BUG: mice and elephant not working

[eranra]

Initial investigation shows that we do not create the metrics

[mariomac]

Could it be that the Collector Ingest is not really forwarding the metrics as long as they come regularly?

The way I interpret this line: https://github.com/netobserv/flowlogs-pipeline/blob/main/pkg/pipeline/ingest/ingest_collector.go#L153 is that the "flush timer" is restarted each time a new metric arrive, so it won't forward them unless there is 1 complete second without receiving metrics.

(EDIT: this will be fixed in an upcoming PR)

The bug seems to be in these lines:

flowlogs-pipeline/pkg/pipeline/transform/transform_network.go

Lines 77 to 80 in e0d95f2

	expression, err := govaluate.NewEvaluableExpression(fmt.Sprintf("%s%s", outputEntries[rule.Input], rule.Parameters))
	if err != nil {
	continue
	}

The first %s corresponds to outputEntries[rule.Input] which is float64 (not a string). The error is

`Invalid token: '%!'`

But it's swallowed. @eran Is there a reason for not logging the error?

A simple solution would be to change it to %v. I'll submit a PR for that...
