Zkgraph is a log viewer for zookeeper. 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.

[jira] Commented: (ZOOKEEPER-740) zkpython leading to segfault on zookeeper

Mike Solomon commented on ZOOKEEPER-740:
The common cases is when you supply a watcher for a get().
Start a zk server on localhost and create a node /zk.
Connect a python process like this:
import sys
import zookeeper
zh = zookeeper.init('localhost:2181')
def _zk_callback(*args):
print sys.stderr, _zk_callback, args
zookeeper.get(zh, '/zk', _zk_callback)
Kill the zk server. The client will idle fine. When restarting the zk server, I
get a SIGSEGV on reconnect 100% of the time.
This is fixed by the following patch:
