• Dublin release - made good process for the past couple of weeks but still waiting for the release notes update from 3 teams
  • After some effort for the past week or so, logging project (include POMBA) is good for Dublin sign-off
  • El Alto will be “Reduce Internal Debt” release, will be grooming the backlog within this week.  
  • POMBA Dublin Demos
  • use cases to showcase the capability of logging and logging specification (please use the comment section for your ideas)

  • Prudence Au not available today.
  • Reviewed Lorraine's analysis of POMBA logs:
    • An encouraging number of attributes populated.
    • InvocationID possibly unset.
    • Looked like the provider config still explicitly specified MDCs by name with %X{name}, so that's a pre-Amsterdam configuration.
  • Canonical examples:
    • No truly canonical examples. POMBA is probably among the best.
    • We've had past success identifying flows from SO/APPC/SDNC output:
      • What they execute is of interest in analytics (in a way that SDC, for example, is less interesting). 
      • It took a lot of finessing, though, to allow for differences in naming, missing data, etc.
      • Action on Luke Parker to do a little analysis and summarize at the next meeting.
    • Regarding what canonical looks like:
      • The spec:
        • Is still daunting. 
        • Understandably nobody is eager to reopen this issue.
        • But it probably couldn't hurt to separate out and emphasize the 1/3 (~10) or so that are critical.
      • The pipeline:
        • Filebeat was meant to be temporary, in response to:
          • EELF, and no authority to bypass logfiles.
          • Heterogeneous logging provider types and versions.
          • The impossibility of getting fancier transports into the classpath for every provider in every Java runtime in every container. 
        • But if we can reconfigure the pipeline, then:
          • The output format won't necessarily matter, because we can ship logs in a structured format: syslog, logstash, JSON, etc. 
          • Then Filebeat can be optional, and maybe can even cease to be enabled by default.
          • This has a much better ROI than fussing over formats. 
          • (It's noteworthy that we've made it so far without even minimal extension points).
        • Spoke to Borislav Glozman and Mike Elliottand Avi Chapnick from  OOM about this: 
          • About making the Filebeat sidecar optional in deployment manifests. 
          • About allowing provider configuration docs to be replaced (and thereby to enable other transports):
            • Individually. 
            • En masse. 
          • And their response was that they're working on generating manifests, which:
            • Could allow these kinds of changes to be made without nearly so much busy work. 
            • But which also means coordination and delays. 
          • Should try to get Mike Elliott along next time.
  • Next meeting: July 9, 2019

  • No labels
