Please find my observations,

1. Nginx naming

The Nginx docs page has the naming convention as NGINX. Our integration docs page represents with the naming convention as Nginx. This makes different representation's in the docs page. see below,

From Integration page:

From the docs page:

• Can we make the naming of Nginx consistent in both the places. I would suggest to update the docs to replace NGINX with Nginx.

2. Alignment

• Please fix the alignment issues in the logs to make it similar to metrics.

3. Suggestions on Add Agent section

• When looking at the Fleet enrolment section. I was noticing different representations in other pages. Can we consolidate the Add Agent as a separate section and reference from the documentation page here. This would also help keeping the length of the documentation short.

Looks good. Just a few thoughts.

NGINX mostly stylizes their name in all caps, but they have trademarked both NGINX and nginx. We should really be using one of those in our integration, but I've now switched instances of NGINX to nginx except when referencing a feature or section of the integration. There I've used Nginx.

2. Alignment

• Please fix the alignment issues in the logs to make it similar to metrics.

Unfortunately, I think this is a bug in our styles due to the horizontal list having more than one line.

3. Suggestions on Add Agent section

Thanks for pointing this out. I think there may be a case for some reuse between these docs. There are some slight differences (mostly in the K8s integration) that may make things a little unclear for users. For now, I would like to keep these instructions here to keep users in the flow, but maintaining all of these separately may become too big of a task so I will look into reuse here and updating the necessary pages.
