I want to generate alert when payload information provided in request size is greater than specified limit I Use like below but alert is generating continously . but I want to generate only when there is higher value .I am using histogram metric
application_pkg_size{quantile="0.99"}/1000 > 5000
above alert generates alert continously . even when requests are not fired

we bought a Printronix RFID printer T4304 with these dates:
FirmwareP301189 V1.21A
Serial NumberT4K431948007
Our wish is
to produce RFID-Labels with an QR-Code which includes the EPC-number
of the label. The QR-Code shall look like this:
http://qr.mycompany.com/epc/E280689123456789012345
We were hoping to use it with the Software Nicelabel. But Nicelabel
is only able to produce a QR-Code with only the EPC-Number but not
with our http://qr.my..../epc/ in front.
I had the idea to save the printjob as file. So I was able to
manipulate the file and send that file as printjob to the Printronix
printer like this:
lpr -S 192.168.1.2 -P raw myprintjob.prn
I found the document PTX_PRM_PGL_P7_253642C.pdf
which describes how the printer language is working. But I cannot
fulfill my destination.
My myprintjob.prn looks like this:
!PTX_SETUP
ENGINE-IMAGE_SHFT_H;0
ENGINE-IMAGE_SHFT_V;0
ENGINE-WIDTH;04146.

The result is a QRcode which only includes the first part of the string:
"http://qr.mycompany.com/epc/"
but not the "EPCCODE". I am looking for a hint how to do this.
Maybe I could find out the EPC-code via REST or telnet or so and create a special printjob for every single label?
Thanks for your help,

Printronix T4000, talk with port 9100 to get info from the printer
Author
Richard Lippmann, Stadt Zirndorf, EDV
Documentinformation
name: talk-with-port9100-to-get-infos-from-printronix-rfid-printer.md
revision: 2021-12-02 - init
What I want to achieve
I want to know the RFID-code from the label which is under the print-head.
With this information I am able to build a printjob with Qrcode which includes
the RFID-EPC.
I was not able to find out how to create a print-job with a qr-code.
I do not want this information in qrcode: ABC1234...567
But I want this information in qrcode: http://qr.mydomain.com/rfid/epc/ABC1234...567
With that I am able to take a picture of the label and go to a web-application
which helps me further with the device the label is on.
Documenation, where to find information
The printer language is described in the document which is easy to google: PTX_PRM_PGL_P7_253642C.pdf
My environment
Printronix T4000 printer with RFID-unit to read the RFID from the current label.
How to get info back from my printer
Usually Port 9100 is used to send a printjob to the Printronix-printer. Send job,
don't receive data. But you can switch the printer to be verbose, to send you
back information over the 9100-connection.
Glossary
EPC = this is the unique number which is in every RFID-label, just like
a MAC-address in a network card
PGL = the printer language. We can send printjobs with it, but also get information
from the printer about Configuration etc.
Human connect to the printer via Linux commandline
ssh me#shell.mydomain.com
export MYPRINTER=192.168.100.3
nc -v $MYPRINTER 9100
Put verbose mode on
The printer usually only receives information, but does not talk back.
You have to switch on the back-communication.
~CONFIG
SNOOP;STATUS
END
Put verbose mode off
I you are programming this interface with a programming
language like python, perl, ... it's a good idea to switch
verbose mode off after you did your job.
~CONFIG
SNOOP;OFF
END
IDENTITY
To see information:
put verbose mode on
send ~IDENTITY command
put verbose mode off
~CONFIG
SNOOP;STATUS
END
~IDENTITY
The result is:
T43040,V1.21A,12,131072KB
STATUS
To see information:
put verbose mode on
send ~IDENTITY command
put verbose mode off

Read one RFID-EPC-code from current label
These are things mentioned in this command:
~CREATE - start creating a new "form" (or subroutine to execute later)
VERIFY - the name of the subroutine we are creating. Keep it simple,
less than 15 characters, no special signs (see docu PTX_PRM_PGL_P7_253642C
page 60 under "CREATE" and page 29 under "Form Name" for exact informations)
NOMOTION - don't move the label to the next one after executing this job
DF511 = This is a variable-name, there seem to be a lot of variables in the printer
which are called by their numbers: DF1, DF2, ... I don't know which one I am
allowed to use, DF511 seems to work
96 = the RFID-EPC on my labels are 96 Bits long
H = Hexnumbers, the code is 96 Bit long, but I would like to see it like this:
ABC1234...567
VERIFY - a command to send information to the commandline.
~EXECUTE;VERIFY;1 - execute the form 1 time

Currently seeking assistance with the code on this site https://learn.microsoft.com/en-us/azure/iot-central/core/howto-create-custom-rules. Upon using the stream analytics job that uses a query to detect a disconnected deviceId, it returns null. Please see as follows:[all deviceId's for the disconnected device return a null, but timestamp is there.][1]
This is the query I used.

Since the Stream Analytics query uses the telemetry from the event hub as its input, can you please let me know if you followed the complete tutorial for the setup? In case yes, do you see the function log messages with the device id?
Also, do you receive the email from SendGrid with the deviceid? In order to analyze further, can you please also confirm that your stream analytics job is receiving inputs from the event hub?
I am working with capturing click stream variable on click. For example i want to capture value like size,color, amount once user adds any item to cart.
For this I m using
jQuery("body").append(jQuery('<* img src="https://******/clickstream?text='+JSON.stringify(text)+'" />'));
Here text is a JSON Object with variable captured from clicks like size, color and it invokes a REST API to push the data. However I am getting 400 Bad Request for this.
This works fine in case of
jQuery("body").append(jQuery('<*im g src="https://*****/clickstream?text='+"Some Hard coded stuff"+'" />'));
But fails for JSON.stringify(JSON Object) , gives 400
I have a REST API in JAVA , GET : /clickstream?text=text to capture the variable from clickstream
Can anyone please suggest what i m missing
Thanks in Advance
I am new to zabbix. I have a basic requirement of monitoring occurrence of different log messages using zabbix. Say, when there is a log message "server starting", zabbix should show that alert. The idea is that if the server (re)starts 10 times in last 10 minutes, the zabbix dashboard (or at any other place) should display that 10 times.
I have done the following for that :
Created an item under template MyTemplate:
Type : Zabbix Agent (Active)
key : log[/opt/mylog/logs/abc.log,server starting]
Type of information : Log
Update Interval (in sec) : 30
Created a trigger with expression :
{MyTemplate:log[/opt/mylog/logs/abc.log,server
starting].logeventid(1)}=0
With logeventid(1), I am seeing that the alert (trigger) is getting generated only once. It appears only once in the Dashboard --> Last 20 issues. If I go to Monitoring --> Trigger, I see the alert only once, although the log files have 10 entries of the message "server starting" (server restarted 10 times).
Then I set the trigger to following :
{MyTemplate:log[/opt/mylog/logs/abc.log,server
starting].nodata(300)}=0
Now, at Monitoring --> Trigger, I see the alert (trigger) 10 times, but, from the Dashboard --> Last 20 issues it vanishes just after 300 seconds.
My questions are :
What should be the trigger function, I should use? I want to see 10 alerts in zabbix if the same message appears 10 times in the log file within a period of time.
With nodata(300), why does the alert vanish after 300 sec?
Is it ok if I use 30 minutes instead of 300 seconds as an argument of nodata()?
Function logeventid() is normally used for Windows and VMware event logs. In this case, it should probably not be used and it is suspicious that it fires, which might indicate a bug in Zabbix.
Anyway, you can check "Multiple PROBLEM events generation" box in trigger configuration and the trigger will generate a new PROBLEM event every time the condition is true, regardless of its previous value. Instead of logeventid(), you can try using a function that is always true, for instance, strlen()>0.
If you wish the trigger to go into OK state after some time, say, 10 minutes, you can add nodata(10m). Then your trigger will look like this:
{MyTemplate:log[/opt/mylog/logs/abc.log,server starting].strlen()}>0 and
{MyTemplate:log[/opt/mylog/logs/abc.log,server starting].nodata(10m)}=0
Suppose a display file has been declared in a CL program. It accepts some user input and conducts some validations to it. If it fails the validation a message would be displayed on the bottom of the display file. Is it possible to achieve this in CL? I have tried SNDPGMMSG with MSGTYPE(*DIAG), but the message is displayed only after the program has been terminated, and not on the display file during the execution.
The message to be sent is retrieved from message file so using field to display message is not applicable.
Normally we use message subfile to achive what you required above.
It can be done in display file for both CL and RPG
For CL example, you could read here http://www.mcpressonline.com/cl/the-cl-corner-letting-the-user-know-what-s-right-and-wrong.html.
You could search for "cl program message subfile" for other examples
Define a 75 character field in your display file DDS. Call it MESSAGE. In your CL do something like:
if (&option *ge '35') do
CHGVAR &MESSAGE 'Invalid option chosen'
goto getOption
enddo
