Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

osquery-extension

#Overview This software module enables one to add table plugins to OSQuery. The data for the new tables could come from many sources, for example:

  1. Data could come from invoking operating system API calls
  2. Data could come from making a REST API call to an external server
  3. The data could come from a log file

You could perform joins between OSQuery base tables and the extension tables to obtain unique insights into your infrastructure.

The extension + table plugin concept can quickly enable the integration of data which is not yet available as a part of base OSQuery. If you could write a REST service on a Windows server then the Windows OS related infromaion can be quickly made availabe under an OSQuery prompt.

#Prerequisites OSQuery must be installed on the computer you are running this sogtware. OSQuery should be run as the same user the user which runs the commands shown here.

#How to

Open two terminal windows

On terminal - 1 run the following commands

git clone https://github.com/umareddy/osquery-extension.git
cd osquery-extension
npm install

On terminal 2 type the following commands

osqueryi
select * from osquery_extensions;

Note the value in the path column (for the row where name = 'core'), this is the UNIX Domain socket to use to communicate with this osqueryi instance.

On terminal 1 type the following command

node extension.js <cut and paste the socket path here>

On terminal 1 run the following commands

.tables
select * from test_table_001;
select * from HERO_FOUNDERS;

You should see the two new tables that are part of OSQuery.

You can edit the the file extensions.js to add additional tables.

This example shows how one could write a process to programatically run sql commands and retrieve responses in JSON format. You could use this approach to provide a REST interface to OSQuery tables.

Open another terminal window and type the follwoing commands:

node query.js <cut and paste the socket path here>
select * from processes;
