Top Error / top-errors.blade.php not outputting information

I have seen where the Alerts widget did not work if I used URL http://IPaddress on my browser to access. If I used the domain name i.e. http://something.com the alerts widget worked fine. This was partially due to my Nginix config server_name and web UI global settings>Server> Specific URL set as specific http://something.com when it needed to be / or blank. Suspect the Top Error maybe due to a config error but I haven’t found it.

Check your browser’s developer console for errors. It will likely show if a bad url is being generated.

The browser developer console isn’t reporting any errors. However, from the server CLI mariadb shows aborted connections. Looking to see if `max_allowed_packet’ needs to be increased. My mariadb versioin is 15.1 Distrib 10.6.18-MariaDB. I haven’t found this setting in my /etc/mysql/ .cnf files but do see it in the mariadb glogbal variable output. Would the aborted connections cause Top Errors to not work?

There are a few errors but nothing I can see related to Top Erorrs.

This page uses the non standard property “zoom”. Consider using calc() in the relevant property values, or using “transform” along with “transform-origin: 0 0”. ferris.test.adtran.com

I am seeing this error in my nginix error log but validate shows no issues.

A Deprecated message won’t cause any issues (it is just an indication that it will break in a future PHP version)

Can you check if this is still an issue with 24.11.0?

8

I have found that the Alert Stats on each device no longer works. I suspect that is why the Top Errors widget isn’t working. I can upgrade to 24.11.0 but not sure how that will fix Libre.

9

You’re not sure how upgrading would fix the issue? Upgrading LibreNMS is how you receive bug fixes.

10

I upgraded and things seem to have broken. It was reporting several things but the most important is that I run pip install -r /opt/librenms/requirements.txt. With Ubuntu 24 this cannot be run until adding
librenms@ferris:~$ cat /etc/pip.conf
[global]
break-system-packages = true
After running pip install -r /opt/librenms/requirements.txt I see that the poller is not running and no python wrapper pollers found [FAIL]. Frustrating… Any pointers on how to fix this.

I performed a system reboot and the poller seems fine now. However, the alert stats and Top Error widget still not working. Do you see anything wrong with these settings?

Everything is upgraded. Still Device Alerts and Top Errors remail blank. What DB and DB entries should I look at for content availability for these screens or widgets? The HTML debug does show some interesting information. For some reason the dataset it is pulling is really old. See output below:

Thought you meant upgrading OS. Earlier I sent additional info regarding my findings after upgrading to 24.11

14

For PIP packages FYI, the current install docs install all required python packages via APT, so you don’t need to use PIP.

15

Are you sure your response regarding PIP is for this issue? As previously stated I have upgraded to Libre 24.11.0 and my Ubuntu version is 24.10. The DB Schema show [quote=“Ricky_Boydston, post:12, topic:26455”]
2024_11_07_110342_custommap_edge_add_text_align (307)
[/quote] Still appears that Top Errors and Device Alerts are not working. I did happen to catch a HTML error yesterday that isn’t showing up so far today. See my previous response for details [quote=“Ricky_Boydston, post:12, topic:26455”]
Debug on Device Alerts page shows
Uncaught TypeError: vis.Graph2d is not a constructor

Any steps for guidance to resolve would be greatly appreciated.

Thank you for your time and help!

Top Errors and Device alerts are not functioning after all atempts to fix. Other than the errors below I see nothing indicating what might be wrong. What areas should I look at regarding the Top Errors widget not working? Does Top Errors read data from RRD? If possible, please provide a list of some items that you would normally check and how.

Top Errors widget on the Default Dashboard debug shows
[Violation] ‘setTimeout’ handler took 58ms jquery.gridster.min.js?ver=05072021:1

Device Alerts page debug output continues to show Uncaught TypeError: vis.Graph2d is not a constructor
at alert-stats:4882:19

Thank you!
