*I'd like to track firmware versions for a large fleet of hardware devices and wondering if Prometheus is suitable for this task. The data comes from a json API, as shown in the example below, where the firmware version is "1.7.8". (I've redacted extra information to make a minimal working example.)*
*I set this up as a module in json-exporter with firmwareVersion as a label; the problem is it creates a new time series every time a firmware version is updated.* That's all fine: a small amount of metric churn on each firmware update is not a problem. Conventionally such a metric would have a static value of 1, which makes it easier to use in join queries, but using its value for upTime as well shouldn't be a problem. Here's some background documentation for this way of working: https://www.robustperception.io/how-to-have-labels-for-machine-roles https://www.robustperception.io/exposing-the-software-version-to-prometheus https://www.robustperception.io/left-joins-in-promql https://prometheus.io/docs/prometheus/latest/querying/operators/#many-to-one-and-one-to-many-vector-matches Metrics like node_uname_info and node_os_info work this way. *I'd like to visualize this in Grafana with a state timeline where the X axis is a stack of each device by name, the Y axis is time, and each bar shows the firmware version string.* That is a Grafana question rather than a Prometheus question, so is probably best asked on community.grafana.com. I can tell you that I did set this up on a system to display state changes of drives in MegaRAID arrays from prometheus labels, and it worked fine. It had horizontal bars, with time on the X axis and the drive name and drive ID+state on the Y axis. I'm afraid that since I no longer have access to that system, I can't give you its exact config. Googling turns up https://stackoverflow.com/questions/68887416/grafana-state-timeline-panel-with-values-states-supplied-by-label but that looks more complicated than I thought I had done.
