WeatherMap editor and php 8.1 : incompatibility?

Hello everybody,

As recommended by the VALIDATE of LIBRENMS, I updated my version of PHP to 8.1.
Since php 8.1 update (7.3 to 8.1), my weathermap editor doesn’t work. Have you also encountered this problem ?
I have errors like this in several php function :
“Unsupported operand types: string / int”

Has anyone found a solution ?

Best regards,
Olivier

There seems to be active talk and testing relating to this here which will hopefully find an answer soon: https://github.com/librenms-plugins/Weathermap/issues/78

At the end of that is a fork with changes that might fix it that they are requesting people to test before they submit a pull request: https://github.com/LoveSkylark/LibreNMS-Weathermap

I have the same issue after upgrading to php 8.1

php check.php

Fresh install of Ubuntu 22.04.1 LTS with PHP 8.1.2 and the latest merged updates from Multiple fixes by LoveSkylark · Pull Request #82 · librenms-plugins/Weathermap · GitHub - all works fine. Needed to install php-pear.

check.php isn’t needed for any of it, but change the curly brackets to square brackets on line 261 and it works.

Are you definitely using the correct repository including PR #82?

I still have issues after git pull on weathermap plugin too,

error seems to be different depending on what map you are rendering
e.g some you have loads of depreciation warnings, seem to complete, but then i get empty image. Other weathermaps which are more complex i get a php fatal error

PHP Fatal error:  Uncaught TypeError: count(): Argument #1 ($value) must be of type Countable|array, null given in /opt/librenms/librenms/html/plugins/Weathermap/lib/WeatherMapLink.class.php:162

There’s my validate.php. Am running Ubuntu 20.04 LTS all was fine up until the upgrade to php8.1. Any help on this would be greatly appreciated. Also first time poster so apologies if formatting is incorrect etc. and let me know if you need more information.

Also I’m running nginx with this install.

Hi,

I had the same problem and then I discovered that the error is associated with the type of data (BWLABEL ) presented in the links, if you selected BWLABEL bits; it does not present the editor, but if you go to the code and comment or remove it change the default (percentage) you will already have the editor back, after editing back to bit, I’ve been doing this since updating php.

/opt/librenms/html/plugins/Weathermap/configs/<mapname.config>

TEMPLATE-only LINKs:

LINK DEFAULT
WIDTH 5
BWFONT 1
COMMENTFONT 100
BWLABEL bits

Hi I am also having issue.

I pulled from master. Chown all files to librenms. Fixed directories executable bit. Added php to cron job for map-poller.php script.

Editor works ok. But maps are without link usage values. I guess the issue is in

ERROR: realpath(XXXX.oob.XXX.local/port-id1106.rrd): No such file or directory

Hate to admit this but it turns out my initial issue where none of the button working in the editor is a browser issue - it doesn’t work in Microsoft Edge (surprise surprise!)

I then had another issue where it wasn’t updating I had to modify the cron job for the map-poller.php execution to the following:

*/5 * * * * librenms php /opt/librenms/html/plugins/Weathermap/map-poller.php >> /dev/null 2>&1

Hopefully some of you other guys get your issues fixed!

HI,

I did the exact same.

But my maps have no data.

Do your maps show link utilization?

If I run the map-poller from CLI I see among other ERROR: realpath(172.16.56.1/port-id14480.rrd): No such file or directory.

Hey,

Yeah all my maps are showing utilization fine I just had the issue with them not uodating also I dont get that error when I run the map-poller.php manually.

Sorry I cant help further.

I’m also experiencing the same issue and have not been able to solve it yet.

So I was poking around some more this morning in relation to the maps not showing any link data. If I comment out the $rrdcached in the /opt/librenms/config.php after about 15 minutes my map will return to normal.

I suspect there is a path issue between the $rrdcached or possibly a permissions issue? but there is nothing related in the installation/configuration notes for Weathermap that pertains to rrdcached.
