Alf-Rune Siqveland 95bbd81f7d feat: Add configuration option to enable/disable profiling metrics 
Added a new configuration `enable_profiling_metrics` which
enable/disable the default runtime metrics exported by the Prometheus
client package.

BREAKING CHANGE: Changed default behavior to exclude runtime metrics.
        Enable with enable_profiling_metrics configuration option.

Christian Schneider cd459836a6 Improved error reporting. 2024-03-25 10:15:05 +01:00
Christian Schneider 9f92116fe3 Support multiple configs per input metric. 
When generating metric values using expression evaluation, there are new
use-cases for more than one configuration for each sensor value.
Expressions are more flexible than aggregation rules in Prometheus, so
it makes sense to derive multiple metrics from the same sensor input.
 2024-03-25 10:15:05 +01:00
Christian Schneider f380bea81d Support metrics from arithmetic expressions. 
This change adds the new metric config option `expression` which can
define a complex expression to calculate the final metric value. The
expression is evaluated using github.com/antonmedv/expr as the engine,
see expr-lang.org/docs/v1.9/Language-Definition for a language overview.
In addition, some basic functions are available during evaluation: now,
int, float, round, ceil, floor, abs, min, max.

For each evaluation, the expression gets:
- the current MQTT value
- the last MQTT value
- the result of the last evaluation
- the elapsed time since the last evaluation

Expressions allow more flexibility to derive metrics from sensor inputs
which are very hard or even impossible to do in Prometheus, for example,
integrate continuous values over time, filter extreme or zero values, or
non-linear scaling. The last value, result, and timestamp are preserved
even between restarts of mqtt2prometheus. This means that expressions
can be used to produce continuous time series over a long time range.

To make upstream integration easier, the code depends on the rather old
v1.8.9 of github.com/antonmedv/expr, which is available in the main repo
of all supported Debian versions.

Christian SchneiderandChristian Schneider 4943c97963 Add option to enforce strict monotonicy in metrics. 
This change adds the new option `force_monotonicy` to metric
configurations. It is intended for almost-but-not-really monotinic
sources, such as counters which reset when the sensor is restarted.

When this option is set to `true`, the source metric value is regularly
written to disk. This allows us to detect and compensate counter resets
even between restarts. When a reset is detected, the last value before
the reset becomes the new offset, which is added to the metric value
going forth.  The result is a strictly monotonic time series, like an
ever increasing counter.
