Series() will fetch all the metadata for a series, even if it's going to be filtered later due to time ranges. For 1M series we save ~1.1s if you only needed some of the data, but take an extra ~.2s if you did want everything. benchmark old ns/op new ns/op delta BenchmarkHeadSeries/1of1000000-4 1443715987 131553480 -90.89% BenchmarkHeadSeries/10of1000000-4 1433394040 130730596 -90.88% BenchmarkHeadSeries/100of1000000-4 1437444672 131360813 -90.86% BenchmarkHeadSeries/1000of1000000-4 1438958659 132573137 -90.79% BenchmarkHeadSeries/10000of1000000-4 1438061766 145742377 -89.87% BenchmarkHeadSeries/100000of1000000-4 1455060948 281659416 -80.64% BenchmarkHeadSeries/1000000of1000000-4 1633524504 1803550153 +10.41% benchmark old allocs new allocs delta BenchmarkHeadSeries/1of1000000-4 4000055 28 -100.00% BenchmarkHeadSeries/10of1000000-4 4000073 87 -100.00% BenchmarkHeadSeries/100of1000000-4 4000253 630 -99.98% BenchmarkHeadSeries/1000of1000000-4 4002053 6036 -99.85% BenchmarkHeadSeries/10000of1000000-4 4020053 60054 -98.51% BenchmarkHeadSeries/100000of1000000-4 4200053 600074 -85.71% BenchmarkHeadSeries/1000000of1000000-4 6000053 6000094 +0.00% benchmark old bytes new bytes delta BenchmarkHeadSeries/1of1000000-4 229192184 2488 -100.00% BenchmarkHeadSeries/10of1000000-4 229193336 5568 -100.00% BenchmarkHeadSeries/100of1000000-4 229204856 35536 -99.98% BenchmarkHeadSeries/1000of1000000-4 229320056 345104 -99.85% BenchmarkHeadSeries/10000of1000000-4 230472056 3894673 -98.31% BenchmarkHeadSeries/100000of1000000-4 241992056 40511632 -83.26% BenchmarkHeadSeries/1000000of1000000-4 357192056 402380440 +12.65% Signed-off-by: Brian Brazil <brian.brazil@robustperception.io> |

Prometheus
Visit prometheus.io for the full documentation, examples and guides.
Prometheus, a Cloud Native Computing Foundation project, is a systems and service monitoring system. It collects metrics from configured targets at given intervals, evaluates rule expressions, displays the results, and can trigger alerts if some condition is observed to be true.
Prometheus's main distinguishing features as compared to other monitoring systems are:
- a multi-dimensional data model (timeseries defined by metric name and set of key/value dimensions)
- a flexible query language to leverage this dimensionality
- no dependency on distributed storage; single server nodes are autonomous
- timeseries collection happens via a pull model over HTTP
- pushing timeseries is supported via an intermediary gateway
- targets are discovered via service discovery or static configuration
- multiple modes of graphing and dashboarding support
- support for hierarchical and horizontal federation
Architecture overview
Install
There are various ways of installing Prometheus.
Precompiled binaries
Precompiled binaries for released versions are available in the download section on prometheus.io. Using the latest production release binary is the recommended way of installing Prometheus. See the Installing chapter in the documentation for all the details.
Debian packages are available.
Docker images
Docker images are available on Quay.io or Docker Hub.
You can launch a Prometheus container for trying it out with
$ docker run --name prometheus -d -p 127.0.0.1:9090:9090 prom/prometheus
Prometheus will now be reachable at http://localhost:9090/.
Building from source
To build Prometheus from the source code yourself you need to have a working Go environment with version 1.13 or greater installed. You will also need to have Node.js and Yarn installed in order to build the frontend assets.
You can directly use the go tool to download and install the prometheus
and promtool binaries into your GOPATH:
$ go get github.com/prometheus/prometheus/cmd/...
$ prometheus --config.file=your_config.yml
However, when using go get to build Prometheus, Prometheus will expect to be able to
read its web assets from local filesystem directories under web/ui/static and
web/ui/templates. In order for these assets to be found, you will have to run Prometheus
from the root of the cloned repository. Note also that these directories do not include the
new experimental React UI unless it has been built explicitly using make assets or make build.
An example of the above configuration file can be found here.
You can also clone the repository yourself and build using make build, which will compile in
the web assets so that Prometheus can be run from anywhere:
$ mkdir -p $GOPATH/src/github.com/prometheus
$ cd $GOPATH/src/github.com/prometheus
$ git clone https://github.com/prometheus/prometheus.git
$ cd prometheus
$ make build
$ ./prometheus --config.file=your_config.yml
The Makefile provides several targets:
- build: build the
prometheusandpromtoolbinaries (includes building and compiling in web assets) - test: run the tests
- test-short: run the short tests
- format: format the source code
- vet: check the source code for common errors
- docker: build a docker container for the current
HEAD
React UI Development
For more information on building, running, and developing on the new React-based UI, see the React app's README.md.
More information
- The source code is periodically indexed: Prometheus Core.
- You will find a CircleCI configuration in
.circleci/config.yml. - See the Community page for how to reach the Prometheus developers and users on various communication channels.
