can't install direct agent
I uninstalled the Advisor Agent and Gateway on my Config Mgr server, hoping to take advantage of the new Direct Agents to monitor something besides the same 8 red-herring alerts I get every single week from Advisor - and I can't install it; the Direct Agent states it can't be installed because Advisor is present - but I just uninstalled the Advisor agent and gateway.
I'm out. This whole thing has gone goofy with Ops Mgr integration and agents and gateways. We're a small IT shop and I don't have time to figure out Ops Mgr in addition to the 1000 other jobs I have to do.
We indeed intended to simplify – you can now use just the direct agent, with no need for OpsMgr and also don’t need a specialized Gateway. The agent can also be configured to talk thru proxies (there is a powershell example here http://technet.microsoft.com/en-us/library/dn500848.aspx).
This said, System Center does bring some additional capabilities if you have it and use it in combination with OpInsights, but with Direct Agent we meant to not make it a requirement, precisely to simplify on-boarding and reduce the infrastructure footprint for those – like yourself – who don’t use System Center.
I also attempted the procedure today (albeit this had already been tested): I just took an old machine that had the OpsMgr 2012 SP1 agent and the advisor gateway on it; I un-installed the gateway; rebooted; installed the new Direct Agent MMA package (which upgraded the one already on the machine), rebooted again; configured it, and now it is reporting data to the service just fine.
Anyhow, I have reached out to you in email if you need help with uninstalling/reinstalling in your environment and you are getting some kind of error we’d love to look at it and help you out and answer any other question around OpInsights you might have.
Hope that helps,
