I am using Grafana v8.3.5 + Postgres.
And using the Time Series line chart where I want to display the value the query is returning, but would like that the tooltip shows me other information.
select timestamp as "time", value, build, version, from size;
timestamp | build | version | value
----------------------------+-------+-----------+-------
2022-04-24 06:50:10.933324 | 1.11 | 0.1_alpha | 265
2022-04-24 06:50:45.15727 | 2.11 | 0.1_alpha | 280
2022-04-24 06:50:52.535592 | 3.11 | 0.1_alpha | 273
2022-04-24 06:52:12.885316 | 4.11 | 0.1_alpha | 224
...
Is it possible at all that the tooltip shows all this extra information (containing strings) besides the actual value?
I tried to add a new query formatted as table, but it doesn't show up as a new series...

I'm wanting to create a graph panel in Grafana which shows the top 10 highest consumers of CPU and show their respective history over whatever time interval has been selected. I think that last part is the tricky bit.
I have this so far:
SELECT TOP("median_Percent_Processor_Time", 10) as "usage", host FROM (
SELECT median("Percent_Processor_Time") AS "median_Percent_Processor_Time" FROM "telegraf_monitoring"."autogen"."win_cpu" WHERE time > now() - 5s GROUP BY time(:interval:), "host" FILL(none)
)
This produces the following table:
time | usage | host
12/17/18 02:38:36PM | 88.4503173828125 | CNVDWSO202
12/17/18 02:38:36PM | 60.55384826660156 | CNVDSerr01
12/17/18 02:38:36PM | 46.807456970214844 | NVsABAr01
12/17/18 02:38:36PM | 27.402353286743164 | NVDARCH02
12/17/18 02:38:36PM | 21.320478439331055 | NVDABAr05
12/17/18 02:38:36PM | 5.546620845794678 | NVDALMBOE
12/17/18 02:38:36PM | 3.654918909072876 | NVDLeNCXE01
12/17/18 02:38:36PM | 47.08285903930664 | NVDOKTARAD01
The table is useful but thats just a single point in time. I need to subsequently query and pull time series data from that win_cpu measurement for those 10 hosts. The hosts values are dynamic, I have no way of predicting what will show up and because of that I cant string together OR statements and Influx doesnt support IN as far as I can see.
You can use OR regexp instead of IN. =~ /HOST1|HOST2|HOST3/ + GROUP BY host and one InfluxDB query will return all data. The tricky part is Grafana variable, which will have those top 10 hosts. When you have it, then just use advance variable formatting in the regexp query - for example =~ /${tophosts:pipe}/.
I have strings that look like this:
schedulestart | event_labels
2018-04-04 | 9=TTR&11=DNV&14=SWW&26=DNV&2=QQQ&43=FTW
When I look at it in the database. I have code that relies in this string in this format to display a schedule with events with those labels on those days.
Now I find myself needing to break down the string in postgres for reporting/analysis, and I can't really pull out the string and parse it in another language, so I have to stick to postgres.
I've figured out a way to unpack the string so my results look like this:
User ID | Schedule Start | Unpacked String
2 | 2018-04-04 | TTR
2 | 2018-04-04 | 9
2 | 2018-04-04 | DNV
2 | 2018-04-04 | 11
2 | 2018-04-04 | SWW
2 | 2018-04-04 | 14
2 | 2018-04-04 | DNV
2 | 2018-04-04 | 26
select schedulestart, unnest(string_to_array(unnest(string_to_array(event_labels, '&')), '=')) from table;
Now what I need is a way to actually perform an interval calculation (so 2018-04-04+11 days::interval), and I can if I only get a numbers list, but I need to also bind that result to each string. So the goal is an output like this:
eventdate | event_label
2018-04-12 | TTR
2018-04-20 | DNV
Where eventdate is the schedule start + which day of the schedule the event is on. I'm not sure how to take the unpacked string I created and use it to perform date calculations, and tie it to the string.
I've considered doing only one unnest, so that it's 11=TTR and 14=DNV, but I'm not sure how to take that to my desired result either. Is there a way to read a string until you reach a certain character, and then use that in calculations, and then read every character past a certain character in a string into a new column?
I'm aware completely rewriting how this is handled would be ideal, but I did not initially write it, and I don't have the time or means to rewrite the ~20 locations this is used.
Here is your table (I added userid column):
CREATE TABLE test(userid INTEGER, schedulestart DATE, event_labels VARCHAR);
And input data:
INSERT INTO test(userid,schedulestart , event_labels) VALUES
(2,DATE '2018-04-04', '9=TTR&11=DNV&14=SWW&26=DNV&2=QQQ&43=FTW');
And finally the solution:
SELECT
userid,
(schedulestart + (SPLIT_PART(kv,'=',1)||' days')::INTERVAL)::DATE AS eventdate,
SPLIT_PART(kv,'=',2) AS event_label
FROM (
SELECT
userid,schedulestart,
REGEXP_SPLIT_TO_TABLE(event_labels, '&') AS kv
FROM test
WHERE userid = 2
) a
How would you create a trigger that uses the values of the row being inserted to be calculated first so that a value being inserted gets transformed?
Let's say I have this table labor_rates,
+---------------+-----------------+--------------+------------+
| labor_rate_id | rate_per_minute | unit_minutes | created_at |
+---------------+-----------------+--------------+------------+
| bigint | numeric | numeric | timestamp |
+---------------+-----------------+--------------+------------+
Each time a new record is created, I need that the rate is calculated as rate/unit (the smallest unit here is a minute).
So example, when inserting a new record:
INSERT INTO labor_rates(rate, unit)
VALUES (60, 480);
It would create a new record with these values:
+---------------+-----------------+--------------+----------------------------+
| labor_rate_id | rate_per_minute | unit_minutes | created_at |
+---------------+-----------------+--------------+----------------------------+
| 1000000 | 1.1979 | 60 | 2017-03-16 01:59:47.208111 |
+---------------+-----------------+--------------+----------------------------+
One could argue that this should be left as a calculated field instead of storing the calculated value. But in this case, it would be best if the calculated value is stored.
I am fairly new to triggers so any help would be much appreciated.
Given a table that has a column of time ranges e.g.:
| <2015-10-02>--<2015-10-24> |
| <2015-10-05>--<2015-10-20> |
....
how can I create a column showing the results of org-evalute-time-range?
If I attempt something like:
#+TBLFM: $2='(org-evaluate-time-range $1)
the 2nd column is populated with
Time difference inserted
in every row.
It would also be nice to generate the same result from two different columns with, say, start date and end date instead of creating one column of time ranges out of those two.
If you have your date range split into 2 columns, a simple subtraction works and returns number of days:
| <2015-10-05> | <2015-10-20> | 15 |
| <2013-10-02 08:30> | <2015-10-24> | 751.64583 |
#+TBLFM: $3=$2-$1
Using org-evaluate-time-range is also possible, and you get a nice formatted output:
| <2015-10-02>--<2015-10-24> | 22 days |
| <2015-10-05>--<2015-10-20> | 15 days |
| <2015-10-22 Thu 21:08>--<2015-08-01> | 82 days 21 hours 8 minutes |
#+TBLFM: $2='(org-evaluate-time-range)
Note that the only optional argument that org-evaluate-time-range accepts is a flag to indicate insertion of the result in the current buffer, which you don't want.
Now, how does this function (without arguments) get the correct time range when evaluated is a complete mystery to me; pure magic(!)
Here is my table in the database :
id | account_name | account_number | account_type | address | email | ifsc_code | is_default_account | phone_num | User
-----+--------------+----------------+--------------+---------+------------------------------+-----------+--------------------+-------------+----------
201 | helloi32irn | 55265766432454 | Savings | | mypal.appa99721989#gmail.com | 5545 | f | 98654567876 | abc
195 | hello | 55265766435523 | Savings | | mypal.1989#gmail.com | 5545 | t | 98654567876 | axyz
203 | what | 01010101010101 | Current | | guillaume#sample.com | 6123 | f | 09099990 | abc
On form submission in the view, which only posts a single parameter which in my case is name= "activate" which corresponds to the column "is_default_account" in the table.
I want to change the value of "is_default_account" from "t" to "f". For example here in the table, for account_name "hello" it is "t". And i want to deactivate it, i.e make it "f" and activate any of the other that has been sent trough the form
This will update your table and make account 'what' default (assuming that is_default_account is BOOLEAN field):
UPDATE table
SET is_default_account = (account_name = 'what')
You may want limit updates if table is more than just few rows you listed, like this:
UPDATE table
SET is_default_account = (account_name = 'what')
WHERE is_default_account != (account_name = 'what')
AND <limit updates by some other criteria like user name>
I think to accomplish what you want to do you should send at least two values from the form. One for the id of the account you want to update and the other for the action (activate here). You can also just send the id and have it toggle. There are many ways to do this but I can't figure out exactly what you are trying to do and whether you want SQL or Playframework code. Without limiting your update in somewhere (like id) you can't precisely control what specific rows get updated. Please clarify your question and add some more code if you want help on the playframework side, which I would think you do.
