Question

hi I m having trouble understanding some of the Grafana metrics we have a single Nebula importer instance running a history load to our cluster v3 2 0 8 nodes the importer logs a steady rate of ~250k rows s ```2022 09 13 08 05 02 INFO statsmgr go 89 Tick Time 290 00s Finished 71750768 Failed 0 Read Failed 0 Latency AVG 1887us Batches Req AVG 2043us Rows AVG 247416 41 s 2022 09 13 08 05 07 INFO statsmgr go 89 Tick Time 295 00s Finished 72978112 Failed 0 Read Failed 0 Latency AVG 1887us Batches Req AVG 2043us Rows AVG 247383 40 s ``` at the same time a Grafana metric `nebula storaged num add vertices rate 60 instanceName=~ $hosts ` is reporting ~110k rows s could someone help interpret this metric pls thank you

Jingchun · Answer

just curious in importer the 250k s only insert vertices or actually there re edges as well

Marija Zelić · Answer

only vertices

Jingchun · Answer

what about the batch size in your importer config

Jingchun · Answer

num add vertices is the number of calls to this add vertices operator you may insert a batch upon one call so the rate might not be aligned with the amount of vertices added Try num vertices inserted instead

Marija Zelić · Answer

batchSize is 16 but we ll try playing with different metrics tnx
