Sorry to tell contributors and users. We decided to archive the project temporarily due to the employee work plan of collaborators.

There are no more official support. Collaborators may offer a bit personal support.

Curve is an open-source tool to help label anomalies on time-series data. The labeled data (also known as the ground truth) is necessary for evaluating time-series anomaly detection methods. Otherwise, one can not easily choose a detection method, or say method A is better than method B. The labeled data can also be used as the training set if one wants to develop supervised learning methods for detection.

Curve is designed to support plugin, so one can equip Curve with customized and powerful functions to help label effectively. For example, a plugin to identify anomalies which are similar to the one you labeled, so you don't have to search them through all the data.

Curve is originally developed by Baidu and Tsinghua NetMan Lab.

Getting Started

Run and stop

Simply use to start or stop Curve.

./ start
./ stop

Server will blind 8080 by default, you can change it in ./api/uwsgi.ini.

The first start will take a while because of the compilation. If you pull updates from github, Rebuild will be triggered during start or reload.

Data format

You can load a CSV file into Curve. The CSV should have the following format

  • First column is the timestamp
  • Second column is the value
  • Third column (optional) is the label. 0 for normal and 1 for abnormal.

The header of CSV is optional, like timestamp,value,label.

Some examples of valid CSV

  • With a header and the label column
timestamp value label
1476460800 2566.35 0
1476460860 2704.65 0
1476460920 2700.05 0
  • Without the header
1476460800 2566.35 0
1476460860 2704.65 0
1476460920 2700.05 0
  • Without the header and the label column
1476460800 2566.35
1476460860 2704.65
1476460920 2700.05
  • Timestamp in human-readable format
20161015000000 2566.35
20161015000100 2704.65
20161015000200 2700.05


Recommend environments

For PC

Darwin(Mac OSX) or Linux(Ubuntu, CentOS, Arch, etc.) is Recommended

  • Dependency:
    • Python 2.7.3+/3.1.2+(Python 3 does not seem to be supported as of now.), if python is not owned by current user, virtualenv is required
    • Node.js 4.7.0+
    • gcc, pip and npm path is correctly set

Control Scripts for Windows is under development

For VPS like EC2


  • Server: 1 CPU, 512MB RAM, 5GB Storage
  • System: Ubuntu10.04LTS or CentOS5.5

Swap is required during build


  • Server: 1 CPU, 1GB RAM, 10GB Storage
  • System: Ubuntu16.04LTS or CentOS7

Backend Unit Test

cd api && pytest

Plugin dir


GitHub oauth

GitHub Oauth is supported, please put a configuration file into api/curve/auth/github_oauth.json like this:

  "id": "your github application Client ID",
  "secret": "your application Client Secret"
