That's interesting. I've been disabling some of the data_processing_options in ndomod.cfg as listed in ndomod.h instead up until now. I should have probably done what you recommended and changed the event broker options as that's earlier in the process. I just tried like you said - the time saving looks the same but it does make more sense to do it your way as it's closer to where the data starts from. I have tinkered with some of the settings in ndo2db.cfg for how long to keep data for (I only ever really need the most recent data myself). So I now have: # Keep timed events for 24 hours max_timedevents_age=1440 # Keep system commands for 24 hours max_systemcommands_age=1440 # Keep service checks for 24 hours max_servicechecks_age=1440 # Keep host checks for 24 hours max_hostchecks_age=1440 # Keep event handlers for 24 hours max_eventhandlers_age=1440 This helped hugely on my old Nagios 2 server. I confess I didn't take comparative timings when I changed these on my Nagios 3 server. I just tried adding those indexes you recommended in another post, but it made little or no difference in my setup, probably because my tables are so small now anyway! I have no doubt that if I hadn't shrunk those tables the indexes would make quite a difference. What I'm wondering now is whether it would help if I moved the ndo2db process off my Nagios server and on to my database server (currently ndo2db lives on my Nagios server and connects to the database on the remote db server). Does anyone have any thoughts on that?
