It is crucial to know the state of your machines. AppMon provides zero-configuration host health monitoring — every installed Agent automatically delivers Host Health information. The Agent collects information about CPU, memory, disk and network interface utilization to determine the host system's health state.
The Node.js Agent does not deliver host monitoring data. Use the Host Monitoring Agent if you only have the Node.js Agent on the machine.
The Web Server Master Agent does not deliver host monitoring data on its own. There must be at least one Web Server Slave Agent or a Host Monitoring Agent.
Configure hosts, thresholds, and alerts at the Infrastructure item of the Dynatrace Server Settings dialog box.
You can view host monitoring data:
- In the AppMon Web: Host health web view.
- In the AppMon Client: Infrastructure Monitoring built-in dashboard.
What is monitored on what platform?
|Processor||CPU User Time|
|CPU System Time|
|CPU Load||Unix Load Average (exponential moving) average of running processes per minute.|
|Page Faults1||Hard page faults only|
|Disk||Disk Storage Utilization2||Free disk space and percentage of available space|
|I/O Statistics2||Read/write statistics of physical disks|
|Network||Network Inbound Utilization3||Percentage of used inbound bandwidth|
|Network Outbound Utilization3||Percentage of used outbound bandwidth|
1 Requires disk access permissions to the disks that contain the swap partition or swap file.
2 Requires read and list files permissions to the disks that are to be monitored. Mapped network drives are excluded by default from Disk Storage Utilization.
3 On *NIX systems a kernel with version greater or equal to 2.6.33 is required otherwise only the transfer rates are displayed.
4 zOS is not supported currently.
CPU core count on AIX LPAR
CPU core count is only determined during agent startup.
CPU core count = "Maximum Virtual CPUs" * SMT-Factor according to "lparstat -i".
OS virtualization and container monitoring
VMware, Xen and Hyper-V are detected and supported. See VMware for more information.
VirtualBox is detected, but not supported.
Some operating system level virtualization techniques on various Unix/Linux based systems like Solaris Zones, OpenVZ, BSD Jails and VServer are not supported. Agents running within a container report metrics from the operating system and the instrumented applications, but not from the container management (tools).
