Selenograph is a powered version of Selenium Grid Router providing more information about currently running Selenium sessions and hubs state. With this information Selenograph finds available browser faster and provides data for the real time status and statistics.
Unlike the original Grid Router, Selenograph has the shared state between nodes, which is stored in database. We use MongoDB as a database, because it provides high availability, fault tolerance and schema-less approach. Although it's recommended to use a replica set (at least 3 nodes of MongoDB), you can run just a single instance to play with Selenograph.
- Web interface displaying all available quotas, browsers and versions with the corresponding number of currently running sessions
- REST API showing information about currently running sessions for each quota and hub
- Ability to export to Graphite e.g. in order to visualize quotas and browsers usage statistics
For Ubuntu users we provide deb packages. Please note that yandex-selenograph package conflicts with yandex-grid-router, so if you have previously installed Selenium Grid Router, you'll need to uninstall it first.
Also ensure that you have Java 8 installed:
$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update
$ sudo apt-get install oracle-java8-installer
To install Selenograph itself:
$ sudo add-apt-repository ppa:yandex-qatools/selenograph
$ sudo apt-get update
$ sudo apt-get install yandex-selenograph
$ sudo service yandex-selenograph start
You can also run Selenograph in Docker container (not yet available - coming soon):
$ sudo docker run --net host \
--log-opt max-size=1g \
--log-opt max-file=2 \
-v /etc/grid-router:/etc/grid-router:ro \
-v /var/log/grid-router:/var/log/grid-router \
-d qatools/selenograph:latest
Most of configuration options duplicate the original Selenium Grid Router ones.
To configure the MongoDB connection and other Selenograph-specific options, you should edit /etc/grid-router/selenograph.properties:
##### Main MongoDB options: #####
# Specifies the mongodb hosts
camelot.mongodb.replicaset=localhost:27017
# Set the database name for selenograph
camelot.mongodb.dbname=selenograph
# Set the username for selenograph user
camelot.mongodb.username=
# Set the password for selenograph user
camelot.mongodb.password=
##### Graphite export options: #####
# Specifies the graphite api host (uncomment to enable)
# graphite.host=127.0.0.1
# Specifies the graphite api port
# graphite.port=42000
# Specifies the prefix for metrics
# selenograph.gridrouter.graphite.prefix=selenograph
##### Advanced MongoDB options: #####
# The following options are not recommended to change
# Edit them at your own risk only if you want to configure the connection options
# camelot.mongodb.connections.per.host=30
# camelot.mongodb.threads.connection.mult=40
# camelot.mongodb.connect.timeout=15000
# camelot.mongodb.heartbeat.timeout=15000
# camelot.mongodb.heartbeat.frequency=1000
# camelot.mongodb.heartbeat.socket.timeout=10000
# camelot.mongodb.readpreference=PRIMARY_PREFERRED
# camelot.mongodb.socket.timeout=60000
# camelot.mongodb.waitForLockSec=120
# camelot.mongodb.lockPollMaxIntervalMs=7
Requires Basic HTTP authorization with quota credentials. Shows information about browsers available in current quota. Output example:

}
Requires Basic HTTP authorization with quota credentials.
Returns usage statistics for each browser version for quota. max and avg numbers displays the maximum and average
concurrent sessions during current minute. raw and current displays the currently running sessions count.
Output example:
{
"selenium:firefox:36.0":{
"max":0,
"avg":0,
"raw":0,
"current":0
},
"selenium:chrome:41.0":{
"max":0,
"avg":0,
"raw":0,
"current":0
},
"selenium:firefox:37.0":{
"max":0,
"avg":0,
"raw":0,
"current":0
},
"selenium:firefox:38.0":{
"max":0,
"avg":0,
"raw":0,
"current":0
}
}
A ping API for load balancers. Returns 200 when service is functioning properly.
Shows a list of all available hubs with percentage of free browsers (100% for completely free hub). This information is used while selecting the next hub to route the session to. Output example:
{
"lastUpdated":"Feb,26 12:39:13.061",
"hubs":{
"firefox33-1.selenium.net:4445":100,
"firefox33-2.selenium.net:4445":75,
"firefox42-1.selenium.net:4445":50,
"firefox42-2.selenium.net:4445":100,
"chrome45-1.selenium.net:4444":80,
"firefox38-1.selenium.net:4445":100,
}
}
Shows information about all available quotas: which browser versions exist and how many browsers are available for each version. This info is actually the mirror of the configured Gridrouter quotas enriched with currently running sessions count.
