It can handle transaction logs and > message logs. There are currently two view. > > a) Server view > The server view shows the interactions between the different servers in > an ensemble. The X axis represents time. > * Exceptions show up as red dots. Hovering your mouse over them will > give you more details of the exception > * The colour of the line represents the election state of the server. > - orange means LOOKING for leader > - dark green means the server is the leader > - light green means the server is following a leader > - yellow means there isn't enough information to determine the state > of the server. > * The gray arrows denote election messages between servers. Pink dashed > arrows are messages that were sent but never delivered. > b) Session view > The session view shows the lifetime of sessions on a server. Use the > time filter to narrow down the view. Any more than about 2000 events will > take a long time to view in your browser. > The Y axis represents time in this case. Each line is a session. The > black dots represent events on the session. You can click on the black dots > for more details of the event. > 2 - Compiling & Running > Run "ant jar" in src/contrib/zkgraph/. This will download all dependencies > and compile all the zkgraph code. > Once compilation has finished, you can run it the the zkgraph.sh script in > src/contrib/zkgraph/bin.
