Retrospective analysis of a large dataset – screencast

I uploaded a new 5-min  screencast titled  “Retrospective analysis of network traffic with Trisul”.  This is an introductory screencast covering the following topics.

  1. Logging in and selecting a context
  2. Quick view of Live vs Retro dashboards
  3. Retro analysis page structure
  4. Expanding time window, zooming, and selecting timespan
  5. Network FAQ demo
  6. Using a retro tool demo
  7. Drilldown to flows and packets demo

Screencast of Trisul monthly alert calendar

Screenr rocks !

I just put together a screencast explaining the new monthly alert calendar feature. In case anyone had a doubt if I was a developer-geek or a suit, this ought to clear it up.


A note about screenr :

I had almost convinced myself that the wallet needed to be opened to buy a copy of Camtasia. I found screenr but was intimidated by two gotchas.

  • You had to record at one shot – not easy to edit or splice
  • No callouts or other tools available

Upon checking out lots of screenr videos, I changed my mind (closed the wallet). I actually like the rough and authentic look and feel of a screenr compared to the edited and polished output of a Camtasia.

I had to do a dozen redo’s of the above screencast, but now I have the hang of it. If you make an error correct it and keep going.

Embedding in WordPress :

If your screenr fails to embed in wordpress –

  1. Login as admin
  2. Go to Settings -> Media
  3. Ensure that the maximum width and height in the Embed section are set (mine is 600×500)

Enjoy !

New monthly alert calendar in Trisul

We have had a good number of people download Trisul in the past few days.

In the meantime, we pushed out a new feature called the Alert Calendar. Please get the new builds now to update.

Trisul alerts
Groups alert activity by priority by day

Since, Trisul is a metering platform – you can generate this calendar for any counter.

Some applications :

  • Traffic by IN/OUT per host per day
  • Malware alerts per day (using the Trisul Badfellas plugin)

In the screenshot above, Trisul will show you alerts grouped by Priority. You can click on the totals and get a further breakup grouped by type.

Reminder to self : Get some screencasts out now !
