While doing my certification in Flowgear I am getting this error while submitting the exercise number 11.
During production run there is no error.
Error - The 'Start' Node was not found in the correct sequence.
This is usually because the Start Node name has been changed. Click the Start Node header, delete the name, press return to commit the changes and try again.

Trying to setup Zabbix to show incomming login failures by syslog log files. I try to create an trigger which triggers when the last value occurs in the last 5 minutes of x amount of items.
The following expression is created:
Code:
count(/Syslog server/log[/var/log/failedlogin.log],5m,"like","last(/Syslog server/log[/var/log/failedlogin.log],#0)")>3
Also the following does not work:
Code:
count(/Syslog server/log[/var/log/failedlogin.log],5m,"like","{ITEM.LASTVALUE}")>3
I'm sure the count function works like it should be, when i fill in de variable manually the item does trigger.
But when i try to get a value out of an other items which is containing the data is seems to not work.
Could someone tell me if this is even possible? Thanks and greetings.
I was using R's RTweet lookup_users to successfully pull data on 6 IDs
test<-c("ID1","ID2","ID3","ID4","ID5","ID6")
detail_followers <- lookup_users(users=test,
parse=TRUE,
token=[bearer_token here],
retryonratelimit=TRUE,
verbose=TRUE)
Update: I created a loop so I could get more visibility on the run, which made it profoundly slow. This would be tolerable, except for two new problems. First, some lookup_user are missing the "profile_banner_url" variable. I built a function to check for this problem and insert a NULL value for those users missing it, further slowing the run.
Finally, many users in this set appear to be bots, as they are deleted within 24 hours of my having just pulled them from the API. The error provided from lookup_users is "Error: $ operator is invalid for atomic vectors". is.atomic eval is not useful, because the fault occurs when lookup_user is called. There are far too many of these fake/suspended/deleted users for manual prompts.
These may be issues with the new RTweet from GitHub.
I am a beginner in zabbix agent.I would like to know if the below trigger is syntactically correct? If yes then how do I know if the trigger is fired ?
I am not able to receive email notifications.Kindly help me .
{MDMCenter:eventlog[761848].iregexp("Job.Execute() failed. (ex.Message = System.Exception: Exception: Failed in Batch: [1] of \[[0-9]*\] ---> System.Exception: Exception: Failed in Batch: [1] of \[[0-9]*\]] ---> System.IO.IOException: The network name cannot be found.")}
The expression as you have it here seems to be invalid - looks like you have accidentally added some example value inside the function parameters.
You can look for the trigger firing on the dashboard or in the Monitoring -> Triggers page.
In general, before even looking at triggers, verify that data is coming in and that the values match your expectations. If some trigger still does not seem to work, always provide exact trigger expression and a few example values, as well as all the things you have checked (server being running, item values being recent and so on).
I want to generate logs with time stamp being in place of popups i have mentioned.
Please suggest some steps for generating logs with time stamp.
Code:-
click("1450851018693.png")
wait(2)
click(Pattern("1450851091319.png").targetOffset(1,2))
click(Pattern("1450851555941.png").targetOffset(-201,1))
type("111")
click(Pattern("1450851201892.png").targetOffset(-13,2))
type("121")
wait(1)
if exists ("1450851253342.png"):
popup("start button is enabled")
click("1450851253342.png")
In the above code instead of popups i want the messages to be logged in file with time stamp.
Please Help..
You can use the logging module from Python importing it and getting a logger instance:
import logging
FORMAT='%(asctime)-15s %(message)s'
logging.basicConfig(format=FORMAT)
logger=logging.getLogger('')
Then, use it in you code (per default, level info is not printed to the console, but warning is)
logger.warning('My message')
You should have a log entry in your like:
2016-03-07 13:10:43,151 My message
See Logging Python for description and basic tutorial.
I have an item of type float, but sometimes a string is received in case of error instead of a number. How can I make a trigger regexp to fire in this case?
I have no idea now to check for "wrong data type".
Actually this is by design and what I'm trying to do is this: if the data gathering fails, I send an error message in order to see it on zabbix end.
I tried with nodata(0), but this doesn't seem to work.
In you case zabbix will not store the "wrong" value for the item. And if you don't care what the string is then you can just setup a trigger for "nodata" for the period of your interval. Look in the triggers manual and search for the "nodata".
Edit: scratch that, didn't read the whole question ....
Edit2: if you are certain that this is not working by design and not because your trigger interval misses the data interval, then you can try to catch the unsupported status. There is an open request for the functionality, but you can setup a side script similar to this. Or you can wrap the monitored item on the node into a UserParameter script that reads the value and prints -1 or something if it is not a number. Then proceed with a normal numeric trigger.
