Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the

||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|

||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.
|
||||
|
||||

# Go gRPC Interceptors for Prometheus monitoring

|
||||
|
||||
[Prometheus](https://prometheus.io/) monitoring for your [gRPC Go](https://github.com/grpc/grpc-go) servers and clients.
|
||||
|
||||
A sister implementation for [gRPC Java](https://github.com/grpc/grpc-java) (same metrics, same semantics) is in [grpc-ecosystem/java-grpc-prometheus](https://github.com/grpc-ecosystem/java-grpc-prometheus).
|
||||
|
||||
## Interceptors
|
||||
|
||||
[gRPC Go](https://github.com/grpc/grpc-go) recently acquired support for Interceptors, i.e. middleware that is executed
|
||||
by a gRPC Server before the request is passed onto the user's application logic. It is a perfect way to implement
|
||||
common patterns: auth, logging and... monitoring.
|
||||
|
||||
To use Interceptors in chains, please see [`go-grpc-middleware`](https://github.com/mwitkow/go-grpc-middleware).
|
||||
|
||||
## Usage
|
||||
|
||||
There are two types of interceptors: client-side and server-side. This package provides monitoring Interceptors for both.
|
||||
|
||||
### Server-side
|
||||
|
||||
```go
|
||||
import "github.com/grpc-ecosystem/go-grpc-prometheus"
|
||||
...
|
||||
// Initialize your gRPC server's interceptor.
|
||||
myServer := grpc.NewServer(
|
||||
grpc.StreamInterceptor(grpc_prometheus.StreamServerInterceptor),
|
||||
grpc.UnaryInterceptor(grpc_prometheus.UnaryServerInterceptor),
|
||||
)
|
||||
// Register your gRPC service implementations.
|
||||
myservice.RegisterMyServiceServer(s.server, &myServiceImpl{})
|
||||
// After all your registrations, make sure all of the Prometheus metrics are initialized.
|
||||
grpc_prometheus.Register(myServer)
|
||||
// Register Prometheus metrics handler.
|
||||
http.Handle("/metrics", promhttp.Handler())
|
||||
...
|
||||
```
|
||||
|
||||
### Client-side
|
||||
|
||||
```go
|
||||
import "github.com/grpc-ecosystem/go-grpc-prometheus"
|
||||
...
|
||||
clientConn, err = grpc.Dial(
|
||||
address,
|
||||
grpc.WithUnaryInterceptor(grpc_prometheus.UnaryClientInterceptor),
|
||||
grpc.WithStreamInterceptor(grpc_prometheus.StreamClientInterceptor)
|
||||
)
|
||||
client = pb_testproto.NewTestServiceClient(clientConn)
|
||||
resp, err := client.PingEmpty(s.ctx, &myservice.Request{Msg: "hello"})
|
||||
...
|
||||
```
|
||||
|
||||
# Metrics
|
||||
|
||||
## Labels
|
||||
|
||||
All server-side metrics start with `grpc_server` as Prometheus subsystem name. All client-side metrics start with `grpc_client`. Both of them have mirror-concepts. Similarly all methods
|
||||
contain the same rich labels:
|
||||
|
||||
* `grpc_service` - the [gRPC service](http://www.grpc.io/docs/#defining-a-service) name, which is the combination of protobuf `package` and
|
||||
the `grpc_service` section name. E.g. for `package = mwitkow.testproto` and
|
||||
`service TestService` the label will be `grpc_service="mwitkow.testproto.TestService"`
|
||||
* `grpc_method` - the name of the method called on the gRPC service. E.g.
|
||||
`grpc_method="Ping"`
|
||||
* `grpc_type` - the gRPC [type of request](http://www.grpc.io/docs/guides/concepts.html#rpc-life-cycle).
|
||||
Differentiating between the two is important especially for latency measurements.
|
||||
|
||||
- `unary` is single request, single response RPC
|
||||
- `client_stream` is a multi-request, single response RPC
|
||||
- `server_stream` is a single request, multi-response RPC
|
||||
- `bidi_stream` is a multi-request, multi-response RPC
|
||||
|
||||
|
||||
Additionally for completed RPCs, the following labels are used:
|
||||
|
||||
* `grpc_code` - the human-readable [gRPC status code](https://github.com/grpc/grpc-go/blob/master/codes/codes.go).
|
||||
The list of all statuses is to long, but here are some common ones:
|
||||
|
||||
- `OK` - means the RPC was successful
|
||||
- `IllegalArgument` - RPC contained bad values
|
||||
- `Internal` - server-side error not disclosed to the clients
|
||||
|
||||
## Counters
|
||||
|
||||
The counters and their up to date documentation is in [server_reporter.go](server_reporter.go) and [client_reporter.go](client_reporter.go)
|
||||
the respective Prometheus handler (usually `/metrics`).
|
||||
|
||||
For the purpose of this documentation we will only discuss `grpc_server` metrics. The `grpc_client` ones contain mirror concepts.
|
||||
|
||||
For simplicity, let's assume we're tracking a single server-side RPC call of [`mwitkow.testproto.TestService`](examples/testproto/test.proto),
|
||||
calling the method `PingList`. The call succeeds and returns 20 messages in the stream.
|
||||
|
||||
First, immediately after the server receives the call it will increment the
|
||||
`grpc_server_started_total` and start the handling time clock (if histograms are enabled).
|
||||
|
||||
```jsoniq
|
||||
grpc_server_started_total{grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream"} 1
|
||||
```
|
||||
|
||||
Then the user logic gets invoked. It receives one message from the client containing the request
|
||||
(it's a `server_stream`):
|
||||
|
||||
```jsoniq
|
||||
grpc_server_msg_received_total{grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream"} 1
|
||||
```
|
||||
|
||||
The user logic may return an error, or send multiple messages back to the client. In this case, on
|
||||
each of the 20 messages sent back, a counter will be incremented:
|
||||
|
||||
```jsoniq
|
||||
grpc_server_msg_sent_total{grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream"} 20
|
||||
```
|
||||
|
||||
After the call completes, its status (`OK` or other [gRPC status code](https://github.com/grpc/grpc-go/blob/master/codes/codes.go))
|
||||
and the relevant call labels increment the `grpc_server_handled_total` counter.
|
||||
|
||||
```jsoniq
|
||||
grpc_server_handled_total{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream"} 1
|
||||
```
|
||||
|
||||
## Histograms
|
||||
|
||||
[Prometheus histograms](https://prometheus.io/docs/concepts/metric_types/#histogram) are a great way
|
||||
to measure latency distributions of your RPCs. However, since it is bad practice to have metrics
|
||||
of [high cardinality](https://prometheus.io/docs/practices/instrumentation/#do-not-overuse-labels)
|
||||
the latency monitoring metrics are disabled by default. To enable them please call the following
|
||||
in your server initialization code:
|
||||
|
||||
```jsoniq
|
||||
grpc_prometheus.EnableHandlingTimeHistogram()
|
||||
```
|
||||
|
||||
After the call completes, its handling time will be recorded in a [Prometheus histogram](https://prometheus.io/docs/concepts/metric_types/#histogram)
|
||||
variable `grpc_server_handling_seconds`. The histogram variable contains three sub-metrics:
|
||||
|
||||
* `grpc_server_handling_seconds_count` - the count of all completed RPCs by status and method
|
||||
* `grpc_server_handling_seconds_sum` - cumulative time of RPCs by status and method, useful for
|
||||
calculating average handling times
|
||||
* `grpc_server_handling_seconds_bucket` - contains the counts of RPCs by status and method in respective
|
||||
handling-time buckets. These buckets can be used by Prometheus to estimate SLAs (see [here](https://prometheus.io/docs/practices/histograms/))
|
||||
|
||||
The counter values will look as follows:
|
||||
|
||||
```jsoniq
|
||||
grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="0.005"} 1
|
||||
grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="0.01"} 1
|
||||
grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="0.025"} 1
|
||||
grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="0.05"} 1
|
||||
grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="0.1"} 1
|
||||
grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="0.25"} 1
|
||||
grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="0.5"} 1
|
||||
grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="1"} 1
|
||||
grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="2.5"} 1
|
||||
grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="5"} 1
|
||||
grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="10"} 1
|
||||
grpc_server_handling_seconds_bucket{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream",le="+Inf"} 1
|
||||
grpc_server_handling_seconds_sum{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream"} 0.0003866430000000001
|
||||
grpc_server_handling_seconds_count{grpc_code="OK",grpc_method="PingList",grpc_service="mwitkow.testproto.TestService",grpc_type="server_stream"} 1
|
||||
```
|
||||
|
||||
|
||||
## Useful query examples
|
||||
|
||||
Prometheus philosophy is to provide raw metrics to the monitoring system, and
|
||||
let the aggregations be handled there. The verbosity of above metrics make it possible to have that
|
||||
flexibility. Here's a couple of useful monitoring queries:
|
||||
|
||||
|
||||
### request inbound rate
|
||||
```jsoniq
|
||||
sum(rate(grpc_server_started_total{job="foo"}[1m])) by (grpc_service)
|
||||
```
|
||||
For `job="foo"` (common label to differentiate between Prometheus monitoring targets), calculate the
|
||||
rate of requests per second (1 minute window) for each gRPC `grpc_service` that the job has. Please note
|
||||
how the `grpc_method` is being omitted here: all methods of a given gRPC service will be summed together.
|
||||
|
||||
### unary request error rate
|
||||
```jsoniq
|
||||
sum(rate(grpc_server_handled_total{job="foo",grpc_type="unary",grpc_code!="OK"}[1m])) by (grpc_service)
|
||||
```
|
||||
For `job="foo"`, calculate the per-`grpc_service` rate of `unary` (1:1) RPCs that failed, i.e. the
|
||||
ones that didn't finish with `OK` code.
|
||||
|
||||
### unary request error percentage
|
||||
```jsoniq
|
||||
sum(rate(grpc_server_handled_total{job="foo",grpc_type="unary",grpc_code!="OK"}[1m])) by (grpc_service)
|
||||
/
|
||||
sum(rate(grpc_server_started_total{job="foo",grpc_type="unary"}[1m])) by (grpc_service)
|
||||
* 100.0
|
||||
```
|
||||
For `job="foo"`, calculate the percentage of failed requests by service. It's easy to notice that
|
||||
this is a combination of the two above examples. This is an example of a query you would like to
|
||||
[alert on](https://prometheus.io/docs/alerting/rules/) in your system for SLA violations, e.g.
|
||||
"no more than 1% requests should fail".
|
||||
|
||||
### average response stream size
|
||||
```jsoniq
|
||||
sum(rate(grpc_server_msg_sent_total{job="foo",grpc_type="server_stream"}[10m])) by (grpc_service)
|
||||
/
|
||||
sum(rate(grpc_server_started_total{job="foo",grpc_type="server_stream"}[10m])) by (grpc_service)
|
||||
```
|
||||
For `job="foo"` what is the `grpc_service`-wide `10m` average of messages returned for all `
|
||||
server_stream` RPCs. This allows you to track the stream sizes returned by your system, e.g. allows
|
||||
you to track when clients started to send "wide" queries that ret
|
||||
Note the divisor is the number of started RPCs, in order to account for in-flight requests.
|
||||
|
||||
### 99%-tile latency of unary requests
|
||||
```jsoniq
|
||||
histogram_quantile(0.99,
|
||||
sum(rate(grpc_server_handling_seconds_bucket{job="foo",grpc_type="unary"}[5m])) by (grpc_service,le)
|
||||
)
|
||||
```
|
||||
For `job="foo"`, returns an 99%-tile [quantile estimation](https://prometheus.io/docs/practices/histograms/#quantiles)
|
||||
of the handling time of RPCs per service. Please note the `5m` rate, this means that the quantile
|
||||
estimation will take samples in a rolling `5m` window. When combined with other quantiles
|
||||
(e.g. 50%, 90%), this query gives you tremendous insight into the responsiveness of your system
|
||||
(e.g. impact of caching).
|
||||
|
||||
### percentage of slow unary queries (>250ms)
|
||||
```jsoniq
|
||||
100.0 - (
|
||||
sum(rate(grpc_server_handling_seconds_bucket{job="foo",grpc_type="unary",le="0.25"}[5m])) by (grpc_service)
|
||||
/
|
||||
sum(rate(grpc_server_handling_seconds_count{job="foo",grpc_type="unary"}[5m])) by (grpc_service)
|
||||
) * 100.0
|
||||
```
|
||||
For `job="foo"` calculate the by-`grpc_service` fraction of slow requests that took longer than `0.25`
|
||||
seconds. This query is relatively complex, since the Prometheus aggregations use `le` (less or equal)
|
||||
buckets, meaning that counting "fast" requests fractions is easier. However, simple maths helps.
|
||||
This is an example of a query you would like to alert on in your system for SLA violations,
|
||||
e.g. "less than 1% of requests are slower than 250ms".
|
||||

||||
