Interpretation of metrics in the InfluxDB and GrafanaUI

Deal all,

could anyone please provide some information on how to interpret the metrics in the grafana and influxdb. I see the following metrics: cpu, dick, dickio, kernel, mem, net, but when I run the load test with tm-bench configuration file: https://github.com/informalsystems/testnets/blob/master/tm-bench/README.md I do not see any differences in the metrics values. How can we get the information like failed transactions, average block time, block heght, etc. I have provided to following input to the tm-bench:
```
terraform apply \
-var influxdb_url=http://ec2-54-210-210-87.compute-1.amazonaws.com:8086 \
-var influxdb_password=oifwejficeofw438574398jc498r34n98cr \
-var keypair_name=srdjokey2 \
-var tendermint_node_endpoints=ec2-184-73-23-60.compute-1.amazonaws.com:26657,ec2-100-24-70-128.compute-1.amazonaws.com:26657 \
-var tmbench_time=360 \
-var tmbench_rate=1000000000
```

Many thanks for your time!
