Presenter notes contain extra information which might be useful if you intend to use these slides for teaching.

Press `P` again to switch presenter notes off

Press `C` to create a new window where the same presentation will be displayed.
This window is linked to the main window. Changing slides on one will cause the
slide to change on the other.

Useful when presenting.

### <i class="far fa-question-circle" aria-hidden="true"></i><span class="visually-hidden">question</span> Questions

- What is gxadmin

- What can it do?

- How to write a query?

### <i class="fas fa-bullseye" aria-hidden="true"></i><span class="visually-hidden">objectives</span> Objectives

- Learn gxadmin basics

- See some queries and learn how they help debug production issues

---

# Database Queries

Sometimes it's the best way to get the exact data you need

Can be very useful for:
- Debugging
- Reporting
- Analytics

But consider: [`gxadmin`](https://github.com/usegalaxy-eu/gxadmin) and sharing your SQL

???

- Admins often need to run database queries.
- Debugging the live application in production is difficult, but running queries is easy.
- Additionally running SQL queries is commonly used for debuggin and reporting and analytics.
- The community collects queries we commonly use in a program called gxadmin.

---
# Database Queries

"Can you send me the number of jobs per day/state from Main in September and October?"

```sql
SELECT
  date_trunc('month', j.create_time) AS month,
  j.state,
  COUNT(j.state) AS job_count
FROM job j
LEFT OUTER JOIN galaxy_user u
  ON j.user_id = u.id
WHERE u.email != 'monitor@bx.psu.edu'
GROUP BY month,
         j.state
HAVING date_trunc('month', j.create_time) >= '2016-09-01'
AND date_trunc('month', j.create_time) < '2016-11-01'
ORDER BY month, j.state;
```

???

- We often get requests like how many jobs were run in a time period, and did they finish successfully.
- So we write some SQL like this.
- As an admin, you'll want to understand SQL.

---
# Database Queries

```console
        month        |  state  | job_count
---------------------+---------+-----------
 2016-09-01 00:00:00 | deleted |     11369
 2016-09-01 00:00:00 | error   |     15375
 2016-09-01 00:00:00 | new     |      1179
 2016-09-01 00:00:00 | ok      |    165963
 2016-09-01 00:00:00 | paused  |       933
 2016-09-01 00:00:00 | waiting |         9
 2016-10-01 00:00:00 | deleted |     13190
 2016-10-01 00:00:00 | error   |     12539
 2016-10-01 00:00:00 | new     |      1183
 2016-10-01 00:00:00 | ok      |    167547
 2016-10-01 00:00:00 | paused  |       645
 2016-10-01 00:00:00 | queued  |        75
 2016-10-01 00:00:00 | running |        36
 2016-10-01 00:00:00 | waiting |        17
(14 rows)
```

???

- Here is the output of such a query.
- SQL is very powerful for extracting data and graphs for reporting.

---
# gxadmin

- It's unpleasant to write queries every time you need them.
- So the community collects SQL in `gxadmin`.
- It's a giant bash script full of SQL and some magic ✨
- [github.com/usegalaxy-eu/gxadmin](https://github.com/usegalaxy-eu/gxadmin)

???

- We often re-run the same queries.
- gxadmin makes it easier by storing the useful queries.
- everyone is welcome to contribute to it.

---
# Database Queries

"I need a list of current main toolshed users and a number of their repos"

```console
$ gxadmin query ts-repos
```

**OR**

```sql
SELECT
  u.username,
  COUNT(r.id) AS r_count
FROM galaxy_user u
JOIN repository r
  ON u.id = r.user_id
WHERE NOT r.deleted
GROUP BY u.id
ORDER BY r_count DESC
LIMIT 12;
```

???

- However, some of these queries we run over and over.
- And those we include in gxadmin.
- This way every admin has access to all of the interesting queries we run.
- And we don't get repetitive strain injury typing SQL.

---
# Database Queries

???

- Example output from the previous query.

---

# Database Queries

"What is the status of this job"

*Lots* of SQL or: `gxadmin report job-info <job-id>`

```console
# Galaxy Job 5132146

Property      | Value
------------- | -----
         Tool | toolshed.g2.bx.psu.edu/repos/bgruening/canu/canu/1.7
        State | running
      Handler | handler_main_2
      Created | 2019-04-20 11:04:40.854975+02 (3 days 03:35:04.881599 ago)
Job Runner/ID | condor / 568537
        Owner | e08d6c893f5

## Destination Parameters

???

- Another extremely common query is: what is the status of this job?
- There is a gxadmin command which aggregates information about jobs.
- This can help you debug job failure to run issues.

---

# Database Queries

"Get me a list of recently registered users"

```console
$ gxadmin query latest-users
```

**OR**

```sql
SELECT
	id,
	create_time AT TIME ZONE 'UTC' as create_time,
	pg_size_pretty(disk_usage) as disk_usage,
	username,
	email,
	active
FROM galaxy_user
ORDER BY create_time desc
LIMIT 40
```

???

- Another common query, who has recently joined our server?
- This is an easy command to write, but it is also included in gxadmin.

---

# Database Queries

```console

id  |          create_time   | disk_usage |  username   |    email    |    groups    | active

```

???

- Example output of the previous query.
- With SQL you can choose just the columns or data that is relevant to you.
- This may not be so easily available in the interface.

---

# Tabular Output

Converting SQL query output to tabular and other formats

```SQL
COPY (...) to STDOUT with CSV DELIMITER E'\t'
```

**or**

```console
$ gxadmin query ...
$ gxadmin tsvquery ...
$ gxadmin csvquery ...
```

???

- However to reuse this data in other applications, the postgres format is not convenient.
- There is special syntax you can use to output CSV.
- gxadmin includes query variants to do this as well.

---

# Monitoring

Telegraf can consume Influx formatted output, which `gxadmin` can produce:

```console
$ gxadmin iquery queue
queue,tool_id=ncbi_blastx_wrapper/0.3.1,state=running count=76
queue,tool_id=rna_star/2.6.0b-2,state=queued count=36
queue,tool_id=rna_star/2.6.0b-2,state=running count=15
queue,tool_id=unicycler/0.4.7.0,state=running count=10
queue,tool_id=hisat2/2.1.0+galaxy4,state=running count=9
```

???

- For monitoring, many galaxy sites use Influx DB.
- gxadmin supports exporting influx compatible format.
- This makes it easy to add new data and graphs to your monitoring.

---
### <i class="fas fa-key" aria-hidden="true"></i><span class="visually-hidden">keypoints</span> Key points

- gxadmin is a tool to run common database queries useful for Galaxy admins

- new queries are welcome and easy to contribute
