Also instead of repeating the same bucket definitions everywhere just use a single top level var in the metrics package in order to discourage copy/pasting.
Fixes#3607.
There were two bugs in #3167:
All process-level stats got prefixed with "boulder", which broke dashboards.
All request_time stats got dropped, because measured_http was using the prometheus DefaultRegisterer.
To fix, this PR plumbs through a scope object to measured_http, and uses an empty prefix when calling NewProcessCollector().
In #2752, I accidentally introduced a change that would use a NewRegistry for
each NewPromScope, ignoring the Registry that was passed as an argument. Because
this registry was not attached to any HTTP server, the results would not get
exported. This fixes that, so the Registry passed into NewPromScope is
respected.
In the process, I noticed that stats were getting prefixed by a spurious "_". I
fixed that by turning prefix into a slice of strings, and combining them with "_"
only if it the slice is non-empty.
Fixes#2824.
Following up on #2752, we don't need to use global vars for our Prometheus stats. We already have a custom registry plumbed through using Scope objects. In this PR, expose the MustRegister method of that registry through the Scope interface, and move existing global vars to be fields of objects. This should improve testability somewhat.
Note that this has a bit of an unfortunate side effect: two instances of the same stats-using class (e.g. VA) can't use the same Scope object, because their MustRegister calls will conflict. In practice this is fine since we never instantiate duplicates of the the classes that use stats, but it's something we should keep an eye on.
Updates #2733
This removes the config and code to output to statsd.
- Change `cmd.StatsAndLogging` to output a `Scope`, not a `Statter`.
- Remove the prefixing of component name (e.g. "VA") in front of stats; this was stripped by `autoProm` but now no longer needs to be.
- Delete vendored statsd client.
- Delete `MockStatter` (generated by gomock) and `mocks.Statter` (hand generated) in favor of mocking `metrics.Scope`, which is the interface we now use everywhere.
- Remove a few unused methods on `metrics.Scope`, and update its generated mock.
- Refactor `autoProm` and add `autoRegisterer`, which can be included in a `metrics.Scope`, avoiding global state. `autoProm` now registers everything with the `prometheus.Registerer` it is given.
- Change va_test.go's `setup()` to not return a stats object; instead the individual tests that care about stats override `va.stats` directly.
Fixes#2639, #2733.
Uses a special mux for the OCSP Responder so that we stop collapsing double slashes in GET requests which cause a small number of requests to be considered malformed.
Rename HTTPMonitor to MeasuredHandler.
Remove inflight stat (we didn't use it).
Add timing stat by method, endpoint, and status code.
The timing stat subsumes the "rate" stat, so remove that.
WFE now wraps in MeasuredHandler, instead of relying on its cmd/main.go.
Remove FBAdapter stats.
MeasuredHandler tracks stats by method, status code, and endpoint.
In VA, add a Prometheus histogram for validation timing.
The `promAdjust` function in `auto.go` previously allowed characters
that were not valid in prometheus metric names (e.g. '>'). This commit
updates `promAdjust` to remove invalid characters. The `TestPromAdjust`
function is updated with testcases that include invalid characters.
We have a number of stats already expressed using the statsd interface. During
the switchover period to direct Prometheus collection, we'd like to make those
stats available both ways. This change automatically exports any stats exported
using the statsd interface via Prometheus as well.
This is a little tricky because Prometheus expects all stats to by registered
exactly once. Prometheus does offer a mechanism to gracefully recover from
registering a stat more than once by handling a certain error, but it is not
safe for concurrent access. So I added a concurrency-safe wrapper that creates
Prometheus stats on demand and memoizes them.
In the process, made a few small required side changes:
- Clean "/" from method names in the gRPC interceptors. They are allowed in
statsd but not in Prometheus.
- Replace "127.0.0.1" with "boulder" as the name of our testing CT log.
Prometheus stats can't start with a number.
- Remove ":" from the CT-log stat names emitted by Publisher. Prometheus stats
can't include it.
- Remove a stray "RA" in front of some rate limit stats, since it was
duplicative (we were emitting "RA.RA..." before).
Note that this means two stat groups in particular are duplicated:
- Gostats* is duplicated with the default process-level stats exported by the
Prometheus library.
- gRPCClient* are duplicated by the stats generated by the go-grpc-prometheus
package.
When writing dashboards and alerts in the Prometheus world, we should be careful
to avoid these two categories, as they will disappear eventually. As a general
rule, if a stat is available with an all-lowercase name, choose that one, as it
is probably the Prometheus-native version.
In the long run we will want to create most stats using the native Prometheus
stat interface, since it allows us to use add labels to metrics, which is very
useful. For instance, currently our DNS stats distinguish types of queries by
appending the type to the stat name. This would be more natural as a label in
Prometheus.
Fixes#1576.
Adds a new package mock_metrics, with code generated by gomock, in order to test the change.
Modifies publisher.New to take a metrics.Scope and an SA, and unexport SA.
Moves core of submission loop into a separate function, singleLogSubmit, which can return an error rather than using the continue keyword. This reduces repetition of AuditErr lines, and makes it easier to put error statting in one place.
Adds a server side unary RPC interceptor which includes basic stats. We could also use this to add a server request ID to the context.Context to identify the call through the system, but really I'd rather do that on the client side before the RPC is sent which requires the client interceptor implementation upstream. Also updates google.golang.org/grpc.
