In librenms.log i have some error like this:

[2018-08-22 09:14:02] production.ERROR: Symfony\Component\Debug\Exception\FatalThrowableError: Parse error: syntax error, unexpected '' (T_ENCAPSED_AND_WHITESPACE), expecting identifier (T_STRING) or variable (T_VARIABLE) or number (T_NUM_STRING) in /home/librenms/includes/alerts.inc.php(401) : eval()'d code:3
Stack trace:

#4 /home/librenms/includes/alerts.inc.php(797): IssueAlert(Array)

#6 {main}

It is a problem because some alert doesn’t send. When I test with scripts/test-alert.php and scripts/test-template.php I don’t have any problem. I convert all my template.

My validate.php is good:

root@mon3:/home/librenms# ./validate.php

Component Version
LibreNMS 1.42.01-63-ge448190a6
DB Schema 260
PHP 7.0.30-0+deb9u1
MySQL 10.1.26-MariaDB-0+deb9u1
RRDTool 1.6.0

====================================

[OK] Composer Version: 1.7.2
[OK] Dependencies up-to-date.
[OK] Database connection successful
[OK] Database schema correct

Somebody can help me ?

I would change the sensor value template as a test.

Try make it simple at first and take a backup of the template,

I think it might be related to this line @php echo ($value['sensor_current']-$value['sensor_limit']); @endphp
Delete that whole line and try change it to just {{ $value['sensor_current'] }} and
{{ $value['sensor_limit'] }}

There may be a small formatting error somewhere causing this error. If it continues, un-map your templates 1 by 1 to debug.
