Is it something wrong with my graph setting, plugin or anything.
Your help are much appreciated.

You are looking at 7 day graph which will consolidate and average data points. On a 24 hour graph the peak may have been higher

Correct me if i'm wrong, only for 24 hour graph will have the actual value of check/notification because of the way RRD database do the averaging.

If that's the case, is there any way or workaround so that we can always have the actual value always being populated on the graph?
We have situation where the incident manager highly dependent on nagios xi graph to review the report (normally received 2/3 days after the incident resolved).

Thanks.

the only way to change the graphing would be to modify the rra.cfg, delete all existing graphs and recreate them

Modifying the rra.cfg is described below, but, be sure you read the whole article as changes will significantly increase the size of the rrd files and disk space used on the system
