Hi everyone, I figured out what was going on. The method that create a
gauge metric takes a numeric value as a function. I imagine that this
function is somehow executed in a lazy way, and that was the problem. The
"function" that I was passing was actually a simple number, and the value
was never updated.
For anyone having this issue, here is a snippet from the code that I wrote:
private final Map<String, AtomicInteger> statusCodes = new HashMap<>();
.
.
.
private void createOrUpdateMetric(String healthType, Status status) {
statusCodes.put(healthType, new AtomicInteger(healthToCode(status)));
Gauge.builder(HEALTH, statusCodes, statusCodes ->
statusCodes.get(healthType).get())
.tags(Tags.of(Tag.of(HEALTH_TYPE, healthType)))
.description(HEALTH_DESCRIPTION + healthType)
.register(meterRegistry);
}
