Description The JMX plugin is a Nagios plugin for monitoring devices, applications, and service-driven networks using Java Management Extensions (JMX).
JMX is a Java technology that supplies tools for managing and monitoring applications, system objects, devices, such as printers, and service oriented networks. Those resources are represented by objects called mbeans (for managed bean).
JMX exposes a set of mbeans which represent a resource running in the Java Virtual Machine.
The JMX implementation of a Java application server typically exposes resource usage statistics (such as memory or threads used) and lots of other statistics and metrics. Apart from generic information, the application server vendor also provides mbeans specific to the application server in question.
The check_jmx plugin enables you to monitor the values of any mbean attribute made available through JMX.

Description Checks the status of VMware ESX 3.x, ESXi server, vSphere 4 and vSphere 5.
Why? Checks the status (CPU, memory, runtime, and others) of virtual machines running inside VMware ESX server, VMware ESX hosts, and vSphere infrastructure.
How? Queries the status of ESX server or vSphere using the vi(vSphere) Perl API.
Supported platforms VMware ESX server, VMware ESXi server, VMware vSphere infrastructure
Categories Operating systems
Support Level Level 8 (deprecated)
This plugin has been deprecated in favor of check_vmware_v2.

check_vmware_v2

Commands check_vmware_v2_esxi_host, check_vmware_v2_esxi_host_no_ssl, check_vmware_v2_vcenter_host, check_vmware_v2_vcenter_host_no_ssl, check_vmware_v2_vcenter_vm, check_vmware_v2_vcenter_vm_no_ssl check_vmware_v2_vcenter_cluster, check_vmware_v2_vcenter_cluster_no_ssl, check_vmware_v2_vcenter_datacenter, check_vmware_v2_vcenter_datacenter_no_ssl
Description Checks the status of VMware vSphere infrastructure.
Why? The plugin can be used to monitor the infrastructure managed by a VMware vCenter server or a VMware ESXi server, such as its data centres, clusters, hosts, and virtual machines. It can check a large range of different metrics and statuses, depending on the targeted infrastructure; for example CPU load, memory usage, network activity, and runtime states.
How? The plugin requires a separate service to run on the OP5 Monitor host. The plugin talks to the service which in turn talks to the target vSphere API server. The plugin service uses the pyVmomi vSphere API Python bindings from VMware to talk to the VMware vSphere infrastructure.
Supported platforms VMware vSphere infrastructure: VMware vCenter and VMware ESX and ESXi hypervisor hosts.
The plugin uses pyVmomi 6.7.1, which means that it fully supports vSphere 6.7.1, 6.7, 6.5 and 6.0.
