Skullerz first looks

I recently was able to get a pair of Skullerz Loki glasses from toweroneinc. You can pick up your own pair at https://toweroneinc.com/collections/clothing/products/skullerz-loki-safety-glasses-goggles

So why are these cool? First of all they are a google style. A good friend of mine Michael Pelsor figures out a few years ago if you keep your eyeballs warm in the winter your whole body thinks it’s warmer than it really is. These glasses fit around your eyes like a ski google, without the bulk.

Secondly, these glasses have a headband you can swap out the temple pieces with a stretchable headband so they stay on your head.

Fear in IT

I have always been a firm believer in re-evaluating yourself on a regular basis. Take a look at yourself, your behaviors, and your quirks. By doing this, you can uncover weaknesses you. Read to work on, but also build on your strengths.

Case in point. I am in the process of rolling out wiki software for many clients. This software deployment will be a cookie cutter rollout, with customizations for each client after the initial implementation. I am behind on this for one big reason. Fear. Now, this is not Michael Meyers standing over your bed fear. It’s a fear of choosing the wrong platform. I have evaluated several wiki packages and talked to several people deploying each of them. Like most things, they have strengths and weaknesses. The fear breeds indecision. Is there something out there which I haven’t found that is better? Is there a better way or a way I haven’t thought of to accomplish what I am trying? The answer to all of these is probably yes.

How do you not fall into the trap of indecision? Couple of things you can do.

1. Before anything like this sit-down and write out the problem you are trying to solve. In my case with the wikis, I needed something to keep track of not only documentation but the odds and ends notes.

2. Write down what would help solve the issue. In my case an online repository of information.

3. Create a list of ways to solve this problem. This step may involve research. What are the software packages out there to address my issue? Are we utilizing anything today which could resolve this issue?

3. Once you have done some research formulate the must needed features in your solution.  From there prioritize them.

4. Many people start to break down during this stage.  Whether it is getting overwhelmed from the sheer amount of choices or thinking every feature is needed.  The decision process begins to grind to a halt rather quickly. How do you overcome this? First, be realistic, how many of the features do you really need to accomplish your goal? Out of the features left, what does it take to implement them? How many times have you deployed a software tool and are only utilizing a fraction of the tools available? This happens quite a bit.

5.Set a hard time to make a decision.  Tell yourself you have ten business days to research and come up with the solution.  Once you have made the decision, have a rollout plan in place.  This plan should include a timeline of start and finish.  This way you don’t start to second guess yourself and drag your feet even more.

This method is not a foolproof way, but it will get you to implement more things than you are now.

BGP Monitoring RFC 7854

https://tools.ietf.org/html/rfc7854

   This document defines the BGP Monitoring Protocol (BMP), which can be
   used to monitor BGP sessions.  BMP is intended to provide a
   convenient interface for obtaining route views.  Prior to the
   introduction of BMP, screen scraping was the most commonly used
   approach to obtaining such views.  The design goals are to keep BMP
   simple, useful, easily implemented, and minimally service affecting.
   BMP is not suitable for use as a routing protocol.

The importance of Network Monitoring Systems (NMS)

One of our open tickets on MidWest-IX is a member reporting slow speeds on their exchange port. After having them send us some data and a few e-mails back and forth we began looking at their switch port on the fabric.  Right away we noticed errors on the port. After a counter reset the errors were still incrementing

 19 runts  0 giants  1210 CRC  0 no buffer
 1329 input error  0 short frame  0 overrun  0 underrun  0 ignored

This led us to look at our LibreNMS data for this port.  A quick look shows on October 31st the port started seeing input errors.

By dilling down we are able to see exactly when this started happening

We now have responded to the customer to see if anything changed that day. Maybe a new switch, new optic, or software upgrade.  By having this data available in an NMS we were able to cut down on troubleshooting by a huge margin.  We now know when the issue started and are closer to the root cause of this.  Without this data, we would be spending more time trying to diagnose and track down issues.
