Best app for graphing services?

[Alex]

Hi,
I've been using munin to graph performance of services like mariadb and
apache, but looking for something different or better. I thought cacti
might be that program, but it's not really designed to graph at the
individual application level.

Is there something different you're all using these days that might be
worth considering?

munin is okay, but I never felt like it was very accurate, in addition to
requiring lots of regular maintenance to make sure the scripts are working
properly.

Thanks,
Alex
