Listing deployed agents with a Controller

Controllers are listing Spider agents deployed in the (remote) cluster.

Namespace whitelist and blacklist from Controller infrastructure configuration also apply to these lists.
You may keep some namespace hidden... Or deploy a different Controller for different namespace(s).

Attachments tab​

The attachment tab lists all attachments configured for this Controller.

Attachments are collapsed by default, click on the title to expand them.

You know:

  • Who created the attachment
  • Its status
  • On what Whisperer
  • What Agent (Gossiper or Whisperer)
  • Its target
  • The count and list of current Whisperers instances deployed, if any

You can:

  • Create another attachment
  • Detach an existing attachment
  • Refresh the tab

List of instances​

The list of instances lists the deployed Whisperers for each attachment.

You have access to:

  • The POD name
  • The Whisperer state
    • waiting
    • running
    • terminated
  • The Whisperer uptime, with a tooltip containing
    • Its started date
    • The reason for its status - for waiting and terminated statuses
    • And for terminated statuses
      • Its finished date
      • The errorCode
      • The detailed message

You may also:

  • Access the last 100 log events from the Whisperer
  • Filter on this Whisperer

Sidecars tab​

The Sidecars tab lists all Whisperers deployed as Sidecars in the cluster.

Sidecars are collapsed by default, click on the title to expand them.

You know:

  • The Whisperer
  • What Agent (Gossiper or Whisperer)
  • Its target
  • The count and list of current Whisperers instances deployed, if any

The list of instances is similar as for the Attachments tab, with the same features.

Gociphers tab​

The Gociphers tab lists all Gociphers deployed (as daemonsets) in the cluster.

As there is usually only one Gocipher, there is no collapse feature ;)

You find:

  • The Gocipher
  • Its namespace
  • Its linked Controller
  • And the list of its instances. One by node in the cluster.

You may also access the Gociphers logs as for the Whisperers.

Agents logs​

When clicking on the terminal icon, the Controller fetches the last 100 logs of the related agent, and displays them on the UI.
As Spider logs are in JSON, they are formatted nicely, and common fields are grouped at the top.

Should you want complete access to the log item, for troubleshooting, you may open it via the Raw link at the right:

It opens the log as a JSON with color highlighting, folding and search features.
