> @Thorsten - is there a reasonable way to trigger the issue[...] I really don't know how to manually trigger that issue beyond what is described in the commit message already. I only recognized the problem and reported it after ignoring it in the past.
> A field (which should be displayed as 0.00) was missing in CPU statistics displayed by "sar -u ALL" for tickless CPUs. https://github.com/sysstat/sysstat/commit/c542c259ba9e71a5ade235dfbcde67ac8b510c4f The only relevant things I "customize" in my UBs ist installing the HWE- kernel by following the official docs and storing more SAR files than the default. Everything else regarding especially the kernel is handled by APT and the package maintainers afterwards. Once the HWE-kernel is installed, I simply am using ONLY that as well, didn't ran into problems yet which might have forced me to use the non-HWE ones again. Though, I don't remove those beyond what "apt autoremove" allows me to do. So in the end, things are pretty default in my opinion. The following is the config of sysstat, if it makes any difference. The ".ioconf" file is NOT customized. ``` # sysstat configuration file. See sysstat(5) manual page. # How long to keep log files (in days). # Used by sa2(8) script # If value is greater than 28, then use sadc's option -D to prevent older # data files from being overwritten. See sadc(8) and sysstat(5) manual pages. HISTORY=28 # Compress (using xz, gzip or bzip2) sa and sar files older than (in days): COMPRESSAFTER=30 # Parameters for the system activity data collector (see sadc(8) manual page) # which are used for the generation of log files. # By default contains the `-S DISK' option responsible for generating disk # statisitcs. Use `-S XALL' to collect all available statistics. SADC_OPTIONS="-S DISK" # Directory where sa and sar files are saved. The directory must exist. SA_DIR=/var/log/sysstat # Compression program to use. ZIP="xz" # By default sa2 script generates yesterday's summary, since the cron job # usually runs right after midnight. If you want sa2 to generate the summary # of the same day (for example when cron job runs at 23:53) set this variable. #YESTERDAY=no # By default sa2 script generates reports files (the so called sarDD files). # Set this variable to false to disable reports generation. #REPORTS=false ``` Sometimes I get possibly related error messages from CRON, though: Mail subject: Cron <root@legalxpress> command -v debian-sa1 > /dev/null && debian-sa1 60 2 Mail text: flock: Resource temporarily unavailable -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1921747 Title: Backport missing %gnice CPU value for tickless CPU in sysstat.
