JVM uptime less than JAVA process uptime?


(Nelson Jeppesen) #1

I'll keep this short and I hope its just a misunderstanding of java on my
part.

All my Elasticsearch nodes are reporting a JVM uptime between 1 and 25
hours. The strange part is all the JAVA process have a start date of 9+
days. How can the JVM uptime be less than the JAVA process time? I see
nothing in the Elasticsearch logs with any indication of the issue. Thanks
for your help.

At a guess, it might mean the actual time it spent processing, as opposed
to service runtime.

I was thinking the same thing, except every ~25 hours the jvm uptime resets
back to zero, but the java pid and start time remain unchanged.
