Hi,
I have multiple logwarnings about a depricated PHP:
PHP Deprecation(8192): Invalid characters passed for attempted conversion, these have been ignored in /opt/librenms/includes/polling/ntp/cisco.inc.php:67
And the lines 70 and 74.
This is about the SNMP cntpPeersOffset value Hex-STRING, which is containing spaces:
00 00 00 00
The log warning is about hexdec(‘00 00’).
