OpsCenter 5.0.1 showing high latencies on some metrics

Summary

When viewing some metrics in OpsCenter, the latency figures appear to be higher than normal

Symptoms

When looking at latency metrics such as read / write request latency for nodes the figures appear to be much higher than normal when running tests with a benchmarking tool such as cassandra stress. When using nodetool to check for latency such as "cfhistograms" and "proxyhistograms" the same figures are not seen.

Cause

The problem was caused by a known issue in OPSC-3905 where the metric graphs were reporting the wrong values

Workaround

None available

Solution

Upgrade to OpsCenter 5.0.2 or later
