I am also using the performance counter Failed Jobs _Total and I see 3 jobs failed but when I check Activity Monitor I do not see any failed jobs for the past few days...So this _Total is storing every job that failed since the Agent was started or so I am guessing. I only want to see jobs that failed in say the last 24 hours Is there a way this counter can be reset to 0...Restarting the agent doesn't seem to be the best way to reset counters IMHO...
Here is what I am using
perf_counter[\SQLAgent:Jobs(_Total)\Failed jobs]
Any help would be greatly appreciated...
