I would like my watcher to run from Monday to Friday only. So I'm trying to use this schedule:
"trigger": {
"schedule" : { "cron" : "0 0 0/4 * * MON-FRI" }
},
"input": {
...
However, I'm getting
Error
Watcher: [parse_exception] could not parse [cron] schedule
when I'm trying to save the watcher. Removing MON-FRI does helps but I need it.
This expression works:
0 0 0/4 ? * MON-FRI
But I'm not sure I understand why ? is required for either the day_of_week or day_of_month
Thank you!
I believe this is what you are looking for:
"0 0 0/4 ? * MON-FRI"
You can use croneval to check your cron expressions 1:
$ /usr/share/elasticsearch/bin/x-pack/croneval "0 0 0/4 ? * MON-FRI"
Valid!
Now is [Mon, 20 Aug 2018 13:32:26]
Here are the next 10 times this cron expression will trigger:
1. Mon, 20 Aug 2018 09:00:00
2. Mon, 20 Aug 2018 13:00:00
3. Mon, 20 Aug 2018 17:00:00
4. Mon, 20 Aug 2018 21:00:00
5. Tue, 21 Aug 2018 01:00:00
6. Tue, 21 Aug 2018 05:00:00
7. Tue, 21 Aug 2018 09:00:00
8. Tue, 21 Aug 2018 13:00:00
9. Tue, 21 Aug 2018 17:00:00
10. Tue, 21 Aug 2018 21:00:00
For the first expression you'll get following java exception:
java.lang.IllegalArgumentException: support for specifying both a day-of-week AND a day-of-month parameter is not implemented.
You can also use Crontab guru to get human readable descriptions like:
At every minute past every 4th hour from 0 through 23 on every day-of-week from Monday through Friday.
The question mark means 'No Specific value'. From the documentation on Quartz's website:
? (“no specific value”) - useful when you need to specify something in one of the two fields in which the character is allowed, but not the other. For example, if I want my trigger to fire on a particular day of the month (say, the 10th), but don’t care what day of the week that happens to be, I would put “10” in the day-of-month field, and “?” in the day-of-week field. See the examples below for clarification.
http://www.quartz-scheduler.org/documentation/quartz-2.x/tutorials/crontrigger.html
I suppose since you want your schedule to run every 4 hours, mon-fri, the actual day of the month is irrelevant, so the ? specifies that. * on teh other hand would be 'all values' which would not make sense since you are specifying only mon-fri for day of the week.
Hope that helps!

my data looks like
JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC
22.60 24.60 30.60 34.60 36.20 35.70 32.10 30.20 31.40 31.60 28.00 24.80
25.40 27.60 32.40 34.60 36.50 38.10 31.70 31.40 30.30 30.20 27.00 23.90
and there are like hundreds of rows! I want to find a maximum value in each row and write it in different column next to data along with month
so my out put will be
36.20 MAY
38.10 JUN
.
.
I want to use maxloc function, but i have no idea how to use it!
Try
index = maxloc(myTable(3,:))
print *, myTable((/1,3/), index)
It should select the highest value from the third row and display the first and third value at this index.
I create a hash with months as keys and timelaps as values
biens_delai[bien_date.mon] = b.delai
I get this result without month parsing
{Wed, 18 Jan 2017=>3.0, Sat, 25 Feb 2017=>2.0, Fri, 17 Mar 2017=>3.0, Sat, 25 Mar 2017=>5.0, Tue, 18 Apr 2017=>2.0, Thu, 29 Jun 2017=>2.0}
In March i have 2 values but when i parse by month i get the most high value and i want a addition of 2 values for March not the most high
{1=>3.0, 2=>2.0, 3=>5.0, 4=>2.0, 6=>2.0}
That's not the high value which you are getting, the values are getting overwritten, try the following
biens_delai[bien_date.mon] = biens_delai[bien_date.mon].to_f + b.delai
I have a collection, that I would like to achieve group by the year and month.
2014
jan
2nd
5th
...
feb
11th
12th
...
mar
...
2013
jan
feb
mar
...
2012
jan
feb
mar
...
this is my current collection but only by year. I couldn't get what I really wanted with this.
$collection =$model->orderBy('date', 'desc')->get()->groupBy(function($item) {
return $item->date->format('Y');
});
Do a Group By on DB::raw('MONTH(your date variable)')
For example, try this:
$model->orderBy('date')->groupBy(DB::raw('MONTH(date)'))->selectRaw('DATE_FORMAT(date, "%M %Y") as Month)->get();
I am creating a range for each month in my example range.
example_range = (Time.zone.today..2.years.from_now)
Output should look like so:
=> [Wed, 03 Aug 2016..Wed, 31 Aug 2016, Thu, 01 Sep 2016..Fri,
30 Sep 2016, Sat, 01 Oct 2016..Mon, 03 Oct 2016, ...]
At the moment I'm doing this, which doesn't work for ranges longer than a year, because the grouping will put January '16 and January '17 in one group.
example_range.group_by(&:month).each { |_, month| month.first..month.last }
I also tried this, but ruby segfaults on this for some reason...
example_range.group_by(&:year).map{ |ary| ary.group_by(&:month)}
Does anyone know a more beautiful (or at least working) way of doing this?
How is this:
example_range.group_by {|date| [date.year, date.month] }.map {|_, month| month.first..month.last }
If you are using Active Support (Rails), this will also work:
example_range.group_by(&:beginning_of_month).map {|_, month| month.first..month.last }
The best solution I think is this:
example_range.group_by {|date| date.month.to_s + "-" + date.year.to_s}
You can adjust the way you need.
I want to run some cronjob between monday-friday at 23.50 and 23.55. I tried some expressions but there is something wrong with my expression.
0 50/5 23-00 ? * MON-FRI
When I calculate next days with cronmaker it shows;
1. Tuesday, March 15, 2016 11:50 PM
2. Tuesday, March 15, 2016 11:55 PM
3. Wednesday, March 16, 2016 12:50 AM
4. Wednesday, March 16, 2016 12:55 AM
5. Wednesday, March 16, 2016 11:50 PM
Why it shows AM? I only specified 23-00 hours?
It should be 0 50/5 23 ? * MON-FRI
'-' specifies range. So, 0 50/5 23-00 ? * MON-FRI means 11pm to 12am
12:50 AM is the same as 00:50 or 24:50. 50 minutes after midnight. Since the hour is 00 and the minute 50 it matches your cron expression.
0 50/5 23-00 ? * MON-FRI
it can be write as below may fullfill your requirement
0 50/5 23 * * 1-5 ?
explain 1-5 means 1 = monday
... 5 = Friday
note: sunday = 0 or 7
