Update - Graphs

Help

Open dev console in browser and check for errors.

Also, click on the graph and turn on the rrdtool debug

22

Ok, how do I do this? Can you provide me some links from the documentation? Thanks so far.

23

For dev console, just press F12 in your browser and refresh page.

For the rrdtool debug, I meant show rrd command

This is what I get from the Chrome console:

DevTools failed to load SourceMap: Could not load content for chrome-extension://gighmmpiobklfepjocnamgkkbiglidom/include.preload.js.map: HTTP error: status code 404, net::ERR_UNKNOWN_URL_SCHEME

This is the RRD command:

That looks ok…

Are only the dashboard graphs broken or all of em?

26

All graphs are broken. This occured with a nightly build in March for the first time. I rolled back to 1.62 stable, that fixed it back then. Now with 1.63 stable out it re-occured…

27

Could it be some kind of user permission?

Do you remember when it happened to you so we can check what was merged that could affect your graphs

28

I didn’t mess with user rights in the filesystem. It started with the nightly build 28 days ago, when the graphs stopped working, identically to the threadopener.

29

I switched to daily 1.63.3 today but that didn’t fix the graphs.

Maybe it’ something about RRD 1.7.0? Unfortunately I can’t rollback to an older version.
At least, I’m happy I’m not the only one…

32

really need a fix for this asap :expressionless:

33

With permissions I mean if your user is admin in librenms gui

34

Yes, i just checked. Both, a user with admin rights and a read-only user, don’t get any graphs.

35

What if you run ./daily.sh, the output looks correct or have weird things?

Ok.

We are just with other user in our discord server trying to reach where the hell that \n is added.

It is added in the config.php file somehow, we are just now determining where.

What the user in discord is just doing now is:

Backup config.php (mv config.php config.php.bak)
Copy default config (cp config.php.default config.php)
Edit config.php to edit SQL credentials and relevant configuration (like rrdcached, base ref, etc)

If its a default install, only SQL credentials are needed.

cheers for doing some diagnostics with me on Discord

we have proved that a new config.php resolves the Graph issue, But need to find out now how we can fix existing config.php users have

39

The following worked for me
mv config.php config.php.bak - Move config
cp config.php.default config.php - copy default to new config

diff -u config.php config.php.bak - will show differences in current config and back up config

Then once i seen the difference i manually updated nano config.php

then ctrl + X and Y and save config.php

Then my graphs worked

heres an example of how my default config.php looked compared to config.php bak db password removed

Thanks, I will try this later and post my results.
