Will parse the admin-webpage, and check number of trackers, blacklisted nodes, heap size and more.
Will output performancedata for nodes, blacklisted nodes, running jobs (map and reduce), capacity jobs (map/reduce) and heap size (used/max)
I made this little script, to parse output from the adminpage, normally found at http://jobtracker.company.com:50030/jobtracker.jsp
It will check for status, and number of machines, and also give performanceoutput.
Nagios-config would look something like this;
define service{
use generic_service
service_description Jobtracker
check_command check_jobtracker
hosts jobtracker.company.com
}
define command{
command_name check_jobtracker
command_line $USER1$/check_hadoop_jobtracker.pl -H jobtracker.company.com -w 50 -c 40 -b 1 -p 50030
}
Plugin takes these options:
