  • RCR - Total reporting containers
  • CPU% - Total CPU percent consumed by all containers
  • MEM - Total memory used by all containers
  • DISK - Total disk used by all containers
  • RESP - Avg response time in milliseconds over last 60 seconds
  • LOG_OUT - Total number of stdout log events
  • LOG_ERR - Total number of stderr log events
  • REQ/1 - HTTP(S) request/responses in last 1 second that have gone through go-router

  • FREE_MEM -
  • C_RSVD_MEM -
  • C_USD_MEM -
  • TOT_DISK -
  • FREE_DISK -
  • C_RSVD_DSK -
  • C_USD_DSK -
  • MAX_CNTR -
  • CNTRS - Number of containers cell thinks it has running
  • DNAME - BOSH deployment name

Installation

There are two options for installation; use the plugin repo (recommended) or manual installation.

NOTE: This installation method requires that your client computer has access to the internet. If internet access is not available from client computer use the manual method.

Verify you have a repo named CF-Community registered in your cf client.

cf list-plugin-repos

If the above command does not show CF-Community you can add the repo via:

cf add-plugin-repo CF-Community http://plugins.cloudfoundry.org/

Now that we have the cloud foundry community repo registered, install top:

cf install-plugin -r CF-Community "top"

Manual installation method

  • Download the binary file for your target OS from the latest release
  • If you've already installed the plugin and are updating, you must first run cf uninstall-plugin top
  • Then install the plugin with cf install-plugin top-plugin-darwin (or top-plugin-linux or top-plugin.exe)
  • If you get a permission error run: chmod +x top-plugin-darwin (or top-plugin-linux) on the binary
  • Verify the plugin installed by looking for it with cf plugins

Upgrade to latest version

To upgrade to the lastest version of top plugin, uninstall plugin and install again.

cf uninstall-plugin top
cf install-plugin -r CF-Community "top"     (or use manual install method described above)

Assign needed permissions (if not using admin user)

To use this plugin you must be logged in as 'admin' or assign two permissions to an existing cloud foundry user. To assign needed permissions:

Install the uaac client CLI if you do not already have it:

gem install cf-uaac

Login and add two permission. Note that the UAA password is NOT the "Admin Credentials", the password is found in the ERT under Credentials tab, look for password for "Admin Client Credentials".

uaac token client get admin -s [UAA Admin Client Credentials]  
uaac member add cloud_controller.admin [username]
uaac member add doppler.firehose [username]

Note: The change in permissions does not take effect until user username performs a logout and login.

Usage

User must be logged in as admin or cloud foundry user with permissions as described above. The plugin does not require any arguments. Simply run:

cf top
