Monitoring Virtual Machines in PCF

Page last updated:

This topic describes strategies for monitoring virtual machine (VM) status and performance in Pivotal Cloud Foundry (PCF).

Monitoring VMs Using the Ops Manager Interface

Click any product tile and select the Status tab to view monitoring information.

The columns display the following information:

VM Data PointDetails
JobEach job represents a component running on one or more VMs that Ops Manager deployed.
IndexFor jobs that run across multiple VMs, the index value indicates the order in which the job VMs were deployed. For jobs that run on only one VM, the VM has an index value of 0.
IPsIP address of the job VM.
CIDUniquely identifies the VM.
Load Avg15CPU load average over 15 minutes.

Operations Manager VM Disk Space

The Ops Manager stores its logs on the Ops Manager VM in the /tmp directory.

Note: The logs collect over time and do not self-delete. To prevent the VM from running out of disk space, restart the VM to clear the log entries from /tmp.

Monitoring in vSphere

To monitor VMs using the vSphere client:

  1. Connect to a vCenter Server instance using the vSphere client.
  2. Navigate to the Hosts And Clusters or VMs And Templates inventory view.
  3. In the inventory tree, select a virtual machine.
  4. Select the Performance tab from the content pane on the right.

VMware vSphere Server provides alarms that monitor VMs, as well as clusters, hosts, datacenters, datastores, networks, and licensing. To view preconfigured alarms, including disk usage alarms, related to a particular VM:

  1. In the vSphere client, select the VM you want to monitor.
  2. At the bottom left of the client window, click Alarms.
  3. If a VM starts to run out of disk space, an alarm appears in the bottom panel.
