined could you also look into the devtools while on a source page that isnt showing the bandwidth graph and see if the execute?begindate request is returning a proper response?
