Summary: Inconsistency between mesos master UI and mesos slave /metrics/snapshot Key: MESOS-3156 URL: https://issues.apache.org/jira/browse/MESOS-3156 Project: Mesos Issue Type: Bug Components: master, slave, statistics, webui Affects Versions: 0.22.1 Environment: Test environment runs on vagrant Master: Centos 7 + mesos 0.22.1 + marathon 0.9.0 = 1 vcpu + 1gb ram Slave: Centos 7 + mesos 0.22.1 = 3vcpus + 2048mb (1 master + 1 slave) Reporter: Sebastian Otaegui We recently began doing some tests with kibana to graph some of the stats of the slaves and the masters. We found something pretty odd: Test case: In my example my slave has 1840 mb free, of which mesos reserves 920mb for tasks. 1. create N (in my case 14) marathon tasks with the following configuration {noformat} command: while true; do sleep 1 ; echo "heloo"; done mem: 64mb cpu: 0.1 {noformat} 2. check the mesos master web UI {noformat} Total 3 920 MB Used 1.4 896 MB {noformat} 3. check the <slave host>:5051/metrics/snapshot {noformat} "slave/mem_total":920, "slave/mem_used”:1344 {noformat} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
