It is an easiest way to implement SNMP monitoring over Hadoop cluster.
jmxterm is used to retrieve information from JMX mbeans. See official home page. RPM is available here.
The package consists of several parts: * schema processor and default schema for it * mib generator * subagent-shell function and configuration * cli utility to work with jmxterm
The utility can be used aside from subagent or SNMP. It produces ini-like output parceable with anything:
`
hadoopYarnResourceManagerContainersPending = 18
hadoopImpalaCatalogTcmallocTotalBytesReserved = 95830016
hadoopYarnResourceManagerSchedulerQueuePendingApps.1877334299 = 0
`
Values the utility prodoces are configured through schema. You can find default one in
`monitoring/data/schema`. Default service ports are configured in `data/monitoring/locator.yml`
