    Hi Mark, Sorry for the delay. Yes, was able to see the same sort of output using an earlier version of Lustre. In this case: collectl-3.6.7-1.el5 Lustre 1.8.8 2.6.18-308.4.1.el5 CentOS release 5.8 (Final) # cat /proc/fs/lustre/version lustre: 1.8.8 kernel: patchless_client build: jenkins-wc1-gbc88c4c-PRISTINE-2.6.18-308.4.1.el5 # uname -r 2.6.18-308.4.1.el5 # cat...

  • Followup: RE: An attempt to speed-up playback.

    I guess great minds think alike because I've been looking for various ways to speed up playback as well and have also thought of doing a binary search as well but as you said, the existing compression library has not been my friend in this case and so it is good to hear about Gzip::Random. However, there is something else you might be able to do to greatly speed things up and that's to use an...

  • Followup: RE: uninitialized value in string eq colplotlib.p

    Thanks for the info. I'm always happy to hear from people who have discovered the utilities as I personally can't live w/o colplot - that was the main reason I wrote it! Anyhow I honestly have no idea why you're seeing what you're seeing. In an ideal world if you could share the data file causing the uninitialized warning I'd be happy to take a closer look as I'm sure it's related to the...

  • uninitialized value in string eq colplotlib.p

    Hi, I'm running collectl to capture information for specific durations of applications, so I'll just start/stop when a certain query (for example) runs. when I use colplot to create some grapsh, when using "detall", I always get these: Use of uninitialized value in string eq at /usr/share/collectl/colplotlib.ph line 1774, <CFG> line 15. or Use of uninitialized value in...

  • An attempt to speed-up playback.

    Hello Mark and thank you for collectl, Collectl is great. We use it to collect the processes subsys at 60s interval with logs rolling daily at midnight. On a busy host playing back the .raw.gz log file for a time towards the end of the day can take a while, for example below the .gz file is 86MB. time collectl -p /var/log/collectl/hostname-20130428-000000.raw.gz --from=23:55...

    hmm, looking at the code I see collectl looks for a line that looks like LLITE_RPC:x:y data... it expects to see numbers in the 1st and 5th fields of the data portion, noting the indexing starts at 0. from what I can see above the the entroes for 0:0 and 0:1 don't even look like each other and I guess I have to ask if the people who bring us lustre have changed the format of that data. do...

    Hi Mark, As others have said, you've really produced a fantastic tool here. Lots and lots of uses for it - especially enjoying using it with Lustre. BTW, I should clarify that this report applies *ONLY* when running the command/options on a Lustre client. When using the same options and running on an OSS, it works as expected. Thanks again, Brett.
