NetData/YAMon3 Installation Help

[SingingHobo]

Good morning.

I've recently acquired an Asus RT-AC86u to replace a failing/outdated D-Link router. I've successfully installed the most recent Asuswrt-Merlin build (382.1_2) and have been running strong for about 24hrs without issue.

Today; I've begun the process of attempting to get either (or both) NetData and YAMon3 installed.

I've followed the Entware-NG guide for installation and did not experience any issues. My pre-formatted EXT2 USB drive (2GB) is installed into the router.

From there, I installed NetData and I get the error message:

"Access to file is not permitted: /opt/share/netdata/web/"
​

Regarding YAMon3 - all indications are that it is running. Having installed it successfully on the D-Link router, I can run the installer to /opt/YAMon3 and there are no errors. /tmp/YAMon3.3-running exists in /tmp/ but accessing the site gives me a 404 error.

I've done some searching and haven't come across a solution to either of these issues.

In troubleshooting I've removed Entware-NG and re-installed. I've re-installed NetData and have the same results as prior (access error).

I'd love some guidance from anyone who has encountered similar.

Thanks.

From there, I installed NetData and I get the error message:
"Access to file is not permitted: /opt/share/netdata/web/"

Edit

netdata.conf

[web]
 web files owner = admin
 web files group = admin
 # default port = 19999
 # bind to = *

change to

[web]
 web files owner = admin
 web files group = root
 # default port = 19999
 # bind to = *

and restart netdata.

Also I recall you should disable 'python.d' and beware that there is a thread recommendation to reduce the logging for fear of wearing out NAND.

Thank you. That solved one problem. Just have YAMon to resolve now.

AC86u YAMon3 installed.

wow, i'd love to read about any success you have with this.
the one thing i miss most from my linksys wrt is yamon3.
i just assumed on asus+merlin it would not work at all.

update: so i got yamon3 working fine on my ac3100
