Cache DB RRsets graph is changed.
Cache DB RRsets is a number records in DNS cache database, I mistakenly thought that is number requests to DNS cache database.
I can’t find any description named.stats file for Bind 9.6 and high. Has anyone seen such description?

Help

Hello dima_dm!

the values in my graph are not the same of the zabbix_named.stats.txt

why?

[dima_dm]

See configuration of items. Store value can be As is, Delta (speed per second), Delta(simple change). In the last 2 case, you can see this effect.

Thanks

1) Check path to named stat file
my $stats='/var/named/chroot/var/named/data/named.stats'
2) Check, that size оf one statistics sample < $data in Byte.
my $data=10000
