i´ve a quick question regarding a zabbix trigger expression. Our script finds out the certification lifetime while returning a number into a file. I already created some triggers for specific time spans (like 10 days or 44 days).
For example:
{Certificate Lifetime:vfs.file.contents[C:\Zabbix_scripts\cert.txt].prev()}<=30 and {Certificate Lifetime:vfs.file.contents[C:\Zabbix_scripts\cert.txt].prev()}>10
I now want to have a trigger which will cause an "Disaster" when the value in the .txt file is unavailable, like the txt file is empty.
I´ve tried
{Certificate Lifetime:vfs.file.contents[C:\Zabbix_scripts\cert.txt].prev()}=0
But this was not the right sulution. Any ideas?
Moreover we have some machines which are equal to others but doesn´t show any value. Any ideas at this point?
Regards
You should be able to detect empty item value with something like this:
strlen()=0

Currently, I was working on a Unity project and using Firestone as my database.
now i facing a problem is when i create a document in firestone i want to add the time of creation also.
i was using the code
db.Collection("Challenges").Document(addedDocRef.Id).UpdateAsync("TimeCreated", Firebase.Firestore.FieldValue.ServerTimestamp);
but it always update the same time in firestone.
every document get same timestemp, can anyone teach me how to solve this issue?
The FieldValue properties are sentinel values in this case to be understood as dummy values that are supposed to be filled in by "someone".
I don't know how Firebase works exactly and who is supposed to fill this in but what you get basically equals DateTime.UnixEpoch the default uninitialized system time (+ 7:30 timeszone shift). It might have to be configured accordingly somewhere before it works correctly.
You could instead simply pass in your own timestamp using e.g. DateTime.Now
VB6 will REPORT a LEFT location greater than max integer when the form is in an auxiliary screen. However, I cannot assign that value as a LEFT specification.
I manually drag frmSecondary to the secondary monitor (located to the right of my primary monitor).
I click a button within frmSecondary in order to write the value of frmSeconday.Left to a file. It writes 49950.
I close the program, then re-open.
I read the value from the file (and the value IS 49950).
I try to programmatically assign that value to frmSecondary.Left
Failure (works OK if the value is less than "largest integer").
Expected result: I should be able to assign the value that was written to file. Better yet, any ideas of how to programmatically place frmSecondary at it's "proper" location on the secondary monitor?
I simply read the value from file:
Input #fnum, frmSecondary.left
I've tried, without success:
Dim lft as variant
Input #fnum, lft
frmSecondary.left = lft
I have confirmed that the value being read from file is, in fact, 49950. I do this confirmation two ways...one is by looking at the file; the second is by putting a "stop" in the program and showing the value of lft.
TOTAL NONSENSE
Ignore this entire post. I just discovered my error -- it's so embarrassing, I don't even want to describe it. Nothing quite like spending an entire afternoon (to say nothing of YOUR time) chasing garbage.
I still have this problem
Exception in component tOracleOutput_1

There is some currupt code in your job. What you can do is first check is there any code generated for this job. if not try removing each component/disable and run and see if the error persist or not
I have had this as well. What usually helps is restarting Talend or restarting the computer.
If that doesn't help, there is something wrong with the job. Then I check every schema, every connection, every tMap, every item in the job if there is an error which Talend doesn't show to me.
To check if the code generation system works, you can always click on the Code tab and see if something comes up.
EDIT
An error ORA-00904 comes up. This leads to the suggestion that a column is named wrongly as seen here: https://dba.stackexchange.com/questions/129641/ora-00904-error-while-querying-the-oracle-database-table
To avoid ORA-00904, column names must
begin with a letter.
consist only of alphanumeric and the special characters ($_#); other characters need double quotation marks around them.
be less than or equal to thirty characters.
I am currently using SQL Server 2008R2.
I am using this script:
SELECT a.productname, a.orderdate, a.workarea
FROM database1table1 AS a
WHERE a.orderdate >='2016/08/01'
Which gives the output:
PRODUCT NAME ORDER DATE WORKAREA
x 2016/08/07 NULL
y 2016/08/09 HOLDING
z 2016/08/10 ACTION
a 2016/08/12 ACTION
My problem arises when I amend the above script to read,
...
WHERE a.orderdate >='2016/08/01'
**AND a.workarea NOT IN ('HOLDING')**
When I do this, not only does it remove 'HOLDING', but it also removes the NULL rows as well, which I definitely do not want.
Please can you suggest an amendment to the script to prevent the NULLS being removed - I only want to see the value 'HOLDING' taken out.
With many thanks!
You can try a workaround
AND ISNULL(a.workarea,'') NOT IN ('HOLDING')
It will transform all null a.workarea in the "where" the "not in" works correctly
When fields are nested, there is a problem.
foreach (Word.Field field in this.Application.ActiveDocument.Fields)
{
field.Update();
text = field.Result.Text;
}
The above code does not work.
The process starts, but winds up in an endless loop or some other process that hangs the system.
Thinking about it, I can surmise that when you update a field, it might have an effect on the fields collection - thus, the loop fails.
Does anyone have any ideas on implementing this?
P.S. I know there is a Document.UpdateFields() method to update ALL fields. However, there are reasons why I cannot use this and need to only update specific field types.
My apologies! I was going to give an example of a nested field but was trying to test some more before sending anyone (Jack) on a goose-chase.
I waited and waited and waited, and after a good 2 or 3 minutes, it finished. After the last field, it crashed with this message:
Object has been deleted.
The error was generated from the following line inside the loop:
string text = field.Code.Text;
The template is being tested on mergefields that are not being found because I am testing without database connectivity. It would be odd, but explainable, that it goes through all the fields and then, at the end of the day, the very OUTER IF field's result is "Error! Reference source not found." But I still don't get why this could happen.
Nor do I understand why looping takes 3 minutes while a call to document.Fields.Update() will do the same thing in about 1 second and NOT result in the error described above.
Again, my apologies. I never considered updating inside a loop would be vastly slower that a call to doc.fields.update().
