Hi, I have put together a perl module named 'Net::ZKMon', a wrapper module around the ZooKeeper's 4-letter word commands meant for zookeeper monitoring.
This module is written and meant to the serve the purpose of - providing a perl interface to executing 4-letter command as just another perl function, - having the monitoring data in a structured perl references - and attempting to reduce the pains/overhead/hassle involved in parsing the entire monitoring data when the 4-letter words are executed. This is a very initial bare-bones release seeding the thought of wrapping around the monitoring with perl's style of doing things. Its in a very nascent stages with incomplete set of documentation as of yet, however I hope to see it being used as a plugin module required for other sorts of monitoring systems like collectd/nagios/ganglia/cacti (for both alerting & graphing) for monitoring Zookeeper, with full documentation soon. The package will also get to have more examples for easier integration with general monitoring systems. About Apache ZooKeeper 4-letter words/commands : http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_zkCommands Source of the code is available and published at http://search.cpan.org/~mnikhil/Net-ZKMon/ I am also open for the ideas/suggestions/ improvements/collaboration. Please feel free to fork the code yourself at github here : https://github.com/mnikhil-git/p5-Net-ZKMon An Example: =========== #!/usr/bin/perl use strict; use Net::ZKMon; my $hosta = 'host1.prod.mycompany.com'; my $hostb = 'host2.prod.mycompany.com'; my $hostc = 'host3.prod.mycompany.com'; my $hostd = 'host4.prod.mycompany.com'; my $hoste = 'host5.prod.mycompany.com'; my @zcluster = ( $hosta , $hostb , $hostc, $hostd, $hoste ); my $zkmon = new Net::ZKMon(hostname => $hosta); print $hosta, ": version : ", $zkmon->stat->{'version'}, "\n\n"; foreach my $h (@zcluster) { my $h_srvr = $zkmon->stat($h); print "Node: $h --> $h_srvr->{version} | $h_srvr->{Mode} | $h_srvr->{Zxid} | $h_srvr->{'Node count'} ", " | $h_srvr->{min_latency} | $h_srvr->{max_latency} | $h_srvr->{avg_latency} \n"; } Output: host1.prod.mycompany.com version : 3.3.4 Node: host1.prod.mycompany.com --> 3.3.4 | follower | 0x50003ad60 | 18 | 0 | 753 | 0 Node: host2.prod.mycompany.com --> 3.3.4 | follower | 0x50003ad60 | 18 | 0 | 53 | 0 Node: host3.prod.mycompany.com --> 3.3.4 | follower | 0x50003ad60 | 18 | 0 | 9 | 1 Node: host4.prod.mycompany.com --> 3.3.4 | follower | 0x50003ad60 | 18 | 0 | 752 | 0 Node: host5.prod.mycompany.com --> 3.3.4 | leader | 0x50003ad60 | 18 | 0 | 252 | 0 Thanks, Nikhil
