I upgraded my LibreNMS instance to PHP 8.1 relatively recently and have not been able to access the Weathermap editor since. I am getting the following error after enabling debugging.

{
"message": "Attempt to assign property "configline" on null",
"exception": "Error",
"file": "/opt/librenms/html/plugins/Weathermap/lib/Weathermap.class.php",
"line": 1840,

"line": 848,
"function": "ReadConfig",
"class": "WeatherMap",
"type": "->"
}
]
}

I have tried the recommended actions in the LibreNMS Community but did not have any success with resolving the error.

Hello,

I'm making a migration of a LibreNMS server to a new server with a new URL.
I found that full URL are used on the maps generated with the plugin editor (eg librenms.example.com/...) for fields infourl and overlibgraph.

I suggest to use relative URL (as it's work ;-)) to avoid the need to edit the conf files when changing the URL.

I have been installing fresh instances for clients with the latest weathermap on this repo and a fresh install of librenms. I follow the instructions https://github.com/librenms-plugins/Weathermap/blob/master/INSTALL.md

everything seems great until I started adding a node and Pick from LibreNMS.

Here is the log dump from my error logs. Librenms owns the files and i am not sure whats going on.

Hi All,
I was trying to integrate weathermap with librenms. The integration works but when I try to create the map from the librenms admin page, I don't see the following files created
map_name.jpg and map_name.html

1. Checked under Weathermap-NO
2. Check under weathermap/output-NO
   However, the map_name.conf gets created under Weathermap/configs directory. Please advice.

Hi,

Have you plan to upgrade to the last Weathermap version (0.98) ?

Regards,
Stéphane

Good morning.
I installed weathermap plugin into librenms. Then I activated this plugin, and I can created map.
But I can't see anywhere my created weathermaps? Should I do edit or turn on something?
Or maybe copying / install missing dependencies?

Where should be link to weathermap in libreNMS menu?
Thank you in advance for your response.

Best regards,
Janusz Janik

I am getting this error regardless if i chmod 777 configs or chown apache:apache configs.

Thanks in advance.

On platforms that are not case-sensitive (Windows, Mac OS X), cloning this repository causes significant grief. The filesystem (and therefore git) will view Weathermap.php and weathermap.php as the same file, and when cloning, you will get only one of those files. Then you'll see some nonsense about having untracked files, and it's an all-around mess. Here's an example:

 ❯ git status                                                                                                                                                                                                                                                                                                                                                    [14:33:30]

The only work-around, for OS X at least, is to create a new partition that is case-sensitive. For Windows, I'm not sure of a potential workaround (if any exists). On Linux, this obviously isn't a problem.

Would it be possible to rename the files such that there is more that is different about them than just the case?

I've done a fresh install of LibreNMS, and cloned from github. Even setting the permissions for the entire WeatherMap directory to 777 did not output any html pages.

Am I mssing something. I can get to the editor, and my .conf file are saving. Am I missing something? how would I then see the Weathermap?

I am trying to print optical RX value on whether map in Librenms but it does not match from an actual value I am using
SET rrd_use_poller_output 1 but not fix the issue

Printed Value on weather map

Actual value is
-2.23 dBm but the printed value is 1.6dBm

So I have a web front-end that polls, a second regular cronjob poller, and two servers that run the librenms-poller-service. The last server is a SQL server that runs memcached, rrdcached, and of course the SQL backend. The SQL server is also the NFS host of the RRD files for all 4 pollers.

When I run the map poller regularly, I get a lot of links with 0's reported for traffic in the links. When checked with rrdtool, it is in fact missing data for the 800 second time frame. When I run /opt/librenms/html/plugins/Weathermap/weathermap.php with the additional --chdir /my/rrd/path, I get a lot more values filled in, but many are missing. I tried adding the --daemon ip.of.my.server:42217 and it didnt seem to help, like it can't read anything in rrdcached.

If i change the config on rrdcached to WRITE_TIMEOUT=720 and WRITE_JITTER=360, I'm then able to get 90% of my links populated with traffic on the map. I saw that WeatherMapDataSource_rrd reads back the last 800 seconds of an rrd, so it seemed the only way to get data to come through was to neuter my rrdcached setup.

TL;DR - How do I get Weathermap to accurately read rrd values from rrdcached when Weathermap is on a different server from the rrdcached server?

For my installation of librenms (which was a pre-build vm-image) the map-poller.php needs the shebang #!/usr/bin/env php in order to be executed correctly by cron.

Here's a bunch of changes I did to get rid of various warnings.

Not everything is fixed: strftime will need something better. And the $num_points is also a thing...

I also needed fix to #88.

Hi

I would like to display ping latency in my maps as shown below. Can someone assist I pointing out I could do this.

Thanks

After updating to PHP 8.1 & Weathermap 697ac3c, Weathermap seems to still be incompatible.

From the logs:

hello to all a few days ago I updated the php version from 7.4 to 8.1 and when I install the Weathermaps plugin this error is skipped,

Someone can help me ?

Hello

I have an issue when RRDCached is enabled.
If enabled there is no data on graphs or graphs are partially filled.

Here is why.
By default path in TARGET is something like this (configs/*.conf):

TARGET ./10.0.0.1/port-id42.rrd:INOCTETS:OUTOCTETS

When rrdtool fetch command is executed, RRDCached returns this:

flush ./10.0.0.1/port-id42.rrd
Nothing to flush: /opt/librenms/rrd/./10.0.0.1/port-id42.rrd.

This means that data from cache is not written to disk.
So data is outside time window, no recent values.

When I removed ./ from all TARGET then Weathermap works as expected (data shown):

flush 110.0.0.1/port-id42.rrd
0 Successfully flushed /opt/librenms/rrd/10.0.0.1/port-id42.rrd.

I think you should change this line.
Add exception if RRDCached is enabled.

My RRDCached configuration is from docs page.

I'm a subscriber of the Observium platform, and am looking at moving over to LibreNMS. One thing I like is that the Weathermap plugin for Observium has an entry in the navbar along the top. I've installed the weathermap plugin in my LibreNMS instance, but was wondering if there was something similar to allow quick access to my maps.

Hi!
I want to make custom link to file map-poller.php (to refresh map every time I want, not even from cron).
So, i added this link, but during execution, I get error

#!/usr/bin/env php ERROR: map-poller.php should ONLY be run as a CGI script!

I'm using nginx with php-fpm. How can i execute this file from interface?

Hello!
I don't know if anyone is actively maintaining this plugin, but I have (what I believe is) a small feature request.

It would be cool having the labels changing color depending on the node being up or down on in LibreNMS, similar to how it looks in Mikrotik The Dude.

I believe it is the LABELBGCOLOR option mentioned in the Weathermap's documentation (https://network-weathermap.com/manual/0.97b/pages/config-reference.html#NODE_COLORS) which needs to be intergrated with the LibreNMS macros.device_up/down macro.

When setting a data source for a port, if the device hostname/ip is an IPv6, the html file will show the graph but not the values on the links (they show 0 and down).

This way of doing sources with IP's instead of hostnames work in IPv4.

rrdcached requires relative paths from the perspective of $config['rrd_dir']. Weathermap attempts to use relative paths from the perspective of /opt/librenms/html/plugins/Weathermap.

poller-map.php fails to create maps don't have --base-href and also lib/datasources/WeatherMapDataSource_rrd.php cant read rrds.

I noticed today that when logged in as a non-admin user in librenms, the edit config HREF is available on the weathermap landing page. It appears to be fully functional and I can load the map editor as an unprivileged user.

Hi,

I´ve setup weathermap and so far the maps are created. But how can I display the maps inside librenms-gui? Right now I have to access the maps like: https:///plugins/Weathermap/map.html?
Also the hover images doesn´t display. Thank you for your support.

Hello,

It is the same issue than #76 but it was closed without solution given by the user.
I'm using CentOS Stream 8 with php8.1.5 from remi repo, nginx 1.14.1, MariaDB 10.3.28, Laravel 8.80.0, RRDTool 1.7.0, and LibreNMS 22.4.0-18-g70bae6605 with 2022_04_08_085504_isis_adjacencies_table_add_index (236) database schema.
If I install weathermap with LibreNMS documentation, LibreNMS fall in error state with error 500 and ksort(): Argument #1 ($array) must be of type array, null given log.
At the moment I delete Weathermap folder, LibreNMS is working again.
@cabello123 says to solved the issue by "adding missing arrays to the function".

Does someone know where does it come from?

I'm trying to use this to give a "max traffic of last 24 hours" map:

SET rrd_start now-1day
SET rrd_period 86400
SET rrd_aggregate_function MAXIMUM

At least with rrdtool 1.5.5 this is only showing traffic in one direction, the other is 0. This is because WeatherMapDataSource_rrd.php is skipping the first (supposedly blank) line. Removing the skip fixes it for me and doesn't seem to cause additional problems (it's checking for IN/OUT strings anyway and skipping other lines).

Hi there

We've noticed that the index.php (https://github.com/librenms-plugins/Weathermap/blob/master/index.php) references "../index.php". But looking at our plugins folder (and the one in upstream https://github.com/librenms/librenms/tree/master/html/plugins) There isn't any "index.php".

If we want to open a config (Overview -> Plugins -> Weathermap configname.conf) It then throws en error 404 trying to access said index.php.

What are we doing wrong?

libreNMS version: 1.64.1-26-g300645388

I checked all the installation process and I've even removed it and clone it again with the same result. My Apache directives the one recommended in Librenms install instructions and the install validate. I can't figure out what I'm missing.
Thank U for any help.

I have done a fresh install of LibreNMS 22.8.0 in Alma linux 8.6 and working fine. Then i am trying to include Weathermap with LibreNMS following docs (Weathermap - LibreNMS Docs).
I have created Weathermap but when I click on plugins > weathermaps > *.conf I get a 404 error from the index. I have also checked and found didn’t generated .html file in “/opt/librenms/html/plugins/Weathermap/output/”.

I have also checked by latest version ubuntu and also found same issue.

Is anyone else having this problem with the weathermap plugin?. Plese help me.

More problem details here https://community.librenms.org/t/html-pages-not-being-automated-created-in-output-folder-opt-librenms-html-plugins-weathermap-output/19480

When adding nodes and links, only the values of the links are visible, graphs are working, nodes are ok.
In the debug I see "skipping 4 of 4 points".

Hello,

We run the weather map plugin for librenms and it works great, except for one link always shows 0% despite having traffic on it.

We can use and monitor other links from this device just fine, and we've tried recreating the link in the weather map. I also tried a rediscover of the entire device in LibreNMS but that did not help either.

Any suggestions on where I could look?

Thank you!

I just installed librenms on 16.04 with nginx following the instructions on
http://docs.librenms.org/Installation/Installation-Ubuntu-1604-Nginx/.

After cloning this repo and following its instructions, I created a map and everything works until I try to mouse over the nodes or links. The url that it is trying to access which is the url also shown in the .conf file is missing a / between the host and the path. Example:

NODE 1
        LABEL localhost
        INFOURL http://librenms.home.localdevice/device=1/
        OVERLIBGRAPH http://librenms.home.localgraph.php?height=100&width=512&device=1&type=device_bits&legend=no
        POSITION 336 289

Should be

NODE 1
        LABEL localhost
        INFOURL http://librenms.home.local/device/device=1/
        OVERLIBGRAPH http://librenms.home.local/graph.php?height=100&width=512&device=1&type=device_bits&legend=no
        POSITION 336 289

Manually fixing it solves the issue. Haven't been able to figure out yet what is causing it. Never had this problem using it with cacti for a decade or so. Not sure if nginx is stripping too much using the given virtual server template maybe (http://docs.librenms.org/Installation/Installation-Ubuntu-1604-Nginx/)?

Everything else works great ;)

is there an updated planned to 0.98?

Hi there,

Is there any chance this will be updated to newer php-weathermap codebase, to support newer php versions?

Thank you.

I'm new to weathermap in Librenms so please be gentle. I have build a map and it is working pretty well, however, the links I created between network devices often show no traffic even though hovering over them shows significant traffic flow. I am assuming that I have a configure item that needs to be updated by I haven't been able to find it. Can anyone point me in the right direction?

Hello,

When clicking on "Pick from LibreNMS" in link properties, I get the properties window, but with an error. The following is logged:

hello ,

i want to know if is it possibleto update the weathermap from 0.97c to 0.98 in librenms

and i yes how please

The map link produced on the weathermap plugin page looks wrong:
output/backbone.png.html

Looks like the $overlib['basename'] is the wrong one to use on line 27 in Weathermap/Weathermap.inc.php

Since that produces output/backbone.png

This plugin should display the maps it generates on the plugin page (or provide navigation to reach the maps).

To allow weathermap use rrdcached only two lines at:
/html/plugins/Weathermap/lib/datasources/WeatherMapDataSource_rrd.php

But the interesting thing is that plugin detects
$config['rrdcached'] from config.php

WeatherMapper
Automatically generate weathermaps from a LibreNMS database using WeatherMapper Link

I have done this several times now to the letter - and nothing generates. So I added a few devices/links - and when I try to load the page:
http://usmlbnetmon.percepta.com/plugins/Weathermap/output/mymap.html

My regular dashboard pops up. I am betting my bottom dollar that I am missing something highly obvious - but thought I would throw this up here anyway.

PHP Fatal error: require(): Failed opening required '/opt/librenms/includes/init.php' (include_path='.:/usr/share/php:/usr/share/pear') in /opt/librenms/html/plugins/Weathermap/editor.php on line 50, referer: http://[librenmsIP]/plugin/p=Weathermap

fresh install, no "init.php" file anywhere on box... do i need to manually create this file or should it be included w/ the installation of Weathermap?

Discovered this fork after realizing the 'classic' php weathermap does not work with php 8.x and above. This appears to be forked as related to the LibreNMS project.

Is it possible to run this standalone WITHOUT LibreNMS? Ie like the traditional non plug in version.

This would imply that there is no 'picker' but only hand editing of config files, as is with the original version, which is fine.

When adding option "SET rrd_cf MAX" (or any other rrdtool CF), it is disregarded.

./lib/datasources/WeatherMapDataSource_rrd.php:

545                 $cfname = intval($map->get_hint('rrd_cf'));
546                 if($cfname=='') $cfname='AVERAGE';

Given that the value of rrd_cf will be a text string and not an integer, this check on line 545 is problematic.

Simply changing it to:
$cfname = $map->get_hint('rrd_cf');
resolves the problems.

Sorry, I can't fork / clone / edit / commit / push and submit a PR from here, but thought I should report this anyway given the simple nature of the fix.

Hi,
first issue submit here https://github.com/librenms/docker/issues/16

I’m trying to install weathermap on the official docker image crafted by @crazy-max.
I followed docs on a fresh install, it works.
But when trying in docker, the editor works but it can’t generate maps in output folder.

Thanks for all your work.
Sk4mi.

Weathermap seemed to not be reading RRDs properly when using rrdached on a socket such as unix:/run/rrdcached.sock

Stepping through the cmd as built in map-poller.php got me:

php ./weathermap.php --config /opt/librenms/html/plugins/Weathermap/configs/myconf.conf --base-href /plugins/Weathermap/ --daemon unix:/var/run/rrdcached.sock --chdir '' --debug

This threw:

DEBUG: [wmrrd_read_from_real_rrdtool@WeatherMapDataSource_rrd.php:245] /opt/librenms/html/plugins/Weathermap/configs/myconf.conf: RRD ReadData: Running: /usr/bin/rrdtool fetch myswitch/port-id5044.rrd AVERAGE --start now-800 --end now --daemon unix:/var/run/rrdcached.sock 
ERROR: realpath(myswitch/port-id5044.rrd): No such file or directory

So it's looking for the rrd file on an incomplete path. Running:

 /usr/bin/rrdtool fetch /opt/librenms/rrd/myswitch/port-id5044.rrd AVERAGE --start now-800 --end now --daemon unix:/var/run/rrdcached.sock 

Confirmed it worked, so for my issue to be fixed I had to modify map-poller.php line 71 to read:

if (!empty($config['rrdcached']))
{
    $cmd = $cmd." --daemon ".$config['rrdcached']." --chdir ".$config['rrd_dir'];
}

I then had to comment out two instances of the following in lib/datasources/WeatherMapDataSource_rrd.php:

// rrdcached Support: strip "./" from Data Source
if ($map->daemon)
{
    $rrdfile = trim($rrdfile,"^./"); 
}

Reading through previous pulls / commits I see that plenty of logic has been added recently by @LoveSkylark for their use case which I think uses rrdcached exposed via an ip:port as oppsed to a socket, so I would imagine some extra logic needs to be written around to account for when rrdcached references a socket......unless someone wnats to tell me I'm way off the mark!
