Hello, 
 I want to check if a process is still running. The process is logging periodically a short info on polling a directory.  
Now, I will to use that info to detect if the process is not running anymore.  
Normally, a simple search for the info would be: 
  search myprocess is doing the work
  
 and then defining the alert for eventcount = 0 would do the job. But...  
I would like to do it in a generic way, that means, that "is doing the work" is actually unknown. This has to work with every process which is logging something periodically. 
 Now, I have a defined a search doing a simple event count over time periods (hourly): 
  source=/logs/processes.log earliest=-3h@h | chart count over process by _time span=1h 
  
 this give me a table like this: 
  process    1381651200    1381654800    1381658400
myproc1    12            12            1
myproc2    15            15            0
myproc3    233           243           102
  
 well, that means that the process "myproc2" did not log anything in the last hour and I need an alert for that issue. 
 What I've tried is to extract somehow the last column and evaluate the apopriate process name (process column) but I couldn't get it done. 
 Any Ideas hot to do that?   
Maybe I'm thinking too complicated? 
 Regards,  
Peter
