The reports application gives some pre-configured analytics screens. These are very easy to setup and can help with debugging issues in Galaxy.

Setting up Reports
The reports application is included with the Galaxy codebase and this tutorial assumes you’ve already done all of the setup required for Galaxy, systemd, uWSGI, and NGINX.
Hands-on: Setup Reports
First we add a basic configuration of the Reports app to the playbook templates. Create
templates/galaxy/config/folder, if it doesn’t exist, and createtemplates/galaxy/config/reports.ymlwith the following contents:--- /dev/null +++ b/templates/galaxy/config/reports.yml @@ -0,0 +1,4 @@ +reports: + database_connection: "{{ galaxy_config.galaxy.database_connection }}" + file_path: "{{ galaxy_config.galaxy.file_path }}" + template_cache_path: "{{ galaxy_mutable_data_dir }}/compiled_templates/reports/"If you haven’t worked with diffs before, this can be something quite new or different.
If we have two files, let’s say a grocery list, in two files. We’ll call them ‘a’ and ‘b’.

There are a couple different formats to diffs, one is the ‘unified diff’

🥑This is basically what you see in the training materials which gives you a lot of context about the changes:
--- oldis the ‘old’ file in our view+++ newis the ‘new’ file- @@ these lines tell us where the change occurs and how many lines are added or removed.
- Lines starting with a - are removed from our ‘new’ file
- Lines with a + have been added.
So when you go to apply these diffs to your files in the training:
- Ignore the header
- Remove lines starting with - from your file
- Add lines starting with + to your file
The other lines (🍊/🍋 and 🥑) above just provide “context”, they help you know where a change belongs in a file, but should not be edited when you’re making the above change. Given the above diff, you would find a line with a 🍒, and replace it with a 🍍
Added & Removed Lines
Removals are very easy to spot, we just have removed lines

Comment: Insecure!But notice that your Reports server is not secured! Check out the External Authentication tutorial for information on securing Reports.
Hands-on: Time to git commitIt’s time to commit your work! Check the status with
git statusAdd your changed files with
git add ... # any files you see that are changedAnd then commit it!
git commit -m 'Finished Galaxy Monitoring with Reports'
Comment: Got lost along the way?If you missed any steps, you can compare against the reference files, or see what changed since the previous tutorial.
If you’re using
gitto track your progress, remember to add your changes and commit with a good commit message!
