The rather shaky vbox console monitoring we had has been completely rewritten by computezrmle to look much better, both the event progress monitoring and the "top" resource usage monitoring. Console 2 (ALT-F2) now looks like this: and Console 3 (ALT-F3) is now interactive version of "top" without the scrolling and flickering that affected it before. For example you can hit the space bar to get an immediate update of information or type "u" then "atlas" to see only processes from the atlas user. The changes will be active in the next couple of hours. Thanks again to computezrmle for this great work! |

Console 2 (ALT-F2) now looks like this: Time left (rough estimate) : 4d 5h 21m |

Console 2 (ALT-F2) now looks like this:Time left (rough estimate) : 4d 5h 21m Anything wrong with it? What are the corresponding values for: "Total # of events to be processed" "Total # of events already finished" The algorithm currently used is experimental and does not deliver good estimates if - only very few events are finished - VMs are paused for longer periods A new version that uses a better algorithm is under development and should be ready next week. |

Nothing wrong. The other 4 threads are busy too, so ATLAS don't get the most possible power.Anything wrong with it?Console 2 (ALT-F2) now looks like this:Time left (rough estimate) : 4d 5h 21m - only very few events are finishedThat was the case ;) Only 2 events were done, so 2 other events halfway done were not counted. Now with 8 events done the estimate time left is down to 2 days and 2.5 hours. Go on with your excellent work. Not that it's a real issue, but the averages/worker seems a bit strange in the beginning. After 1 event and 2 events it's the same value. Don't spend to much time on it. |

Not that it's a real issue, but the averages/worker seems a bit strange in the beginning. This is caused by the fact that the monitoring user is not allowed to directly read anything from the atlas directories. Even if it could - ATLAS doesn't provide an interface where you can get the estimated runtimes for a currently running event. Instead ATLAS reports finished events to it's logs and a helper program dumps that information to a file that is readable by the monitoring user. The main reason to do it this way is to leave the ATLAS app completely untouched. So even with the announced 2nd monitoring version there will be jumps regarding the time left estimation. |

Since last night ATLAS (vbox) uses v2.2.0 of ATLAS Event Monitoring. It includes the following changes: - Modified display layout - Change requests made by Crystal Pellet are implemented: https://lhcathomedev.cern.ch/lhcathome-dev/forum_thread.php?id=497&postid=6795#6795 - A modified "time left" algorithm that avoids using the precalculated averages from the logfiles. Wrong values from the logfiles are still printed "as is" in the worker lines. - Foreground service (display output) and background service (logfile dumping) are tied together to allow a restart of the complete monitoring when CTRL-c is pressed at console 2. |

Crystal,Of course. It's on imgbb.com without account, so I'm not sure whether it will stay for ever. |

Version 3.2.0 of Console ALT-F2 (Event Monitoring) is active. Thank you, computezrmle ! Example how the new monitoring looks like when running with 4 CPUs: |
