-----------------------------------
Summary: %CPU always reports 0 for managed reservations
Key: UIMA-5647
URL: https://issues.apache.org/jira/browse/UIMA-5647
Project: UIMA
Issue Type: Bug
Components: DUCC
Affects Versions: 2.2.1-Ducc
Reporter: Eddie Epstein
Fix For: future-DUCC
%CPU reporting works for service and job processes, but not managed
reservations.
To reproduce the problem, create a bash script, say eatcpu.sh:
#!/bin/bash
while true; do for f in $(seq 1 100000); do echo 555 > /dev/null; done; done;
and then run it viaducc:
$DUCC_HOME/bin/viaducc eatcpu.sh
The duccmon reservation details page always shows %CPU=0, but top shows
something just under 100%
