Hi all, I'm going to adopt cacti[1]. But I have a problems with a clean upgrade path to the new upstream version.
Cacti use a mysql database to store the configuration values (including
users/password, graphic options, layouts, ...). The new upstream version
(0.8.x) use a completly new designed database structure then the old
version, which is currently already packed for Debian.
I have tried to write some postinst scripts to migrate the existing
database into the new one, but I think now this is impossible, because
maybe informations which are needed in the new version are missing in
the old one.
Some other packages like sysstat simply prints a message about a
incompatible dataformat, and move or delete the old datafile. Is this an
acceptable way for such a program also? And if so, should I do a
database export first, before deleting and recreating the database with
the new tables?
Any hints are welcome :-)
Thanks for your help
Thorsten
[1] Description: Frontend to rrdtool for monitoring systems and services
Cacti is a complete frondend to rrdtool, it stores all of the necessary
information to create graphs and populate them with data in a
MySQL database. The frontend is completely PHP driven. Along with being
able to maintain Graphs, Data Sources, and Round Robin Archives in
a database, cacti handles the data gathering also. There is also
SNMP support for those used to creating traffic graphs with MRTG.
