Grok Filtering the Logstash Plugin on Jenkins

I saw that come through today, and my first thought was "spam!" I mean, really? Visions of Michael from Mars and Leroy Jenkins hiding their stash under a log somewhere. I was so close to pressing that "Alert Moderator" button, when from the corner of my eye I saw "logstash" in the blog post on which this comment appeared.

Then I saw "Jenkins."

It turns out there is a product called Jenkins that runs in SAP Cloud Platform, and there's a plugin for it called Logstash, and there's another feature called a Grok filter. I kid you not.

What the heck is a Grok filter, you might ask? If you've read Stranger in a Strange Land by Robert A Heinlein, you'll be familiar with this word, but how does it bear here? Apparently it's a tool for turning unstructured data into structured data somehow, or something vaguely like that, so again, if you've read the book, that sort of makes sense.

I pulled back and canceled that moderator alert, because it seems this is actually a serious comment/question, and the poster was not spamming at all. What's next? A Babelfish translation filter?

Oh wait, that's been around for years.

Can you grok that?

    Well, first time I've heard "Kubernetes" I thought it was "uber-nazis", so there's that. :)

    These names just seem to be getting sillier and sillier if you ask me. I still don't understand how something called "Slack" ended up as an enterprise app. Kids these days...

      Scrum masters


      Black/white/green belts...

        Yeah, "scum/scam masters". Such wonderful phonetics. [eye roll] Who comes up with this stuff?

      • Aug 16, 2019 at 02:31 PM

        Oh, don't get me started! We're gonna sprint through the stories until all the epics achieve a theme, apparently.

      The whole tool chain has funny names: Jira, Confluence(don't confuse with Influenza), BitBucket, Bamboo(Big Bamboo Bar Munich?), JRebel(Che? Is it you?) and last but not least Splunk(like Thud! or Boink!). Where does 'Splunk' come from? From the MaxPlanck Institute?

      • Aug 14, 2019 at 01:58 PM

        There is a kids game called KerPlunk, not sure if it's some kind of homage to that. Or maybe just a random combination of letters. The humanity is running out of the meaningful names, it seems.

        "Spelunking" is the act of exploring caves. I wonder if it comes from that?

        Manfred Klein Actually, my the name of my niece is Jira so I like it :-)

        • Aug 15, 2019 at 09:56 AM

          Exactly. A nice girls name. But a name for a software? Imagine disruptive new software with names like Barbara, Jennifer or Susan.

          And the confusion. 'Oh no! My Patricia crashed again!'. 'Oh gosh, my Kate licence expired'. 'Hey! Who removed my Quendolin??'

        • Aug 16, 2019 at 02:35 PM

          Are your niece's parents software developers, by chance? ;)

      • Aug 16, 2019 at 02:34 PM

        Well, Confluence actually makes sense, as that is a word that means two (or more) things coming together to form a single whole. Usually it means when two big rivers merge to form a mighty river.

        Yesterday I learned we had purchased a new tool called Papercut. Everyone in the room winced in pain. It's purpose, apparently, is to prevent people from printing massive tomes and burning through paper, so I guess the name makes sense, but still it evokes a certain memory that almost everyone can identify with, and not a pleasant one.

        Oh, and BitBucket (as a word) dates at least as far back as my mainframe days in the early 80s. It was slang for deleting something, whether by accident or intentionally, and... hmm, I'm not sure anymore, but... I think it was the actual name of an operating system component within the CDC Cyber 170 NOS in those days. Hard to tell with googling now, because all that comes up is some modern piece of software.

          Bitbucket origin

          History. Originally, the bit bucket was the container on Teletype machines or IBM key punch machines into which chad from the paper tape punch or card punch was deposited; the formal name is "chad box" or (at IBM) "chip box". The term was then generalized into any place where useless bits go,

      Was reminded of this blog today after getting an email sent by "Taco from Trello". Gah! We are Fortune 500 company, people! :)

      Oh freddled gruntbuggly,
      Thy micturations are to me
      As plurdled gabbleblotchits on a lurgid bee.
      Groop, I implore thee, my foonting turlingdromes,
      And hooptiously drangle me with crinkly bindlewurdles,
      Or I will rend thee in the gobberwarts
      With my blurglecruncheon, see if I don't!

    And what about screwy spelling, to be down wid da cool kidz?

    My agency makes me use an online Timesheetz portal. A popular time tracking app is Toggl, although I personally use Tyme (which, despite it's name, is actually quite good). And then there are sites like tumblr, flickr, lyft. I'm surprised Twitter hasn't devoweled itself to Twitr.

      Just wait, SAP will become known as 'Sp?,We'll have s4hn.

      And for time tracking, fldglss

        Love it! Not to forget fuelling your programming with BP, and lnrd sounds so much more learned than Leonardo.

    • Sep 03, 2019 at 01:43 PM

      Could be worse, you could be using a T|/\/\e$337z portal (yes I did use wikipedia to come up with this ghastly concoction)
