Historical Data.
Posted: Tue Jun 29, 2010 2:38 pm
There are two sets of historical data. Graphs that are stored in RRD files and the Nagios Availability data. Both have certain constraints and would be migrated differently. Documentation on who what where and how would be splendid as well as some pointers on migrating these datasets.
Nagios Availability data:
On NagiosXI these records are "still" kept in flat files at /usr/local/nagios/var/archives and on your other Nagios installations the might be kept somewhere like this /var/log/nagios3/archives/. Simply copy non-conflicting files over. For conflicting files each line is time stamped at the vary start, take the last line in your historical data and prune any previous time from your target system. For time stamps that match that last time you may want to pick and choose what are conflicting and what should be done with each entry.
NagiosXI uses an ndodb system to keep track of all services and hosts, there may be an extra import procedure to push this data into the MySQL database.
