Accelerate the PrometheusExporter data retrieval time - IBM/ibm-spectrum-scale-bridge-for-grafana GitHub Wiki
By default, the PrometheusExporter exposes the original values from the platform alongside the timestamps at which they were measured. However, this can slow down a ZIMON query due to the amount of data that needs to be transferred and formatted.
You can reduce the execution time by setting rawCounters to False in the config.ini file.
Note that in this case, the exposed timestamps will represent the time at which the value was added to a delta counter bucket.
Example:
Query result by rawCounters set to False. Timestamp set to first time point of a bucket period.

Another limitation is that sensors including 'increasing counters' metric types will still run in rawCounters mode. This is because a bucket returns a delta value for an increasing counter, which Prometheus will misinterpret.
Grafana-bridge automatically manages which sensors need to be exposed as rawCounters and which can be switched to bucket delta mode.
If any troubleshooting is required, you can verify the metric types using the HTTP REST API endpoint /metadata/sensormetrics.
If you are running grafana-bridge in a container, you can disable raw counters by using the environment variable "RAWCOUNTERS=False" when deploying the pod.
