Dropping permissions: running Ruby command as user ec2-user

If I try this without using sudo for rbspy, I get a different error message:

I have been fighting with rbspy for two weeks, using different operating systems on different machines. Nothing works; I just get info on bundle exec.

Time to figure something else out. It is just frustrating, because I know @parkr has been able to generate flamegraphs with rbspy in the past 🤷‍♂️

I used a version of ruby installed with rbenv. How are you installing your ruby? I had a number of problems with it, but was able to get it to work sometimes. :/

I know rbspy generates a nice flamegraph, but if its so much hassle, why don't we try generating flamegraphs using another program, like, Stackprof, ruby-prof-flamegraph, etc..?

[pathawks]

I’ve been exclusively using RVM. I will give rbenv a try and, if that doesn’t work, I will look into Stackprof.

[pathawks]

Using rbenv seems to fix the issue :+1:

[pathawks]

Note to self: Consider running pip install --upgrade pip on install

[pathawks]

Note to self:

echo 'eval "$(rbenv init -)"' > ~/.bash_profile
bundle config build.eventmachine --with-cxxflags="-O2 -pipe -march=native"

sudo chkconfig --add myscript 
sudo chkconfig --level 2345 myscript on

How long is a flamegraph or the report page going to be available before you archive it..?

[ashmaroli]

Technically, its an "Icicle Graph" instead of a "Flame Graph" :stuck_out_tongue:

Right now I am not planning to "archive" anything. Storage on S3 is cheap. If it gets to be a problem in the future we can reevaluate.

Yeah, rbspy changed the default output format and I haven't cared enough to worry about that yet. Internally, we've all been referring to "flamegraphs," so I have just kept that nomenclature.

[pathawks]

report is starting to get pretty hacky, but I'm choosing not to worry about that at this stage. Right now I'm just trying to get everything to work.

[pathawks]

It really bugs me that the body of the page does not seem to be center aligned with the header, but I cannot let that distract me 🙄

Once you're past the initial unstable dev stage, and are ready to use a layout that has CSS overrides for styles at jekyllrb.com, I can send a PR for that..

Let's focus on creating a Jekyll theme that we can use in multiple places (like the plugins directory).
