The following image shows client failed requests and JMS messages per server when all the WebLogic servers fail on a site. Time to live (TTL) equals 120 seconds, and downtime is approximately three minutes.

This image includes two time-series graphs that correlate Oracle WebLogic Server (WLS) request failures with Java Message Service (JMS) queue growth.

Both graphs use the same x-axis, Time, and their trends align to show that the failure surge coincides with rising JMS queue counts during the same period.

The first graph is titled “Requests Failed / sec.” The y-axis label is “Trans Failed/sec.” The x-axis label is “Time.” The failure rate increases during the outage and then clears.

The second graph is titled “JMS MessagesCurrent count per server's FOD queue.” The y-axis shows message counts from 0K to 8K. The x-axis label is “Time.” Multiple per‑server series rise during the outage and continue afterward.

At outage start, the call-out text states “When the WLS servers in region 1 are killed (outage starts).” At that instant, failures begin on the first graph and JMS queue counts start increasing on the second graph. At outage end, the call-out text states “When all the requests are redirected to region 2 (outage ends).”
