Management Credentials

I got a question about the Management Credentials that are used for managing assets in Ops Center:

"If I change a set of credentials, does Ops Center propagate the changed credentials to all of the assets that use that set?"

The answer is yes.

To provide some additional explanation: each managed asset is linked to Management Credentials that are used to access it. You can have separate Management Credentials for every asset, or share one set for a group of assets that all have the same login credentials. If you change the credentials on the systems, you can edit the Management Credentials to make sure they match the new system creds. Any asset that's using that set of credentials will then automatically start using the new set.

The Feature Reference Guide has a section about Management Credentials that explains how to perform these procedures.

Which Proxy Controller is managing your assets?

I got an interesting question about Proxy Controllers. The question was, if you have an asset on a network and two Proxy Controllers can access that network, can you control which Proxy Controller manages the asset?

Well, you do have some control, but before I get into that, it's worth noting that the Proxy Controller-Agent communication works differently in 12c than it did in prior versions of Ops Center. In older versions, an Agent was associated with one specific Proxy Controller, and if the Proxy Controller failed the asset's connection to Ops Center was broken. In 12c, if a Proxy Controller fails, you can migrate the assets to any other Proxy Controller with access to their network, keeping the assets managed.

So, in 12c assets are not as strongly tied to specific Proxy Controllers. When you try to discover an asset, Ops Center looks at which Proxy Controllers can access the asset, and picks the one with the least load.

However, you do have some options for controlling what asset goes to what Proxy Controller. First, you can put a Proxy Controller into maintenance mode by selecting the Proxy Controller and clicking Put in Maintenance Mode; this doesn't stop it from managing its existing assets, but it stops it from taking on new ones.

You can also set different power levels for your Proxy Controllers. Select the Enterprise Controller's Configuration tab, then select the Proxy Management subsystem. If you want Proxy Controller A to do twice the work as Proxy Controller B, for instance, set A's relative power to 2 and B's to 1.

The Feature Reference Guide goes into more detail about discovery, and the Administration Guide gives you more information about Enterprise Controller settings and asset migration.
