Problems with graphs: red only, missing "Error drawing graph"

Tags: #<Tag:0x00007f0641f61b40>

I just set up librenms via the docker-compose.yml found on GitHub. Things are mostly working fine except for the fact that often times some of the graphs have some issues. However, refreshing the UI usually fixes that problem, though from time to time other graphs will come up incorrectly. An example:

Help would be greatly appreciated.

And another one:

Please run ./validate.php


Also check this FAQ.

I did do a validation before posting, I should’ve mentioned that. Anyway, here’s the output of ./validate.php:

bash-5.0# ./validate.php
Component | Version
--------- | -------
LibreNMS  | 1.58
DB Schema | 2019_10_03_211702_serialize_config (147)

RRDTool   | 1.7.2
SNMP      | NET-SNMP 5.8

[OK]    Installed from the official Docker image; no Composer required
[OK]    Database connection successful
[OK]    Database schema correct
[WARN]  IPv6 is disabled on your server, you will not be able to add IPv6 devices.
[WARN]  Updates are managed through the official Docker image

Is there any particular item in the FAQ that you are referring to? Because I am not seeing blank pages, nor is this related to snmpd since the graphs show correctly after refresh. Or was that just intended as a general hint?

Anyone having an idea?

did you try to rediscover the host?

I have this with every host. And it’s not that the data is missing. Once I refresh the browser, the graph shows up correctly. In that case, some other graph might go missing, that was showing before…
