Hrm, probably I know how that possible:
- your apache still use old php (5.x), check it in About page (https://<observium>/about/). While poller/discovery used new php (7.x).
Check your packages and remove old ones:
dpkg -l | grep apache2-mod-php | grep ii

I checked php.ini files, they are default from debian9. No mention of this function being blocked.
Confirming that mt_rand() fix works fine.
root@nm:/opt/observium# svn revert includes/defaults.inc.php
Reverted 'includes/defaults.inc.php'
root@nm:/opt/observium# svn up
Updating '.':
U includes/defaults.inc.php
Updated to revision 10952.
Use random_int() function in this place completely not neccesary, I replace it with mt_rand().
But this is completelly impossible that this is function not exist on any php7.x.
This is native function, not loaded as module!
Only way - if function blocked by php.ini config.
Yep, just some additional information after looking at this a bit more - this is a Debian 9 machine, which doesn't natively have php 7.1 or 7.2 in repo.
The install guide still seems to suggest that Debian 9 is supported, but I see the software requirements have been updated to list 7.1 as min.
So, I'd suggest you either need to say Debian 9 no longer supported (because lack of php 7.1/7.2 natively) or include library for backwards compatibility.
Mike might work around this by loading the library (i guess it's only loading for 5.6, and almost no one used 7.0, so it's not been noticed), but you should definitely upgrade this install anyways.
Yeah, 7.0 was a dumb release, missing a bunch of things that you'd otherwise associate with 7.x. it was never really one that we supported, we skipped straight to 7.1, which is the current minimum.

It's possible we're no longer loading the back support parts of the library, landy would know.
indeed, that was the issue. somehow apache had reverted to using 5.x through some debian update. once forced back to 7, svn head works fine.
Thanks!!
