If you look at review page for any of our Neutron commits, e.g.:
You'll see that there is a handy summary of CI results (with links to logs) in the upper right. However, there are some CIs which are missing from this summary, although we know that they had left a review comment or voted +1/-1 because they're listed in the Reviewer list on the left.
Note that there is an indirect way to find the logs for these CIs, by clicking on at the very bottom and scrolling through the results.
Henry Gessau checked with the openstack-infra team for clarification, and the explanation he got was that the Gerrit review page will only be able to include summaries for the CIs which leave review comments in the same format that the community Jenkins CI uses.
Here's an example of the Jenkins format (for illustration, hyperlinks and tabs are lost here in text mode):

For CIs which use a Zuul front end, this format comes automatic. But for others, the format of review comments may need some changes in order to match the Jenkins review comment format.
I don't think this is critical, but it would be nice to have everything summarized consistently.
