Claus Ibsen created CAMEL-26061:
-----------------------------------
Summary: camel-micrometer - the docs say a warning is logged where
the exchange fails
Key: CAMEL-26061
URL: https://issues.apache.org/jira/browse/CAMEL-26061
Project: Camel
Issue Type: Bug
Components: camel-micrometer
Affects Versions: 4.18.0, 4.22.0, 4.23.0
Reporter: Claus Ibsen
Fix For: 4.24.0
Found while adding the catalog body types of micrometer (CAMEL-24961), checked
with {{camel run}}. The body is fine; the docs say something else than the code
about failures.
h4. 1. A failure fails the exchange, but the docs say a warning is logged
The producer sets an exception on the exchange ({{AbstractMicrometerProducer}},
main 5aac7df76b83, line 77), but the docs say "Micrometer endpoint will catch
all exceptions and write log entry using level warn."
({{micrometer-component.adoc}}, line 152), and that a warning is logged for no
value (line 464) and for no or an invalid timer action (lines 612-615). Checked
on 4.24.0-SNAPSHOT with {{camel run}}: a summary value that is not a number
failed the exchange with a TypeConversionException to Double, and an invalid
CamelMetricsTimerAction one with a TypeConversionException to
MicrometerTimerAction; a missing value records nothing and logs nothing.
h4. Also read in the code, not run
* The CamelMetricsHistogramValue header is documented as a long
({{MicrometerConstants}}, line 30) and read as a Double
({{DistributionSummaryProducer}}, line 41).
* metricsType is required in the catalog, but a URI without it is a counter.
