Dear all,
I’m pleased to post here; this is my first post on the forum. I recently started using LibreNMS and am facing a difficulty. Specifically, I’m trying to set up a warning for the toner level of a Canon DX6855i so that when it reaches 5%, it sends me a Telegram notification to alert me.
I should mention that I already receive Telegram notifications for other things, so the system is already functional. However, I’m encountering difficulties with this printer and its related template. Before attempting to configure the printer, I read several forum posts, but they didn’t work for me.
I’m sharing the configuration used
and the error related to the template here:
#0 /opt/librenms/LibreNMS/Alert/RunAlerts.php(521): LibreNMS\Alert\Transport\Telegram->deliverAlert() #1 /opt/librenms/LibreNMS/Alert/RunAlerts.php(258): LibreNMS\Alert\RunAlerts->extTransports() #2 /opt/librenms/LibreNMS/Alert/RunAlerts.php(282): LibreNMS\Alert\RunAlerts->issueAlert() #3 /opt/librenms/alerts.php(54): LibreNMS\Alert\RunAlerts->runAcks() #4 {main} Transport delivery failed with 400 for ICT-Telegram: {"ok":false,"error_code":400,"description":"Bad Request: can't parse entities: Can't find end of the entity starting at byte offset 33"}

And here is the template:
**Title:** {{ $alert->title }}
👉 **Device Name:** {{ $alert->hostname }}
💥 **Severity:** {{ $alert->severity }}
**Timestamp:** {{ $alert->timestamp }}
@if ($alert->name)
⚙️ **Rule:** {{ $alert->name }}
@else
⚙️ **Rule:** {{ $alert->rule }}
@endif
🚨 **Toner Alert Level at 5%**
Do you have any suggestions?
Thanks in advance!!!
