Since i think the last update the alerts send by telegram only contain variables and not the content anymore output see below. I did already an apt-get update and upgrade.
Validate php does not give any clue here. I do have an issue with te time in php, seems i need to find out where the php.ini is located for librenms since the setting is there in the php.ini of apache.
Willing to debug but need some guidance here.

message in telegram:
%title

Severity: %severity

{if %state == 0}Time elapsed: %elapsed

{/if}Timestamp: %timestamp

Unique-ID: %uid

Rule: {if %name}%name{else}%rule{/if}

{if %faults}Faults:

{foreach %faults} #%key: %value.string

{/foreach}{/if}Alert sent to: {foreach %contacts}%value <%key> {/foreach}

Further investigation.
When i want to make a test message from librenms it fails
Test to telegram failed general error.

Hi,

No, telegram transport is not broken.

Also, seems like you werent updating from long time ago.

Check Deprecation notice: Alerting - Legacy transports and templates and update your templates :wink:

strange the daily updates were processed. i wil look into the info thanks

Checked, removed all old transport and old rules, and create new ones under alerts to be sure.
Created a new bot based on this document : Transports - LibreNMS Docs
From there there is a small corrrection needed in the document. After creaton of the bot, you need to start the url to activate the bot otherwise the bot will anwer the url in de example with : {“ok”:true,“result”:[]}
After talking to the bot then you get the jason result back.
But , after the whole procedure … no luck
the message pop ups and then no further actions possible.

Iirc, you configure your bot to use html or markdown.

You must select the same in your transport settings.

conversion done seems test does work.

Darn test alerts do work, but the system does not transport, logging shows this message.
I do not receive alerts in telegram. While test alerts do work.
Any Clue?? Where could i debug this issue?

But i see only one transport, so seems we have found the issue … but how to solve it since the transport is recreated and when i do a test with telegram the message is popping up…

Rule name: Devices up/down
Alert rule: macros.device_down = 1
Alert query: SELECT * FROM devices WHERE (devices.device_id = ?) AND (devices.status = 0 && (devices.disabled = 0 && devices.ignore = 0)) = 1
Rule match: no match

Found 1 transports to send alerts to.
Transport: mail

Debug :

Here i have a problem, syntax error?

Do you mind posting your template?

Seems you have something wrong in it

13

{{ $alert->title }}
Severity: {{ $alert->severity }}
@if ($alert->state == 0) Time elapsed: {{ $alert->elapsed }}
@endif Timestamp: {{ $alert->timestamp }}
Unique-ID: {{ $alert->uid }}
Rule: @if ($alert->name) {{ $alert->name }} @else {{ $alert->rule }} @endif
@if ($alert->faults) Faults:
@foreach ($alert->faults as $key => $value) #{{ $key }}: {{ $value[‘string’] }}
@endforeach @endif Alert sent to: @foreach ($alert->contacts as $key => $value){{ $value }} <{{ $key }}> @endforeach

Ok.
In the last line remove the < > surrounding the $key var.

To look like this:

Done, if i want to test the transport how could i create a forced alert? should i play with the -s or is there another script needed to force the transport, the telegram standard test does work from the transport interface but that is the standard test message.

root@nms:/opt/librenms/scripts# ./test-template.php -t 0 -d -h 192.168.1.14 -r 4 -s 0
No alert found, make sure to select an active alert.

16

What I usually do to test templates is to create a “fake alert” that will trigger in normal conditions.

For example, port utilization, I just set it to a value that is already lower than the actual usage so it will trigger.

The correction works thanks
