[Pkg-cacti-maint] Bug#860271: cacti: polling at a higher frequency than cron doesn't work due to php 7 deprecation of split()

[Paul Gevers]

Package: cacti
Version: 0.8.8h+ds1-8
Severity: serious
Justification: breaks usability in valid and supported use case
Tags: pending patch

poller.php calls split() in two places, which is deprecated in PHP 7.
The code in question isn't run by default, but it causes problems when
the administrator configures cacti to poll data at a higher frequency
than the cron job that runs the poller. As the highest cron frequency is
once per minute, one will have to use this feature if higher resolution
is required.
