### Description I have successfully running my weaviate and also writing data already. Now i am trying to use Prometheus to get the monitoring stuff. However when i directly port-forward 2112, i can see all metrics having classname are equals to na for example: ```auto batch_durations_ms_count{class_name="n/a",operation="total_persistence_level",shard_name="n/a"} 10499 batch_durations_ms_bucket{class_name="n/a",operation="total_preprocessing",shard_name="n/a",le="10"} 7971 batch_durations_ms_bucket{class_name="n/a",operation="total_preprocessing",shard_name="n/a",le="50"} 8915 batch_durations_ms_bucket{class_name="n/a",operation="total_preprocessing",shard_name="n/a",le="100"} 10079 batch_durations_ms_bucket{class_name="n/a",operation="total_preprocessing",shard_name="n/a",le="500"} 10498 batch_durations_ms_bucket{class_name="n/a",operation="total_preprocessing",shard_name="n/a",le="1000"} 10499 batch_durations_ms_bucket{class_name="n/a",operation="total_preprocessing",shard_name="n/a",le="5000"} 10499 batch_durations_ms_bucket{class_name="n/a",operation="total_preprocessing",shard_name="n/a",le="+Inf"} 10499 batch_durations_ms_sum{class_name="n/a",operation="total_preprocessing",shard_name="n/a"} 214940.27587399905 batch_durations_ms_count{class_name="n/a",operation="total_preprocessing",shard_name="n/a"} 10499 batch_durations_ms_bucket{class_name="n/a",operation="total_uc_level",shard_name="n/a",le="10"} 217 batch_durations_ms_bucket{class_name="n/a",operation="total_uc_level",shard_name="n/a",le="50"} 5912 batch_durations_ms_bucket{class_name="n/a",operation="total_uc_level",shard_name="n/a",le="100"} 6874 batch_durations_ms_bucket{class_name="n/a",operation="total_uc_level",shard_name="n/a",le="500"} 8507 batch_durations_ms_bucket{class_name="n/a",operation="total_uc_level",shard_name="n/a",le="1000"} 9151 batch_durations_ms_bucket{class_name="n/a",operation="total_uc_level",shard_name="n/a",le="5000"} 10496 ``` ### Server Setup Information - Weaviate Server Version: 1.25.0 - Deployment Method: k8s - Multi Node?

Hi @Alan_Sun !! Have you deployed using our helm charts? I was not able to reproduce this on a single deployment in docker. I will need to follow up on this to try replicating the same environment. Can you see any outstanding logs? Thanks! ---

Hi @DudaNogueira , Yes I am using your official helm chart as following: ```auto |NAME |NAMESPACE |REVISION|UPDATED |STATUS |CHART |APP VERSION| |---|---|---|---|---|---|---| |ssdl-weaviate |ssdl-weaviate|34 |2024-06-03 14:25:44.220168 +0800 CST|deployed|weaviate-17.0.0 |1.25.0| ``` Of course we created our collections and inserted data into this collections by using following python code ```auto !pip install "weaviate-client==4.*" !pip install -U weaviate-client ``` init get client then ```auto import weaviate.classes.config as wvcc client.collections.create( name="EmilyTest1", properties=[ wvcc.Property( name="solution_number", data_type=wvcc.DataType.NUMBER ) ], replication_config=Configure.replication( factor=3 ), ) ``` Then batch import ```auto start_time = datetime.datetime.now() with client.batch.fixed_size(batch_size=200) as batch: with open("embedding_3m.pkl", "rb") as f: loaded_data = pickle.load(f) # objects = ijson.items(f, "item") for obj_soln, obj_vector in loaded_data.items(): properties = { "solution_number": obj_soln, } batch.add_object( collection="EmilyTest1", properties=properties, vector=obj_vector ) # Calculate and display progress counter += 1 if counter % interval == 0: print(f"Imported {counter} solutions...") end_time = datetime.datetime.now() delta_time = end_time - start_time print("Time taken:", delta_time) print(f"Finished importing {counter} solutions.") ``` ---

Hi! I believe this is only the case for the totals. In my environment I get: ```auto batch_durations_ms_count{class_name="Test_Batch",operation="object_storage",shard_name="2uApOMYRXmM7"} 247 .... batch_durations_ms_bucket{class_name="n/a",operation="total_persistence_level",shard_name="n/a",le="10"} 0 ..... ``` So all that entries that has class\_name as “n/a” is referring to the overall. those were my two configurations for the exposed metrics: # Expose metrics on port 2112 for Prometheus to scrape PROMETHEUS\_MONITORING\_ENABLED: true PROMETHEUS\_MONITORING\_GROUP: false Let me know if this helps. Thanks! ---

Hi, Yes, i have enabled prometheus monitoring thats why i am able to see the metrics through 2112. But i am still not seeing class\_name even for ms\_count. Are you also testing with batch upload with weaviate-client 4.\* ? ```auto batch_durations_ms_bucket{class_name="n/a",operation="total_preprocessing",shard_name="n/a",le="+Inf"} 10509 batch_durations_ms_sum{class_name="n/a",operation="total_preprocessing",shard_name="n/a"} 47322.00007900016 batch_durations_ms_count{class_name="n/a",operation="total_preprocessing",shard_name="n/a"} 10509 ``` ---

Can you check your values.yaml for those variables: ```auto PROMETHEUS_MONITORING_ENABLED: true PROMETHEUS_MONITORING_GROUP: false ``` if `PROMETHEUS_MONITORING_GROUP` is set to true, it will not expose per collection metrics. Let me know if this helps. Thanks! ---

Oh thanks for your tips. Looks good now. ---

Are you planning to change grouping in a way that it would expose class data? It makes sense to group shards if multi-tenancy is enabled, but it would still be good to see per class metrics ---

hi @SStalciuss !! Welcome to our community 🤗 What metrics are you looking for? We had recently a PR that touches this: > > > \### What's being changed: > This metric is a guage metric that represents the num…ber of collections per "node". Useful to have high level view of collections for operators. Also to sanity check after any migrations. > > Example: > \`\`\` > \# HELP weaviate\_schema\_collections Number of collections per node > \# TYPE weaviate\_schema\_collections gauge > weaviate\_schema\_collections{nodeID="weaviate-0"} 1 > \`\`\` > \### Review checklist > > \- \[\] Documentation has been updated, if necessary. Link to changed documentation: > \- \[\] Chaos pipeline run or not necessary. Link to pipeline: > \- \[\] All new code is covered by tests where it is reasonable. > \- \[\] Performance tests have been run or not necessary. There are probably some more metrics that could be interesting to expose. I suggest opening a new thread so we can discuss this further 🙂 Thanks! ---
