I went and found a LAG on one our JunOS boxes that had this. The RRD max value was set to 10G
rrdinfo .../port-id6710.rrd | grep -E 'max|min' | grep OCT
ds[INOCTETS].minimal_heartbeat = 600
ds[INOCTETS].min = 0.0000000000e+00
ds[INOCTETS].max = 1.2500000000e+10
I hit it with
./scripts/tune_port.php -h (device) -p ae0
Now it is …
ds[INOCTETS].minimal_heartbeat = 600
ds[INOCTETS].min = 0.0000000000e+00
ds[INOCTETS].max = 2.5000000000e+09
We do not have the autotune setup … but I have noticed I also don’t have any data since despite this change - I will see how it looks in a few hours.
It would be interesting to see what your MAX figures are on the appropriate RRD file.
It would be interesting to know if you are polling on a different host via rrdcached which may have an issue … see Issue with RRD tuning over rrdcached
