OpsMgr Agents and Gateways Failover Queries

The following article by Jimmy Harper explains very well how to set up agents and gateways’ failover paths thru Powershell https://blogs.technet.com/b/jimmyharper/archive/2010/07/23/powershell-commands-to-configure-gateway-server-agent-failover.aspx . This is the approach I also recommend, and that article is great – I encourage you to check it out if you haven’t done it yet!

Anyhow, when checking for the actual failover paths that have been configured, the use of Powershell suggested by Jimmy is rather slow – especially if your agent count is high. In the Operations Manager Health Check tool I was also using that technique at the beginning, but eventually moved to the use of SQL queries just for performance reasons. Since then, we have been using these SQL queries quite successfully for about 3 years now.

But this the season of giving... and I guess SQL Queries can be a gift, right? Therefore I am now donating them as Christmas Gift to the OpsMrg community

Enjoy – and Merry Christmas!
