TSquare is the Time Series Query, Reporting and Exploration tool. It offers an extended HTTP-based API for use with OpenTSDB v2.0.x. In particular, TSquare includes (currently) limited support for Graphite's render API. Other features include:
- Extended JSON query response format, including support for JSONP responses
- A grep endpoint that allows you to search over metric names and tags using regular expressions and/or wildcards
- Aggregator factory that allows lookup of aggregators based on metric name (e.g by regex and/or wildcard)
- Extended metric query format that allows for default and auto-assigned aggregators (used in concert with the aggregator factory)
- Last value aggregator (which is going to be added to OpenTSDB v2.1)
N.B. We wrote TSquare before OpenTSDB v2.x was available. OpenTSDB v2 has an extended REST API itself, so you might notice some overlap in features. It's very likely that we will port the unique features of TSquare over to OpenTSDB v2 soon.
To build TSquare you'll need:
- Java 1.6+ and
- Maven 3.x
- OpenTSDB v2.0.x (see below)
Because OpenTSDB is not in any public Maven repository you'll need to download and build it yourself. Luckily, it's very easy. Just follow the building instructions on their Installation page.
At this point, you should have successfully built OpenTSDB. The next step is to build it with Maven and install the artifact in your local Maven repository. Here's how:
## from within the OpenTSDB base directory (the one with build.sh in it)
cd build
make pom.xml
cd ..
mvn clean install
Now you are ready to build TSquare, which builds as a .war file:
## from with the TSquare base directory
mvn clean package
The resulting artifact is: target/tsquare.war
Building using Docker
We've included a Dockerfile that makes building TSqure really easy. Assuming you already have Docker installed and running you can generate the WAR with two commands:
docker build -t="tsquare:v2" .
docker run -i -t tsquare:v2 > tsquare.war
To run TSquare you'll need servlet container like Tomcat or Jetty. (We've only tested TSquare with Tomcat.) Just deploy it as per the requirements of your specific container.
The initial version of this application was written by James Royalty.
