"description": "h1. ZooKeeper top\n\n*Author: \"Patrick Hunt\":http://people.apache.org/~phunt/* (follow me on \"twitter\":http://twitter.com/phunt)\n\nh2. Summary\n\n\"This project\":http://github.com/phunt/zktop provides a unix \"top\" like utility for ZooKeeper. It is compatible with Python2.6, Python2.7 and Python3.\n\nh3. Example\n\nRunning:\n\n\n./zktop.py --servers \"localhost:2181,localhost:2182,localhost:2183\"\n
\n\nor - omitting the port numbers, defaulting to 2181 -\n\n\n./zktop.py --servers \"server1,server2,server3\"\n
\n\nor, for a ZK-style configuration file:\n\n\n./zktop.py --config zk.conf\n
\n\nshows a screen like:\n\n\nEnsemble -- nodecount:10 zxid:0x1300000001 sessions:4\n\nSERVER PORT M OUTST RECVD SENT CONNS MINLAT AVGLAT MAXLAT\nlocalhost 2181 F 0 93 92 2 2 7 13\nlocalhost 2182 F 0 37 36 1 0 0 0\nlocalhost 2183 L 0 36 35 1 0 0 0\n\nCLIENT PORT I QUEUE RECVD SENT\n127.0.0.1 34705 1 0 56 56\n127.0.0.1 35943 1 0 1 0\n127.0.0.1 33999 1 0 1 0\n127.0.0.1 37988 1 0 1 0\n
\n\nh3. What's Apache ZooKeeper?\n\n>From the \"official site\":http://hadoop.apache.org/zookeeper/: \"ZooKeeper is a high-performance coordination service for distributed applications.\"\n\nIt exposes common services - such as naming, configuration management, synchronization, and group services - in a simple interface so you don't have to write them from scratch. You can use it off-the-shelf to implement consensus, group management, leader election, and presence protocols.\n\nh2. zktop.py\n\n0) Top line is overall cluster status\n1-n) Lines 1-n are for the n servers\nn+1 and below are for client connections\n\nh3. Usage\n\n\nUsage: zktop.py [options]\n\nOptions:\n -h, --help show this help message and exit\n --servers=SERVERS comma separated list of host:port (default\n localhost:2181)\n -n, --names resolve session name from ip (default False)\n --fix_330 workaround for a bug in ZK 3.3.0\n -v VERBOSITY, --verbosity=VERBOSITY\n log level verbosity (DEBUG, INFO, WARN(ING), ERROR, CRITICAL/FATAL))\n -l LOGFILE, --logfile=LOGFILE\n directory in which to place log file, or empty for\n none\n -c CONFIGFILE, --config=CONFIGFILE\n zookeeper configuration file to lookup servers from\n
\n\n--fix_330 works around a bug in ZooKeeper 3.3.0, it is only necessary if running the server against that version of ZooKeeper.\n\nThe screen refreshes every 3 seconds.\n* 'h' help\n* 'q' quits\n* 'r' resets the server stats\n* spacebar updates immediately\n\nh2. PyPi\n\nzktop is now installable from PyPi\n\n\npip install zktop\n
