Apache Pinot

Hi Team,
We are trying to understand the Pinot metrics exposed to Prometheus. While looking into the segments error metrics *"pinot_controller_segmentsInErrorState_Value"*, it states that "Number of segments in error state". However, we see that we do have some of the segments in bad state but the same is not reflected in Prometheus Graph. The count shows 0

If you are referring to `BAD` status in the console, check the external view to ensure that is the case. I think someone else reported an issue where console reports `BAD` for consuming segments. I had requested for opening a GH issue, so there might already be one

Thanks <@UDQU92KBK> for the reply. I will verify the status in the external view

<@UDQU92KBK> ,
Yesterday we had some of the segments for our table in BAD state, this was visible from the UI. We have a chart in Grafana monitoring the counter ("*pinot_controller_segmentsInErrorState_Value").* The expectation was that this graph would show us the count of segments that are in BAD state. However, the graph showed nothing. Also, we noticed that the graph is showing a line with a very low negative value.
Attaching the screenshot for the reference
We would like to know following points here:
1. What exactly the negative value represent in the chart?
2. Is ERROR state and BAD state different when it comes to segment?
